A set of cyclic peptide analogues of a selective CXCR4 antagonist FC131 [cyclo(-D-Tyr-Arg-Arg-Nal-Gly-)] were synthesized and bioevaluated. Using (E)-alkene and (Z)-fluoroalkene dipeptide isosteres for Arg-Arg and Arg-Nal substructures, indispensable or the partial contribution of the two peptide bonds to the CXCR4 antagonism and anti-HIV activity was demonstrated. FC131 and the analogues were shown
选择性CXCR4拮抗剂FC131的一组环肽类似物[环(-D -Tyr-Arg-Arg-Nal-Gly-)合成和生物评价。使用(E)-烯烃 和 (Z)-氟烯烃二肽 的等位基因 精氨酸 和 精氨酸证明了两个肽键对CXCR4拮抗作用和抗HIV活性必不可少的部分或部分贡献。FC131及其类似物显示出选择性抑制作用SDF-1 与CXCR4结合,而没有观察到SDF-1与CXCR7结合的抑制作用。
