profiles of HIV-1 non-nucleoside reverse transcriptase inhibitors (NNRTIs), a novel series of “dual-site” binding diarylpyrimidine (DAPY) derivatives targeting both the NNRTI adjacent site and NNRTIs binding pocket (NNIBP) were designed, synthesized, and evaluated for their anti-HIV potency in TZM-bl and MT-4 cells. Eight compounds exhibited moderate to excellent potencies in inhibiting wild-type (WT)
受到我们先前为改善HIV-1非核苷逆转录酶抑制剂(NNRTIs)的耐药性谱所作的努力的启发,一系列针对NNRTI相邻位点和NNRTIs结合的新型“双位”结合二芳基嘧啶(DAPY)衍生物设计,合成了口袋(NNIBP),并评估了它们在TZM-1b1和MT-4细胞中的抗HIV效力。八种化合物在抑制野生型(WT)HIV-1复制中表现出中度至极强的效力,其EC 50值为2.45 nM至5.36 nM,而14c(EC 50 = 2.45 nM)被证明是最有前途的抑制剂。值得注意的是,14c对单一突变菌株E138K(EC 50 = 10.6nM),与ETR(EC 50 = 9.80nM)相当,并且效力比化合物7(EC 50 = 37.3nM)高3.5倍。此外,14c充当经典NNRTI,对WT HIV-1 RT具有高度亲和力(IC 50 = 0.0589μM)。还确定了代表性化合物的详细结构-活性
