mutants. Specifically, compound 30, which had the highest selectivity index (SI = 16094) and the best anti-reverse transcriptase ability (IC50 = 39 nM), displayed marked inhibitory activity (EC50 = 13.5, 9.4, 17.0, 52.0, and 58.2 nM) against WT, K103N, E138K, L100I, Y181C mutants and moderate activity against double mutants. This study provides important avenues for the further design of HIV-1 inhibitors
目前的工作是继我们初步发现联苯二芳基嘧啶(DAPYs)作为HIV-1非核苷逆转录酶抑制剂。联苯-DAPYs的进一步结构优化导致通过支架跳跃策略鉴定了一系列新的联苯取代的噻吩[3,2-d]嘧啶类似物。该系列产品的生物学评估表明,这些化合物对野生型(WT)HIV-1感染的细胞具有高达一位数的纳摩尔浓度(EC50 = 7.8-526.2 nM),且毒性极低(CC50 = 18.5-280.8μM)。 。此外,结果还证明了化合物29-32对临床观察到的HIV-1突变体表现出高广谱的抗病毒作用。具体来说,化合物30 具有最高的选择性指数(SI = 16094)和最佳的抗逆转录酶能力(IC50 = 39 nM),显示出对WT,K103N的显着抑制活性(EC50 = 13.5、9.4、17.0、52.0和58.2 nM), E138K,L100I,Y181C突变体和对双重突变体的中等活性。这项研究为进一步设计HIV-1抑制剂提供了重要途径。
