A novel class of nonantioxidant dual inhibitors of both CO and 5-LO is described. The balance between the activity against CO and 5-LO can be shifted by modifying the substitution pattern of the phenyl moiety at the 6-position of the pyrrolizine ring. Structure-activity relationships are discussed. Compound 3e with a 4-Cl substituent (IC50 = 0.21 microM (CO); 0.18 microM (5-LO)) and 3n with a 4-OCH3
描述了一类新型的CO和5-LO的非抗氧化剂双重抑制剂。通过修饰吡咯烷嗪环的6-位上的苯基部分的取代模式,可以改变对CO和5-LO的活性之间的平衡。讨论了构效关系。具有4-Cl取代基(IC50 = 0.21 microM(CO); 0.18 microM(5-LO))的化合物3e和具有4-OCH3取代基(IC50 = 0.1 microM(CO); 0.24 microM(5-LO)的化合物3e)是这两种酶最有效且平衡最强的双重抑制剂。用牛血小板完整细胞测定法测定CO的抑制,用完整牛PMNL测定5-LO的抑制率。还在人细胞中研究了化合物3e。
