A novel series of dihydroquinazolin-2-amine derivatives were synthesized and evaluated for their anti-HIV-1 activity in MT-4 cell cultures. All of the molecules were active against wild-type HIV-1 with EC50 values ranging from 0.61 μM to 0.84 nM. The most potent inhibitor, compound 4b, had an EC50 value of 0.84 nM against HIV-1 strain IIIB, and thus was more active than the reference drugs efavirenz
合成了一系列新的二氢喹唑啉-2-胺衍生物,并评估了它们在MT-4细胞培养物中的抗-HIV-1活性。所有分子均具有抗野生型HIV-1的活性,EC 50值为0.61μM至0.84 nM。最有效的抑制剂化合物4b对HIV-1株IIIB的EC 50值为0.84 nM,因此比参考药物依非韦伦和依曲韦林更有活性。此外,大多数化合物对带有逆转录酶(RT)E138K突变的菌株保持高活性(低微摩尔EC 50值)。化合物4b的EC 50对于带有RT E138K和RES056突变的非核苷类逆转录酶抑制剂耐药菌株,其抗药性值分别为3.5 nM和66 nM。在酶活性测定中,化合物4b对HIV-1 RT的IC 50值为10 nM。初步的SAR和分子对接研究为进一步优化提供了宝贵的见解。
