[0004] mTOR is a protein kinase that plays a central role in regulating cell growth and proliferation, and is estimated to be overactivated in 30% of cancers. Therapeutic agents targeting mTOR have been widely pursued as potential therapies for cancer, as well as neurological disorders such as epilepsy. However, the success of these therapies is often hampered by insufficient amount of drug that can cross the blood-brain barrier. Even when this condition is met, the application of these drugs is sometimes confounded by the toxicity caused by system-wide inhibition of mTOR (e.g., immunosuppression, hyperglycemia, mucocytis in particular is a class specific effect of all mTOR inhibitors). Disclosed herein, inter alia, are solutions to these and other problems in the art. BRIEF SUMMARY

I. Definitions

[0082] The abbreviations used herein have their conventional meaning within the chemical and biological arts. The chemical structures and formulae set forth herein are constructed according to the standard rules of chemical valency known in the chemical arts. [0083] Where substituent groups are specified by their conventional chemical formulae, written from left to right, they equally encompass the chemically identical substituents that would result from writing the structure from right to left, e.g., -CH ₂ O- is equivalent to -OCH ₂ -. [0084] The term“alkyl,” by itself or as part of another substituent, means, unless otherwise stated, a straight (i.e., unbranched) or branched carbon chain (or carbon), or combination thereof, which may be fully saturated, mono- or polyunsaturated and can include mono-, di-, and multivalent radicals. The alkyl may include a designated number of carbons (e.g., C1-C10 means one to ten carbons). Alkyl is an uncyclized chain. Examples of saturated hydrocarbon radicals include, but are not limited to, groups such as methyl, ethyl, n-propyl, isopropyl, n- butyl, t-butyl, isobutyl, sec-butyl, methyl, homologs and isomers of, for example, n-pentyl, n- hexyl, n-heptyl, n-octyl, and the like. An unsaturated alkyl group is one having one or more double bonds or triple bonds. Examples of unsaturated alkyl groups include, but are not limited to, vinyl, 2-propenyl, crotyl, 2-isopentenyl, 2-(butadienyl), 2,4-pentadienyl, 3-(1,4- pentadienyl), ethynyl, 1- and 3-propynyl, 3-butynyl, and the higher homologs and isomers. An alkoxy is an alkyl attached to the remainder of the molecule via an oxygen linker (-O-). An alkyl moiety may be an alkenyl moiety. An alkyl moiety may be an alkynyl moiety. An alkyl moiety may be fully saturated. An alkenyl may include more than one double bond and/or one or more triple bonds in addition to the one or more double bonds. An alkynyl may include more than one triple bond and/or one or more double bonds in addition to the one or more triple bonds. [0085] The term“alkylene,” by itself or as part of another substituent, means, unless otherwise stated, a divalent radical derived from an alkyl, as exemplified, but not limited by, -CH ₂ CH ₂ CH ₂ CH ₂ -. Typically, an alkyl (or alkylene) group will have from 1 to 24 carbon atoms, with those groups having 10 or fewer carbon atoms being preferred herein. A“lower alkyl” or“lower alkylene” is a shorter chain alkyl or alkylene group, generally having eight or fewer carbon atoms. The term“alkenylene,” by itself or as part of another substituent, means, unless otherwise stated, a divalent radical derived from an alkene. [0086] The term“heteroalkyl,” by itself or in combination with another term, means, unless otherwise stated, a stable straight or branched chain, or combinations thereof, including at least one carbon atom and at least one heteroatom (e.g., O, N, P, Si, and S), and wherein the nitrogen and sulfur atoms may optionally be oxidized, and the nitrogen heteroatom may optionally be quaternized. The heteroatom(s) (e.g., N, S, Si, or P) may be placed at any interior position of the heteroalkyl group or at the position at which the alkyl group is attached to the remainder of the molecule. Heteroalkyl is an uncyclized chain. Examples include, but are not limited to: -CH2-CH2-O-CH3, -CH2-CH2-NH-CH3,

-CH ₂ -CH ₂ -N(CH ₃ )-CH ₃ , -CH ₂ -S-CH ₂ -CH ₃ , -S-CH ₂ -CH ₂ , -S(O)-CH ₃ , -CH ₂ -CH ₂ -S(O) ₂ -CH ₃ , -CH=CH-O-CH ₃ , -Si(CH ₃ ) ₃ , -CH ₂ -CH=N-OCH ₃ , -CH=CH-N(CH ₃ )-CH ₃ , -O-CH ₃ ,

-O-CH2-CH3, and -CN. Up to two or three heteroatoms may be consecutive, such as, for example, -CH ₂ -NH-OCH ₃ and -CH ₂ -O-Si(CH ₃ ) ₃ . A heteroalkyl moiety may include one heteroatom (e.g., O, N, S, Si, or P). A heteroalkyl moiety may include two optionally different heteroatoms (e.g., O, N, S, Si, or P). A heteroalkyl moiety may include three optionally different heteroatoms (e.g., O, N, S, Si, or P). A heteroalkyl moiety may include four optionally different heteroatoms (e.g., O, N, S, Si, or P). A heteroalkyl moiety may include five optionally different heteroatoms (e.g., O, N, S, Si, or P). A heteroalkyl moiety may include up to 8 optionally different heteroatoms (e.g., O, N, S, Si, or P). The term “heteroalkenyl,” by itself or in combination with another term, means, unless otherwise stated, a heteroalkyl including at least one double bond. A heteroalkenyl may optionally include more than one double bond and/or one or more triple bonds in additional to the one or more double bonds. The term“heteroalkynyl,” by itself or in combination with another term, means, unless otherwise stated, a heteroalkyl including at least one triple bond. A

heteroalkynyl may optionally include more than one triple bond and/or one or more double bonds in additional to the one or more triple bonds. [0087] Similarly, the term“heteroalkylene,” by itself or as part of another substituent, means, unless otherwise stated, a divalent radical derived from heteroalkyl, as exemplified, but not limited by, -CH ₂ -CH ₂ -S-CH ₂ -CH ₂ - and -CH ₂ -S-CH ₂ -CH ₂ -NH-CH ₂ -. For

heteroalkylene groups, heteroatoms can also occupy either or both of the chain termini (e.g., alkyleneoxy, alkylenedioxy, alkyleneamino, alkylenediamino, and the like). Still further, for alkylene and heteroalkylene linking groups, no orientation of the linking group is implied by the direction in which the formula of the linking group is written. For example, the formula -C(O)2R'- represents both -C(O)2R'- and -R'C(O)2-. As described above, heteroalkyl groups, as used herein, include those groups that are attached to the remainder of the molecule through a heteroatom, such as -C(O)R', -C(O)NR', -NR'R'', -OR', -SR', and/or -SO ₂ R'. Where “heteroalkyl” is recited, followed by recitations of specific heteroalkyl groups, such as - NR'R'' or the like, it will be understood that the terms heteroalkyl and -NR'R'' are not redundant or mutually exclusive. Rather, the specific heteroalkyl groups are recited to add clarity. Thus, the term“heteroalkyl” should not be interpreted herein as excluding specific heteroalkyl groups, such as -NR'R'' or the like. [0088] The terms“cycloalkyl” and“heterocycloalkyl,” by themselves or in combination with other terms, mean, unless otherwise stated, cyclic versions of“alkyl” and“heteroalkyl,” respectively. Cycloalkyl and heterocycloalkyl are not aromatic. Additionally, for heterocycloalkyl, a heteroatom can occupy the position at which the heterocycle is attached to the remainder of the molecule.

[0092] The terms“halo” or“halogen,” by themselves or as part of another substituent, mean, unless otherwise stated, a fluorine, chlorine, bromine, or iodine atom. Additionally, terms such as“haloalkyl” are meant to include monohaloalkyl and polyhaloalkyl. For example, the term“halo(C ₁ -C ₄ )alkyl” includes, but is not limited to, fluoromethyl, difluoromethyl, trifluoromethyl, 2,2,2-trifluoroethyl, 4-chlorobutyl, 3-bromopropyl, and the like.

[0094] The term“aryl” means, unless otherwise stated, a polyunsaturated, aromatic, hydrocarbon substituent, which can be a single ring or multiple rings (preferably from 1 to 3 rings) that are fused together (i.e., a fused ring aryl) or linked covalently. A fused ring aryl refers to multiple rings fused together wherein at least one of the fused rings is an aryl ring. The term“heteroaryl” refers to aryl groups (or rings) that contain at least one heteroatom such as N, O, or S, wherein the nitrogen and sulfur atoms are optionally oxidized, and the nitrogen atom(s) are optionally quaternized. Thus, the term“heteroaryl” includes fused ring heteroaryl groups (i.e., multiple rings fused together wherein at least one of the fused rings is a heteroaromatic ring). A 5,6-fused ring heteroarylene refers to two rings fused together, wherein one ring has 5 members and the other ring has 6 members, and wherein at least one ring is a heteroaryl ring. Likewise, a 6,6-fused ring heteroarylene refers to two rings fused together, wherein one ring has 6 members and the other ring has 6 members, and wherein at least one ring is a heteroaryl ring.

Substituents for each of the above noted aryl and heteroaryl ring systems are selected from the group of acceptable substituents described below. An“arylene” and a“heteroarylene,” alone or as part of another substituent, mean a divalent radical derived from an aryl and heteroaryl, respectively. A heteroaryl group substituent may be -O- bonded to a ring heteroatom nitrogen. [0095] A fused ring heterocyloalkyl-aryl is an aryl fused to a heterocycloalkyl. A fused ring heterocycloalkyl-heteroaryl is a heteroaryl fused to a heterocycloalkyl. A fused ring heterocycloalkyl-cycloalkyl is a heterocycloalkyl fused to a cycloalkyl.

[0096] Spirocyclic rings are two or more rings wherein adjacent rings are attached through a single atom. The individual rings within spirocyclic rings may be identical or different. Individual rings in spirocyclic rings may be substituted or unsubstituted and may have different substituents from other individual rings within a set of spirocyclic rings. Possible substituents for individual rings within spirocyclic rings are the possible substituents for the same ring when not part of spirocyclic rings (e.g., substituents for cycloalkyl or

heterocycloalkyl rings). Spirocylic rings may be substituted or unsubstituted cycloalkyl, substituted or unsubstituted cycloalkylene, substituted or unsubstituted heterocycloalkyl or substituted or unsubstituted heterocycloalkylene and individual rings within a spirocyclic ring group may be any of the immediately previous list, including having all rings of one type (e.g., all rings being substituted heterocycloalkylene wherein each ring may be the same or different substituted heterocycloalkylene). When referring to a spirocyclic ring system, heterocyclic spirocyclic rings means a spirocyclic rings wherein at least one ring is a heterocyclic ring and wherein each ring may be a different ring. When referring to a spirocyclic ring system, substituted spirocyclic rings means that at least one ring is substituted and each substituent may optionally be different. [0097] The symbol“ ” denotes the point of attachment of a chemical moiety to the remainder of a molecule or chemical formula. [0098] The term“oxo,” as used herein, means an oxygen that is double bonded to a carbon atom. [0099] The term“alkylarylene” as an arylene moiety covalently bonded to an alkylene moiety (also referred to herein as an alkylene linker). In embodiments, the alkylarylene group has the formula: . [0100] An alkylarylene moiety may be substituted (e.g., with a substituent group) on the alkylene moiety or the arylene linker (e.g., at carbons 2, 3, 4, or 6) with halogen, oxo, -N ₃ , -CF3, -CCl3, -CBr3, -CI3, -CN, -CHO, -OH, -NH2, -COOH, -CONH2, -NO2, -SH, -SO2CH3, -SO3H, -OSO3H, -SO2NH2, -NHNH2, -ONH2, -NHC(O)NHNH2, substituted or

unsubstituted C1-C5 alkyl or substituted or unsubstituted 2 to 5 membered heteroalkyl). In embodiments, the alkylarylene is unsubstituted. [0101] Each of the above terms (e.g.,“alkyl,”“heteroalkyl,”“cycloalkyl,”

