inhibitor of the interaction between HIV gp120 and host cell CD4 receptors, on activity in an HIV entry assay was examined. Small substituents at C-4 generally resulted in increased potency whilst substitution at C-7 was readily tolerated and uniformly produced more potent HIV entry inhibitors. Substituents deployed at C-6 and, particularly, C-5 generally produced a modest to marked weakening of potency

抑制剂。与原型相比,部署在C-6(尤其是C-5)上的替代品通常会产生一定程度的效力减弱。N-1处的小烷基取代基对活性的影响最小,同时增加了烷基部分的大小,导致抑制性能逐渐降低。这些研究建立了对HIV附着
