The design, synthesis, conformational studies and binding affinity for VEGF receptors of a collection of linear and cyclic peptide analogues of the N-terminal α-helix fragments 13–25 of VEGF and 1–13 of Vammin are described. Linear 13(14)-mer peptides were designed with the help of an AGADIR algorithm and prepared following peptide solid-phase synthetic protocols. Cyclic peptide derivatives were prepared
描述了一系列VEGF N末端α-螺旋片段13–25和Vammin 1–13的线性和环状肽类似物的设计,合成,构象研究以及对VEGF受体的结合亲和力。借助AGADIR算法设计线性13(14)-mer肽,并按照肽固相合成规程进行制备。通过具有酰胺键的形成,由具有方便定位的Glu和Lys残基的线性前体在树脂上制备环肽衍生物。构象分析,CD和NMR表明,大多数合成的肽在溶液中都有明显的结构化为α-螺旋的趋势。一些肽能够以中等亲和力结合VEGFR-1受体。除了上述关键残基(Phe17,Tyr21和Tyr25)之外,