“heterocycloalkyl,”“aryl,” and“heteroaryl”) includes both substituted and unsubstituted forms of the indicated radical. Preferred substituents for each type of radical are provided below. [0102] Substituents for the alkyl and heteroalkyl radicals (including those groups often referred to as alkylene, alkenyl, heteroalkylene, heteroalkenyl, alkynyl, cycloalkyl, heterocycloalkyl, cycloalkenyl, and heterocycloalkenyl) can be one or more of a variety of groups selected from, but not limited to, -OR', =O, =NR', =N-OR', -NR'R'', -SR', halogen, -SiR'R''R''', -OC(O)R', -C(O)R', -CO2R', -CONR'R'', -OC(O)NR'R'', -NR''C(O)R',

-NR'-C(O)NR''R''', -NR''C(O) ₂ R', -NR-C(NR'R''R''')=NR'''', -NR-C(NR'R'')=NR''', -S(O)R', -S(O)2R', -S(O)2NR'R'', -NRSO2R', -NR'NR''R''', -ONR'R'', -NR'C(O)NR''NR'''R'''', -CN, -NO2, -NR'SO2R'', -NR'C(O)R'', -NR'C(O)-OR'', -NR'OR'', in a number ranging from zero to (2m'+1), where m' is the total number of carbon atoms in such radical. R, R', R'', R''', and R'''' each preferably independently refer to hydrogen, substituted or unsubstituted heteroalkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocycloalkyl, substituted or unsubstituted aryl (e.g., aryl substituted with 1-3 halogens), substituted or unsubstituted heteroaryl, substituted or unsubstituted alkyl, alkoxy, or thioalkoxy groups, or arylalkyl groups. When a compound described herein includes more than one R group, for example, each of the R groups is independently selected as are each R', R'', R''', and R'''' group when more than one of these groups is present. When R' and R'' are attached to the same nitrogen atom, they can be combined with the nitrogen atom to form a 4-, 5-, 6-, or 7- membered ring. For example, -NR'R'' includes, but is not limited to, 1-pyrrolidinyl and 4- morpholinyl. From the above discussion of substituents, one of skill in the art will understand that the term“alkyl” is meant to include groups including carbon atoms bound to groups other than hydrogen groups, such as haloalkyl (e.g., -CF3 and -CH2CF3) and acyl (e.g., -C(O)CH ₃ , -C(O)CF ₃ , -C(O)CH ₂ OCH ₃ , and the like). [0103] Similar to the substituents described for the alkyl radical, substituents for the aryl and heteroaryl groups are varied and are selected from, for example: -OR', -NR'R'', -SR', halogen, -SiR'R''R''', -OC(O)R', -C(O)R', -CO ₂ R', -CONR'R'', -OC(O)NR'R'', -NR''C(O)R', -NR'-C(O)NR''R''', -NR''C(O) ₂ R', -NR-C(NR'R''R''')=NR'''', -NR-C(NR'R'')=NR''', -S(O)R', -S(O)2R', -S(O)2NR'R'', -NRSO2R', -NR'NR''R''', -ONR'R'', -NR'C(O)NR''NR'''R'''', -CN, -NO2, -R', -N3, -CH(Ph)2, fluoro(C1-C4)alkoxy, and fluoro(C1-C4)alkyl, -NR'SO2R'',

-NR'C(O)R'', -NR'C(O)-OR'', -NR'OR'', in a number ranging from zero to the total number of open valences on the aromatic ring system; and where R', R'', R''', and R'''' are preferably independently selected from hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted heteroalkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocycloalkyl, substituted or unsubstituted aryl, and substituted or unsubstituted heteroaryl. When a compound described herein includes more than one R group, for example, each of the R groups is independently selected as are each R', R'', R''', and R'''' groups when more than one of these groups is present. [0104] Substituents for rings (e.g., cycloalkyl, heterocycloalkyl, aryl, heteroaryl, cycloalkylene, heterocycloalkylene, arylene, or heteroarylene) may be depicted as substituents on the ring rather than on a specific atom of a ring (commonly referred to as a floating substituent). In such a case, the substituent may be attached to any of the ring atoms (obeying the rules of chemical valency) and in the case of fused rings or spirocyclic rings, a substituent depicted as associated with one member of the fused rings or spirocyclic rings (a floating substituent on a single ring), may be a substituent on any of the fused rings or spirocyclic rings (a floating substituent on multiple rings). When a substituent is attached to a ring, but not a specific atom (a floating substituent), and a subscript for the substituent is an integer greater than one, the multiple substituents may be on the same atom, same ring, different atoms, different fused rings, different spirocyclic rings, and each substituent may optionally be different. Where a point of attachment of a ring to the remainder of a molecule is not limited to a single atom (a floating substituent), the attachment point may be any atom of the ring and in the case of a fused ring or spirocyclic ring, any atom of any of the fused rings or spirocyclic rings while obeying the rules of chemical valency. Where a ring, fused rings, or spirocyclic rings contain one or more ring heteroatoms and the ring, fused rings, or spirocyclic rings are shown with one more floating substituents (including, but not limited to, points of attachment to the remainder of the molecule), the floating substituents may be bonded to the heteroatoms. Where the ring heteroatoms are shown bound to one or more hydrogens (e.g., a ring nitrogen with two bonds to ring atoms and a third bond to a hydrogen) in the structure or formula with the floating substituent, when the heteroatom is bonded to the floating substituent, the substituent will be understood to replace the hydrogen, while obeying the rules of chemical valency. [0105] Two or more substituents may optionally be joined to form aryl, heteroaryl, cycloalkyl, or heterocycloalkyl groups. Such so-called ring-forming substituents are typically, though not necessarily, found attached to a cyclic base structure. In one embodiment, the ring-forming substituents are attached to adjacent members of the base structure. For example, two ring-forming substituents attached to adjacent members of a cyclic base structure create a fused ring structure. In another embodiment, the ring-forming substituents are attached to a single member of the base structure. For example, two ring- forming substituents attached to a single member of a cyclic base structure create a spirocyclic structure. In yet another embodiment, the ring-forming substituents are attached to non-adjacent members of the base structure. [0106] Two of the substituents on adjacent atoms of the aryl or heteroaryl ring may optionally form a ring of the formula -T-C(O)-(CRR')q-U-, wherein T and U are

independently -NR-, -O-, -CRR'-, or a single bond, and q is an integer of from 0 to 3.

Alternatively, two of the substituents on adjacent atoms of the aryl or heteroaryl ring may optionally be replaced with a substituent of the formula -A-(CH2)r-B-, wherein A and B are independently -CRR'-, -O-, -NR-, -S-, -S(O) -, -S(O) ₂ -, -S(O) ₂ NR'-, or a single bond, and r is an integer of from 1 to 4. One of the single bonds of the new ring so formed may optionally be replaced with a double bond. Alternatively, two of the substituents on adjacent atoms of the aryl or heteroaryl ring may optionally be replaced with a substituent of the formula -(CRR') _s -X'- (C''R''R''') _d -, where s and d are independently integers of from 0 to 3, and X' is -O-, -NR'-, -S-, -S(O)-, -S(O)2-, or -S(O)2NR'-. The substituents R, R', R'', and R''' are preferably independently selected from hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted heteroalkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocycloalkyl, substituted or unsubstituted aryl, and substituted or unsubstituted heteroaryl. [0107] As used herein, the terms“heteroatom” or“ring heteroatom” are meant to include oxygen (O), nitrogen (N), sulfur (S), phosphorus (P), and silicon (Si).

[0119] Certain compounds of the present disclosure possess asymmetric carbon atoms (optical or chiral centers) or double bonds; the enantiomers, racemates, diastereomers, tautomers, geometric isomers, stereoisometric forms that may be defined, in terms of absolute stereochemistry, as (R)-or (S)- or, as (D)- or (L)- for amino acids, and individual isomers are encompassed within the scope of the present disclosure. The compounds of the present disclosure do not include those that are known in art to be too unstable to synthesize and/or isolate. The present disclosure is meant to include compounds in racemic and optically pure forms. Optically active (R)- and (S)-, or (D)- and (L)-isomers may be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques. When the compounds described herein contain olefinic bonds or other centers of geometric asymmetry, and unless specified otherwise, it is intended that the compounds include both E and Z geometric isomers. [0120] As used herein, the term“isomers” refers to compounds having the same number and kind of atoms, and hence the same molecular weight, but differing in respect to the structural arrangement or configuration of the atoms. [0121] The term“tautomer,” as used herein, refers to one of two or more structural isomers which exist in equilibrium and which are readily converted from one isomeric form to another. [0122] It will be apparent to one skilled in the art that certain compounds of this disclosure may exist in tautomeric forms, all such tautomeric forms of the compounds being within the scope of the disclosure. [0123] Unless otherwise stated, structures depicted herein are also meant to include all stereochemical forms of the structure; i.e., the R and S configurations for each asymmetric center. Therefore, single stereochemical isomers as well as enantiomeric and diastereomeric mixtures of the present compounds are within the scope of the disclosure. [0124] Unless otherwise stated, structures depicted herein are also meant to include compounds which differ only in the presence of one or more isotopically enriched atoms. For example, compounds having the present structures except for the replacement of a hydrogen by a deuterium or tritium, or the replacement of a carbon by ¹³ C- or ¹⁴ C-enriched carbon are within the scope of this disclosure. [0125] The compounds of the present disclosure may also contain unnatural proportions of atomic isotopes at one or more of the atoms that constitute such compounds. For example, the compounds may be radiolabeled with radioactive isotopes, such as for example tritium ( ³ H), iodine-125 ( ¹²⁵ I), or carbon-14 ( ¹⁴ C). All isotopic variations of the compounds of the present disclosure, whether radioactive or not, are encompassed within the scope of the present disclosure. [0126] It should be noted that throughout the application that alternatives are written in Markush groups, for example, each amino acid position that contains more than one possible amino acid. It is specifically contemplated that each member of the Markush group should be considered separately, thereby comprising another embodiment, and the Markush group is not to be read as a single unit. [0127] As used herein, the terms“bioconjugate” and“bioconjugate linker” refer to the resulting association between atoms or molecules of bioconjugate reactive groups or bioconjugate reactive moieties. The association can be direct or indirect. For example, a conjugate between a first bioconjugate reactive group (e.g.,–NH ₂ ,–COOH,–N- hydroxysuccinimide, or–maleimide) and a second bioconjugate reactive group (e.g., sulfhydryl, sulfur-containing amino acid, amine, amine sidechain containing amino acid, or carboxylate) provided herein can be direct, e.g., by covalent bond or linker (e.g., a first linker of second linker), or indirect, e.g., by non-covalent bond (e.g., electrostatic interactions (e.g., ionic bond, hydrogen bond, halogen bond), van der Waals interactions (e.g., dipole-dipole, dipole-induced dipole, London dispersion), ring stacking (pi effects), hydrophobic interactions and the like). In embodiments, bioconjugates or bioconjugate linkers are formed using bioconjugate chemistry (i.e., the association of two bioconjugate reactive groups) including, but are not limited to nucleophilic substitutions (e.g., reactions of amines and alcohols with acyl halides, active esters), electrophilic substitutions (e.g., enamine reactions) and additions to carbon-carbon and carbon-heteroatom multiple bonds (e.g., Michael reaction, Diels-Alder addition). These and other useful reactions are discussed in, for example, March, ADVANCED ORGANIC CHEMISTRY, 3rd Ed., John Wiley & Sons, New York, 1985; Hermanson, BIOCONJUGATE TECHNIQUES, Academic Press, San Diego, 1996; and Feeney et al., MODIFICATION OF PROTEINS; Advances in Chemistry Series, Vol.198, American Chemical Society, Washington, D.C., 1982. In embodiments, the first bioconjugate reactive group (e.g., maleimide moiety) is covalently attached to the second bioconjugate reactive group (e.g., a sulfhydryl). In embodiments, the first bioconjugate reactive group (e.g., haloacetyl moiety) is covalently attached to the second bioconjugate reactive group (e.g., a sulfhydryl). In embodiments, the first bioconjugate reactive group (e.g., pyridyl moiety) is covalently attached to the second bioconjugate reactive group (e.g., a sulfhydryl). In embodiments, the first bioconjugate reactive group (e.g.,–N- hydroxysuccinimide moiety) is covalently attached to the second bioconjugate reactive group (e.g. an amine). In embodiments, the first bioconjugate reactive group (e.g., maleimide moiety) is covalently attached to the second bioconjugate reactive group (e.g., a sulfhydryl). In embodiments, the first bioconjugate reactive group (e.g.,–sulfo–N-hydroxysuccinimide moiety) is covalently attached to the second bioconjugate reactive group (e.g., an amine). [0128] Useful bioconjugate reactive moieties used for bioconjugate chemistries herein include, for example: (a) carboxyl groups and various derivatives thereof including, but not limited to, N- hydroxysuccinimide esters, N-hydroxybenztriazole esters, acid halides, acyl imidazoles, thioesters, p-nitrophenyl esters, alkyl, alkenyl, alkynyl and aromatic esters; (b) hydroxyl groups which can be converted to esters, ethers, aldehydes, etc.; (c) haloalkyl groups wherein the halide can be later displaced with a nucleophilic group such as, for example, an amine, a carboxylate anion, thiol anion, carbanion, or an alkoxide ion, thereby resulting in the covalent attachment of a new group at the site of the halogen atom; (d) dienophile groups which are capable of participating in Diels-Alder reactions such as, for example, maleimido or maleimide groups; (e) aldehyde or ketone groups such that subsequent derivatization is possible via formation of carbonyl derivatives such as, for example, imines, hydrazones, semicarbazones or oximes, or via such mechanisms as Grignard addition or alkyllithium addition; (f) sulfonyl halide groups for subsequent reaction with amines, for example, to form sulfonamides; (g) thiol groups, which can be converted to disulfides, reacted with acyl halides, or bonded to metals such as gold, or react with maleimides; (h) amine or sulfhydryl groups (e.g., present in cysteine), which can be, for example, acylated, alkylated or oxidized; (i) alkenes, which can undergo, for example, cycloadditions, acylation, Michael addition, etc; (j) epoxides, which can react with, for example, amines and hydroxyl compounds; (k) phosphoramidites and other standard functional groups useful in nucleic acid synthesis; (l) metal silicon oxide bonding; (m) metal bonding to reactive phosphorus groups (e.g., phosphines) to form, for example, phosphate diester bonds; (n) azides coupled to alkynes using copper catalyzed cycloaddition click chemistry; and (o) biotin conjugate can react with avidin or strepavidin to form a avidin-biotin complex or streptavidin-biotin complex. [0129] The bioconjugate reactive groups can be chosen such that they do not participate in, or interfere with, the chemical stability of the conjugate described herein. Alternatively, a reactive functional group can be protected from participating in the crosslinking reaction by the presence of a protecting group. In embodiments, the bioconjugate comprises a molecular entity derived from the reaction of an unsaturated bond, such as a maleimide, and a sulfhydryl group. [0130] “Analog,”“analogue,” or“derivative” is used in accordance with its plain ordinary meaning within Chemistry and Biology and refers to a chemical compound that is structurally similar to another compound (i.e., a so-called“reference” compound) but differs in composition, e.g., in the replacement of one atom by an atom of a different element, or in the presence of a particular functional group, or the replacement of one functional group by another functional group, or the absolute stereochemistry of one or more chiral centers of the reference compound. Accordingly, an analog is a compound that is similar or comparable in function and/or appearance but not in structure or origin to a reference compound. [0131] The terms“a” or“an,” as used in herein means one or more. In addition, the phrase “substituted with a[n],” as used herein, means the specified group may be substituted with one or more of any or all of the named substituents. For example, where a group, such as an alkyl or heteroaryl group, is“substituted with an unsubstituted C1-C20 alkyl, or unsubstituted 2 to 20 membered heteroalkyl,” the group may contain one or more unsubstituted C1-C20 alkyls, and/or one or more unsubstituted 2 to 20 membered heteroalkyls. [0132] Moreover, where a moiety is substituted with an R substituent, the group may be referred to as“R-substituted.” Where a moiety is R-substituted, the moiety is substituted with at least one R substituent and each R substituent is optionally different. Where a particular R group is present in the description of a chemical genus (such as Formula (I)), a Roman alphabetic symbol may be used to distinguish each appearance of that particular R group. For example, where multiple R ¹³ substituents are present, each R ¹³ substituent may be distinguished as R ^13A , R ^13B , R ^13C , R ^13D , etc., wherein each of R ^13A , R ^13B , R ^13C , R ^13D , etc. is defined within the scope of the definition of R ¹³ and optionally differently. [0133] A“detectable agent” or“detectable moiety” is a composition, substance, element, or compound; or moiety thereof; detectable by appropriate means such as spectroscopic, photochemical, biochemical, immunochemical, chemical, magnetic resonance imaging, or other physical means.

