Definitions

• the present disclosure provides certain bicyclic heteroaryl phosphonate and boronate compounds that inhibit ectonucleotide pyrophosphatase/ phosphodiesterase 1 (ENPP1) enzymatic activity and are therefore useful for the treatment of diseases treatable by inhibition of ENPP1. Also provided are pharmaceutical compositions containing such compounds and processes for preparing such compounds.
• ENPP1 ectonucleotide pyrophosphatase/ phosphodiesterase 1
• ENPP1 enzyme is present in a wide range of tissues and cell types, such as lymphocytes, macrophages, liver, brain, heart, kidney, vascular smooth muscle cells, and chondrocytes.
• ENPP1 hydrolyzes ATP and other nucleoside triphosphates and releases AMP or other nucleoside monophosphates as well as pyrophosphate (PPi) (Kato K et al. 2012 PNAS 109:16876-16881; Hessle L et al. 2002 PNAS 99:9445-9449).
• the enzyme can also hydrolyze other nucleoside monophosphate esters (Kato K et al. 2012 PNAS 109:16876-16881).
• ENPP1 has been identified as the dominant 2’-3’-cGAMP hydrolase in cultured cells, tissue extracts and blood (Li L et al. 2014 Nat Chem Biol 10:1043-1048). Tissues and blood from ENPP1 knockout mice lack 2’-3’- cGAMP hydrolase activity. Elevated levels of ENPP1 have been associated with calcific aortic valve disease (CAVD) and calcium pyrophosphate dihydrate (CPPD) disease, an inflammatory disease resulting from CPPD crystal deposits in the joint and surrounding tissues (Cote N et al. 2012 Eur J Pharmacol 689:139-146; Johnson K et al. 2001 Arthritis Rheum 44: 1071).
• CAVD calcific aortic valve disease
• CPPD calcium pyrophosphate dihydrate
• ENPP1 expression is upregulated in certain hepatocellular carcinomas, glioblastomas, melanomas, testicular, pancreatic and thyroid and breast cancers and has been associated with resistance to chemotherapy (see Lau WM et al. 2013 PLoS One 8:5; Bageritz J et al. 2014 Mol Cell Oncology 1:3; Bageritz J et al. 2014 Cell Death, Differentiation 21:929-940; Umar A et al. 2009 Mol Cell Proteomics 8:1278-1294).
• ENPP1 upregulation and variants of ENPP1 are also associated with insulin resistance and type 2 diabetes (Meyre D et al. 2005 Nat Genet 37:863-867; Maddux BA et al.
• Cyclic GMP-AMP synthase is a pattern recognition receptor that synthesizes the endogenous messenger molecule cGAMP from ATP and GTP in response to the presence of DNA derived from viruses, bacteria, damaged mitochondria or cancer cells.
• the cGAMP molecule then binds to the stimulator of interferon genes (STING) protein, which initiates a signaling response that activates innate immunity and results in the production of type I interferon, antiviral and immune-stimulatory cytokines (Sun L et al. 2013 Science 339:786-791; Wu J et al. 2013 Science 339:826-830; Gao D et al.
• the cGAS enzyme, cGAMP messenger and STING are is also involved in host defense against RNA viruses and the immune control of tumor development (Aguirre S et al. 2012 PLoS Pathog 8: el002934; Barber GN 2015 Nat Rev Immunol 15:760-770).
• ENPP1 has been identified as the enzyme that naturally hydrolyzes cGAMP and therefore counteracts the innate immune response against infectious agents, damaged cells and cancer cells (Li L et al. 2014 Nat Chem Biol 10:1043-1048).
• the efficacy of non-hydro lyzable cGAMP analogs in inducing functional immune responses is higher than that of natural, hydro lysable cGAMP (Li L et al.
• Inhibitors of cGAMP hydrolysis may therefore be used to increase the effectiveness of immune responses against cancer cells and tumors and against infections by RNA or DNA viruses or bacteria.
• Inhibitors of ENPP1 and of cGAMP or nucleoside triphosphate hydrolysis may also be used for the treatment of inflammatory diseases that are associated with elevated nucleotidase levels, reduced nucleoside triphosphate, reduced cGAMP or reduced nucleoside monophosphate ester levels or diseases associated with elevated nucleoside or nucleoside monophosphate levels.
