Imidazo[1,5-a]quinoxalines were synthesized that function as irreversible Bruton’s tyrosine kinase (BTK) inhibitors. The syntheses and SAR of this series of compounds are presented as well as the X-ray crystal structure of the lead compound 36 in complex with a gate-keeper variant of ITK enzyme. The lead compound showed good in vivo efficacy in preclinical RA models.
合成了咪唑并[1,5- a ]喹喔啉,它们起不可逆的布鲁顿酪氨酸激酶(BTK)抑制剂的作用。介绍了该系列化合物的合成和SAR以及与ITK酶的守门员变体复合的前导化合物36的X射线晶体结构。铅化合物在临床前RA模型中显示出良好的体内功效。