[0135] Descriptions of compounds of the present disclosure are limited by principles of chemical bonding known to those skilled in the art. Accordingly, where a group may be substituted by one or more of a number of substituents, such substitutions are selected so as to comply with principles of chemical bonding and to give compounds which are not inherently unstable and/or would be known to one of ordinary skill in the art as likely to be unstable under ambient conditions, such as aqueous, neutral, and several known physiological conditions. For example, a heterocycloalkyl or heteroaryl is attached to the remainder of the molecule via a ring heteroatom in compliance with principles of chemical bonding known to those skilled in the art thereby avoiding inherently unstable compounds. [0136] The term“pharmaceutically acceptable salts” is meant to include salts of the active compounds that are prepared with relatively nontoxic acids or bases, depending on the particular substituents found on the compounds described herein. When compounds of the present disclosure contain relatively acidic functionalities, base addition salts can be obtained by contacting the neutral form of such compounds with a sufficient amount of the desired base, either neat or in a suitable inert solvent. Examples of pharmaceutically acceptable base addition salts include sodium, potassium, calcium, ammonium, organic amino, or magnesium salt, or a similar salt. When compounds of the present disclosure contain relatively basic functionalities, acid addition salts can be obtained by contacting the neutral form of such compounds with a sufficient amount of the desired acid, either neat or in a suitable inert solvent. Examples of pharmaceutically acceptable acid addition salts include those derived from inorganic acids like hydrochloric, hydrobromic, nitric, carbonic,

monohydrogencarbonic, phosphoric, monohydrogenphosphoric, dihydrogenphosphoric, sulfuric, monohydrogensulfuric, hydriodic, or phosphorous acids and the like, as well as the salts derived from relatively nontoxic organic acids like acetic, propionic, isobutyric, maleic, malonic, benzoic, succinic, suberic, fumaric, lactic, mandelic, phthalic, benzenesulfonic, p- tolylsulfonic, citric, tartaric, oxalic, methanesulfonic, and the like. Also included are salts of amino acids such as arginate and the like, and salts of organic acids like glucuronic or galactunoric acids and the like (see, for example, Berge et al.,“Pharmaceutical Salts”, Journal of Pharmaceutical Science, 1977, 66, 1-19). Certain specific compounds of the present disclosure contain both basic and acidic functionalities that allow the compounds to be converted into either base or acid addition salts. [0137] Thus, the compounds of the present disclosure may exist as salts, such as with pharmaceutically acceptable acids. The present disclosure includes such salts. Non-limiting examples of such salts include hydrochlorides, hydrobromides, phosphates, sulfates, methanesulfonates, nitrates, maleates, acetates, citrates, fumarates, propionates, tartrates (e.g., (+)-tartrates, (-)-tartrates, or mixtures thereof including racemic mixtures), succinates, benzoates, and salts with amino acids such as glutamic acid, and quaternary ammonium salts (e.g., methyl iodide, ethyl iodide, and the like). These salts may be prepared by methods known to those skilled in the art. [0138] The neutral forms of the compounds are preferably regenerated by contacting the salt with a base or acid and isolating the parent compound in the conventional manner. The parent form of the compound may differ from the various salt forms in certain physical properties, such as solubility in polar solvents. [0139] In addition to salt forms, the present disclosure provides compounds, which are in a prodrug form. Prodrugs of the compounds described herein are those compounds that readily undergo chemical changes under physiological conditions to provide the compounds of the present disclosure. Prodrugs of the compounds described herein may be converted in vivo after administration. Additionally, prodrugs can be converted to the compounds of the present disclosure by chemical or biochemical methods in an ex vivo environment, such as, for example, when contacted with a suitable enzyme or chemical reagent. [0140] Certain compounds of the present disclosure can exist in unsolvated forms as well as solvated forms, including hydrated forms. In general, the solvated forms are equivalent to unsolvated forms and are encompassed within the scope of the present disclosure. Certain compounds of the present disclosure may exist in multiple crystalline or amorphous forms. In general, all physical forms are equivalent for the uses contemplated by the present disclosure and are intended to be within the scope of the present disclosure. [0141] Compounds or functional moieties are“polar” when there are opposing charges (i.e., having partial positive and partial negative charges) from polar bonds arranged asymmetrically. The polarity of a molecule can be measured, for example, by its partition coefficient, P, defined as the ratio of the concentrations of a solute between two immiscible solvents. When one of the solvents is water, the clogP value is a measure of lipophilicity or hydrophobicity. In embodiments, the compound has a clogP of about 5. In embodiments, the compound has a clogP of less than 5. Polarity can also be measured, for example, by ts topological polar surface area (PSA), which is the surface sum over all polar atoms, primarily oxygen and nitrogen, also including their attached hydrogen atoms. Molecules with a PSA of greater than 140 Å tend to be poor at permeating cell membraines. In embodiments, for molecules to penetrate the blood-brain barrier, a PSA less than 90 Å is usually necessary. In embodiments, the compound described herein has a PSA between 90 Å and 140 Å. In embodiments, the compound described herein has a PSA between 100 Å and 140 Å. [0142] A polypeptide, or a cell is“recombinant” when it is artificial or engineered, or derived from or contains an artificial or engineered protein or nucleic acid (e.g., non-natural or not wild type). For example, a polynucleotide that is inserted into a vector or any other heterologous location, e.g., in a genome of a recombinant organism, such that it is not associated with nucleotide sequences that normally flank the polynucleotide as it is found in nature is a recombinant polynucleotide. A protein expressed in vitro or in vivo from a recombinant polynucleotide is an example of a recombinant polypeptide. Likewise, a polynucleotide sequence that does not appear in nature, for example a variant of a naturally occurring gene, is recombinant. [0143] As used herein, the term“about” means a range of values including the specified value, which a person of ordinary skill in the art would consider reasonably similar to the specified value. In embodiments, about means within a standard deviation using

measurements generally acceptable in the art. In embodiments, about means a range extending to +/- 10% of the specified value. In embodiments, about includes the specified value. [0144] “Co-administer” is meant that a composition described herein is administered at the same time, just prior to, or just after the administration of one or more additional therapies. The compounds of the invention can be administered alone or can be co-administered to the patient. Co-administration is meant to include simultaneous or sequential administration of the compounds individually or in combination (more than one compound). Thus, the preparations can also be combined, when desired, with other active substances (e.g., to reduce metabolic degradation). The compositions of the present invention can be delivered transdermally, by a topical route, or formulated as applicator sticks, solutions, suspensions, emulsions, gels, creams, ointments, pastes, jellies, paints, powders, and aerosols. [0145] A“cell” as used herein, refers to a cell carrying out metabolic or other function sufficient to preserve or replicate its genomic DNA. A cell can be identified by well-known methods in the art including, for example, presence of an intact membrane, staining by a particular dye, ability to produce progeny or, in the case of a gamete, ability to combine with a second gamete to produce a viable offspring. Cells may include prokaryotic and eukaroytic cells. Prokaryotic cells include but are not limited to bacteria. Eukaryotic cells include but are not limited to yeast cells and cells derived from plants and animals, for example mammalian, insect (e.g., spodoptera) and human cells. Cells may be useful when they are naturally nonadherent or have been treated not to adhere to surfaces, for example by trypsinization. [0146] The terms“treating” or“treatment” refers to any indicia of success in the treatment or amelioration of an injury, disease, pathology or condition, including any objective or subjective parameter such as abatement; remission; diminishing of symptoms or making the injury, pathology or condition more tolerable to the patient; slowing in the rate of

degeneration or decline; making the final point of degeneration less debilitating; improving a patient’s physical or mental well-being. The treatment or amelioration of symptoms can be based on objective or subjective parameters; including the results of a physical examination, neuropsychiatric exams, and/or a psychiatric evaluation. For example, the certain methods presented herein successfully treat cancer by decreasing the incidence of cancer and or causing remission of cancer. In some embodiments of the compositions or methods described herein, treating cancer includes slowing the rate of growth or spread of cancer cells, reducing metastasis, or reducing the growth of metastatic tumors. The term“treating” and conjugations thereof, include prevention of an injury, pathology, condition, or disease. In embodiments, treating is preventing. In embodiments, treating does not include preventing. In embodiments, the treating or treatment is no prophylactic treatment. [0147] An“effective amount” is an amount sufficient for a compound to accomplish a stated purpose relative to the absence of the compound (e.g., achieve the effect for which it is administered, treat a disease, reduce enzyme activity, increase enzyme activity, reduce signaling pathway, reduce one or more symptoms of a disease or condition. An example of an“effective amount” is an amount sufficient to contribute to the treatment, prevention, or reduction of a symptom or symptoms of a disease, which could also be referred to as a “therapeutically effective amount” when referred to in this context. A“reduction” of a symptom or symptoms (and grammatical equivalents of this phrase) means decreasing of the severity or frequency of the symptom(s), or elimination of the symptom(s). A

