USP30 INHIBITORS AND USES THEREOF CROSS-REFERENCE TO RELATED APPLICATIONS [0001] The present application claims priority to United States provisional patent application serial number 62/898,820, filed September 11, 2019, and United States provisional patent application serial number 63/022,165, filed May 8, 2020, the entirety of each of which is incorporated herein by reference. TECHNICAL FIELD OF THE INVENTION [0002] The present invention relates to compounds and methods useful for inhibiting ubiquitin carboxyl-terminal hydrolase 30 (“USP30”), also known as deubiquitinating enzyme 30, ubiquitin thioesterase 30, or ubiquitin-specific-processing protease 30. The invention also provides pharmaceutically acceptable compositions comprising compounds of the present invention and methods of using said compositions in the treatment of various disorders. BACKGROUND OF THE INVENTION [0003] Parkinson’s disease (PD), an age-associated neurodegenerative disorder second only to Alzheimer’s disease (AD) in prevalence, affects nearly 1 million Americans with an estimated financial cost of $15 billion (Marras et al. Parkinson's Foundation PG: Prevalence of Parkinson's disease across North America. NPJ Parkinsons Dis 2018, 4:21. PMC6039505; Gooch et al. The burden of neurological disease in the United States: A summary report and call to action. Ann Neurol 2017, 81:479-484). Those numbers are anticipated to grow as the aged population world- wide increases. Although it is becoming increasingly evident that PD is a systemic disease involving a number of peripheral tissues as well as multiple brains regions and neuronal populations beyond dopaminergic neurons (Obeso et al. Past, present, and future of Parkinson's disease: A special essay on the 200th Anniversary of the Shaking Palsy. Mov Disord 2017, 32:1264-1310. PMC5685546.), existing treatments for PD primarily augment dopaminergic neurotransmission to provide symptomatic benefit. The efficacy of such treatments diminish with disease progression and intolerable motor complications emerge in a significant proportion of patients. Moreover, non-motor symptoms, including cognitive deficits reflecting non- dopaminergic pathology, remain a major source of disability. Given the strengths in the rigor of prior research implicating mitochondrial deficits in PD and AD, targeting the Parkin-USP30 pathway to restore mitochondrial homeostasis as a means of slowing disease progression holds great promise for the treatment of PD and AD. [0004] Convergent evidence – specifically, human pharmacology, genetics, and tissue pathology as well as animal model data – indicate that restoration of mitochondrial quality control, including induction of mitophagy (clearance of damaged mitochondria) and bioenergetics, holds the promise of slowing the progression of both PD (Park et al. Mitochondrial Dysfunction in Parkinson's Disease: New Mechanistic Insights and Therapeutic Perspectives. Curr Neurol Neurosci Rep 2018, 18:21. PMC5882770.) as well as AD (Fang et al. Mitophagy inhibits amyloid- beta and tau pathology and reverses cognitive deficits in models of Alzheimer's disease. Nat Neurosci 2019, 22:401-412.). The first evidence of mitochondrial dysfunction in PD emerged from the observation that exposure to the mitochondrial complex I inhibitor, 1-methyl-4-phenyl-1,2,3,4- tetrahydropyridine (MPTP), causes rapid parkinsonism and dopamine neuronal death (Langston et al. Chronic Parkinsonism in humans due to a product of meperidine-analog synthesis. Science 1983, 219:979-980.). Genetic studies of monogenic PD show that pathogenic mutations in genes encoding proteins participating in mitochondrial quality control, such as PINK1, PRKN, FBXO7, DJ-1, VPS13C, and CHCHD2 cause autosomal recessive, early onset parkinsonism (Canet-Aviles et al. The Parkinson's disease protein DJ-1 is neuroprotective due to cysteine-sulfinic acid-driven mitochondrial localization. Proc Natl Acad Sci U S A 2004, 101:9103-9108. PMC428480; Funayama et al. CHCHD2 mutations in autosomal dominant late-onset Parkinson's disease: a genome-wide linkage and sequencing study. Lancet Neurol 2015, 14:274-282; Burchell et al. The Parkinson's disease-linked proteins Fbxo7 and Parkin interact to mediate mitophagy. Nat Neurosci 2013, 16:1257-1265. PMC3827746; Lesage et al. French Parkinson's Disease Genetics S, International Parkinson's Disease Genomics C: Loss of VPS13C Function in Autosomal-Recessive Parkinsonism Causes Mitochondrial Dysfunction and Increases PINK1/Parkin-Dependent Mitophagy.

