BACKGROUND

[0003] Dysregulated behavior of cellular protein degradation by ubiquitin E3 ligases and the downstream proteasome system is an emerging theme in cancer. Currently, several inhibitors were developed to focus on the proteasome system and proven to be effective in treating several human cancers. However, few researchers have been focused on targeting upstream ubiquitin E3 ligases. Cullin-PJNG ubiquitin ligases (CRLs) comprise the largest known category of ubiquitin ligases. Among all E3 ligases, Cullin-based complex E3 ligase such as SCF (also known as Cull and Skpl-Cullin-F-box), has profound roles in regulating cell cycle progression, mitosis, and DNA repair, all link to cancer formation and progression. Interestingly, the activity of SCF complex is highly dependent on NEDD8 conjugation of the Cullin protein. So far, there is only one inhibitor, MLN4924, which targets the upstream pathway of Cullin Neddylation, thus disrupting SCF E3 ligase-mediated protein ubiquitination and leading to cell cycle arrest and tumor cell apoptosis. However, several other downstream proteins are also involved in Cullin Neddylation, and protein DCN1 is one of the essential components of the NEDD8 conjugation pathway. DCN1 specifically promotes Cullin Neddylation, and enhances the activity of all Cullin-based complex E3 ligases.

[0004] Protein ubiquitination is the major protein processing function in cells. Ubiquitin (Ub) flags a targeted protein for degradation through the 26s proteasome or lysosome. Tanaka et al., "c-Cbl-dependent monoubiquitination and lysosomal degradation of gpl30," Mol. Cell Biol, 25:4805-18 (2008). Ubiquitin is conjugated to a target protein in a three-step process. First, an El ubiquitin-activating enzyme binds to ubiquitin via a thioester covalent bond. Then, the El transfers the ubiquitin to an E2 ubiquitin-conjugating enzyme. Finally, the C-terminus of Ub is attached to the ε-amino lysine (K) residue of the substrate, mediated by an ubiquitin E3 ligase. There are several families of these ubiquitin E3 ligases that include over 1,000 proteins (Jin et al., "Dual El activation systems for ubiquitin differentially regulate E2 enzyme charging," Nature, 447: 1135-8 (2007), Hatakeyama et al., "U box proteins as a new family of ubiquitin- protein ligases," J. Biol. Chem., 276:33111-20 (2001)), of which the Skp-Cullin- F box (SCF) ubiquitin E3 ligase machinery are essential in regulating cell cycle progression, centrosome stability, and mitotic fidelity. Tyers et al., "One ring to rule a superfamily of E3 ubiquitin ligases," Science, 284:601, 3-4 (1999); Guardavaccaro et al., "Control of chromosome stability by the beta-TrCP-REST-Mad2 axis," Nature, 452:365-9 (2008); Seki et al., "Plkl- and beta- TrCP-dependent degradation of Bora controls mitotic progression," J. Cell Biol., 757:65-78 (2008); Gusti et al., "The Arabidopsis thaliana F-box protein FBL17 is essential for progression through the second mitosis during pollen development," PLoS One, :e4780 (2009);

D'Angiolella et al., "SCF(Cyclin F) controls centrosome homeostasis and mitotic fidelity through CP110 degradation," Nature, 466: 138-42 (2010). The SCF complex contains a catalytic core consisting of Skpl, Cullinl, and the E2 ubiquitin-conjugating (Ubc) enzyme and an F box component that acts as a receptor targeting numerous substrates via phosphodegron elicited interactions. Zheng et al., "Structure of the Cull-Rbxl-Skpl-F boxSkp2 SCF ubiquitin ligase complex," Nature, 416:103-9 (2002); Cardozo et al., "The SCF ubiquitin ligase: insights into a molecular machine," Nat. Rev. Mol. Cell Biol, 5:739-51 (2004); Cenciarelli et al.,

