an imidazole, pyrazine or fenyl ring as the central scaffold, with many congeners displaying strong inhibitory effects against dengue virus (DENV) in cell-based assays. Following up on some literature reports, the rationale was borne out to preserve the pending groups, now attached to either a 2,6-diaminopurine or 2,4-diaminoquinazoline scaffold. Synthetic efforts turned out less straightforward than
先前的努力导致了像甲酰胺,吡嗪或芬尼环这样的二甲酰胺衍生物(如1.3)作为中心支架,在基于细胞的测定中,许多同类物质对登革热病毒(DENV)表现出强大的抑制作用。根据一些文献报道,证实了保留未决基团的理由,这些基团现在已连接到2,6-二氨基嘌呤或2,4-二氨基喹唑啉支架上。合成研究的结果并不像预期的那样简单,但是产生了一些新的衍生物,这些衍生物具有低的微摩尔抗-DENV活性,尽管没有细胞毒性。嘌呤14被证明是该系列中最有效的化合物,EC50为1.9μM,选择性指数为58,而喹唑啉18a 的EC50为2.6μM,SI仅为2。