Mov Disord 2010, 25:1791-1800. PMC6005705.). Importantly, Genome- Wide Association (GWA) studies of sporadic PD show that mitochondrial-function-associated genes are risk factors for sporadic, late-onset PD (Billingsley et al. International Parkinson's Disease Genomics C, Ryten M, Koks S: Mitochondria function associated genes contribute to Parkinson's Disease risk and later age at onset. NPJ Parkinsons Dis 2019, 5:8. PMC6531455.). Moreover, a decrease in respiratory capacity of mitochondria has been shown in autopsied brain tissue from sporadic PD cases (Schapira et al. Mitochondrial complex I deficiency in Parkinson's disease. J Neurochem 1990, 54:823-827.). Recent evidence from peripheral blood cells of early/prodromal PD cases also demonstrates mitochondrial dysfunction (Smith et al. Mitochondrial dysfunction and increased glycolysis in prodromal and early Parkinson's blood cells. Mov Disord 2018, 33:1580-1590. PMC6221131.). Finally, mitochondrial complex 1 inhibitors such as MPTP or Rotenone cause retrograde degeneration of nigrostriatal dopamine neurons in animal models highlighting that these neurons with the most severe and prototypical degeneration in PD are particularly sensitive to mitochondrial dysfunction. [0005] Abnormal mitochondrial accumulation and mitophagy deficits have been observed in other age-related diseases such as AD and with aging itself (Fang et al.2019; Ridge and Kauwe, Mitochondria and Alzheimer's Disease: the Role of Mitochondrial Genetic Variation. Curr Genet Med Rep 2018, 6:1-10. PMC5842281.) . Recent work by Fang et al., demonstrates that mitophagy is reduced in the hippocampus of AD patients and that increased mitophagy is able to rescue cognitive impairment and prevent both Ab plaques and tau hyperphosphorylation in induced pluripotent stem cells (iPSC) and multiple animal models of AD (Fang et al. 2019). Positron Emission Tomography (PET) imaging of AD patients have suggested reduced oxidative phosphorylation and TCA cycle, while post-mortem analysis suggests a reduction in PGC1a, a transcriptional regulator of mitochondrial biogenesis and an essential part of the mitochondrial quality control cycle (Kapogiannis and Mattson, Disrupted energy metabolism and neuronal circuit dysfunction in cognitive impairment and Alzheimer's disease. Lancet Neurol 2011, 10:187-198. PMC3026092; Katsouri et al. PPARgamma-coactivator-1alpha gene transfer reduces neuronal loss and amyloid-beta generation by reducing beta-secretase in an Alzheimer's disease model. Proc Natl Acad Sci U S A 2016, 113:12292-12297. PMC5087021.). Transmission Electron Microscopy (TEM) analysis of mitochondrial structures in the hippocampus of post-mortem AD patients demonstrates abnormal mitochondrial morphology, altered mitophagy, and a reduction in parkin levels, which was exacerbated with disease progression (Ye et al., Parkin-mediated mitophagy in mutant hAPP neurons and Alzheimer's disease patient brains. Hum Mol Genet 2015, 24:2938- 2951. PMC4406302.). [0006] Modulating mitochondrial pathways, including increasing expression of Parkin or depletion of USP30, has been shown to be protective in a variety of genetic and toxin-based animal models of PD in multiple species ^2,20-27 (Bingol et al., The mitochondrial deubiquitinase USP30 opposes parkin-mediated mitophagy. Nature 2014, 510:370-375; Bian et al., Overexpression of parkin ameliorates dopaminergic neurodegeneration induced by 1- methyl-4-phenyl-1,2,3,6- tetrahydropyridine in mice. PLoS One 2012, 7:e39953.

PINK1/Parkin-dependent linear ubiquitination of proteins on the outer mitochondrial membrane (OMM) leads to removal of damaged protein and mitochondria through fission of mitochondrial derived vesicles (MDVs) or recruitment of phagophores to begin the mitophagy process. The deubiquitinating (DUB) enzyme, USP30, is present specifically on the OMM (unlike other DUBs such as USP8,15 and 35 implicated in mitochondrial quality control), and acts as a counterbalance to this process by specifically removing ubiquitin chains on parkin substrates. Involvement of USP30 in regulating mitophagy has been well established through functional genomic studies in mammalian, including human, cells and flies, further validating it as a promising target (Bingol et al., 2014). Without wishing to be bound by any particular theory, it is believed that USP30 inhibitors will promote the clearance of damaged mitochondria to restore mitochondrial homeostasis, attenuating the pathogenic cascade associated with PD pathogenesis.

[0026] The term “aryl” used alone or as part of a larger moiety as in “aralkyl,” “aralkoxy,” or “aryloxyalkyl,” refers to monocyclic or bicyclic ring systems having a total of five to fourteen ring members, wherein at least one ring in the system is aromatic and wherein each ring in the system contains 3 to 7 ring members. The term “aryl” may be used interchangeably with the term “aryl ring.” In certain embodiments of the present invention, “aryl” refers to an aromatic ring system which includes, but not limited to, phenyl, biphenyl, naphthyl, anthracyl and the like, which may bear one or more substituents. Also included within the scope of the term “aryl,” as it is used herein, is a group in which an aromatic ring is fused to one or more non–aromatic rings, such as indanyl, phthalimidyl, naphthimidyl, phenanthridinyl, or tetrahydronaphthyl, and the like. [0027] The terms “heteroaryl” and “heteroar–,” used alone or as part of a larger moiety, e.g., “heteroaralkyl,” or “heteroaralkoxy,” refer to groups having 5 to 10 ring atoms, preferably 5, 6, or 9 ring atoms; having 6, 10, or 14 ^ electrons shared in a cyclic array; and having, in addition to carbon atoms, from one to five heteroatoms.