Biol., 9: 1177-9 (1999); Ilyin et al., "Identification of a novel Skp2-like mammalian protein containing F-box and leucine-rich repeats," FEBSLett., 459:15-9 (1999). Interestingly, SCF E3 ligase activity is heavily reliant upon Cullin protein modification by EDD8, a process essential to SCF function. Morimoto et al., "Nedd8-modification of Cull is promoted by Rocl as a Nedd8-E3 ligase and regulates its stability," Biochemical and biophysical research Commc 'ns, 301 :392-8 (2003); Amir et al., "The EDD8 pathway is essential for SCF(beta -TrCP)-mediated ubiquitination and processing of the F-kappa B precursor pl05," J. of biological chemistry, 277:23253-9 (2002); Wu et al., "Conjugation of Nedd8 to CUL1 enhances the ability of the ROC1-CUL1 complex to promote ubiquitin polymerization," J. of biological chemistry, 275:32317-24 (2000); Read et al., "Nedd8 modification of cul-1 activates SCF(beta(TrCP))-dependent ubiquitination of IkappaBalpha," Molecular and cellular biology, 20:2326-33 (2000). NEDD8 pathway is homologous to ubiquitination pathway since NEDD8 is an ubiquitin like protein (UBL). Soucy et al., "An inhibitor of NEDD 8 -activating enzyme as a new approach to treat cancer," Nature, 458:132-6 (2009). Similar to protein ubiquitination, Neddylation also occurs in a three step process.

NEDD8 is first activated by an El enzyme (NEDD8 activating enzyme, NAE), then transferred to an E2 enzyme (Ubcl2), before conjugated to target proteins. Id, Soucy et al. Since

Neddylation of Cullin protein is essential for SCF function, previous efforts were focused on targeting Cullinl Neddylation pathway as a new approach to treat cancer. So far, there is only one inhibitor, MLN4924, which targets the upstream pathway of Cullin Neddylation, the NAE protein, thus disrupting SCF E3 ligase-mediated protein ubiquitination and leading to cell cycle arrest and tumor cell apoptosis. However, several other downstream proteins are also involved in Cullin Neddylation, and specifically protein DCNl is one of the essential components of the NEDD8 conjugation pathway. DCNl functions by interacting with n-terminal of UBC12 E2 enzyme, which significantly facilitates and enhances NEDD8 conjugation to Cullin proteins. Thus DCNl promotes Cullin Neddylation, and enhances the activity of all Cullin based complex E3 ligases. DCNl protein overexpression promotes cellular growth, whereas DCNl protein knockdown drastically inhibits cell proliferation. Broderick et al., "SCCRO promotes glioma formation and malignant progression in mice," Neoplasia, 12:476-84 (2010); Fu et al.,

"Squamous Cell Carcinoma Related Oncogene (SCCRO) Family Members Regulate Cell Growth and Proliferation through Their Cooperative and Antagonistic Effects on Cullin

Neddylation," J. of Biol. Chem. (2016). DCNl protein is also called SCCRO (squamous cell carcinoma-related oncogene), and heavily overexpressed in many types of cancers, which makes it an ideal target for cancer drug development. Fu et al. (2016); Huang et al., "The ubiquitin- associated (UBA) domain of SCCRO/DCUN1D1 protein serves as a feedback regulator of biochemical and oncogenic activity," J. of Biol. Chem., 290:296-309 (2015).

[0005] There remains a need in the art for novel compounds and novel treatments to inhibit DCNl, which can greatly reduce Cullin Neddylation. There remains a need in the art for novel compounds and novel treatments to suppress the growth of human tumor cells. [0006] There remains a need in the art for novel compounds and novel treatments to provide anti-inflammatory activity in vitro or in vivo and in murine lung and colon inflammation. Since SCF activity is required for F-kB activation, DCN1 inhibitors exhibit excellent antiinflammatory activity in vitro and in murine lung and colon inflammation models.

