The design, synthesis, and pharmacological evaluation of L-734,217, a potent, low-molecular weight, orally active fibrinogen receptor antagonist, is reported. A strategy for producing low-molecular weight inhibitors from the peptide c-[(Ac)CRGDC] A, previously reported from these laboratories, is outlined. This strategy combines a retrodesign analysis of the conformationally defined cyclic peptide
据报道,L-734,217是一种有效的,低分子量,口服活性的纤维蛋白原受体拮抗剂,其设计,合成和药理评价。概述了由这些实验室先前报道的由肽c-[(Ac)CRGDC] A生产低分子量抑制剂的策略。该策略将对构象定义的环肽A的逆向设计分析与精氨酸-甘氨酸-天冬氨酸(RGD)三肽序列中存在的立体化学信息结合在一起,最终发现了L-734,217。L-734,217在浓度低于100 nM时抑制人,狗和黑猩猩的血小板聚集,并且在抑制人脐静脉内皮细胞对血纤蛋白原,纤连蛋白,和玻连蛋白在抑制血小板聚集方面的作用。L-734,217在狗和黑猩猩分别以1.0和2.0 mg / kg的剂量口服后显示出显着的离体抗血小板活性,并已被选作抗栓剂作为临床候选药物。