A heteroaryl group may be mono– or bicyclic. The term “heteroaryl” may be used interchangeably with the terms “heteroaryl ring,” “heteroaryl group,” or “heteroaromatic,” any of which terms include rings that are optionally substituted. The term “heteroaralkyl” refers to an alkyl group substituted by a heteroaryl, wherein the alkyl and heteroaryl portions independently are optionally substituted. [0028] As used herein, the terms “heterocycle,” “heterocyclyl,” “heterocyclic radical,” and “heterocyclic ring” are used interchangeably and refer to a stable 5– to 7–membered monocyclic or 7–10–membered bicyclic heterocyclic moiety that is either saturated or partially unsaturated, and having, in addition to carbon atoms, one or more, preferably one to four, heteroatoms, as defined above. When used in reference to a ring atom of a heterocycle, the term "nitrogen" includes a substituted nitrogen. As an example, in a saturated or partially unsaturated ring having 0–3 heteroatoms selected from oxygen, sulfur or nitrogen, the nitrogen may be N (as in 3,4–dihydro– 2H–pyrrolyl), NH (as in pyrrolidinyl), or ⁺ NR (as in N–substituted pyrrolidinyl). [0029] A heterocyclic ring can be attached to its pendant group at any heteroatom or carbon atom that results in a stable structure and any of the ring atoms can be optionally substituted. Examples of such saturated or partially unsaturated heterocyclic radicals include, without limitation, tetrahydrofuranyl, tetrahydrothiophenyl pyrrolidinyl, piperidinyl, pyrrolinyl, tetrahydroquinolinyl, tetrahydroisoquinolinyl, decahydroquinolinyl, oxazolidinyl, piperazinyl, dioxanyl, dioxolanyl, diazepinyl, oxazepinyl, thiazepinyl, morpholinyl, 2-oxa-6- azaspiro[3.3]heptane, and quinuclidinyl. The terms “heterocycle,” “heterocyclyl,” “heterocyclyl ring,” “heterocyclic group,” “heterocyclic moiety,” and “heterocyclic radical,” are used interchangeably herein, and also include groups in which a heterocyclyl ring is fused to one or more aryl, heteroaryl, or cycloaliphatic rings, such as indolinyl, 3H–indolyl, chromanyl, phenanthridinyl, or tetrahydroquinolinyl. A heterocyclyl group may be mono– or bicyclic. The term “heterocyclylalkyl” refers to an alkyl group substituted by a heterocyclyl, wherein the alkyl and heterocyclyl portions independently are optionally substituted. [0030] As used herein, the term “partially unsaturated” refers to a ring moiety that includes at least one double or triple bond. The term “partially unsaturated” is intended to encompass rings having multiple sites of unsaturation, but is not intended to include aryl or heteroaryl moieties, as herein defined. [0031] As described herein, compounds of the invention may contain “optionally substituted” moieties. In general, the term “substituted,” whether preceded by the term “optionally” or not, means that one or more hydrogens of the designated moiety are replaced with a suitable substituent. Unless otherwise indicated, an “optionally substituted” group may have a suitable substituent at each substitutable position of the group, and when more than one position in any given structure may be substituted with more than one substituent selected from a specified group, the substituent may be either the same or different at every position. Combinations of substituents envisioned by this invention are preferably those that result in the formation of stable or chemically feasible compounds. The term “stable,” as used herein, refers to compounds that are not substantially altered when subjected to conditions to allow for their production, detection, and, in certain embodiments, their recovery, purification, and use for one or more of the purposes disclosed herein.