[0007] The present invention satisfies these needs. DCN1 inhibitors as described herein, therefore, hold promise for the treatment of cancer and various inflammatory disorders.

V. Definitions

[0062] It is noted that, as used herein and in the appended claims, the singular forms "a", "an", and "the" include plural referents unless the context clearly dictates otherwise. It is further noted that the claims may be drafted to exclude any optional element. As such, this statement is intended to serve as antecedent basis for use of such exclusive terminology as "solely", "only" and the like in connection with the recitation of claim elements, or use of a "negative" limitation.

[0063] As used herein, the term "about" will be understood by persons of ordinary skill in the art and will vary to some extent depending upon the context in which it is used. If there are uses of the term which are not clear to persons of ordinary skill in the art given the context in which it is used, "about" will mean up to plus or minus 10% of the particular term.

[0064] Generally, reference to a certain element such as hydrogen or H is meant to include all isotopes of that element. For example, if an R group is defined to include hydrogen or H, it also includes deuterium and tritium. Hence, isotopically labeled compounds are within the scope of the invention.

[0065] In general, "substituted" refers to an organic group as defined below (e.g., an alkyl group) in which one or more bonds to a hydrogen atom contained therein are replaced by a bond to non-hydrogen or non-carbon atoms. Substituted groups also include groups in which one or more bonds to a carbon(s) or hydrogen(s) atom are replaced by one or more bonds, including double or triple bonds, to a heteroatom. Thus, a substituted group will be substituted with one or more substituents, unless otherwise specified. In some embodiments, a substituted group is substituted with 1, 2, 3, 4, 5, or 6 substituents. Examples of substituent groups include: halogens (i.e., F, CI, Br, and I); hydroxyls; alkoxy, alkenoxy, alkynoxy, aryloxy, aralkyloxy,

heterocyclyloxy, and heterocyclylalkoxy groups; carbonyls (oxo); carboxyls; esters; urethanes; oximes; hydroxylamines; alkoxyamines; aralkoxyamines; thiols; sulfides; sulfoxides; sulfones; sulfonyls; sulfonamides; amines; N-oxides; hydrazines; hydrazides; hydrazones; azides; amides; ureas; amidines; guanidines; enamines; imides; isocyanates; isothiocyanates; cyanates;

thiocyanates; imines; nitro groups; nitriles (i.e., CN); and the like. [0066] Substituted ring groups such as substituted cycloalkyl, aryl, heterocyclyl and heteroaryl groups also include rings and fused ring systems in which a bond to a hydrogen atom is replaced with a bond to a carbon atom. Therefore, substituted cycloalkyl, aryl, heterocyclyl and heteroaryl groups may also be substituted with substituted or unsubstituted alkyl, alkenyl, and alkynyl groups as defined below.

[0067] "Alkyl" groups include straight chain and branched alkyl groups having from 1 to about 20 carbon atoms, and typically from 1 to 12 carbons or, in some embodiments, from 1 to 8, 1 to 6, or 1 to 4 carbon atoms. Alkyl groups further include cycloalkyl groups as defined below. Examples of straight chain alkyl groups include those with from 1 to 8 carbon atoms such as methyl, ethyl, n-propyl, n-butyl, n-pentyl, n-hexyl, n-heptyl, and n-octyl groups. Examples of branched alkyl groups include, but are not limited to, isopropyl, iso-butyl, sec-butyl, tert-butyl, neopentyl, isopentyl, and 2,2-dimethylpropyl groups. Representative substituted alkyl groups may be substituted one or more times with substituents such as those listed above.

