Abstract

Human immunodeficiency virus (HIV) reverse transcriptase (RT) associated ribonuclease H (RNase H) remains the only virally encoded enzymatic function not clinically validated as an antiviral target. 2-Hydroxyisoquinoline-1,3-dione (HID) is known to confer active site directed inhibition of divalent metal-dependent enzymatic functions, such as HIV RNase H, integrase (IN) and hepatitis C virus (HCV) NS5B polymerase. We report herein the synthesis and biochemical evaluation of a few C-5, C-6 or C-7 substituted HID subtypes as HIV RNase H inhibitors. Our data indicate that while some of these subtypes inhibited both the RNase H and polymerase (pol) functions of RT, potent and selective RNase H inhibition was achieved with subtypes 8-9 as exemplified with compounds 8c and 9c.

摘要

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)仍然是唯一未在临床上被验证为抗病毒靶点的病毒编码酶功能。已知2-羟基异喹啉-1,3-二酮(HID)可对依赖二价金属的酶功能产生活性位点定向抑制作用,如HIV核糖核酸酶H、整合酶(IN)和丙型肝炎病毒(HCV)NS5B聚合酶。我们在此报告了几种C-5、C-6或C-7取代的HID亚型作为HIV核糖核酸酶H抑制剂的合成及生化评估。我们的数据表明,虽然其中一些亚型同时抑制了RT的核糖核酸酶H和聚合酶(pol)功能,但以化合物8c和9c为例的8-9亚型实现了对核糖核酸酶H的强效和选择性抑制。
