本发明提供了式I的新型caspase抑制剂:
其中,R1是氢,CHN2,R或—CH2Y; R是脂肪基团,芳基团,芳基烷基团,杂环基团或杂环基烷基团; Y是电负性离去基团; R2是CO2H,CH2CO2H或其酯,酰胺或异构体; X2-X1是N(R3)—C(R3),C(R3)2—C(R3),C(R3)2—N,N═C,C(R3)═C,C(═O)—N或C(═O)—C(R3); 每个R3独立地选择自氢或C1-6脂肪基; 环C是螺合芳基环; n为0、1或2; 环A中的每个亚甲基碳原子可以选择性地且独立地被═O或一个或多个卤素、C1-4烷基或C1-4烷氧基取代。这些化合物可用于治疗caspase介导的疾病。