[0038] As used herein, the term "pharmaceutically acceptable salt" refers to those salts which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and lower animals without undue toxicity, irritation, allergic response and the like, and are commensurate with a reasonable benefit/risk ratio. Pharmaceutically acceptable salts are well known in the art. For example, S. M. Berge et al., describe pharmaceutically acceptable salts in detail in J. Pharmaceutical Sciences, 1977, 66, 1–19, incorporated herein by reference. Pharmaceutically acceptable salts of the compounds of this invention include those derived from suitable inorganic and organic acids and bases. Examples of pharmaceutically acceptable, nontoxic acid addition salts are salts of an amino group formed with inorganic acids such as hydrochloric acid, hydrobromic acid, phosphoric acid, sulfuric acid and perchloric acid or with organic acids such as acetic acid, oxalic acid, maleic acid, tartaric acid, citric acid, succinic acid or malonic acid or by using other methods used in the art such as ion exchange. Other pharmaceutically acceptable salts include adipate, alginate, ascorbate, aspartate, benzenesulfonate, benzoate, bisulfate, borate, butyrate, camphorate, camphorsulfonate, citrate, cyclopentanepropionate, digluconate, dodecylsulfate, ethanesulfonate, formate, fumarate, glucoheptonate, glycerophosphate, gluconate, hemisulfate, heptanoate, hexanoate, hydroiodide, 2– hydroxy–ethanesulfonate, lactobionate, lactate, laurate, lauryl sulfate, malate, maleate, malonate, methanesulfonate, 2–naphthalenesulfonate, nicotinate, nitrate, oleate, oxalate, palmitate, pamoate, pectinate, persulfate, 3–phenylpropionate, phosphate, pivalate, propionate, stearate, succinate, sulfate, tartrate, thiocyanate, p–toluenesulfonate, undecanoate, valerate salts, and the like. [0039] Salts derived from appropriate bases include alkali metal, alkaline earth metal, ammonium and N ⁺ (C _1–4 alkyl)4 salts. Representative alkali or alkaline earth metal salts include sodium, lithium, potassium, calcium, magnesium, and the like. Further pharmaceutically acceptable salts include, when appropriate, nontoxic ammonium, quaternary ammonium, and amine cations formed using counterions such as halide, hydroxide, carboxylate, sulfate, phosphate, nitrate, loweralkyl sulfonate and aryl sulfonate. [0040] Unless otherwise stated, structures depicted herein are also meant to include all isomeric (e.g., enantiomeric, diastereomeric, and geometric (or conformational)) forms of the structure; for example, the R and S configurations for each asymmetric center, Z and E double bond isomers, and Z and E conformational isomers. Therefore, single stereochemical isomers as well as enantiomeric, diastereomeric, and geometric (or conformational) mixtures of the present compounds are within the scope of the invention. Unless otherwise stated, all tautomeric forms of the compounds of the invention are within the scope of the invention. Additionally, unless otherwise stated, structures depicted herein are also meant to include compounds that differ only in the presence of one or more isotopically enriched atoms. For example, compounds having the present structures including the replacement of hydrogen by deuterium or tritium, or the replacement of a carbon by a ¹³ C- or ¹⁴ C-enriched carbon are within the scope of this invention. Such compounds are useful, for example, as analytical tools, as probes in biological assays, or as therapeutic agents in accordance with the present invention. In certain embodiments, a warhead moiety, R ¹ , of a provided compound comprises one or more deuterium atoms. In certain embodiments, Ring B of a provided compound may be substituted with one or more deuterium atoms. [0041] As used herein, the term “inhibitor” is defined as a compound that binds to and /or inhibits USP30 with measurable affinity. In certain embodiments, an inhibitor has an IC50 and/or binding constant of less than about 50 mM, less than about 1 mM, less than about 500 nM, less than about 100 nM, less than about 10 nM, or less than about 1 nM. [0042] A compound of the present invention may be tethered to a detectable moiety. It will be appreciated that such compounds are useful as imaging agents. One of ordinary skill in the art will recognize that a detectable moiety may be attached to a provided compound via a suitable substituent. As used herein, the term “suitable substituent” refers to a moiety that is capable of covalent attachment to a detectable moiety. Such moieties are well known to one of ordinary skill in the art and include groups containing, e.g., a carboxylate moiety, an amino moiety, a thiol moiety, or a hydroxyl moiety, to name but a few. It will be appreciated that such moieties may be directly attached to a provided compound or via a tethering group, such as a bivalent saturated or unsaturated hydrocarbon chain. In some embodiments, such moieties may be attached via click chemistry. In some embodiments, such moieties may be attached via a 1,3-cycloaddition of an azide with an alkyne, optionally in the presence of a copper catalyst. Methods of using click chemistry are known in the art and include those described by Rostovtsev et al., Angew. Chem. Int. Ed.2002, 41, 2596-99 and Sun et al., Bioconjugate Chem., 2006, 17, 52-57. [0043] As used herein, the term “detectable moiety” is used interchangeably with the term "label" and relates to any moiety capable of being detected, e.g., primary labels and secondary labels. Primary labels, such as radioisotopes (e.g., tritium, ³² P, ³³ P, ³⁵ S, or ¹⁴ C), mass-tags, and fluorescent labels are signal generating reporter groups which can be detected without further modifications. Detectable moieties also include luminescent and phosphorescent groups. [0044] The term “secondary label” as used herein refers to moieties such as biotin and various protein