Definitions

  • the description provides bifunctional compounds comprising a target protein binding moiety and an E3 ubiquitin ligase binding moiety, and associated methods of use.
  • the bifunctional compounds are useful as modulators of targeted ubiquitination, especially with respect to Rapidly Accelerated Fibrosarcoma (RAF) proteins, which are degraded and/or otherwise inhibited by bifunctional compounds according to the present disclosure.
  • RAF Rapidly Accelerated Fibrosarcoma
  • E3 ubiquitin ligases confer substrate specificity for ubiquitination, and therefore, are more attractive therapeutic targets than general proteasome inhibitors due to their specificity for certain protein substrates.
  • the development of ligands of E3 ligases has proven challenging, in part due to the fact that they must disrupt protein-protein interactions.
  • recent developments have provided specific ligands which bind to these ligases.
  • Tumor suppressor gene p53 plays an important role in cell growth arrest and apoptosis in response to DNA damage or stress (A. Vazquez, et al. Nat. Rev. Drug. Dis. (2008), 7, 979-982), and inactivation of p53 has been suggested as one of the major pathway for tumor cell survival (A. J. Levine, et al. Nature (2000), 408, 307-310).
  • M. Hollstein, et al. Science (1991), 233, 49-53) patients with wild type p53 were often found p53 down regulation by MDM2 through the protein-protein interaction of p53 and MDM2 (P. Chene, et al. Nat.
  • MDM2 keeps p53 at low concentration.
  • p53 level increases, and that also causes increase in MDM2 due to the feedback loop from p53/MDM2 auto regulatory system.
  • p53 regulates MDM2 at the transcription level
  • MDM2 regulates p53 at its activity level (A. J. Levine, et al. Genes Dev. (1993) 7, 1126-1132).
  • MDM2 binds to N-terminal domain of p53 and blocks expression of p53-responsive genes (J. Momand, et al. Cell (1992), 69, 1237-1245). Second, MDM2 shuttles p53 from nucleus to cytoplasm to facilitate proteolytic degradation (J. Roth, et al. EMBO J. (1998), 17, 554-564). Lastly, MDM2 carries intrinsic E3 ligase activity of conjugating ubiquitin to p53 for degradation through ubiquitin- dependent 26s proteasome system (UPS) (Y. Haupt, et al. Nature (1997) 387, 296-299). As such, because MDM2 functions as E3 ligase, recruiting MDM2 to a disease causing protein and effectuating its ubiquitination and degradation is an approach of high interest for drug discovery.
  • UPS ubiquitin- dependent 26s proteasome system
  • VHL von Hippel-Lindau
  • VCB the substrate recognition subunit of the E3 ligase complex
  • the primary substrate of VHL is Hypoxia Inducible Factor 1a (HIF-1a), a transcription factor that upregulates genes such as the pro- angiogenic growth factor VEGF and the red blood cell inducing cytokine erythropoietin in response to low oxygen levels.
  • HIF-1a Hypoxia Inducible Factor 1a
  • VHL Von Hippel Lindau
  • Cereblon is a protein that in humans is encoded by the CRBN gene. CRBN orthologs are highly conserved from plants to humans, which underscores its physiological importance. Cereblon forms an E3 ubiquitin ligase complex with damaged DNA binding protein 1 (DDB1), Cullin-4A (CUL4A), and regulator of cullins 1 (ROC1). This complex ubiquitinates a number of other proteins. Through a mechanism which has not been completely elucidated, cereblon ubquitination of target proteins results in increased levels of fibroblast growth factor 8 (FGF8) and fibroblast growth factor 10 (FGF10). FGF8 in turn regulates a number of developmental processes, such as limb and auditory vesicle formation. The net result is that this ubiquitin ligase complex is important for limb outgrowth in embryos. In the absence of cereblon, DDB1 forms a complex with DDB2 that functions as a DNA damage-binding protein.
  • DDB1 forms a complex
  • IAPs Inhibitors of Apotosis Proteins
  • the human IAP family includes 8 members, and numerous other organisms contain IAP homologs.
  • IAPs contain an E3 ligase specific domain and baculoviral IAP repeat (BIR) domains that recognize substrates, and promote their ubiquitination. IAPs promote ubiquitination and can directly bind and inhibit caspases.
  • Caspases are proteases (e.g. caspase-3, caspase-7 and caspace-9) that implement apoptosis. As such, through the binding of caspases, IAPs inhibit cell death.
  • DIABLO also known as second mitrochondria-derived activator of caspases or SMAC
  • HTRA2 also known as Omi
  • SMAC interacts with essentially all known IAPs including XIAP, c-IAP1, c-IAP2, NIL-IAP, Bruce, and survivin.
  • IAPs including XIAP, c-IAP1, c-IAP2, NIL-IAP, Bruce, and survivin.
  • the first four amino acids (AVPI) of mature SMAC bind to a portion of IAPs, which is believed to be essential for blocking the anti-apoptotic effects of IAPs.
  • Bifunctional compounds such as those that are described in U.S. Patent Application Publications 2015-0291562 and 2014-0356322 (incorporated herein by reference), function to recruit endogenous proteins to an E3 ubiquiuin ligase for degradation.
  • the publications describe bifunctional or proteolysis targeting chimeric (PROTAC) compounds, which find utility as modulators of targeted ubiquitination of a variety of polypeptides and other proteins, which are then degraded and/or otherwise inhibited by the bifunctional compounds.
  • RAF Rapidly Accelerated Fibrosarcoma
  • current BRaf inhibitors such as, vemurafenib and dabrafenib
  • diseases or disorders such as, melanoma, lung cancer, pancreatic cancer, and/or colorectal cancers
  • resistance mutations can emerge in response to BRaf/MEK inhibitor therapy.
  • the p61 splice variant can emerge in melanoma patients treated with BRaf/MEK inhibitor therapy, which leaves these patients with no clinical options.
  • BRaf/MEK inhibitor therapy Currently marketed agents also bind to and cause paradoxical activation of wild-type BRaf, which results in clinical complications.
  • the family of hypoactive Class III BRaf mutants that signal through heterodimerization with CRaf constitute 40% of BRaf mutations in non-small cell lung cancer (NSCLC), and also appear sporadically across other cancers, cannot be targeted with any currently approved or clinical-stage BRaf inhibitors.
  • NSCLC non-small cell lung cancer
  • Class I BRAF mutants (V600E, V600K, V600D) have high kinase activity, are Ras and dimerization independent, and are sensitive to vemuragenib.
  • Class II BRAF mutants has high to intermediate kinase activity, are Ras- independent and dimerization dependent, and are insensitive to vemurafenib.
  • Class III BRAF mutatns have lot to no kinase activity, are Ras and dimerization dependent, and are insensitive to vemurafenib.
  • the present disclosure describes bifunctional compounds which function to recruit endogenous proteins to an E3 ubiquitin ligase for degradation, and methods of using the same.
  • the present disclosure provides bifunctional or proteolysis targeting chimeric (PROTAC) compounds, which find utility as modulators of targeted ubiquitination of a variety of polypeptides and other proteins, which are then degraded and/or otherwise inhibited by the bifunctional compounds as described herein.
