In a program aimed at discovering novel protein kinase inhibitors, a convenient synthesis of 3,8-diaminoimidazo[1,2-a]pyrazines has been developed exploiting the isocyanide-based multicomponent Blackburn reaction, followed by a nucleophilic aromatic substitution with ammonia or primary and secondary amines. The potential of the reported scaffold is strengthened by the inhibition of STAT5-dependent
在旨在发现新型蛋白激酶抑制剂的程序中,已经开发了一种方便的合成3,8-二氨基咪唑并[1,2- a ]吡嗪的方法。异氰化物的多组分布莱克本反应,然后用 氨或伯胺和仲胺。通过抑制四种合成化合物显示的STAT5依赖性转录,增强了报道的支架的潜力。