“prophylactically effective amount” of a drug is an amount of a drug that, when administered to a subject, will have the intended prophylactic effect, e.g., preventing or delaying the onset (or reoccurrence) of an injury, disease, pathology or condition, or reducing the likelihood of the onset (or reoccurrence) of an injury, disease, pathology, or condition, or their symptoms. The full prophylactic effect does not necessarily occur by administration of one dose, and may occur only after administration of a series of doses. Thus, a prophylactically effective amount may be administered in one or more administrations. An“activity decreasing amount,” as used herein, refers to an amount of antagonist required to decrease the activity of an enzyme relative to the absence of the antagonist. A“function disrupting amount,” as used herein, refers to the amount of antagonist required to disrupt the function of an enzyme or protein relative to the absence of the antagonist. The exact amounts will depend on the purpose of the treatment, and will be ascertainable by one skilled in the art using known techniques (see, e.g., Lieberman, Pharmaceutical Dosage Forms (vols.1-3, 1992); Lloyd, The Art, Science and Technology of Pharmaceutical Compounding (1999); Pickar, Dosage Calculations (1999); and Remington: The Science and Practice of Pharmacy, 20th Edition, 2003, Gennaro, Ed., Lippincott, Williams & Wilkins). [0148] “Control” or“control experiment” is used in accordance with its plain ordinary meaning and refers to an experiment in which the subjects or reagents of the experiment are treated as in a parallel experiment except for omission of a procedure, reagent, or variable of the experiment. In some instances, the control is used as a standard of comparison in evaluating experimental effects. In some embodiments, a control is the measurement of the activity (e.g., signaling pathway) of a protein in the absence of a compound as described herein (including embodiments, examples, figures, or Tables). [0149] “Contacting” is used in accordance with its plain ordinary meaning and refers to the process of allowing at least two distinct species (e.g., chemical compounds including biomolecules, or cells) to become sufficiently proximal to react, interact or physically touch. It should be appreciated; however, the resulting reaction product can be produced directly from a reaction between the added reagents or from an intermediate from one or more of the added reagents which can be produced in the reaction mixture. [0150] The term“contacting” may include allowing two species to react, interact, or physically touch, wherein the two species may be a compound as described herein and a cellular component (e.g., protein, ion, lipid, nucleic acid, nucleotide, amino acid, protein, particle, organelle, cellular compartment, microorganism, virus, lipid droplet, vesicle, small molecule, protein complex, protein aggregate, or macromolecule). In some embodiments contacting includes allowing a compound described herein to interact with a cellular component (e.g., protein, ion, lipid, nucleic acid, nucleotide, amino acid, protein, particle, virus, lipid droplet, organelle, cellular compartment, microorganism, vesicle, small molecule, protein complex, protein aggregate, or macromolecule) that is involved in a signaling pathway. [0151] As defined herein, the term“inhibition,”“inhibit,”“inhibiting” and the like in reference to a cellular component-inhibitor interaction means negatively affecting (e.g., decreasing) the activity or function of the cellular component (e.g., decreasing the signaling pathway stimulated by a cellular component (e.g., protein, ion, lipid, virus, lipid droplet, nucleic acid, nucleotide, amino acid, protein, particle, organelle, cellular compartment, microorganism, vesicle, small molecule, protein complex, protein aggregate, or

macromolecule)), relative to the activity or function of the cellular component in the absence of the inhibitor. In some embodiments inhibition refers to reduction of a disease or symptoms of disease. In some embodiments, inhibition refers to a reduction in the activity of a signal transduction pathway or signaling pathway (e.g., reduction of a pathway involving the cellular component). Thus, inhibition includes, at least in part, partially or totally blocking stimulation, decreasing, preventing, or delaying activation, or inactivating, desensitizing, or down-regulating the signaling pathway or enzymatic activity or the amount of a cellular component. [0152] The term“modulator” refers to a composition that increases or decreases the level of a target molecule or the function of a target molecule or the physical state of the target of the molecule (e.g., a target may be a cellular component (e.g., protein, ion, lipid, virus, lipid droplet, nucleic acid, nucleotide, amino acid, protein, particle, organelle, cellular compartment, microorganism, vesicle, small molecule, protein complex, protein aggregate, or macromolecule)) relative to the absence of the composition. [0153] The term“modulate” is used in accordance with its plain ordinary meaning and refers to the act of changing or varying one or more properties.“Modulation” refers to the process of changing or varying one or more properties. For example, as applied to the effects of a modulator on a target protein, to modulate means to change by increasing or decreasing a property or function of the target molecule or the amount of the target molecule. [0154] “Patient” or“subject in need thereof” refers to a living organism suffering from or prone to a disease or condition that can be treated by administration of a pharmaceutical composition as provided herein. Non-limiting examples include humans, other mammals, bovines, rats, mice, dogs, monkeys, goat, sheep, cows, deer, and other non-mammalian animals. In some embodiments, a patient is human. [0155] “Disease” or“condition” refer to a state of being or health status of a patient or subject capable of being treated with the compounds or methods provided herein. In some embodiments, the disease is a disease related to (e.g., caused by) a cellular component (e.g., protein, ion, lipid, nucleic acid, nucleotide, amino acid, protein, particle, organelle, cellular compartment, microorganism, vesicle, small molecule, protein complex, protein aggregate, or macromolecule). [0156] As used herein, the term“cancer” refers to all types of cancer, neoplasm or malignant tumors found in mammals (e.g., humans), including leukemia, lymphoma, carcinomas and sarcomas. Exemplary cancers that may be treated with a compound or method provided herein include cancer of the thyroid, endocrine system, brain, breast, cervix, colon, head & neck, liver, kidney, lung, non-small cell lung, melanoma, mesothelioma, ovary, sarcoma, stomach, uterus, Medulloblastoma, colorectal cancer, pancreatic cancer.

[0158] As used herein, the term“lymphoma” refers to a group of cancers affecting hematopoietic and lymphoid tissues. It begins in lymphocytes, the blood cells that are found primarily in lymph nodes, spleen, thymus, and bone marrow. Two main types of lymphoma are non-Hodgkin lymphoma and Hodgkin’s disease. Hodgkin’s disease represents approximately 15% of all diagnosed lymphomas. This is a cancer associated with Reed- Sternberg malignant B lymphocytes. Non-Hodgkin’s lymphomas (NHL) can be classified based on the rate at which cancer grows and the type of cells involved. There are aggressive (high grade) and indolent (low grade) types of NHL. Based on the type of cells involved, there are B-cell and T-cell NHLs. Exemplary B-cell lymphomas that may be treated with a compound or method provided herein include, but are not limited to, small lymphocytic lymphoma, Mantle cell lymphoma, follicular lymphoma, marginal zone lymphoma, extranodal (MALT) lymphoma, nodal (monocytoid B-cell) lymphoma, splenic lymphoma, diffuse large cell B-lymphoma, Burkitt’s lymphoma, lymphoblastic lymphoma,

[0162] As used herein, the terms“metastasis,”“metastatic,” and“metastatic cancer” can be used interchangeably and refer to the spread of a proliferative disease or disorder, e.g., cancer, from one organ or another non-adjacent organ or body part.“Metastatic cancer” is also called“Stage IV cancer.” Cancer occurs at an originating site, e.g., breast, which site is referred to as a primary tumor, e.g., primary breast cancer. Some cancer cells in the primary tumor or originating site acquire the ability to penetrate and infiltrate surrounding normal tissue in the local area and/or the ability to penetrate the walls of the lymphatic system or vascular system circulating through the system to other sites and tissues in the body. A second clinically detectable tumor formed from cancer cells of a primary tumor is referred to as a metastatic or secondary tumor. When cancer cells metastasize, the metastatic tumor and its cells are presumed to be similar to those of the original tumor. Thus, if lung cancer metastasizes to the breast, the secondary tumor at the site of the breast consists of abnormal lung cells and not abnormal breast cells. The secondary tumor in the breast is referred to a metastatic lung cancer. Thus, the phrase metastatic cancer refers to a disease in which a subject has or had a primary tumor and has one or more secondary tumors. The phrases non- metastatic cancer or subjects with cancer that is not metastatic refers to diseases in which subjects have a primary tumor but not one or more secondary tumors. For example, metastatic lung cancer refers to a disease in a subject with or with a history of a primary lung tumor and with one or more secondary tumors at a second location or multiple locations, e.g., in the breast.

[0163] The terms“cutaneous metastasis” or“skin metastasis” refer to secondary malignant cell growths in the skin, wherein the malignant cells originate from a primary cancer site (e.g., breast). In cutaneous metastasis, cancerous cells from a primary cancer site may migrate to the skin where they divide and cause lesions. Cutaneous metastasis may result from the migration of cancer cells from breast cancer tumors to the skin.

[0164] The term“visceral metastasis” refer to secondary malignant cell growths in the interal organs (e.g., heart, lungs, liver, pancreas, intestines) or body cavities (e.g., pleura, peritoneum), wherein the malignant cells originate from a primary cancer site (e.g., head and neck, liver, breast). In visceral metastasis, cancerous cells from a primary cancer site may migrate to the internal organs where they divide and cause lesions. Visceral metastasis may result from the migration of cancer cells from liver cancer tumors or head and neck tumors to internal organs. [0165] As used herein, the term“autoimmune disease” refers to a disease or condition in which a subject’s immune system has an aberrant immune response against a substance that does not normally elicit an immune response in a healthy subject. Examples of autoimmune diseases that may be treated with a compound, pharmaceutical composition, or method described herein include Acute Disseminated Encephalomyelitis (ADEM), Acute necrotizing hemorrhagic leukoencephalitis, Addison’s disease, Agammaglobulinemia, Alopecia areata, Amyloidosis, Ankylosing spondylitis, Anti-GBM/Anti-TBM nephritis, Antiphospholipid syndrome (APS), Autoimmune angioedema, Autoimmune aplastic anemia, Autoimmune dysautonomia, Autoimmune hepatitis, Autoimmune hyperlipidemia, Autoimmune immunodeficiency, Autoimmune inner ear disease (AIED), Autoimmune myocarditis, Autoimmune oophoritis, Autoimmune pancreatitis, Autoimmune retinopathy, Autoimmune thrombocytopenic purpura (ATP), Autoimmune thyroid disease, Autoimmune urticaria, Axonal or neuronal neuropathies, Balo disease, Behcet’s disease, Bullous pemphigoid, Cardiomyopathy, Castleman disease, Celiac disease, Chagas disease, Chronic fatigue syndrome, Chronic inflammatory demyelinating polyneuropathy (CIDP), Chronic recurrent multifocal ostomyelitis (CRMO), Churg-Strauss syndrome, Cicatricial pemphigoid/benign mucosal pemphigoid, Crohn’s disease, Cogans syndrome, Cold agglutinin disease,

