Incorporation of a suitably-placed electrophilic group transformed a series of reversible BTK inhibitors based on carbazole-1-carboxamide and tetrahydrocarbazole-1-carboxamide into potent, irreversible inhibitors. Removal of one ring from the core of these compounds provided a potent irreversible series of 2,3-dimethylindole-7-carboxamides having excellent potency and improved selectivity, with the
适当放置的亲电基团的引入将基于咔唑-1-甲酰胺和四氢咔唑-1-甲酰胺的一系列可逆BTK抑制剂转化为有效的不可逆抑制剂。从这些化合物的核心上除去一个环,提供了一系列有效的不可逆的2,3-二甲基吲哚-7-羧酰胺,具有优异的效能和改进的选择性,并具有降低亲脂性和分子量的其他优点。
