A series of novel S-DABO analogues (4a1–5a12) have been synthesized by an efficient method and evaluated as inhibitors of human immunodeficiency virus type-1 (HIV-1). The biological testing results clearly indicated that the substitution of halogen at the C5 position of pyrimidine ring could increase the anti-HIV-1 RT activity. The most active compounds showed activity in the low micromole range with
已经通过一种有效的方法合成了一系列新颖的S -DABO类似物(4a1 – 5a12),并被评估为1型人类免疫缺陷病毒(HIV-1)的抑制剂。生物学测试结果清楚地表明,在嘧啶环的C5位取代卤素可以提高抗HIV-1 RT的活性。最具活性的化合物在低微摩尔范围内表现出活性,其IC 50值(IC 50 0.18–3.03μM)与奈韦拉平(IC 50 4.12μM)相当。对接表明,HIV-1 RT中TYR188的卤素和羰基之间形成了新的卤素键。