antigens that require the presence of a second intermediate for production of a detectable signal. For biotin, the secondary intermediate may include streptavidin-enzyme conjugates. For antigen labels, secondary intermediates may include antibody-enzyme conjugates. Some fluorescent groups act as secondary labels because they transfer energy to another group in the process of nonradiative fluorescent resonance energy transfer (FRET), and the second group produces the detected signal. [0045] The terms “fluorescent label”, “fluorescent dye”, and “fluorophore” as used herein refer to moieties that absorb light energy at a defined excitation wavelength and emit light energy at a different wavelength. Examples of fluorescent labels include, but are not limited to: Alexa Fluor dyes (Alexa Fluor 350, Alexa Fluor 488, Alexa Fluor 532, Alexa Fluor 546, Alexa Fluor 568, Alexa Fluor 594, Alexa Fluor 633, Alexa Fluor 660 and Alexa Fluor 680), AMCA, AMCA-S, BODIPY dyes (BODIPY FL, BODIPY R6G, BODIPY TMR, BODIPY TR, BODIPY 530/550, BODIPY 558/568, BODIPY 564/570, BODIPY 576/589, BODIPY 581/591, BODIPY 630/650, BODIPY 650/665), Carboxyrhodamine 6G, carboxy-X-rhodamine (ROX), Cascade Blue, Cascade Yellow, Coumarin 343, Cyanine dyes (Cy3, Cy5, Cy3.5, Cy5.5), Dansyl, Dapoxyl, Dialkylaminocoumarin, 4',5'-Dichloro-2',7'-dimethoxy-fluorescein, DM-NERF, Eosin, Erythrosin, Fluorescein, FAM, Hydroxycoumarin, IRDyes (IRD40, IRD 700, IRD 800), JOE, Lissamine rhodamine B, Marina Blue, Methoxycoumarin, Naphthofluorescein, Oregon Green 488, Oregon Green 500, Oregon Green 514, Pacific Blue, PyMPO, Pyrene, Rhodamine B, Rhodamine 6G, Rhodamine Green, Rhodamine Red, Rhodol Green, 2',4',5',7'-Tetra-bromosulfone- fluorescein, Tetramethyl-rhodamine (TMR), Carboxytetramethylrhodamine (TAMRA), Texas Red, Texas Red-X. [0046] The term “mass-tag” as used herein refers to any moiety that is capable of being uniquely detected by virtue of its mass using mass spectrometry (MS) detection techniques. Examples of mass-tags include electrophore release tags such as N-[3-[4’-[(p- Methoxytetrafluorobenzyl)oxy]phenyl]-3-methylglyceronyl]ison ipecotic Acid, 4’-[2,3,5,6- Tetrafluoro-4-(pentafluorophenoxyl)]methyl acetophenone, and their derivatives. The synthesis and utility of these mass-tags is described in United States Patents 4,650,750, 4,709,016, 5,360,8191, 5,516,931, 5,602,273, 5,604,104, 5,610,020, and 5,650,270. Other examples of mass- tags include, but are not limited to, nucleotides, dideoxynucleotides, oligonucleotides of varying length and base composition, oligopeptides, oligosaccharides, and other synthetic polymers of varying length and monomer composition. A large variety of organic molecules, both neutral and charged (biomolecules or synthetic compounds) of an appropriate mass range (100-2000 Daltons) may also be used as mass-tags. [0047] The terms “measurable affinity” and “measurably inhibit,” as used herein, means a measurable change in USP30 activity between a sample comprising a compound of the present invention, or composition thereof, and USP30, and an equivalent sample comprising USP30, in the absence of said compound, or composition thereof. 3.

The amount of a compound of the present invention in the composition will also depend upon the particular compound in the composition. Uses of Compounds and Pharmaceutically Acceptable Compositions [00178] Compounds and compositions described herein are generally useful for the inhibition of USP30. [00179] USP30, a deubiquitinase (DUB) localized to mitochondria and peroxisomes is an antagonist of Parkin- mediated mitophagy and of PEX2-mediated pexophagy. USP30, through its deubiquitinase activity, counteracts ubiquitination and degradation of damaged mitochondria, and inhibition of USP30 rescues mitophagy defects caused by mutant Parkin. Further, inhibition of USP30 decreases oxidative stress and provides protection against the mitochondrial toxin, rotenone. Since damaged mitochondria are more likely to accumulate Parkin, USP30 inhibition should preferentially clear unhealthy mitochondria. USP30 inhibition may beneficially increase rates of basal mitophagy, increase production of mitochondrial derived vesicles, arrest mitochondrial fission and trafficking, and generally improve mitochondrial quality control mechanisms. In addition to neurons (such as substantia nigra neurons, which are especially vulnerable to mitochondria dysfunction in Parkinson's disease), long-lived metabolically active cells such as cardiomyocytes also rely on an efficient mitochondria quality control system. In this context, Parkin has been shown to protect cardiomyocytes against ischemia/reperfusion injury through activating mitophagy and clearing damaged mitochondria in response to ischemic stress. Thus, inhibitors of USP30 are provided for use in treating a conditions involving mitochondrial defects, including neurological conditions, cardiac conditions, and systemic conditions. Deubiquinating enzymes function to oppose the action of the ubiquitinating enzymes in post- translational modification of cellular proteins. These conditions collectively represent examples of age related disorders and symptoms of natural aging suggesting further utility of USP30 inhibition to slow the process of aging and occurrence of age related disease. USP30 is a deubiquitinase that is localized to mitochondria and has been shown in expression studies to oppose the action of Parkin- mediated ubiquination and clearance of damaged mitochondria while also opposing basal ubiquitination by ligases such as MUL1 and MARCH5. USP30 that is localized to persoxisomes has been shown to oppose ubiquitination by PEX E3 ligases and induction of selective autophagy. [00180] In particular, disclosed herein are methods for modulating the activity of USP30 for the treatment of diseases, developmental delays, and symptoms related to mitochondrial dysfunction.

