linear and cyclic analogues of the VEGF81–91 fragment are described. Cyclic 11- and 10-mer peptide derivatives were prepared using parallel solid-phase protocols. The formation of hydrocarbon alkene-bridged cyclic peptides was achieved through optimized ring-closing metathesis reactions from linear derivatives with conveniently located allylGly residues. Alkane-bridged analogues were successfully obtained
描述了VEGF 81-91片段的线性和环状类似物小文库对VEGFR-1受体的设计,合成和结合亲和力。使用平行固相方案制备环状的11-mer和10-mer肽衍生物。通过优化的具有方便位置的烯丙基甘氨酸残基的线性衍生物的闭环复分解反应,可以实现烃链桥连环肽的形成。烯醛桥联的类似物是通过别处的树脂上加氢成功获得的。结合测定表明,这些化合物中的某些能够与标记的VEGF竞争与VEGFR-1受体的相互作用。几个肽衍生物,2,7和8,显示适度但重要的结合亲和力,表明设计的肽可以模仿VEGF 81-91片段,从而破坏VEGF / VEGFR-1的相互作用。这一事实为使用这些肽作为生物学/药理学工具深入研究这种蛋白质-蛋白质系统的起点开辟了道路。