[0170] As used herein, the term“metabolic disease” or“metabolic disorder” refers to a disease or condition in which a subject’s metabolism or metabolic system (e.g., function of storing or utilizing energy) becomes impaired. Examples of metabolic diseases that may be treated with a compound, pharmaceutical composition, or method described herein include diabetes (e.g., type I or type II), obesity, metabolic syndrome, or a mitochondrial disease (e.g., dysfunction of mitochondria or aberrant mitochondrial function). [0171] The term“cellular component associated disease” (e.g., the cellular component may be a protein, ion, lipid, nucleic acid, nucleotide, amino acid, protein, particle, organelle, cellular compartment, microorganism, virus, vesicle, small molecule, protein complex, protein aggregate, or macromolecule; the disease may be a neurodegenerative disease, cancer, a metabolic disease, autoimmune disease, inflammatory disease, or infectious disease) (also referred to herein as“cellular component related disease”) refers to a disease caused by the celllular component. Other diseases that are associated with aberrant activity or level of the cellular component are well known in the art and determining such diseases are within the skill of a person of skill in the art. [0172] “Pharmaceutically acceptable excipient” and“pharmaceutically acceptable carrier” refer to a substance that aids the administration of an active agent to and absorption by a subject and can be included in the compositions of the present invention without causing a significant adverse toxicological effect on the patient. Non-limiting examples of

pharmaceutically acceptable excipients include water, NaCl, normal saline solutions, lactated Ringer’s, normal sucrose, normal glucose, binders, fillers, disintegrants, lubricants, coatings, sweeteners, flavors, salt solutions (such as Ringer's solution), alcohols, oils, gelatins, carbohydrates such as lactose, amylose or starch, fatty acid esters, hydroxymethycellulose, polyvinyl pyrrolidine, and colors, and the like. Such preparations can be sterilized and, if desired, mixed with auxiliary agents such as lubricants, preservatives, stabilizers, wetting agents, emulsifiers, salts for influencing osmotic pressure, buffers, coloring, and/or aromatic substances and the like that do not deleteriously react with the compounds of the invention. One of skill in the art will recognize that other pharmaceutical excipients are useful in the present invention. [0173] The term“preparation” is intended to include the formulation of the active compound with encapsulating material as a carrier providing a capsule in which the active component with or without other carriers, is surrounded by a carrier, which is thus in association with it. Similarly, cachets and lozenges are included. Tablets, powders, capsules, pills, cachets, and lozenges can be used as solid dosage forms suitable for oral administration. [0174] As used herein, the term“administering” means oral administration, administration as a suppository, topical contact, intravenous, intraperitoneal, intramuscular, intralesional, intrathecal, intranasal or subcutaneous administration, or the implantation of a slow-release device, e.g., a mini-osmotic pump, to a subject. Administration is by any route, including parenteral and transmucosal (e.g., buccal, sublingual, palatal, gingival, nasal, vaginal, rectal, or transdermal). Parenteral administration includes, e.g., intravenous, intramuscular, intra- arteriole, intradermal, subcutaneous, intraperitoneal, intraventricular, and intracranial. Other modes of delivery include, but are not limited to, the use of liposomal formulations, intravenous infusion, transdermal patches, etc. By“co-administer” it is meant that a composition described herein is administered at the same time, just prior to, or just after the administration of one or more additional therapies, for example cancer therapies such as chemotherapy, hormonal therapy, radiotherapy, or immunotherapy. The compounds of the invention can be administered alone or can be co-administered to the patient. Co- administration is meant to include simultaneous or sequential administration of the compounds individually or in combination (more than one compound). Thus, the

preparations can also be combined, when desired, with other active substances (e.g., to reduce metabolic degradation). The compositions of the present invention can be delivered by transdermally, by a topical route, formulated as applicator sticks, solutions, suspensions, emulsions, gels, creams, ointments, pastes, jellies, paints, powders, and aerosols. [0175] The compounds described herein can be used in combination with one another, with other active agents known to be useful in treating a disease associated with cells expressing a disease associated cellular component, or with adjunctive agents that may not be effective alone, but may contribute to the efficacy of the active agent. [0176] In some embodiments, co-administration includes administering one active agent within 0.5, 1, 2, 4, 6, 8, 10, 12, 16, 20, or 24 hours of a second active agent. Co- administration includes administering two active agents simultaneously, approximately simultaneously (e.g., within about 1, 5, 10, 15, 20, or 30 minutes of each other), or sequentially in any order. In some embodiments, co-administration can be accomplished by co-formulation, i.e., preparing a single pharmaceutical composition including both active agents. In other embodiments, the active agents can be formulated separately. In another embodiment, the active and/or adjunctive agents may be linked or conjugated to one another. [0177] As a non-limiting example, the compounds described herein can be co-administered with conventional chemotherapeutic agents including alkylating agents (e.g.,

cyclophosphamide, ifosfamide, chlorambucil, busulfan, melphalan, mechlorethamine, uramustine, thiotepa, nitrosoureas, etc.), anti-metabolites (e.g., 5-fluorouracil, azathioprine, methotrexate, leucovorin, capecitabine, cytarabine, floxuridine, fludarabine, gemcitabine, pemetrexed, raltitrexed, etc.), plant alkaloids (e.g., vincristine, vinblastine, vinorelbine, vindesine, podophyllotoxin, paclitaxel, docetaxel, etc.), topoisomerase inhibitors (e.g., irinotecan, topotecan, amsacrine, etoposide (VP16), etoposide phosphate, teniposide, etc.), antitumor antibiotics (e.g., doxorubicin, adriamycin, daunorubicin, epirubicin, actinomycin, bleomycin, mitomycin, mitoxantrone, plicamycin, etc.), platinum-based compounds (e.g., cisplatin, oxaloplatin, carboplatin, etc.), and the like. [0178] The compounds described herein can also be co-administered with conventional hormonal therapeutic agents including, but not limited to, steroids (e.g., dexamethasone), finasteride, aromatase inhibitors, tamoxifen, and gonadotropin-releasing hormone agonists (GnRH) such as goserelin. [0179] Additionally, the compounds described herein can be co-administered with conventional immunotherapeutic agents including, but not limited to, immunostimulants (e.g., Bacillus Calmette-Guérin (BCG), levamisole, interleukin-2, alpha-interferon, etc.), monoclonal antibodies (e.g., anti-CD20, anti-HER2, anti-CD52, anti-HLA-DR, and anti- VEGF monoclonal antibodies), immunotoxins (e.g., anti-CD33 monoclonal antibody- calicheamicin conjugate, anti-CD22 monoclonal antibody-pseudomonas exotoxin conjugate, etc.), and radioimmunotherapy (e.g., anti-CD20 monoclonal antibody conjugated to ¹¹¹ In, ⁹⁰ Y, or ¹³¹ I, etc.). [0180] In a further embodiment, the compounds described herein can be co-administered with conventional radiotherapeutic agents including, but not limited to, radionuclides such as ⁴⁷ Sc, ⁶⁴ Cu, ⁶⁷ Cu, ⁸⁹ Sr, ⁸⁶ Y, ⁸⁷ Y, ⁹⁰ Y, ¹⁰⁵ Rh, ¹¹¹ Ag, ¹¹¹ In, ^117m Sn, ¹⁴⁹ Pm, ¹⁵³ Sm, ¹⁶⁶ Ho, ¹⁷⁷ Lu, ¹⁸⁶ Re, ¹⁸⁸ Re, ²¹¹ At, and ²¹² Bi, optionally conjugated to antibodies directed against tumor antigens. [0181] In therapeutic use for the treatment of a disease, compound utilized in the pharmaceutical compositions of the present invention may be administered at the initial dosage of about 0.001 mg/kg to about 1000 mg/kg daily. A daily dose range of about 0.01 mg/kg to about 500 mg/kg, or about 0.1 mg/kg to about 200 mg/kg, or about 1 mg/kg to about 100 mg/kg, or about 10 mg/kg to about 50 mg/kg, can be used. The dosages, however, may be varied depending upon the requirements of the patient, the severity of the condition being treated, and the compound or drug being employed. For example, dosages can be empirically determined considering the type and stage of cancer diagnosed in a particular patient. The dose administered to a patient, in the context of the present invention, should be sufficient to affect a beneficial therapeutic response in the patient over time. The size of the dose will also be determined by the existence, nature, and extent of any adverse side-effects that accompany the administration of a compound in a particular patient. Determination of the proper dosage for a particular situation is within the skill of the practitioner. Generally, treatment is initiated with smaller dosages which are less than the optimum dose of the compound. Thereafter, the dosage is increased by small increments until the optimum effect under circumstances is reached. For convenience, the total daily dosage may be divided and administered in portions during the day, if desired. [0182] The compounds described herein can be used in combination with one another, with other active agents known to be useful in treating cancer, a neurodegenerative disease, a metabolic disease, an autoimmune disease, an inflammatory disease, or an infectious diease, or with adjunctive agents that may not be effective alone, but may contribute to the efficacy of the active agent. [0183] The term“associated” or“associated with” in the context of a substance or substance activity or function associated with a disease (e.g., a protein associated disease, disease associated with a cellular component) means that the disease (e.g., neurodegenerative disease, cancer) is caused by (in whole or in part), or a symptom of the disease is caused by (in whole or in part) the substance or substance activity or function or the disease or a symptom of the disease may be treated by modulating (e.g., inhibiting or activating) the substance (e.g., cellular component). For example, a neurodegenerative disease associated with a protein aggregate may be a neurodegenerative disease that results (entirely or partially) from aberrant protein aggregation or a neurodegenerative disease wherein a particular symptom of the disease is caused (entirely or partially) by aberrant protein aggregation. As used herein, what is described as being associated with a disease, if a causative agent, could be a target for treatment of the disease. For example, a neurodegenerative disease associated with aberrant protein aggregation or a protein aggregate associated neurodegenerative disease, may be treated with a protein aggregate modulator or protein aggregate targeted autophagy degrader, in the instance where increased protein aggregation causes the neurodegenerative disease. [0184] The term“aberrant” as used herein refers to different from normal. When used to describe enzymatic activity, aberrant refers to activity that is greater or less than a normal control or the average of normal non-diseased control samples. Aberrant activity may refer to an amount of activity that results in a disease, wherein returning the aberrant activity to a normal or non-disease-associated amount (e.g., by administering a compound or using a method as described herein), results in reduction of the disease or one or more disease symptoms. [0185] “Anti-cancer agent” is used in accordance with its plain ordinary meaning and refers to a composition (e.g., compound, drug, antagonist, inhibitor, modulator) having

antineoplastic properties or the ability to inhibit the growth or proliferation of cells. In some embodiments, an anti-cancer agent is a chemotherapeutic. In some embodiments, an anti- cancer agent is an agent identified herein having utility in methods of treating cancer. In some embodiments, an anti-cancer agent is an agent approved by the FDA or similar regulatory agency of a country other than the USA, for treating cancer. In embodiments, an anti-cancer agent is an agent with antineoplastic properties that has not (e.g., yet) been approved by the FDA or similar regulatory agency of a country other than the USA, for treating cancer.

A moiety of an anti-cancer agent is a monovalent anti-cancer agent (e.g., a monovalent form of an agent listed above). [0186] “Chemotherapeutic” or“chemotherapeutic agent” is used in accordance with its plain ordinary meaning and refers to a chemical composition or compound having antineoplastic properties or the ability to inhibit the growth or proliferation of cells. [0187] The term“electrophilic” as used herein refers to a chemical group that is capable of accepting electron density. An“electrophilic substituent,”“electrophilic chemical moiety,” or“electrophilic moiety” refers to an electron-poor chemical group, substituent, or moiety (monovalent chemical group), which may react with an electron-donating group, such as a nucleophile, by accepting an electron pair or electron density to form a bond. In some embodiments, the electrophilic substituent of the compound is capable of reacting with a cysteine residue. In some embodiments, the electrophilic substituent is capable of forming a covalent bond with a cysteine residue and may be referred to as a“covalent cysteine modifier moiety” or“covalent cysteine modifier substituent.” The covalent bond formed between the electrophilic substituent and the sulfhydryl group of the cysteine may be a reversible or irreversible bond. In some embodiments, the electrophilic substituent of the compound is capable of reacting with a lysine residue. In some embodiments, the electrophilic substituent of the compound is capable of reacting with a serine residue. In some embodiments, the electrophilic substituent of the compound is capable of reacting with a methionine residue. [0188] “Nucleophilic” as used herein refers to a chemical group that is capable of donating electron density. [0189] An amino acid residue in a protein“corresponds” to a given residue when it occupies the same essential structural position within the protein as the given residue.