Prog Med Chem 2016, 55:149-192). USP8 can also deubiquitinate parkin, thus it may impact the mitophagy pathway. Furthermore, embryonic lethality resulting from USP8 knockout (Niendorf et al., Essential role of ubiquitin-specific protease 8 for receptor tyrosine kinase stability and endocytic trafficking in vivo. Mol Cell Biol 2007, 27:5029-5039. PMC1951504.) suggests USP8 inhibition may have detrimental toxicity. USP15 also localizes to mitochondria and can alter parkin-mediated mitophagy (Coyne and Wing, The business of deubiquitination - location, location, location. F1000Res 2016, 5. PMC4755399.). USP16 is similar to USP30 in that they both lack an aspartate as part of their catalytic triad (Gersch et al, Mechanism and regulation of the Lys6-selective deubiquitinase USP30. Nat Struct Mol Biol 2017, 24:920-930. PMC5757785; Nijman et al., A genomic and functional inventory of deubiquitinating enzymes. Cell 2005, 123:773-786; Mevissen and Komander, Mechanisms of Deubiquitinase Specificity and Regulation. Annu Rev Biochem 2017, 86:159-192.) and knockout of this gene is embryonic lethal. [00202] As used herein, the terms “treatment,” “treat,” and “treating” refer to reversing, alleviating, delaying the onset of, or inhibiting the progress of a disease or disorder, or one or more symptoms thereof, as described herein. In some embodiments, treatment may be administered after one or more symptoms have developed. In other embodiments, treatment may be administered in the absence of symptoms. For example, treatment may be administered to a susceptible individual prior to the onset of symptoms (e.g., in light of a history of symptoms and/or in light of genetic or other susceptibility factors). Treatment may also be continued after symptoms have resolved, for example to prevent or delay their recurrence. [00203] Provided compounds are inhibitors of USP30 and are therefore useful for treating one or more disorders associated with activity of USP30. Thus, in certain embodiments, the present invention provides a method for treating a USP30-mediated disorder comprising the step of administering to a patient in need thereof a compound of the present invention, or pharmaceutically acceptable composition thereof. [00204] As used herein, the term “USP30-mediated” disorders, diseases, and/or conditions as used herein means any disease or other deleterious condition in which USP30 is known to play a role. Accordingly, another embodiment of the present invention relates to treating or lessening the severity of one or more diseases in which USP30 is known to play a role. [00205] Furthermore, the invention provides the use of a compound according to the definitions herein, or a pharmaceutically acceptable salt, or a hydrate or solvate thereof for the preparation of a medicament for the treatment of a USP30-mediated disorder. Combination Therapies [00206] Depending upon the particular condition, or disease, to be treated, additional therapeutic agents, which are normally administered to treat that condition, may be administered in combination with compounds and compositions of this invention. As used herein, additional therapeutic agents that are normally administered to treat a particular disease, or condition, are known as “appropriate for the disease, or condition, being treated.” [00207] In certain embodiments, a provided combination, or composition thereof, is administered in combination with another therapeutic agent. [00208] Examples of agents the combinations of this invention may also be combined with include, without limitation: treatments for Alzheimer’s Disease such as Aricept ^® and Excelon ^® ; treatments for HIV such as ritonavir; treatments for Parkinson’s Disease such as L- DOPA/carbidopa, entacapone, ropinrole, pramipexole, bromocriptine, pergolide, trihexephendyl, and amantadine; agents for treating Multiple Sclerosis (MS) such as beta interferon (e.g., Avonex ^® and Rebif ^® ), Copaxone ^® , and mitoxantrone; treatments for asthma such as albuterol and Singulair ^® ; agents for treating schizophrenia such as zyprexa, risperdal, seroquel, and haloperidol; anti-inflammatory agents such as corticosteroids, TNF blockers, IL-1 RA, azathioprine, cyclophosphamide, and sulfasalazine; immunomodulatory and immunosuppressive agents such as cyclosporin, tacrolimus, rapamycin, mycophenolate mofetil, interferons, corticosteroids, cyclophophamide, azathioprine, and sulfasalazine; neurotrophic factors such as acetylcholinesterase inhibitors, MAO inhibitors, interferons, anti-convulsants, ion channel blockers, riluzole, and anti-Parkinsonian agents; agents for treating cardiovascular disease such as beta-blockers, ACE inhibitors, diuretics, nitrates, calcium channel blockers, and statins; agents for treating liver disease such as corticosteroids, cholestyramine, interferons, and anti-viral agents; agents for treating blood disorders such as corticosteroids, anti-leukemic agents, and growth factors; agents that prolong or improve pharmacokinetics such as cytochrome P450 inhibitors (i.e., inhibitors of metabolic breakdown) and CYP3A4 inhibitors (e.g., ketokenozole and ritonavir), and agents for treating immunodeficiency disorders such as gamma globulin. [00209] In certain embodiments, combination therapies of the present invention, or a pharmaceutically acceptable composition thereof, are administered in combination with a monoclonal antibody or an siRNA therapeutic. [00210] Those additional agents may be administered separately from a provided combination therapy, as part of a multiple dosage regimen. Alternatively, those agents may be part of a single dosage form, mixed together with a compound of this invention in a single composition. If administered as part of a multiple dosage regime, the two active agents may be submitted simultaneously, sequentially or within a period of time from one another normally within five hours from one another. [00211] As used herein, the term “combination,” “combined,” and related terms refers to the