[0068] Cycloalkyl groups are cyclic alkyl groups such as, but not limited to, cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptyl, and cyclooctyl groups. In some embodiments, the cycloalkyl group has 3 to 8 ring members, whereas in other embodiments the number of ring carbon atoms range from 3 to 5, 3 to 6, or 3 to 7. Cycloalkyl groups further include mono-, bicyclic and polycyclic ring systems, such as, for example bridged cycloalkyl groups as described below, and fused rings, such as, but not limited to, decalinyl, and the like. In some embodiments, polycyclic cycloalkyl groups have three rings. Substituted cycloalkyl groups may be substituted one or more times with, non-hydrogen and non-carbon groups as defined above. However, substituted cycloalkyl groups also include rings that are substituted with straight or branched chain alkyl groups as defined above. Representative substituted cycloalkyl groups may be mono- substituted or substituted more than once, such as, but not limited to, 2,2-, 2,3-, 2,4- 2,5- or 2,6-disubstituted cyclohexyl groups, which may be substituted with substituents such as those listed above.

[0069] Bridged cycloalkyl groups are cycloalkyl groups in which two or more hydrogen atoms are replaced by an alkylene bridge, wherein the bridge can contain 2 to 6 carbon atoms if two hydrogen atoms are located on the same carbon atom, or 1 to 5 carbon atoms, if the two hydrogen atoms are located on adjacent carbon atoms, or 2 to 4 carbon atoms if the two hydrogen atoms are located on carbon atoms separated by 1 or 2 carbon atoms. Bridged cycloalkyl groups can be bicyclic, such as, for example bicyclo[2.1. ljhexane, or tricyclic, such as, for example, adamantyl. Representative bridged cycloalkyl groups include

In some embodiments, aryl groups contain 6-14 carbons, and in others from 6 to 12 or even 6-10 carbon atoms in the ring portions of the groups. Although the phrase "aryl groups" includes groups containing fused rings, such as fused aromatic-aliphatic ring systems (e.g., indanyl, tetrahydronaphthyl, and the like), it does not include aryl groups that have other groups, such as alkyl or halo groups, bonded to one of the ring members. Rather, groups such as tolyl are referred to as substituted aryl groups.

Representative substituted aryl groups may be mono-substituted or substituted more than once. For example, monosubstituted aryl groups include, but are not limited to, 2-, 3-, 4-, 5-, or 6- substituted phenyl or naphthyl groups, which may be substituted with substituents such as those listed above.

benzo[l,3]dioxolyl. The phrase also includes bridged polycyclic ring systems containing a heteroatom such as, but not limited to, quinuclidyl. However, the phrase does not include heterocyclyl groups that have other groups, such as alkyl, oxo or halo groups, bonded to one of the ring members. Rather, these are referred to as "substituted heterocyclyl groups".

Although the phrase "heteroaryl groups" includes fused ring compounds such as indolyl and 2,3-dihydro indolyl, the phrase does not include heteroaryl groups that have other groups bonded to one of the ring members, such as alkyl groups. Rather, heteroaryl groups with such substitution are referred to as "substituted heteroaryl groups." Representative substituted heteroaryl groups may be substituted one or more times with various substituents such as those listed above.

[0073] Groups described herein having two or more points of attachment (i.e., divalent, trivalent, or polyvalent) within the compound of the invention are designated by use of the suffix, "ene." For example, divalent alkyl groups are alkylene groups, divalent aryl groups are arylene groups, divalent heteroaryl groups are divalent heteroarylene groups, and so forth.

Substituted groups having a single point of attachment to the compound of the invention are not referred to using the "ene" designation. Thus, e.g., chloroethyl is not referred to herein as chloroethylene.

[0074] Alkoxy groups are hydroxyl groups (-OH) in which the bond to the hydrogen atom is replaced by a bond to a carbon atom of a substituted or unsubstituted alkyl group as defined above.

In some embodiments, the amine is H ₂ , methylamino, dimethylamino, ethylamino, diethylamino, propylamino, isopropylamino, phenylamino, or benzylamino. [0076] The term "amide" refers to a - R'R"C(0)- group wherein R and R each independently refer to a hydrogen, (Ci-C ₈ )alkyl, or (C3-C ₆ )aryl.

