A series of oxamyl dipeptides were optimized for pan caspase inhibition, anti-apoptotic cellular activity and in vivo efficacy. This structure-activity relationship study focused on the P4 oxamides and warhead moieties. Primarily on the basis of in vitro data, inhibitors were selected for study in a murine model of alpha-Fas-induced liver injury. IDN-6556 (1) was further profiled in additional in vivo
针对泛半胱天冬酶抑制,抗凋亡细胞活性和体内功效优化了一系列草酰二肽。这项结构-活性关系研究的重点是P4乙酰胺和弹头部分。主要根据体外数据,在α-Fas诱导的肝损伤小鼠模型中选择抑制剂进行研究。IDN-6556(1)在其他体内模型和药代动力学研究中得到了进一步的描述。现在,这种一流的胱天蛋白酶抑制剂已成为两项II期临床试验的主题,评估了其在肝病中使用的安全性和有效性。
