Human immunodeficiency virus (HIV) reverse transcriptase (RT)-associated ribonuclease H (RNase H) remains an unvalidated drug target. Reported HIV RNase H inhibitors generally lack significant antiviral activity. We report herein the design, synthesis, biochemical and antiviral evaluations of a new 6-biphenylmethyl subtype of the 3-hydroxypyrimidine-2,4-dione (HPD) chemotype. In biochemical assays
人类免疫缺陷病毒(HIV)逆转录酶(RT)相关的核糖核酸酶H(RNase H)仍然是未经验证的药物靶标。据报道,HIV RNase H抑制剂通常缺乏显着的抗病毒活性。我们在此报告了3-羟基嘧啶-2,4-二酮(HPD)化学型的新的6-联苯甲基亚型的设计,合成,生化和抗病毒评估。在生化分析中,这种新亚型的类似物可在低纳摩尔范围内有效抑制RT RNase H,而在测试的最高浓度下却不会抑制RT聚合酶(pol)或整合酶链转移(INST)。在基于细胞的测定中,一些类似物在低微摩尔范围内抑制HIV,浓度高达100μM,却没有细胞毒性。
