Replacing the Pro6 in the p6(Gag)-derived 9-mer "P-E-P-T-A-P-P-E-E" with N-substituted glycine (NSG) residues is problematic. However, incorporation of hydrazone amides ("peptoid hydrazones") can be readily achieved in library fashion. Furthermore, reduction of these hydrazones to N-substituted "peptoid hydrazides" affords a facile route to library diversification. This approach is demonstrated by
用N-取代的甘氨酸(NSG)残基替换p6(Gag)衍生的9-mer“ PEPTAPPEE”中的Pro6是有问题的。然而,酰胺的掺入(“类肽”)可以以文库方式容易地实现。此外,将这些还原为N-取代的“类肽酰肼”提供了实现文库多样化的简便途径。通过将这种方法应用于被设计为潜在的HIV萌芽拮抗剂的Tsg101结合化合物,可以证明这一方法。[反应:看文字]
