identification and optimization of novel non-nucleoside reverse transcriptase inhibitors (NNRTIs), we have employed a structure-based bioisosterism strategy, with which a new series of diarylpyridazine (DAPD) derivatives were synthesized and evaluated for their anti-HIV-1 (human immunodeficiency virus type 1) activity. Most of the title compounds displayed excellent anti-HIV-1 activity at submicromolar concentrations
在继续努力确定和优化新型非核苷类逆转录酶抑制剂(NNRTIs)的过程中,我们采用了基于结构的生物立体异构策略,合成了一系列新的二芳基哒嗪(DAPD)衍生物,并评估了它们的抗HIV-1(人类免疫缺陷病毒1型)活性。大多数标题化合物在34 nM至5.08μM的亚微摩尔浓度下均表现出出色的抗HIV-1活性。最有前途的化合物8g以低EC 50值(0.034μM)抑制MT-4细胞中的HIV-1 IIIB,低于参考药物奈韦拉平和地拉夫定。通过对接模拟讨论并合理化了结构活动关系(SAR)。
