Exploiting the Tolerant Region I of the Non-Nucleoside Reverse Transcriptase Inhibitor (NNRTI) Binding Pocket: Discovery of Potent Diarylpyrimidine-Typed HIV-1 NNRTIs against Wild-Type and E138K Mutant Virus with Significantly Improved Water Solubility and Favorable Safety Profiles

Diarylpyrimidine derivatives (DAPYs) exhibit robust anti-HIV-1 potency, although they have been compromised by E138K variant and severe side-effects and been suffering from poor water solubility. In the present work, hydrophilic morpholine or methylsulfonyl and sulfamide-substituted piperazine/piperidines were introduced into the right wing of DAPYs targeting the solvent-exposed tolerant region I. The anti-HIV-1
二芳基嘧啶衍生物(DAPYs)表现出强大的抗HIV-1效能,尽管它们已被E138K变体和严重的副作用所损害,并且水溶性差。在本工作中,将亲水性吗啉或甲基磺酰基和磺酰胺取代的哌嗪/哌啶引入了DAPYs的右翼,靶向溶剂暴露的耐受区域I。11c的抗HIV-1活性(EC50(WT)= 0.0035μM ,EC50(E138K)= 0.0075μM)分别与野生型和E138K突变型HIV-1的领先的依那韦林相同,并且是其领先水平的2倍,且细胞毒性相对较低(CC50≥173μM)。进一步的测试表明,11c的水溶性显着提高。除了,11c对小鼠的主要细胞色素P450酶没有明显的抑制作用,并且在2000 mg·kg-1 / 50 mg·kg-1的剂量下也没有急性/亚急性毒性。综上所述,我们认为11c是进一步结构优化的有前途的领先者。
