and leukocyte integrins is reported. The compound library was evaluated by investigating the effects on integrin-mediated cell adhesion and cell signaling in cell lines expressing αvβ3, αvβ5, αvβ6, α5β1, αIIbβ3, α4β1, and αLβ2 integrins. SAR analysis of the new series of azetidinones enabled the recognition of structural elements associated with integrin selectivity. We obtained selective and potent agonists
报道了设计和合成靶向RGD结合和白细胞整联蛋白的一系列新的β-内酰胺衍生物。所述化合物库通过研究对整合素介导的细胞粘附和细胞系中的细胞信号传导表达α的影响评价v β 3,α v β 5,α v β 6,α 5 β 1,α IIB β 3,α 4 β 1,以及α大号β 2整联蛋白。新的氮杂环丁酮系列的SAR分析使人们认识到与整联蛋白选择性有关的结构元素。我们获得选择性和可诱导的细胞粘附和促进细胞有效激动剂信令α介导的v β 3,α v β 5,α 5 β 1,或α 4 β 1整合素,和拮抗剂的整α v β 3和α 5 β 1,以及α 4 β 1和α大号β 2,防止了由各自的内源性激动剂引起的作用。