simultaneous or sequential administration of therapeutic agents in accordance with this invention. For example, a combination of the present invention may be administered with another therapeutic agent simultaneously or sequentially in separate unit dosage forms or together in a single unit dosage form. [00212] The amount of additional therapeutic agent present in the compositions of this invention will be no more than the amount that would normally be administered in a composition comprising that therapeutic agent as the only active agent. Preferably the amount of additional therapeutic agent in the presently disclosed compositions will range from about 50% to 100% of the amount normally present in a composition comprising that agent as the only therapeutically active agent. [00213] In one embodiment, the present invention provides a composition comprising a compound of formula I or formula I’ and one or more additional therapeutic agents.

[00231] The compounds and compositions, according to the method of the present invention, may be administered using any amount and any route of administration effective for treating or lessening the severity of an autoimmune disorder, an inflammatory disorder, a proliferative disorder, an endocrine disorder, a neurological disorder, or a disorder associated with transplantation. The exact amount required will vary from subject to subject, depending on the species, age, and general condition of the subject, the severity of the infection, the particular agent, its mode of administration, and the like. Compounds of the invention are preferably formulated in dosage unit form for ease of administration and uniformity of dosage. The expression "dosage unit form" as used herein refers to a physically discrete unit of agent appropriate for the patient to be treated. It will be understood, however, that the total daily usage of the compounds and compositions of the present invention will be decided by the attending physician within the scope of sound medical judgment. The specific effective dose level for any particular patient or organism will depend upon a variety of factors including the disorder being treated and the severity of the disorder; the activity of the specific compound employed; the specific composition employed; the age, body weight, general health, sex and diet of the patient; the time of administration, route of administration, and rate of excretion of the specific compound employed; the duration of the treatment; drugs used in combination or coincidental with the specific compound employed, and like factors well known in the medical arts. The term “patient”, as used herein, means an animal, preferably a mammal, and most preferably a human. [00232] Pharmaceutically acceptable compositions of this invention can be administered to humans and other animals orally, rectally, parenterally, intracisternally, intravaginally, intraperitoneally, topically (as by powders, ointments, or drops), bucally, as an oral or nasal spray, or the like, depending on the severity of the infection being treated. In certain embodiments, the compounds of the invention may be administered orally or parenterally at dosage levels of about 0.01 mg/kg to about 50 mg/kg and preferably from about 1 mg/kg to about 25 mg/kg, of subject body weight per day, one or more times a day, to obtain the desired therapeutic effect. [00233] Liquid dosage forms for oral administration include, but are not limited to, pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups and elixirs. In addition to the active compounds, the liquid dosage forms may contain inert diluents commonly used in the art such as, for example, water or other solvents, solubilizing agents and emulsifiers such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, dimethylformamide, oils (in particular, cottonseed, groundnut, corn, germ, olive, castor, and sesame oils), glycerol, tetrahydrofurfuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan, and mixtures thereof. Besides inert diluents, the oral compositions can also include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, and perfuming agents. [00234] Injectable preparations, for example, sterile injectable aqueous or oleaginous suspensions may be formulated according to the known art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution, suspension or emulsion in a nontoxic parenterally acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution, U.S.P. and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil can be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid are used in the preparation of injectables. [00235] Injectable formulations can be sterilized, for example, by filtration through a bacterial- retaining filter, or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable medium prior to use. [00236] In order to prolong the effect of a compound of the present invention, it is often desirable to slow the absorption of the compound from subcutaneous or intramuscular injection. This may be accomplished by the use of a liquid suspension of crystalline or amorphous material with poor water solubility. The rate of absorption of the compound then depends upon its rate of dissolution that, in turn, may depend upon crystal size and crystalline form. Alternatively, delayed absorption of a parenterally administered compound form is accomplished by dissolving or suspending the compound in an oil vehicle. Injectable depot forms are made by forming microencapsule matrices of the compound in biodegradable polymers such as polylactide- polyglycolide. Depending upon the ratio of compound to polymer and the nature of the particular polymer employed, the rate of compound release can be controlled. Examples of other biodegradable polymers include poly(orthoesters) and poly(anhydrides). Depot injectable formulations are also prepared by entrapping the compound in liposomes or microemulsions that are compatible with body tissues. [00237] Compositions for rectal or vaginal administration