Computer-Aided Design, Synthesis and Validation of 2-Phenylquinazolinone Fragments as CDK9 Inhibitors with Anti-HIV-1 Tat-Mediated Transcription Activity
The activity of the cyclin‐dependent kinase 9 (CDK9) is critical for HIV‐1 Tat‐mediated transcription and represents a promising target for antiviral therapy. Here we present computational studies that, along with preliminary synthetic efforts, allowed us to identify and characterize a new class of nontoxic anti‐CDK9 chemotypes based on the 2‐phenylquinazolinone scaffold. Inhibition of CDK9 translated
细胞周期蛋白依赖性激酶9(CDK9)的活性对于HIV-1 Tat介导的转录至关重要,是抗病毒治疗的有希望的靶标。在这里,我们介绍了计算研究,以及初步的合成努力,使我们能够鉴定和表征基于2-苯基喹唑啉酮骨架的新型无毒抗CDK9化学型。对CDK9的抑制转化为选择性干扰Tat介导的病毒启动子反式激活的能力以及对潜伏感染细胞中HIV-1激活的抑制的能力,其中最有效的衍生物37(2-(4-氨基苯基)-7-氯喹唑啉-4(3 H ^) -酮)示出IC 50为4.0μ值中号。由于本文报道的2-苯基喹唑啉酮仅仅是片段,因此它们在很大程度上是可优化的,从而为开发具有更高效能的衍生物铺平了道路。
