Description

INHIBITORS OF NEDDS-ACTIVATING ENZYME FIELD This invention relates to compounds, compositions and methods for the treatment of various disorders, particularly disorders of cell proliferation, including cancers, and inflammatory disorders. in particular, the invention provides nds which inhibit the activity of NEDD8— activating enzyme.

BACKGROUND The post-translational modification of proteins by ubiquitin-like molecules (ubls) is an important regulatory process within cells, playing key roles in controlling many biological ses including cell division, cell signaling and the immune response. Ubls are small proteins that are covalently attached to a lysine on a target protein via an isopeptide linkage with a C-terminal glycine of the ubl. The ubiquitin-like molecule alters the molecular surface of the target protein and can affect such properties as protein-protein interactions, enzymatic ty, stability and cellular localization of the target.

Ubiquitin and other ubls are activated by a specific E1 enzyme which catalyzes the formation of an acyl—adenylate intermediate with the C-tenninal e of the ubl. The activated ubl moleCule is then transferred to the catalytic cysteine e within the E1 enzyme through formation of a thioester bond intermediate. The E1—ubl intermediate and an E2 ate, resulting in a thioester exchange wherein the ubl is transferred to the active site cysteine of the E2. The ubl is then conjugated to the target protein, either directly or in conjunction with an E3 ligase, through isopeptide bond formation with the amino group of a lysine side chain in the target protein.

The biological consequence of ubl cation depends on the target in question.

Ubiquitin is the best characterized of the ubls and a consequence of modification by ubiquitination is the ation of poly-ubiquitinated proteins by the 268 some. Ubiquitin is conjugated to its target proteins through an enzymatic cascade involving its ic E1 ting , Uba1 (ubiquitin activating enzyme, UAE), a conjugating enzyme from the family of E25, and a tin ligase from either the RING or HECT classes of E3s. See, Huang et at, Oncogene, 23:1958-71 (2004). Target specificity is controlled by the particular combination of E2_and E3 protein, with >40 E25 and >100 E35 being known at present. In on to ubiquitin, there are at least 10 ubiquitin-like proteins, each believed to be activated by a specific E1 activating enzyme and processed through similar but distinct downstream conjugation pathways. Other ubls for which E1 activating enzymes have been fied e Nedd8 (APPBP1-Uba3), ISG15 (UBE1 L) and the SUMO family (Aos1-Uba2). ' [005] The ubl Nedd8 is activated by the dimer Nedd8-activating enzyme (APPBP1-Uba3) (NAE) and is erred to a single E2 (ch12), ultimately resulting in on to cullin proteins. The function of neddylation is the activation of cullin-based ubiquitin ligases involved in the tination and hence turnover of many cell cycle and cell signaling proteins, including p27 and I-KB. See Pan et ai., ne. 23:1985-97 . The ubl SUMO is activated by the heterodimer sumo activating enzyme (Aos1-Uba2) (SAE) and is transferred to a single E2 (ch9), followed by coordination with multiple E3 ligases, ultimately resulting in ation of target ns. Sumo modification can affect the cellular localization of target proteins and proteins modified by SUMO family members are involved in nuclear transport, signal transduction and the stress response. See Seeler and Dejean, Nat Rev Moi Cell Biol. 4:690-9, (2003). The function of sumoylation includes tion of calf signaling ys (e.g., cytokine, WNT, growth factor, and steroid hormone signaling) involved in transcription regulation; as well as pathways involved in control of genomic integrity (e.g., DNA replication, response to DNA , recombination and repair). See Muller et ai, Oncogene. 23:1998—2006, (2004). There are other ubls (e.g., ISG15, FAT10, Apg12p) for which the biological functions are still under investigation.

