Thirty-two quinoline derivatives were designed and synthesized as HIV-1 Tat–TAR interaction inhibitors. All the compounds showed high antiviral activities in inhibiting the formation of SIV-induced syncytium in CEM174 cells. Nine of them with low cytotoxicities were evaluated by Tat dependent HIV-1 LTR-driven CAT gene expression colorimetric enzyme assay in human 293T cells, indicating effective inhibitory
设计并合成了32种喹啉衍生物作为HIV-1 Tat-TAR相互作用抑制剂。所有这些化合物在抑制CEM174细胞中SIV诱导的合胞体形成方面均表现出很高的抗病毒活性。在人的293T细胞中,通过Tat依赖HIV-1 LTR驱动的CAT基因表达比色酶分析评估了其中9种低细胞毒性,表明它们具有有效的抑制Tat-TAR相互作用的抑制活性。分子模拟实验表明,这些化合物可能通过与Tat蛋白而非TAR RNA结合而抑制Tat-TAR相互作用。
