We synthesized a series of novel 2-anilinopyrazolo[1,5-a]pyrimidine derivatives and evaluated their ability to inhibit c-Src kinase; 7-(2-amino-2-methylpropylamino)-5-cyclopropyl-2-(3,5-dimethoxyphenylamino)pyrazolo[1,5-a]pyrimidine-3-carboxamide 7o and 7-(2-amino-2-methylpropylamino)-2-(3,5-dimethoxyphenylamino)-5-methylpyrazolo[1,5-a]pyrimidine-3-carboxamide 7f showed potent inhibitory activity. Compound 7f inhibited c-Src selectively and exhibited satisfactory central nervous system (CNS) penetration. Furthermore, 7f·HCl reduced the infarct volume in vivo in a rat middle cerebral artery (MCA) occlusion model when administrated intraperitoneally.
我们合成了一系列新型2-苯胺基吡唑并[1,5-a]嘧啶衍生物,并评估了它们抑制c-Src激酶的能力;其中,7-(2-氨基-2-甲基丙基氨基)-5-环丙基-2-(3,5-二甲氧基苯胺基)吡唑并[1,5-a]嘧啶-3-甲酰胺7o和7-(2-氨基-2-甲基丙基氨基)-2-(3,5-二甲氧基苯胺基)-5-甲基吡唑并[1,5-a]嘧啶-3-甲酰胺7f表现出强大的抑制活性。化合物7f对c-Src具有选择性抑制作用,并显示出满意的中枢神经系统(CNS)穿透性。此外,7f·HCl盐酸盐通过腹腔注射给药,在体内降低了大鼠中大脑动脉(MCA)闭塞模型中的梗死体积。
