技术领域
本发明涉及药物化学、制备方法及应用,特别涉及N-(4-(嘧啶-4-氨基)苯基)磺酰胺类抑制剂或其可药用的盐、其制备方法及用途。
背景技术
热休克蛋白Hsp90及其辅助伴侣分子Cdc37是人体内大量存在的一类蛋白-蛋白相互作用。在癌症细胞中,Hsp90-Cdc37蛋白表达量显著升高,协助正确折叠Hsp90的激酶类客户蛋白,促进肿瘤细胞的增殖,加速疾病的发生与发展。因此,抑制Hsp90-Cdc37相互作用可以达到治疗肿瘤的目的。
Cdc37首先结合未成熟的激酶类客户蛋白,随后与Hsp90二聚体结合形成多元复合物,在ATP供能的条件下协助激酶类蛋白正确折叠后释放。Hsp90-Cdc37相互作用的客户蛋白均为蛋白激酶,与肿瘤的发生发展关系密切。抑制Hsp90-Cdc37蛋白间的相互作用,特异性地调控其激酶类客户蛋白的成熟过程,进而通过泛素化途径降解。
目前,针对Hsp90介导的相关疾病的研究主要集中于ATP竞争型抑制剂,并先后有二十余个小分子抑制剂进入临床,然而其均表现出选择性不强及毒性较大等副作用。因此,选择性的抑制Hsp90-Cdc37相互作用可以提高Hsp90抑制剂的选择性,降低毒副作用,提高以Hsp90为信号通路的治疗效果,具有较大的临床应用前景。