[0077] The term 'nitrile or cyano" can be used interchangeably and refer to a -CN group which is bound to a carbon atom of a heteroaryl ring, aryl ring and a heterocycloalkyl ring.

[0078] The substituent -C0 ₂ H, may be replaced with bioisosteric replacements such as:

and the like, wherein R has the same definition as R' and R" as defined herein. See, e.g., THE PRACTICE OF MEDICINAL CHEMISTRY (Academic Press: New York, 1996), at page 203.

[0079] Those of skill in the art will appreciate that compounds of the invention may exhibit the phenomena of tautomerism, conformational isomerism, geometric isomerism and/or optical isomerism.

[0080] "Tautomers" refers to isomeric forms of a compound that are in equilibrium with each other. The concentrations of the isomeric forms will depend on the environment the compound is found in and may be different depending upon, for example, whether the compound is a solid or is in an organic or aqueous solution. For example, in aqueous solution, pyrazoles may exhibit the following isomeric forms, which are referred to as tautomers of each other:

[0081] As readily understood by one skilled in the art, a wide variety of functional groups and other structures may exhibit tautomerism, and all tautomers of compounds as described herein are within the scope of the present invention.

[0082] Stereoisomers of compounds, also known as "optical isomers," include all chiral, diastereomeric, and racemic forms of a structure, unless the specific stereochemistry is expressly indicated. Thus, compounds used in the present invention include enriched or resolved optical isomers at any or all asymmetric atoms as are apparent from the depictions. Both racemic and diastereomeric mixtures, as well as the individual optical isomers can be isolated or synthesized so as to be substantially free of their enantiomeric or diastereomeric partners, and these are all within the scope of the invention.

[0083] By "pharmaceutically acceptable" is meant a material that is not biologically or otherwise undesirable, i.e., the material may be incorporated into a pharmaceutical composition administered to a patient without causing any undesirable biological effects or interacting in a deleterious manner with any of the other components of the composition in which it is contained. When the term "pharmaceutically acceptable" is used to refer to a pharmaceutical carrier or excipient, it is implied that the carrier or excipient has met the required standards of toxicological and manufacturing testing or that it is included on the Inactive Ingredient Guide prepared by the U.S. and Drug administration.

[0084] By "patient" is meant any animal for which treatment is desirable. Patients may be mammals, and typically, as used herein, a patient is a human individual.

Examples of acids which can be employed to form pharmaceutically acceptable addition salts include inorganic acids such as hydrochloric, hydrobromic, sulfuric, and phosphoric, and organic acids such as oxalic, maleic, succinic, and citric. Salts can also be formed by coordination of the compounds with an alkali metal or alkaline earth ion. Hence, the present invention contemplates sodium, potassium, magnesium, and calcium salts of the compounds of the compounds of the present invention and the like.

[0086] The term "solvates" is used in its broadest sense. For example, the term solvates includes hydrates formed when a compound of the present invention contains one or more bound water molecules.

VI. Working Examples

[0093] The present technology is further illustrated by the following examples, which should not be construed as limiting in any way.

General information.

[0094] All non-aqueous reactions were carried out under a nitrogen atmosphere in oven- or flame-dried glassware unless otherwise noted. Anhydrous tetrahydrofuran and diethyl ether were distilled from sodium benzophenone ketyl; anhydrous dichloromethane and toluene were distilled from CaH ₂ ; alternatively, the same solvents were obtained from a solvent purification system using alumina columns. All other solvents and reagents were used as obtained from commercial sources without further purification unless noted. Reactions were monitored via TLC using 250 μπι pre-coated silica gel 60 F ₂₅₄ plates, which were visualized with 254 nm and/or 365 nm UV light and by staining with KMn0 ₄ (1.5 g KMn0 ₄ , 10 g K ₂ C0 ₃ , and 1.25 mL 10% NaOH in 200 mL water), cerium molybdate (0.5 g Ce( H ₄ ) ₂ (N0 ₃ ) ₆ , 12 g

