analogues, the structures of which encompass and surpass variations seen in natural batzelladines, for their ability to inhibit HIV-1 envelope-mediated cell-cell fusion. Clear structure-activity relationships were revealed and indicated that the best inhibitors of fusion were most similar in structure to natural batzelladine F, with IC50 values ranging from 0.8 to 3.0 microM. Proceeding from the earlier

天然产物(例如蛤贝类和巴兹拉丁)对某些病毒(包括HSV和HIV)具有抗病毒活性。在这项研究中,我们评估了一个包含28个batzelladine类似物的合成文库,它们的结构包含并超过了天然batzelladines中的变异,具有抑制HIV-1包膜介导的细胞融合的能力。揭示了明确的结构-活性关系,并表明最佳的融合
抑制剂在结构上与天然巴兹拉定F最相似,IC50值在0.8至3.0 microM之间。从较早的发现出发,一些巴兹拉汀阻断了gp120-C