are preferably suppositories which can be prepared by mixing the compounds of this invention with suitable non-irritating excipients or carriers such as cocoa butter, polyethylene glycol or a suppository wax which are solid at ambient temperature but liquid at body temperature and therefore melt in the rectum or vaginal cavity and release the active compound. [00238] Solid dosage forms for oral administration include capsules, tablets, pills, powders, and granules. In such solid dosage forms, the active compound is mixed with at least one inert, pharmaceutically acceptable excipient or carrier such as sodium citrate or dicalcium phosphate and/or a) fillers or extenders such as starches, lactose, sucrose, glucose, mannitol, and silicic acid, b) binders such as, for example, carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidinone, sucrose, and acacia, c) humectants such as glycerol, d) disintegrating agents such as agar--agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate, e) solution retarding agents such as paraffin, f) absorption accelerators such as quaternary ammonium compounds, g) wetting agents such as, for example, cetyl alcohol and glycerol monostearate, h) absorbents such as kaolin and bentonite clay, and i) lubricants such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof. In the case of capsules, tablets and pills, the dosage form may also comprise buffering agents. [00239] Solid compositions of a similar type may also be employed as fillers in soft and hard- filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polyethylene glycols and the like. The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings and other coatings well known in the pharmaceutical formulating art. They may optionally contain opacifying agents and can also be of a composition that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner. Examples of embedding compositions that can be used include polymeric substances and waxes. Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polethylene glycols and the like. [00240] The active compounds can also be in micro-encapsulated form with one or more excipients as noted above. The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings, release controlling coatings and other coatings well known in the pharmaceutical formulating art. In such solid dosage forms the active compound may be admixed with at least one inert diluent such as sucrose, lactose or starch. Such dosage forms may also comprise, as is normal practice, additional substances other than inert diluents, e.g., tableting lubricants and other tableting aids such a magnesium stearate and microcrystalline cellulose. In the case of capsules, tablets and pills, the dosage forms may also comprise buffering agents. They may optionally contain opacifying agents and can also be of a composition that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner. Examples of embedding compositions that can be used include polymeric substances and waxes. [00241] Dosage forms for topical or transdermal administration of a compound of this invention include ointments, pastes, creams, lotions, gels, powders, solutions, sprays, inhalants or patches. The active component is admixed under sterile conditions with a pharmaceutically acceptable carrier and any needed preservatives or buffers as may be required. Ophthalmic formulation, ear drops, and eye drops are also contemplated as being within the scope of this invention. Additionally, the present invention contemplates the use of transdermal patches, which have the added advantage of providing controlled delivery of a compound to the body. Such dosage forms can be made by dissolving or dispensing the compound in the proper medium. Absorption enhancers can also be used to increase the flux of the compound across the skin. The rate can be controlled by either providing a rate controlling membrane or by dispersing the compound in a polymer matrix or gel.

[00300] As used herein, the term “combination,” “combined,” and related terms refers to the simultaneous or sequential administration of therapeutic agents in accordance with this invention. For example, a compound of the present invention may be administered with another therapeutic agent simultaneously or sequentially in separate unit dosage forms or together in a single unit dosage form. Accordingly, the present invention provides a single unit dosage form comprising a compound of the current invention, an additional therapeutic agent, and a pharmaceutically acceptable carrier, adjuvant, or vehicle. [00301] The amount of both an inventive compound and additional therapeutic agent (in those compositions which comprise an additional therapeutic agent as described above) that may be combined with the carrier materials to produce a single dosage form will vary depending upon the host treated and the particular mode of administration. Preferably, compositions of this invention should be formulated so that a dosage of between 0.01 - 100 mg/kg body weight/day of an inventive compound can be administered. [00302] In those compositions which comprise an additional therapeutic agent, that additional therapeutic agent and the compound of this invention may act synergistically. Therefore, the amount of additional therapeutic agent in such compositions will be less than that required in a monotherapy utilizing only that therapeutic agent. In such compositions a dosage of between 0.01 – 1,000 ^g/kg body weight/day of the additional therapeutic agent can be administered. [00303] The amount of additional therapeutic agent present in the compositions of this invention will be no more than the amount that would normally be administered in a composition comprising that therapeutic agent as the only active agent. Preferably the amount of additional therapeutic agent in the presently disclosed compositions will range from about 50% to 100% of the amount normally present in a composition comprising that agent as the only therapeutically active agent.