( Η ₄ ) ₆ Μθ ₇ θ ₂₄ ·4Η ₂ 0, and 28 mL cone. H ₂ S0 ₄ in 235 mL water), or vanillin (6 g vanillin and 1.5 mL cone. H ₂ S0 ₄ in 100 mL EtOH). Flash chromatography was performed with SiliCycle silica gel 60 (230-400 mesh) or with ISCO MPLC. 1H and ¹³ C MR spectra were recorded on Bruker Avance 300, 400, or 500 MHz spectrometers, using the residual solvent as an internal standard. IR spectra were obtained on a Smiths Identify IR or PerkinElmer Spectrum 100. HRMS data were obtained on a Thermo Scientific Exactive HRMS coupled to a Thermo Scientific Accela HPLC system using a 2.1 x 50 mm 3.5 μπι Waters XTerra Ci ₈ column eluting with MeCN/H ₂ 0 containing 0.1% formic acid. Purity of compounds was assessed using the same HPLC system with either the PDA or an Agilent 385 ELSD. All final screening samples passed QC based on >95% purity by LC/MS/ELSD analysis.

General Synthetic Scheme

Generally, equimolar amounts (e.g., 5 mmol) of amine variant and cyclohexane-l,3-dione variant were added to a suitable solvent (e.g., 30 ml ethyl acetate). The solution was stirred and refluxed for, e.g., 30 min. Progression of the reaction was monitored by techniques known in the art. The reaction mixture was cooled in an ice bath, and the resulting product was precipitated, filtered, and dried to provide the desired products. Products can be further purified by crystallization or column chromatography, as is customary in the art.

Example 1

[0095] 5mmol of Decylamine and 5mmol of 5-Phenylcyclohexane-l,3-dione were added to 30ml ethyl acetate. The solution was stirred and refluxed for 30min. The reaction mixture was cooled in an ice bath, and the resulting product was precipitated, filtered, dried to desired products as yellow powder (0.95 g, 55% yield).

[0096] Additional compounds were synthesized, and are shown in Table 3. Example 2

[0097] 4KHepG2 cells were seeded in 96 well plates for overnight. Compounds listed in Table 3 were then added to each well at various concentrations. 96h later, cell proliferation was measured by ATP production using a CellTiter-Glo® Luminescent Cell Viability Assay (Promega . IC50p _ro ii _feration for each compound was determined (n=3), and is shown in Table 3.

*"+" >10μΜ, "++" >1μΜ and <10μΜ, "+++"< Ι μΜ. Example 3

[0098] DCN1 protein is believed to harbor a UBC12 binding pocket. Scott et al, Cell, 757: 1671-84 (2014). The structure of a RING E3 trapped in action reveals that ligation mechanism for the ubiquitin-like protein NEDD8. Scott et al. (2014). The N-terminal acetylation acts as an avidity enhancer within an interconnected multiprotein complex. Science, 334:614- (2011). Specifically, n-terminal of UBC12 is acetylated (Fig. 1A, yellow) and completely buried inside the hydrophobic pocket within DCN1 (4gao.PDB, Fig. IB). Small molecule inhibition of the DCN1 hydrophobic pocket would presumably disrupt UBC12 binding, and thus disrupt Neddylation of Cullin protein. Potential ligands were assessed that might fit the DCN1 domain cavities (Fig. IB). 3-(pentylamino)-5-phenylcyclohex-2-en-l-one was selected for future testing (Fig. 1C). Fig ID shows the in silico docking model 3-(pentylamino)-5-phenylcyclohex-2-en-l- one (Green) bound to DCN1. 3-(pentylamino)-5-phenylcyclohex-2-en-l-one showed good activity towards reducing cullinl neddylation (Fig. 2). MLN4924 was used as a positive control.