Instead of a primary sequence alignment, a three dimensional structural alignment can also be used, e.g., where the structure of the selected protein is aligned for maximum correspondence with the human protein and the overall structures compared. In this case, an amino acid that occupies the same essential position as a specified amino acid in the structural model is said to correspond to the specified residue. [0190] The term“isolated,” when applied to a nucleic acid or protein, denotes that the nucleic acid or protein is essentially free of other cellular components with which it is associated in the natural state. It can be, for example, in a homogeneous state and may be in either a dry or aqueous solution. Purity and homogeneity are typically determined using analytical chemistry techniques such as polyacrylamide gel electrophoresis or high performance liquid chromatography. A protein that is the predominant species present in a preparation is substantially purified. [0191] The term“amino acid” refers to naturally occurring and synthetic amino acids, as well as amino acid analogs and amino acid mimetics that function in a manner similar to the naturally occurring amino acids. Naturally occurring amino acids are those encoded by the genetic code, as well as those amino acids that are later modified, e.g., hydroxyproline, g- carboxyglutamate, and O-phosphoserine. Amino acid analogs refers to compounds that have the same basic chemical structure as a naturally occurring amino acid, i.e., an a carbon that is bound to a hydrogen, a carboxyl group, an amino group, and an R group, e.g., homoserine, norleucine, methionine sulfoxide, methionine methyl sulfonium. Such analogs have modified R groups (e.g., norleucine) or modified peptide backbones, but retain the same basic chemical structure as a naturally occurring amino acid. Amino acid mimetics refers to chemical compounds that have a structure that is different from the general chemical structure of an amino acid, but that functions in a manner similar to a naturally occurring amino acid. The terms“non-naturally occurring amino acid” and“unnatural amino acid” refer to amino acid analogs, synthetic amino acids, and amino acid mimetics which are not found in nature. [0192] Amino acids may be referred to herein by either their commonly known three letter symbols or by the one-letter symbols recommended by the IUPAC-IUB Biochemical Nomenclature Commission. Nucleotides, likewise, may be referred to by their commonly accepted single-letter codes. [0193] The terms“polypeptide,”“peptide,” and“protein” are used interchangeably herein to refer to a polymer of amino acid residues, wherein the polymer may in embodiments be conjugated to a moiety that does not consist of amino acids. The terms apply to amino acid polymers in which one or more amino acid residue is an artificial chemical mimetic of a corresponding naturally occurring amino acid, as well as to naturally occurring amino acid polymers and non-naturally occurring amino acid polymers. [0194] An amino acid or nucleotide base“position” is denoted by a number that sequentially identifies each amino acid (or nucleotide base) in the reference sequence based on its position relative to the N-terminus (or 5'-end). Due to deletions, insertions, truncations, fusions, and the like that must be taken into account when determining an optimal alignment, in general the amino acid residue number in a test sequence determined by simply counting from the N-terminus will not necessarily be the same as the number of its corresponding position in the reference sequence. For example, in a case where a variant has a deletion relative to an aligned reference sequence, there will be no amino acid in the variant that corresponds to a position in the reference sequence at the site of deletion. Where there is an insertion in an aligned reference sequence, that insertion will not correspond to a numbered amino acid position in the reference sequence. In the case of truncations or fusions there can be stretches of amino acids in either the reference or aligned sequence that do not correspond to any amino acid in the corresponding sequence. [0195] The terms“numbered with reference to” or“corresponding to,” when used in the context of the numbering of a given amino acid or polynucleotide sequence, refers to the numbering of the residues of a specified reference sequence when the given amino acid or polynucleotide sequence is compared to the reference sequence. [0196] The term“protein complex” is used in accordance with its plain ordinary meaning and refers to a protein which is associated with an additional substance (e.g., another protein, protein subunit, or a compound). Protein complexes typically have defined quaternary structure. The association between the protein and the additional substance may be a covalent bond. In embodiments, the association between the protein and the additional substance (e.g., compound) is via non-covalent interactions. In embodiments, a protein complex refers to a group of two or more polypeptide chains. Proteins in a protein complex are linked by non-covalent protein–protein interactions. A non-limiting example of a protein complex is the proteasome. [0197] The term“protein aggregate” is used in accordance with its plain ordinary meaning and refers to an aberrant collection or accumulation of proteins (e.g., misfolded proteins). Protein aggregates are often associated with diseases (e.g., amyloidosis). Typically, when a protein misfolds as a result of a change in the amino acid sequence or a change in the native environment which disrupts normal non-covalent interactions, and the misfolded protein is not corrected or degraded, the unfolded/misfolded protein may aggregate. There are three main types of protein aggregates that may form: amorphous aggregates, oligomers, and amyloid fibrils. In embodiments, protein aggregates are termed aggresomes. In

embodiments, the protein aggregate is TDP43, HTT, APP, SNCA, or MAPT. In

embodiments, the protein aggregate includes the protein Beta amyloid, Amyloid precursor protein, IAPP, Alpha-synuclein, PrPSc, PrPSc, Huntingtin, Calcitonin, Atrial natriuretic factor, Apolipoprotein AI, Serum amyloid A, Medin, Prolactin, Transthyretin, Lysozyme, Beta-2 microglobulin, Gelsolin, Keratoepithelin, Beta amyloid, Cystatin, Immunoglobulin light chain AL, TDP43, or S-IBM. [0198] The term“vesicle” is used in accordance with its plain ordinary meaning and refers to a small membrane enclosed compartment within a cell. Vesicles are typically involved in transport, buoyancy control, or enzyme storage within a cell. Some vesicles, for example a lysosome, may include enzymes, proteins, polysaccharides, lipids, nucleic acids, or organelles within the compartment. Vesicles are typically formed within cells as a result of exocytosis or phagocytosis, however some vesicles are formed at the Golgi complex and transported to the cell membrane. Vesicles may be unilamellar or multilamellar. [0199] The term“small molecule” is used in accordance with its well understood meaning and refers to a low molecular weight organic compound that may regulate a biological process. In embodiments, the small molecule is a compound that weighs less than 900 daltons. In embodiments, the small molecule weighs less than 800 daltons. In embodiments, the small molecule weighs less than 700 daltons. In embodiments, the small molecule weighs less than 600 daltons. In embodiments, the small molecule weighs less than 500 daltons. In embodiments, the small molecule weighs less than 450 daltons. In embodiments, the small molecule weighs less than 400 daltons. [0200] The term“pseudokinase” is used in accordance with its well understood meaning in Biology and Chemistry and refers to proteins that are variants of kinases (e.g., having similar or identical protein structures or folds) that are catalytically deficient in kinase enzymatic activity. [0201] The term“GTPase” is used in accordance with its well understood meaning in Biology and Chemistry and refers to hydrolase enzymes capable of binding and hydrolyzing GTP. [0202] The term“histone modifying enzyme” is used in accordance with its well understood meaning in Biology and Chemistry and refers to proteins that are capable of modifying histones at one or more of various sites. In embodiments a histone modifying enzyme is an enzyme capable of acetylation, methylation, demethylation, phosphorylation, uqibuitination, sumoylation, ADP-ribosylation, deamination, and/or proline isomerization; all of one or more histone proteins. In embodiments, the histone modifying enzyme is a histone deacetylase, histone methyltransferase, or histone acetyltransferase. In embodiments, the histone modifying enzyme is SETD3. [0203] The terms“virus” or“virus particle” are used according to its plain ordinary meaning within Virology and refers to a virion including the viral genome (e.g., DNA, RNA, single strand, double strand), viral capsid and associated proteins, and in the case of enveloped viruses (e.g., herpesvirus), an envelope including lipids and optionally components of host cell membranes, and/or viral proteins. [0204] The term“viral disease” is an infection that occurs when an organisms’s body is invaded by pathogenic viruses and infectious virus particles attach to and enter susceptible cells. [0205] The term“kinase inhibitor” refers to an agent (e.g., small molecule, nucleic acid, protein, or antibody) that can reduce the activity or level of a kinase. [0206] The term“pseudokinase inhibitor” refers to an agent (e.g., small molecule, nucleic acid, protein, or antibody) that can reduce the activity or level of a pseudokinase. [0207] The term“GTPase inhibitor” refers to an agent (e.g., small molecule, nucleic acid, protein, or antibody) that can reduce the activity or level of a GTPase. [0208] The term“histone modifying enzyme inhibitor” refers to an agent (e.g., small molecule, nucleic acid, protein, or antibody) that can reduce the activity or level of a histone modifying enzyme. [0209] The term“monovalent anti-viral agent” refers to a monovalent form of an agent (e.g., small molecule, nucleic acid, protein, or antibody) that can reduce the activity or level of a virus (e.g., in a subject or patient). [0210] The term“mTOR” refers to the protein“mechanistic target of rapamycin

(serine/threonine kinase)” or“mammalian target of rapamycin.” The term“mTOR” may refer to the nucleotide sequence or protein sequence of human mTOR (e.g., Entrez 2475, Uniprot P42345, RefSeq NM_004958, or RefSeq NP_004949). The term“mTOR” includes both the wild-type form of the nucleotide sequences or proteins as well as any mutants thereof. In some embodiments,“mTOR” is wild-type mTOR. In some embodiments, “mTOR” is one or more mutant forms. The term“mTOR” XYZ refers to a nucleotide sequence or protein of a mutant mTOR wherein the Y numbered amino acid of mTOR that normally has an X amino acid in the wildtype, instead has a Z amino acid in the mutant. In embodiments, an mTOR is the human mTOR. In embodiments, the mTOR has the following amino acid sequence:

[0211] The term“mTORC1” refers to the protein complex including mTOR and Raptor (regulatory-associated protein of mTOR). mTORC1 may also include MLST8 (mammalian lethal with SEC13 protein 8), PRAS40, and/or DEPTOR. mTORC1 may function as a nutrient/energy/redox sensor and regulator of protein synthesis. The term“mTORC1 pathway” or“mTORC1 signal transduction pathway” refers to a cellular pathway including mTORC1. An mTORC1 pathway includes the pathway components upstream and downstream from mTORC1. An mTORC1 pathway is a signaling pathway that is modulated by modulation of mTORC1 activity. In embodiments, an mTORC1 pathway is a signaling pathway that is modulated by modulation of mTORC1 activity but not by modulation of mTORC2 activity. In embodiments, an mTORC1 pathway is a signaling pathway that is modulated to a greater extent by modulation of mTORC1 activity than by modulation of mTORC2 activity. [0212] The term“mTORC2” refers to the protein complex including mTOR and RICTOR (rapamycin-insensitive companion of mTOR). mTORC2 may also include GbL, mSIN1 (mammalian stress-activated protein kinase interacting protein 1), Protor 1/2, DEPTOR, TTI1, and/or TEL2. mTORC2 may regulate cellular metabolism and the cytoskeleton. The term“mTORC2 pathway” or“mTORC2 signal transduction pathway” refers to a cellular pathway including mTORC2. An mTORC2 pathway includes the pathway components upstream and downstream from mTORC2. An mTORC2 pathway is a signaling pathway that is modulated by modulation of mTORC2 activity. In embodiments, an mTORC2 pathway is a signaling pathway that is modulated by modulation of mTORC2 activity but not by modulation of mTORC1 activity. In embodiments, an mTORC2 pathway is a signaling pathway that is modulated to a greater extent by modulation of mTORC2 activity than by modulation of mTORC1 activity. [0213] The term“active site mTOR inhibitor” refers to a compound that inhibits the activity of mTOR (e.g., kinase activity) and binds to the the active site of mTOR (e.g., the ATP binding site, overlapping with the ATP binding site, blocking access by ATP to the ATP binding site of mTOR). Examples of active site mTOR inhibitors include, but are not limited to, INK128, PP242, PP121, MLN0128, AZD8055, AZD2014, NVP-BEZ235, BGT226, SF1126, Torin 1, Torin 2, WYE 687, WYE 687 salt (e.g., hydrochloride), PF04691502, PI- 103, CC-223, OSI-027, XL388, KU-0063794, GDC-0349, and PKI-587.

