Isoxazoline‐containing peptidomimetics, designed to be effective αvβ3 and α5β1 integrin ligands, were synthesized through an original procedure involving N,O‐bis(trimethylsilyl)hydroxyamine conjugate addition to alkylidene acetoacetates, followed by intramolecular hemiketalization. To mimic the RGD recognition sequence, basic and acidic terminal appendages were introduced, and the final products were
含异恶唑啉肽模拟物,设计为有效α v β 3和α 5 β 1整联配体,通过涉及的原始程序合成Ñ,ö-将亚烷基双(三甲基甲硅烷基)羟胺共轭物添加到乙酰乙酸酯中,然后进行分子内半缩酮化。为了模拟RGD识别序列,引入了碱性和酸性末端附件,并在细胞粘附抑制试验中测试了最终产物。证明所有合成的化合物都是整联蛋白受体的优秀配体,并且通过评估纤连蛋白诱导的ERK磷酸化证明了其对细胞内信号传导和磷酸化途径的强烈影响。对接实验的结果表明了观察到的抑制活性的分子基础。
