The integrin receptor recognition sequence Arg-Gly-Asp was successfully used as a template from which to develop a series of potent, selective, orally active, peptide-based fibrinogen receptor antagonists with a long duration of action. Simple modifications centered on the Arg and Gly residues quickly led to a modified peptide (1) with significantly enhanced ability to inhibit in vitro platelet aggregation
整联蛋白受体识别序列Arg-Gly-Asp已成功用作模板,从中可开发出一系列作用力强,选择性,口服活性,基于肽的纤维蛋白原受体拮抗剂,且作用时间长。以Arg和Gly残基为中心的简单修饰很快导致修饰肽(1)具有显着增强的抑制体外血小板凝集的能力。哌啶取代1中的胍基提供3,不仅显示出效力的进一步提高,而且显示出适度的口服功效。最后,探索C端氨基酸的侧链功能和羧基末端的性质,得出了一组分子,这些分子在抑制血小板聚集方面表现出优异的体外效力,出色的整联蛋白选择性,