[0099] 3-(pentylamino)-5-phenylcyclohex-2-en-l-one was modified by adding a different sidechain. These novel compounds were tested further in an in vitro proliferation assay using ATPLite Cell Proliferation kit. The compound structures and their IC50 _pro iif _er a _t ion are listed in Table 3. Certain compounds showed significant improvement in their activity (Fig. 3A-B). Others lost activity in reducing Cullin Neddylation and inhibiting cell proliferation (Fig. 3C-D). 3-(decylamino)-5-phenylcyclohex-2-en-l-one which harbors CIO alkyl sidechain exhibited activity in reducing Cullin Neddylation and inhibiting cell proliferation (Fig. 3C-D).

[0100] 3-(decylamino)-5-phenylcyclohex-2-en-l-one was tested and compared with MLN4924 and showed comparable activity. 5-(l,3-benzodioxol-5-yl)-3-(decylamino)cyclohex-2-en-l-one was used as a negative control (Fig. 4A-B).

[0101] 3-(decylamino)-5-phenylcyclohex-2-en-l-one was further tested in HepG2 cells in a dose dependent manner. As shown in Fig. 5A, BC1558 drastically reduced neddylation of several cullin isoforms. 3-(decylamino)-5-phenylcyclohex-2-en-l-one also effectively increased apoptosis markers Clvd-caspase3 and Clvd-PARP (Fig 5A). 3-(decylamino)-5-phenylcyclohex- 2-en-l-one also effectively decreased S phase, and increased GO and G2/M phases in a dose dependent manner (Fig. 5B). Finally, 3-(decylamino)-5-phenylcyclohex-2-en-l-one was tested in a wound-healing assay and showed inhibition in hepG2 cells migration (Fig. 5C).

[0102] 3-(decylamino)-5-phenylcyclohex-2-en-l-one was tested in HepG2 cells in a time dependent manner. As shown in Fig. 6A, 3-(decylamino)-5-phenylcyclohex-2-en-l-one drastically reduced neddylation of several cullin isoforms, but increased SCF substrates p27, NRF2 and CDT1. 3-(decylamino)-5-phenylcyclohex-2-en-l-one also effectively increased apoptosis markers Clvd-caspase3 and Clvd-PARP. At 16h, 3-(decylamino)-5-phenylcyclohex-2- en- 1 -one also effectively decreased S phase, increased GO and G2/M phases (Fig. 6B). Finally, 3-(decylamino)-5-phenylcyclohex-2-en-l-one treatment also resulted in accumulation of rounded, apoptotic hepG2 cells in a time dependent manner (Fig. 6C).

[0103] The integrity of the centrosome and mitotic spindles after 3-(decylamino)-5- phenylcyclohex-2-en-l-one treatment was examined. HepG2 cells were stained with antibody to a-tubulin to visualize the mitotic spindle (Fig 7A-B). Abnormal cells with several representative mitotic abnormalities were also detected after 3-(decylamino)-5-phenylcyclohex-2-en-l-one treatment (Fig. 7B). The circular prophase configurations were observed (Fig. 7B, top panel). One classic phenotype of the circular chromosome configuration is circular figures arranged on monopolar spindles around large centrosomes. No spindles assembly in metaphase was observed (Fig. 7B, lower panel).

[0104] As a complementary in vivo model, tumor ogeni city was further assessed after implanting HepG2 cells along with 3-(decylamino)-5-phenylcyclohex-2-en-l-one, 3- (dibenzylamino)-5-phenylcyclohex-2-en-l-one, 3-((4-phenoxybenzyl)amino)-5-phenylcyclohex-

2- en-l-one treatment in athymic nude mice. Mice were implanted with HepG2 cells through subcutaneous injection. Two weeks later, once tumor size reached ~0.1 cm ³ , the mice were randomized and the treatment began by adding compounds to the drinking water (15 mg/kg/d). Significantly reduced tumor size was observed with all compounds treatment compared to the vehicle (Fig. 8).

