In the current study, twenty-two compounds based upon 3-hydroxy-3-(2-oxo-2-phenylethyl)indolin-2-one nucleus were designed, synthesized and in vitro evaluated for HIV-1 RT inhibition and anti-HIV-1 activity. Compounds 3d, 5c and 5e demonstrated encouraging potency against RT enzyme as well as HIV-1 in low micromolar to nanomolar concentration with good to excellent safety index. Structure activity
在本研究中,设计,合成了22种基于3-羟基-3-(2-氧代-2-苯基乙基)吲哚-2-酮核的化合物,并在体外评估了其对HIV-1 RT的抑制作用和抗HIV的作用。 -1活动。化合物3d,5c和5e在低微摩尔至纳摩尔浓度下显示出令人鼓舞的针对RT酶和HIV-1的效力,并具有良好至极佳的安全指数。结构活性关系研究表明,在羟吲哚环第5位的卤素(如溴或氯)显着提高了对RT的效力。此外,在苯环邻位的甲氧基或氯基团也显着有利于RT抑制活性。七种化合物(3b,3c,3d,3e,5b,5c和5e)对突变的HIV-1 K103N菌株测试了具有更好抗HIV-1效力的药物。通过对接研究对推定的结合模式以及最佳活性化合物5c与野生HIV-1 RT的相互作用模式进行了研究。
