metal chelation. We report herein the design, synthesis, and biological evaluations of a novel variant of the hydroxypyridonecarboxylic acid scaffold featuring a crucial N-1 benzyl or biarylmethyl moiety. Biochemical studies show that most analogues consistently inhibited HIV RT-associated RNase H in the low micromolar range in the absence of significant inhibition of RT polymerase or IN. One compound showed
将针对临床未经验证的逆转录酶(RT)相关的核糖核酸酶H(RNase H)靶向人类免疫缺陷病毒(HIV)药物发现,通常需要能够在RNase H活性位点螯合两个二价金属离子的化学型。羟基吡啶酮羧酸支架与通过金属螯合抑制同源HIV整合酶(IN)和流感核酸内切酶有关。我们在此报告了以关键氮为特征的羟基吡啶酮羧酸支架的新型变体的设计,合成和生物学评估。-1苄基或联芳基甲基部分。生化研究表明,大多数类似物在不显着抑制RT聚合酶或IN的情况下,始终在低微摩尔范围内抑制HIV RT相关的RNaseH。一种化合物显示出合理的基于细胞的抗病毒活性(EC 50 = 10μM)。对接和晶体学研究证实了与HIV RNase H活性位点的良好结合,为设计更有效的类似物提供了基础。