[0105] A PD/PK study was also performed. Mice were implanted with HepG2 cells (10 ⁶ cells) through subcutaneous injection. 5 weeks later, once tumor size reached -0.3 cm ³ , mice were randomized and given 1 dose of 3-(decylamino)-5-phenylcyclohex-2-en-l-one (15 mg/kg) by oral gavage (Fig. 9A). Protein immunoblotting was performed and showed that a single dose of

3- (decylamino)-5-phenylcyclohex-2-en-l-one resulted in a time-dependent decrease of NEDD8- cullin levels within lh after administration of compound with maximal effect 2-4 h post-dose (Fig. 9B). A single dose of 3-(decylamino)-5-phenylcyclohex-2-en-l-one also led to a time- dependent increase in the steady state levels of NRF2 and CDT1. NRF2 protein levels peaked 4 h after administration of BC1558 and started to decline by 8-24 h post-dose. The timing of CDT1 accumulation was compared to NRF2, peaking 4 h after 3-(decylamino)-5-phenylcyclohex-2-en- 1-one administration. Evidence of DNA damage in the tumor was indicated by the increased levels of phosphorylated CHK1 (Ser 317) at 8 h after a single administration of 3-(decylamino)- 5-phenylcyclohex-2-en-l-one.

[0106] Since SCF machinery is believed to be essential for F-kB activation, it was investigated whether the DCN1 inhibitors could affect inflammation. 3-(decylamino)-5- phenylcyclohex-2-en-l-one was first tested in PBMCs cells. Briefly, PBMC cells were treated with 3-(decylamino)-5-phenylcyclohex-2-en-l-one at various concentrations for 2h before exposed to LPS (lOng/ml) for 12h. It was observed that 3-(decylamino)-5-phenylcyclohex-2-en- 1-one potently inhibited LPS-induced TNF release from PBMC cells (Fig. 10A).

[0107] 3-(decylamino)-5-phenylcyclohex-2-en-l-one was next tested in human lung tissue. Human lung slices were pretreated with 3-(decylamino)-5-phenylcyclohex-2-en-l-one for 18h before LPS treatment (lOOng/ml) for additional 4h. It was observed that 3-(decylamino)-5- phenylcyclohex-2-en-l-one potently inhibited LPS induced ILl, IL6 and TNF release from lung tissue. 3-(decylamino)-5-phenylcyclohex-2-en-l-one reduced nedd8-cullins level and rescued ΙκΒα in a dose dependent manner.

[0108] To assess in vivo anti-inflammatory activity of these compounds, they were tested using P. aeruginosa-m ^' duced pneumonia models. Briefly, C57BL/6J mice were administered i.t. with PA103 (1.5* 104CFU/mouse). Compounds were given through i.p. injection (30mg/kg) at the same time. 18 h later mice were euthanized, and the lungs were lavaged with saline. DCN1 inhibitors significantly decreased lavage protein concentration and lavage cell counts in PA103 (Fig. 11A-B) stimulated mice. DCN1 inhibitors also significantly reduced lavage cytokine ILl and IL6 (Fig. 11C-D).

[0109] Also tested were 3-(decylamino)-5-phenylcyclohex-2-en-l-one (BC1558), 3- (dibenzylamino)-5-phenylcyclohex-2-en-l-one (BC1634) and 3-((4-phenoxybenzyl)amino)-5- phenylcyclohex-2-en-l-one (BC1653) in a mouse colitis model to confirm its anti-inflammatory activity. Briefly, C57BL6 mice were fed with water containing 3.5% ice were euthanized and colonic length was measured. DSS produced a significant decrease in colon length in mice, consistent with colonic inflammation (Fig. 12A-B). However, mice treated with DCN1 inhibitor showed significant increase in colon length compared vehicle. Colonic tissue cytokine levels were further analyzed. As shown in Fig. 12C-D, mice treated with DCN1 inhibitor showed a large reduction in ILl β and IL6 levels in colonic tissue compared to vehicle treated mice. VII. Additional Embodiments
