Abstract

Bruton's tyrosine kinase (Btk) has been shown to play a key role in the pathogenesis of autoimmunity. Therefore, the inhibition of the kinase activity of Btk with a small molecule inhibitor could offer a breakthrough in the clinical treatment of many autoimmune diseases. This Letter describes the discovery of BMS-986143 through systematic structure-activity relationship (SAR) development. This compound benefits from defined chirality derived from two rotationally stable atropisomeric axes, providing a potent and selective single atropisomer with desirable efficacy and tolerability profiles.
