Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: Branebrutinib (BMS-986195) is a potent, covalent, irreversible inhibitor of the TEC family non-receptor tyrosine kinase, Bruton's tyrosine kinase (BTK) [2]. BTK is essential in antigen-dependent B cell signaling and function, and is a therapeutic target for oncology and rheumatic diseases. Branebrutinib is a clinical lead for the treatment of rheumatoid arthritis, as claimed in Bristol-Myers Squibb's patent US20160115126A1 (Example 223) [1].
