solid-phase synthesis of a low molecular weight RGD mimetic library is described. Activities of the compounds in inhibiting the interaction of ligands, vitronectin and fibrinogen, with isolated immobilized integrins alphavbeta3 and alphaIIbbeta3 were determined in a screening assay. Highly active and selective nonpeptide alphavbeta3 integrin antagonists with regard to orally bioavailability were developed
描述了低分子量RGD模拟物库的固相合成。在筛选分析中确定了化合物在抑制配体,玻连蛋白和纤维蛋白原与分离的固定化整合素αvbeta3和αIIbbeta3相互作用中的活性。基于含氮杂甘氨酸的先导化合物1,开发了具有高活性和选择性的非肽αvbeta3整联蛋白拮抗剂,具有口服生物利用度。一个重要的变化是芳香残基取代了天冬酰胺1。此外,已经引入了不同的胍模拟物以改善药代动力学特征。一组RGD模拟物中的亚甲基部分与β-氨基酸NH的交换产生了代表一种新型拟肽方法的杜鹃花类似物化合物,
