A series of novel substituted purines containing a side chain with a terminal amino or guanidyl group were designed and synthesized as HIV-1 Tat-TAR inhibitors. All the compounds could effectively block the TAR transactivation in human 293T cells with the CAT expression percentage ranging from 34.4% to 65.7% and showed high antiviral effects with low cytotoxicities in inhibiting the formation of SIV-induced
设计并合成了一系列新颖的含侧链带有末端氨基或胍基的嘌呤,它们是HIV-1 Tat-TAR抑制剂。所有这些化合物都可以有效地阻断人293T细胞中的TAR反式激活,其CAT表达百分比范围为34.4%至65.7%,并且在抑制SIV诱导的CEM174细胞合胞体形成方面显示出高抗病毒作用和低细胞毒性。通过自动对接过程进行的分子建模研究表明,这些化合物以两种不同的方式与TAR RNA结合。