A particular pathway of ance which is regulated via E1 activating enzyme activities is the ubiquitin-proteasome pathway (UPP). As discussed above, the enzymes UAE and NAE te the UPP at two different steps in the ubiquitination cascade. UAE activates ubiquitin in the first step of the cascade, while NAE, via activation of Nedd8, is responsible for the activation of the cullin based ligases, which in turn are required for the final transfer of ubiquitin to certain target proteins A functional UPP pathway is required for normal cell maintenance. The UPP plays a central role in the turnover of many key regulatory ns involved in transcription, cell cycle progression and apoptosis, all of which are important in disease states, including tumor cells. See, e.g., King etai., Science 274: 1652-1659 (1996); Vorhees et at, Clin. Cancer Res, 9: 6316-6325 (2003); and Adams ef al., Nat. Rev. Cancer, 4: 349-360 (2004). Proliferating cells are particularly sensitive to inhibition of the UPP. See, Drexler, Proc. Natl. Acad. Sci., USA 94: 855—860 (1977). The role of the UPP pathway in oncogenesis has led to the investigation of proteasome inhibition as a potential anticancer therapy. For example, modulation of the UPP y by inhibition of the 268 proteasome by VELCADE® (bortezomib) has proven to be an ive treatment in certain s and is approved for the treatment of multiple myeloma and mantle cell lymphoma patients who have received at least one prior therapy. Examples of proteins whose levels are controlled by cullin-based ubiquitin ligases which are downstream of NAE and UAE activity include the CDK inhibitor p27Kip1 and the inhibitor of NFKB, IKB. See, Podust ef al., Proc. Natl. Acad. Sci, 97: 4579-4584 (2000), and Read et at, Mol. Cell Biol, 20: 2326-2333 (2000). Inhibition of the degradation of p27 is expected to block the progression of cells through the G1 and 3 phases of the cell cycle. Interfering with the degradation of IKB should prevent the nuclear localization of NF-KB, transcription of s dependent genes associated with the malignant phenotype, and resistance to standard cytotoxic therapies. onally, NF-KB plays a key role in the expression of a number of pro-inflammatory ors, implicating a role for such inhibitors in inflammatory diseases. Furthermore, inhibition of UPP has been implicated as a useful target for additional therapeutics, such as inflammatory disorders, including, 9.9., toid arthritis, asthma, multiple sclerosis, sis and reperfusion injury; egenerative ers, including e.g., Parkinson's disease, Alzheimer’s disease, triplet repeat disorders; neuropathic pain; ischemic disorders, e.g., stroke, infarction, kidney disorders; and cachexia.

Targeting E1 activating enzymes provides a unique opportunity to interfere with a variety of biochemical pathways important for maintaining the ity of cell division and cell signaling.

E1 activating enzymes function at the first step of ubl conjugation pathways; thus, inhibition of an E1 activating enzyme will specifically modulate the downstream biological consequences of the ubl modification. As such, inhibition of these ting enzymes, and the resultant inhibition of downstream effects of ubl-conjugation, represents a method of interfering with the integrity of cell division, cell signaling, and several aspects of cellular physiology which are important for disease mechanisms. Thus, E1 enzymes such as UAE, NAE, and SAE, as regulators of diverse cellular functions, are potentially important eutic targets for the identification of novel ches to treatment of diseases and ers.

In some embodiments, Form I is characterized by an XRPD pattern substantially as shown in Figure 4. {050] In some embodiments, Form I is characterized by an XRPD pattern having a reference peak with a 26 angle of 4.5 :I: 0.3”, and having peaks at 26 angles of 10.7°, 168°, 17.30 and 19.5“ relative to the reference peak. The term "reference peak" refers to a peak in the XRPD diffractogram that one skilled in the art considers as informing the polymorphic form of the material, i.e., entiated from ment noise. By "relative" it is meant that the observed 26 angle of each peak will be the sum of the 26 angle of the reference peak and the relative 26 angle of that peak. For example, if the reference peak has a 26 angle of 4.4“, the relative peaks will have 26 angles of 15.1°, 21 .2°, 21.7° and 239°; if the reference peak has a 26 angle of 4.5“, the relative peaks will have 26 angles of 15.2“, 21.3“, 21 .8° and 240°; if the nce peak has a 26 angle of 4.6“, the relative peaks will have 26 angles of 15.3”, 21.4°, 21 .9° and 24.1 °; etc. In some embodiments, Form I is characterized by an XRPD pattern having a reference peak with a 26 angle of 4.5 :I: 0.3“, and having peaks at 26 angles of 3.0“, 9.9“, 10.1“, 10.7“, 11.4“, 15.0“, 16.8“, 17.3“, 17.9“, 18.2“, 19.5“ and 20.3“ ve to the reference peak.