Example 1: Brain-specific inhibition of mTOR to mitigate systemic toxicity

[1218] We describe a novel method for inhibition of mTOR activity specific to the brain. mTOR is a protein kinase that plays a central role in regulating cell growth and proliferation, and is estimated to be overactivated in 30% of cancers. Therapeutic agents targeting mTOR have been widely pursued as potential therapies for cancer, as well as neurological disorders such as epilepsy. For example, a third-generation mTOR inhibitor, RapaLink-1, has been shown to be effacious in driving glioblastoma regression in animal models (1). However, the success of these therapies is often hampered by insufficient amount of drug that can cross the blood-brain barrier. Even when this condition is met, the application of these drugs is confounded by the toxicity caused by system-wide inhibition of mTOR (e.g.,

immunosuppression, hyperglycemia, mucocytis in particular is a class specific effect of all mTOR inhibitors). Our disclosure provides a distinct solution to this problem through the combination of 1) a brain-permeable mTOR inhibitor and 2) a brain-impermeable ligand of another protein, FKBP (referred to as“blocker” hereafter). This“binary pharmacology” is enabled by the unique mechanism of action of RapaLink-1 and rapamycin that they require an auxiliary protein, FKBP, to exert its function. It represents a novel therapeutic modality to focus the pharmacological effects of RapaLink-1/rapamycin in the brain while minimizing systemic exposure. [1219] Our invention is generally applicable in areas where brain-specific inhibition of mTOR can lead to a therapeutic advantage. A few examples include glioblastoma, epilepsy, tuberous sclerosis (TSC), and alcohol use disorders. [1220] Glioblastoma is a particularly deadly type of cancer with poor prognosis, with more than 10,000 diagnoses each year in the US alone. Glioblastoma tumors are difficult to remove surgically and lack effective treatment options. Our invention may be directly applied to develop a new drug for the treatment of glioblastoma with high efficacy and low toxicity. [1221] Epilepsy is the fourth most common neurological disorder– 2015 statistics from the CDC show 1.2% of the US population (3.4 million) have active epilepsy. Despite the abundance of drugs approved for epilepsy, most current drugs are anticonvulsants and work by suppressing seizures as symptomatic therapy but do not address the rooting cause. One- third of patients do not respond to these drugs and are defined as“medically intractable.” Treatment of epilepsy by mTOR inhibitors has shown promises as a new angle to tackle this disease. [1222] Tuberous Sclerosis (TSC) affects as many as 25,000 to 40,000 individuals in the United States and about 1 to 2 million individuals worldwide, with an estimated prevalence of one in 6,000 newborns (according to NIH). It is a genetic disease that causes benign tumor to grow in the brain and results in seizures, behavioral problems, developmental delay, etc. mTOR inhibitors directly address the mechanistic cause of the disease (overactive mTOR), and everolimus (a rapamycin analog) has been approved as treatment for this diease. Our invention can be similarly adopted in this disease area to provide a safe and effective TSC drug. [1223] Alcohol Use Disorder (AUD) affects approximately 15% of the world population and imposes significant medical and economical burdens. Recent research has shown the important role of mTOR signaling in the body's regulation of drinking behavior, and suggested pharmacological inhibition as a promising strategy to treat AUD. Our invention can be similarly adopted in this disease area to provide a safe and effective AUD drug. [1224] Table 1. mTOR inhibition is an attractive strategy for treating many brain-related diseases (e.g., glioblastoma, epilepsy, tuberous sclerosis, alcohol addiction), yet systemic mTOR inhibition is known to cause multiple toxic side effects (e.g., hyperglycemia, immune suppression mucositis).

[1225] Chronic mTOR inhibition and growth suppression in children. While mTOR inhibitors could be used in childhood diseases, this therapy has to be of limited duration, as chronic inhibition of mTOR is associated with growth failure (2,3). The fact that chronic use of mTOR inhibitors leads to short stature limits application of these agents in children who might need these agents chronically. Examples include children with tuberous sclerosis, neurofibromatosis, or similar disorders, where long-term delivery of mTOR inhibitors will likely increase IQ and behavior, but cannot be delivered chronically due to growth failure. Our ability to deliver mTOR inhibitors to the brain, while sparing exposure to the periphery, should allow use of these inhibitors chronically, in a broad range of developmental disorders in which chronic mTOR activation is associated with disease burden. [1226] Unlike traditional methods that improve brain drug uptake by modifying the drug itself (e.g., increasing hydrophobicity, synthesizing prodrugs), our approach features a new therapeutic modality by the combination of a known brain-permeable mTOR inhibitor (RapaLink-1/rapamycin) with a brain-impermeable compound with no therapeutic effects itself. In doing so, we not only increase the distribution of the drug in the brain, but also eliminate its undesired effects in peripheral tissues. In addition, there is no need to change the nature of the“active component”– rapamycin is an approved drug and all the previously characterized molecular mechanism of actions will continue to apply. [1227] Products developed with this technology will have augmented therapeutic effects in brain where the disease is but minimal systemic toxicity. Existing technologies (drugs) do not address this problem and system-wide mTOR inhibition is often associated with side effects. [1228] Use of a combination of a brain-targeted drug and non-brain permeable auxiliary drug is precedented, but not to inhibit mTOR (Table 2). [1229] Table 2. Known combinations of a blood-brain barrier (BBB)-permeable and a BBB-impermeable agent.

[1230] We have designed and synthesized several“blocker” molecules and shown that they can potently bind FKBP and thus render RapaLink-1 ineffective in cell culture. Four of these molecules have been tested in mice in combination with RapaLink-1; mice treated with these combination therapies showed augmented inhibition of mTOR in the brain (compared to RapaLink-1 alone) but no detectable change in mTOR signaling in peripheral tissues (skeletal muscle). Example 2: Building a focused, non-BBB permeable FKBP ligand library

[1231] A focused, non-BBB permeable FKBP ligand library was generated using the following workflow: (1) compound synthesis; (2) FKBP12 binding assay; (3) compound screen by western blot (S6-phosphorylation); and (4) in vivo brain/periphery distribution in mouse model.

Example 4: Bispecific chemical ligands allow programmable kinase inhibition

[1235] Dysregulation of kinase activity underlies a variety of human diseases. While many small molecule kinase inhibitors have demonstrated remarkable success in precision medicine, the temporal (timing) and spatial (tissue distribution) control of their activity remains an intractable challenge. Here we present a strategy to build a new class of kinase inhibitors that overcome these limitations. Created by chemically linking kinase inhibitors and the immunosuppressant FK506, the resultant bispecific ligands show kinase inhibitory activity that depends on the endogenous protein FKBP12 and hence can be modulated by co- administration with an exogenous FKBP12 ligand. Using this approach, we successfully constructed highly potent, cell-permeable, programmable inhibitors of Src-family kinases, HER2 and LRRK2 based on dasatinib, lapatinib and GNE-7915, respectively. The method described here may be adapted for other kinases and even other classes of therapeutic targets. [1236] Protein kinases orchestrate an intricate network of cellular signaling events, and their dysregulation are implicated in many human diseases including cancer, autoimmunity and neurodegenerative disorders. Inhibition of aberrant kinases by small molecule ligands proves to be a fruitful therapeutic strategy that remains widely pursued in various disease areas (48 FDA-approved kinase inhibitors as of December 2018). Nonetheless, methods are lacking to allow reversal of the effects of kinase inhibitors of or tissue-directed kinase inhibition. These features are highly desirable, as systemic kinase inhibition often is unnecessary and contributes to toxicity. Here we describe a method to construct bispecific chemical ligands that induce the association of protein kinases and a ubiquitously expressed protein, FKBP12, by chemically linking a kinase inhibitor to a high affinity ligand of FKBP, FK506. We show that these bispecific ligands are cell-permeable and effect potent, specific and long-lasting inhibition of their respective targets, and that their cellular activity is amenable to modulation with a separate ligand of FKBP12. We exemplify our approach with three case studies: an inhibitor of Src-family kinases based on dasatinib, an inhibitor of EGFR/HER2 based on lapatinib, and an inhibitor of LRRK2 based GNE7915. [1237] It is important to point out that several other FKBP12-binding hybrids have been reported with diverse pharmacological properties. For example, Briesewtiz et al. discovered that linking an pYEEI peptide to FK506 or SLF led to an increase or decrease of its affinity for the SH2 domain of Fyn in the presence of FKBP12, respectively. Gestwicki et al.

demonstrated that SLF-Congo Red is a bifunctional molecule that recruits FKBP12 to b- amyloids and uses the steric bulk of FKBP12 to inhibit b-amyloid aggregation. Marinec et al. reported that an amprenavir-SLF hybrid preferentially partitions into red blood cells which express high levels of FKBP12 protein, creating an intracellular reservoir of the HIV protease inhibitor and significantly increasing its serum half-life. Many properties observed with our bispecific kinase inhibitors are congruent with these precedents. However, a distinct advantage unique to our compounds is that their activity is highly dependent on the availability of FKBP12 protein; they are poor kinase inhibitors in the absence of FKBP12 and therefore their cellular activity can be conveniently modulated with another FKBP12 ligand (vide infra). [1238] We chose dasatinib, an FDA-approved pan-Src family kinase inhibitor, for our model study as abundant literature on its pharmacological properties and structural information is available to aid our initial design and analysis. Inspection of the crystal structures of FKBP12-FK506 complex (PDB: 1FKJ) and dasatinib-Src complex (PDB:

3G5D) revealed that the allyl group at the C21 position of FK506 and the hydroxylethyl group in dasatinib on the piperazine ring are exposed to solvent and serve as suitable sites for chemical fusing. Previous structure-activity relationship studies on FK506 and dasatinib also indicate that chemical alterations at these two sites have minimal impact on their affinities for their respective targets. We envisioned that modifying the C21 allyl group confers an additional advantage: substituents larger than allyl at this position will ablate FK506’s ability to inhibit its natural target calcineurin, an undesirable activity in our present application. To synthesize the bispecific ligand FK506-Dasatinib, we employed HATU-mediated amide coupling reaction to join a carboxylic acid derived from FK506 and a secondary amine derived from Dasatinib. The synthetic route used is amenable to incorporating linkers with various length and geometry for further optimization. [1239] Using a fluorescence polarization assay, we found that FK506-Dasatinib maintained potent binding to FKBP12 (K _d = 23 nM), consistent with our previous anticipation. To assess the kinase inhibition activity of FK506-Dasatinib, we performed in vitro kinase assays with ATP concentrations at the apparent Km values of each kinase. Three kinases were chosen in this preliminary investigation: Src, Csk and DDR2. Src and Csk are both Src-family tyrosine kinases but with opposite functions in cellular signal transduction, while DDR2 is a receptor tyrosine kinase also potently inhibited by dasatinib. Under standard assay conditions, FK506-Dasatinib showed weaker inhibitory activity toward all three kinases compared to dasatinib, with IC ₅₀ values more than ten-fold greater those of the latter (FIG.14B). To further mimic the cellular environment, we supplemented the assay buffer with 10 µM recombinant FKBP12, a concentration chosen to match the estimated intracellular concentration of FKBP proteins. At this FKBP concentration, we also ensured that >99.7% of the FK506-Dasatinib population would be in complex with FKBP12. Under the new assay conditions, we observed a significant left-shift of the inhibition curves for FK506-Dasatinib, whereas the potency of dasatinib remained unchanged. For Src and Csk, the two inhibitors achieved equipotent inhibition upon FKBP12 supplementation. Meanwhile, for DDR2, though enhancement of activity of FK506-Dasatinib was also observed, it was still inferior to dasatinib, failing to fully inhibit this kinase even at 1 µM concentration. This difference prompted us to investigate if linking FK506 to dasatinib had reshaped its selectivity for kinase targets. We profiled these two inhibitors against a panel of 485 protein kinases at 10 nM inhibitor concentration and with 10 µM supplemented FKBP12 protein (FIG.14C). Of these 485 kinases, 23 were inhibited >70% by both inhibitors, and another 11 were inhibited >70% by dasatinib but not FK506-Dasatinib. Overall, FK506-Dasatinib did not achieve greater inhibition of any kinase tested than dasatinib at 10 nM, but certain kinases (for example, DDR1) appeared to be more disfavored by FK506-Dasatinib than others. This differential attenuation of inhibitory activity may be attributed to the favorable or unfavorable interactions with FKBP12 that the kinase must experience in order to bind the FK506- Dasatinib/FKBP12 complex. In this model, we envision that when FKBP12 binds FK506- dasatinib, a composite surface is formed that presents the dasatinib moiety and surveys various proteins for energetically favorable binding events (FIG.14D). [1240] The participation of FKBP12 in the inhibition of kinases by FK506-dasatinib is further revealed by its ligand-dependent association with kinases. Addition of FK506- Dasatinib to a mixture of recombinant Src kinase domain (33 kDa) and FKBP12 (12 kDa) induced the formation of a stable complex (~50 kDa) that can be purified by size exclusion chromatography (FIG.15A). The molecular weight of the complex suggests a 1:1:1 stoichiometry consistent with the anticipated binding mechanism of FK506-dasatinib.

