interface. Encouraging improvements in anti-resistance efficacy were observed in some of these analogs, with the most promising compound 7 g being 3 to 26 − fold more potent than 3 against five mutant strains (E138K, Y181C, L100I, K103N, and Y188L). This analog surpassed the activity and selectivity of compound 3 by approximately 2-fold (EC50 = 0.007468 μM, SI = 4260). Furthermore, it was found to demonstrate
我们最近对开发用于 HIV 治疗的 1-[(2-羟基乙氧基)甲基]-6-(苯硫基)胸腺嘧啶 (HEPT) 类似物产生了极大的兴趣,确定了一种有效的非核苷逆转录酶抑制剂 (NNRTI) 3 (EC 50 = 0.01681 μM ) ,但其治疗效果因其较差的抗耐药性而受到限制。这促使我们寻找具有广谱活性的潜在 HEPT 类似物,通过探索溶剂-蛋白质界面的化学空间,产生了一系列新型 HEPT 类似物。在其中一些类似物中观察到抗耐药性功效的令人鼓舞的改进,其中最有前途的化合物7 g对抗五种突变菌株(E138K、Y181C、L100I、K103N 和 Y188L)的 效力比3强3 至 26 倍 。该类似物的活性和选择性超过化合物3约 2 倍(EC 50 = 0.007468 μM,SI = 4260)。此外,还发现其在体外对 CYP 和 hERG 的抑制作用很弱,并且在体内没有急性毒性。本研究