Figure 5 shows a differential scanning calorimetry (DSC) profile of Form I. The DSC thermogram plots the heat flow as a function of temperature from a sample, the temperature rate change being about 10 . In some embodiments, Form I is characterized by a D80 profile substantially as shown in Figure 5. Figure 5 shows an endotherm event with onset of about 129.8“0 and peak at about 135.6°C corresponding to the loss of water coupled with melting. A broad erm with an onset of about 181.6“C and peak at about 195.5°C, and a sharp endotherm with an onset of about C and peak at about 275.5“C are also observed.

USES The chemical entities of this invention are useful inhibitors of E1 enzyme activity. In particular, the chemical entities are designed to be inhibitors of NAE. Inhibitors are meant to include chemical entities which reduce the promoting effects of E1 enzymes in ubl (in particular, Nedd8) conjugation to target proteins (6.9., reduction of ubiquitination, neddylation), reduce intracellular signaling mediated by ubl (in ular, Nedd8) conjugation, and/or reduce proteolysis mediated by ubl (in particular, Nedd8) conjugation (e.g., inhibition of cullin-dependent ubiquitination and proteolysis (e.g., the ubiquitin—proteasome pathway)). Thus, the chemical entities of this invention may be assayed for their ability to inhibit the E1 enzyme in vitro or in vivo, or in cells or animal models according to methods provided in further detail herein, or methods known in the art. The chemical entities may be assessed for their ability to bind or mediate E1 enzyme activity directly. Alternatively, the activity of the chemical entities may be assessed through indirect cellular assays, or assays ing downstream s of E1 activation to assess inhibition of downstream effects of E1 tion (e.g., inhibition of - dependent ubiquitination and proteolysis). For example, activity may be assessed by detection of njugated substrates (e.g., ubl-conjugated E2s, ated cullins, ubiquitinated substrates); ion of downstream protein substrate stabilization (e.g., stabilization of p27, stabilization of IKB); ion of inhibition of UPP ty; detection of downstream effects of protein E1 inhibition and substrate ization (e.g., reporter assays, e.g., NFKB reporter assays, p27 reporter ). Assays for assessing activities are described below in the Experimental section and/or are known in the art.

After sonication samples were placed on wet ice, poured into orf tubes and spun at 14000 rpm for 20 min at 4°C in a microfuge. Supernatants were transferred to new tubes and protein concentrations were ined using the Pierce bicinchoninic acid (BOA) reagents and protein standards. Tumor lysates were stored at -80°C.

For quantitative analysis of neddylated cullins the procedure was as follows: 20 pg of tumor lysate with lithium dodecyl sulfate (LDS) loading buffer and sample reducing agent (lnvitrogen NP0007 and NP0004) was loaded onto 442% is gels, 1.5 mM, 10 well gels rogen NP0315Box). Gels were run at 150V in 2—(N-morpholino) ethane sulfonic acid (MES) running buffer (lnvitrogen NP0002). Gels were cut at appropriate molecular weight marker and transferred to L (Millipore, IPFL00010) using a semi dry transfer apparatus (Amersham Biosciences, TE70). After transfer, membranes were blocked in y blocker (Ll-COR Biosciences # 927-40000), then incubated with y antibodies in Odyssey r + 0.1% Tween-20 (Sigma #P7949) overnight at 4 degrees. Membranes were washed three times in tris buffered saline with Tween-20 (TBST) and then incubated with Alexa Fluor 680 labeled goat anti-rabbit immunoglobulin G, heavy and light chain (lgG (H+L)) antibody (Molecular Probes Cat # A-21109). After 1 hour incubation with secondary antibody in the dark, membranes were washed 5 times with TBST and once with tris buffered saline (TBS), protected from light. Membranes were dried for at least one hour and then scanned with the Odyssey Infrared Imaging System (Ll-COR ences). The following primary antibody was used: Anti-Nedd-8 (MIL10 clone 525, developed with E-pitomics, dilution of 1:4000). Secondary antibody was used at 1:2000. Quantitation of signals on Western blots was performed with the Odyssey software.