Differential scanning fluorimetry suggested that formation of this complex led to stabilization of both protein components toward thermal denaturation to a greater extent than dasatinib alone (FIG.15B). Such tripartite interactions are preserved in more complex native environments– Src co-immunoprecipitated with HA-FKBP12 in Jurkat cell lysates treated with FK506-Dasatinib, but not FK506 (FIG.15C). [1241] To evaluate the efficacy of FK506-Dasatinib in cells, we studied its effect on CD3 crosslinking-triggered T cell activation. Src family kinases, notably Lck and Fyn, are key regulators of T cell receptor (TCR) signal transduction, and dasatinib is known to block T cell activation by inhibiting these kinases. We stimulated Jurkat cells with an anti-CD3 monoclonal antibody (OKT3) in the presence of dasatinib or FK506-dasatinib and monitored their activation by Western blot. At 100 nM, both dasatinib and FK506-dasatinib dampened the of total phospho-tyrosine level and suppressed the phosphorylation of several proteins involved in TCR signaling including Src-family kinases, PLCgamma1, ZAP70 and LAT (FIG.16A). Interestingly, three homodimers of dasatinib containing linkers of various length (FIG.19A) had no measurable inhibition of phosphotyrosine signal. FK506-dasatinib was effective at concentrations as low as 10 nM (EC50 = 3.4 nM, FIG.16C). To profile the target scope of FK506-dasatinib in live cells, we employed a lysine-targeted chemoproteomic probe XO44, which irreversibly reacts with a conserved lysine in the ATP pocket of kinases and allows the quantification of the occupancy of the intracellular kinome by inhibitors by label- free mass spectrometry. We found that with both dasatinib and FK506-dasatinib at 100 nM, an identical set of 9 kinases were inhibited >70% (FIG.16B and FIG.20) among the 139 kinases captured by the probe. This is consistent with previous knowledge of dasatinib as well as our findings in the biochemical profiling with purified kinases. That the selectivity of FK506-dasatinib was indistinguishable from dasatinib was not surprising– none of kinases displaying differential response to the two inhibitors in the biochemical assay (FIG.14C) were highly expressed in Jurkat cells or detected by the XO44 probe. Notwithstanding, one remarkable distinction of FK506-dasatinib from dasatinib we observed was its prolonged residence time in cells. We measured the change of phosphotyrosine levels at various timepoints after treating Jurkat cells with 100 nM dasatinib or FK506-dasatinib for 1 h and removing the drug (FIG.16D). Restored phosphotyrosine bands were seen at as early as 1 h in dasatinib-treated cells. By contrast, no increase in phosphotyrosine signals could be detected even at 24 h after the drug washout in FK506-dasatinib-treated cells, suggesting a mechanism that supports durable cellular retention of the drug. Unusually long cellular retention times have also been previously observed with other drugs that engage FKBP proteins. We believe that in these cases, the abundant intracellular FKBP proteins serve as a sink for these drugs, capturing them as in a FKBP-drug complex that cannot cross the plasma membrane to exit the cell and hence significantly lengthening their residence inside the cell. [1242] The unique dependency of FK506-dasatinib on FKBP proteins implied that it may be exploited to modulate the function of these molecules. We reasoned that if FK506- dasatinib is co-administered with another ligand of FKBP (“blocker”), the latter would attenuate the activity FK506-dasatinib by competing for the intracellular pool of FKBP. We chose RapaBlock, a non-immunosuppressive FK506 analog developed in our lab that maintains potent binding to FKBP12 (Kd = 3.7 nM), as the blocker molecule. When a combination of 100 nM FK506-dasatinib and 10 µM RapaBlock were used in the Jurkat cell activation assay, the inhibition of phosphotyrosine signaling by FK506-dasatinib was completely neutralized (FIG.13A, lanes 3 and 6). Meanwhile, the blocker compound had no in dasatinib-treated samples (FIG.13A, lanes 2 and 5). In a separate application, we measured growth inhibition of K562 cells, a Bcr-Abl-driven cell lines sensitive to dasatinib treatment (FIG.13B). Absent ZZY05-026, dasatinib and FK506-dasatinib inhibited the growth of K562 cells with comparable potency (IC50 of 0.063 nM and 0.053 nM, respectively). Addition of 10 µM RapaBlock caused a >200-fold increase of the IC ₅₀ value for FK506-Dasatinib (10.2 nM), in contrast to the minute shift of IC ₅₀ for dasatinib (0.16 nM). [1243] We extended our design strategy and prepared two other bispecific ligands based on the structures of an FDA-approved HER2/EGFR inhibitor (lapatinib) and an LRRK2 inhibitor in clinical development (GNE7915). FK506-lapatinib suppressed HER2 signaling in SK-BR-3 cells (a cell line with HER2-amplification) at 1 µM and inhibited the growth of this cell line with an IC ₅₀ comparable to that of lapatinib (FIGS.17A-17C). Both effects were attenuated by the addition of 10 µM RapaBlock. Interestingly, FK506-GNE7915 appeared to be more efficacious than its parent molecule GNE7915 at inhibiting the autophosphorylation of LRRK2, a kinase currently pursued as a promising therapeutic target for Parkinson’s disease. Similar to the cases of FK506-dasatinib and FK506-lapatinib, RapaBlock rescued the inhibition of LRRK2 phosphorylation by FK506-GNE7915 to a near- baseline level. With the three case studies presented above, we anticipate that the same workflow could be applied to convert other kinase inhibitors into FKBP-dependent formats with similar if not better cellular activities, with the important recognition that exceptions may occur as in the case with FK506-Dasatinib/DDR2. [1244] By chemically linking FK506 and ATP-site kinase inhibitors at their respective solvent-exposed sites, we have developed a method to build a new class of kinase inhibitors whose activity depends on an endogenous protein, FKBP12. These inhibitors are

characterized by their ability to mediate the formation of a ternary complex of the drug, the target kinase and FKBP12, as well as their aptitude for activity modulation by another ligand of FKBP12. De novo complex formation has been exploited by nature as a strategy to create highly specific bioactive compounds, with notable examples including rapamycin (mTOR inhibitor), FK506 (calcineurin inhibitor), cyclosporin A (calcineurin inhibitor) and sanglifehrin (IMPDH2 inhibitor). Medicinal chemistry innovations have led to compounds with improved pharmaceutical property or efficacy (e.g., the third-generation mTOR inhibitor RapaLink-1), yet with the same target as the parent natural inhibitor. Our method expands the targetable space by this mode of action far beyond those addressed by known natural products. The amenability of these bispecific kinase inhibitors towards activity modulation by a second molecule is unique and offers an additional dimension of pharmacological control. In theory, timed administration of the blocker molecule or using blocker molecules that have defined tissue distribution will allow us to choreograph the temporal and spatial effects of the inhibitor and achieve programmable kinase inhibition. While we have focused on protein kinases in this study, it seems reasonable to expect that the approach is also applicable to other classes of therapeutic targets, such as GTPases and histone modification enzymes.

Example 6: Materials and methods

[1250] Note on rotamers in ¹ H NMR data. All of the SLF analogs and FK506 analogs synthesized here exist as a mixture of two amide rotamers in CDCl ₃ or CD ₃ OD. Due to extensive spectral overlap of the two, the coupling pattern of certain protons can be complicated even if they should display clear splitting patterns in theory. Sometimes, overlapping peaks prevent the identification of all peaks of the minor rotamer, and on occasion, of the major rotamer. In this document, only ¹ H NMR peaks of the major rotamer are reported in the best effort of resolving the peaks. [1251] Cyclosporin analogs demonstrate more complicated conformational flexibility. In CD3OD, most compounds exist as >6 conformational isomers (Ko, S. Y.; Dalvit, C. Int. J. Pept. Protein Res.1992, 40, 380–382.). In CDCl ₃ the spectra are generally less complicated, and for certain compounds, only two conformational isomers are observed. For these compounds the ¹ H NMR spectra in CDCl3 are resolvable, and peaks belonging to the major conformation are reported. [1252] Mini-workup. When a mini-workup (A/B) is indicated in the procedure, it was performed as follows: an aliquot (5 µL) of the reaction mixture was retrieved with a glass pipet and added to a plastic vial containing 0.2 mL organic solvent A and 0.2 mL aqueous solution B. The vial was shaken vigorously and allowed to stand until the two layers partitioned. The organic layer was then used for TLC or LC-MS analysis as specified in the procedure. [1253] Monitoring reaction progress by LC-MS. When analysis of the reaction mixture is indicated in the procedure, it was performed as follows. An aliquot (1 µL) of the reaction mixture (or the organic phase of a mini-workup mixture) was diluted with 100 µL 1:1 acetonitrile:water. 1 µL of the diluted solution was injected onto a Waters Acquity UPLC BEH C181.7 µm column and eluted with a linear gradient of 5–95% acetonitrile/water (+0.1% formic acid) over 3.0 min.

TLC plates were visualized by exposure to ultraviolet light (UV), then were stained by submersion in a 10% solution of phosphomolybdic acid (PMA) in ethanol or an acidic ethanolic solution of p-anisaldehyde (this solution was prepared by sequential additions of concentrated sulfuric acid (5.0 mL), glacial acetic acid (1.5 mL) and p- anisaldehyde (3.7 mL) to absolute ethanol (135 mL) at 23 °C with efficient stirring), followed by brief heating on a hot plate.

MCF7 cells were grown in 6-well tissue culture plates (2 plates total) to ~80% confluence (10% FBS in DMEM, 5% CO2, 37 ºC). Cells were treated with the following drug combinations with a fixed final DMSO concentration of 1%. The cells were incubated at 37 ºC for 4 h. The media was removed by aspiration and the cells were washed twice with ice-cold PBS (1 mL/well). Cells were scraped in the presence of 0.5 mL PBS/well, collected in microfuge vials and pelleted by centrifugation at 7,000 g for 1 min. The supernatant was removed by aspiration and the cell pellet was resuspended in 30 µL ice-cold RIPA Buffer supplemented with cOmplete protease inhibitors and PhosStop phosphotase inhibitors (Roche). Lysis was performed by incubating the suspension on ice for 10 min, and the resulting lysates were clarified by centrifugation at 14,000 g for 10 min. The clarified lysates were transferred into new microfuge tubes. Protein concentrations were determined with BCA assay and normalized to 2.0 mg/mL by dilution with RIPA buffer. Concentration-normalized lysates (30 µL/sample) were mixed with 7.5 µL 5x SDS Sample Buffer and boiled at 95 ºC for 5 min. Proteins were resolved by electrophoresis on a 4–12% Novex Bis-Tris gel (200 V, 35 min, MES Running Buffer) and the bands were transferred onto a 0.45 µM nitrocellulose membrane (75 V, 30 min). Western blot analysis was performed following the standard protocol with the antibodies in Table 11. [1433] Table 11. Antibodies used in Western blot analysis.

[1434] Primary antibodies were added as solutions in 5% BSA-TBST, and the membranes were incubated at 4 ºC overnight (16 h). The membranes were washed with TBST for three times (5 mL and 5 min for each wash). Secondary antibody binding was performed with LICOR IRDye 680RD Goat Anti-Mouse IgG or IRDye 800RD Goat Anti-Rabbit IgG in 5% non-fat milk-TBST (1:5000) at 23 ºC for 1 h.
