A systematic study of interleukin-1 beta converting enzyme (ICE, caspase-1) and caspase-3 (CPP32, apopain) inhibitors incorporating a P2-P3 conformationally constrained dipeptide mimetic is reported. Depending on the nature of the P4 substituent, highly selective inhibitors of both Csp-1 or Csp-3 were obtained.
报道了对白介素-1β转化酶(ICE,半胱天冬酶-1)和半胱天冬酶-3(CPP32,凋亡蛋白酶)抑制剂进行的一项系统性研究,该抑制剂含有P2-P3构象受限的二肽模拟物。根据P4取代基的性质,获得了对Csp-1或Csp-3两者均具有高度选择性的抑制剂。
