studies aimed at developing new potential anti-AIDS drug candidates have focused on the design and synthesis of new DCK analogs with improved molecular water solubility. Based on the structures and biodata of previous DCK analogs, 3D-QSAR studies have been performed which resulted in two reliable computational models, CoMFA and CoMSIA, with r(2) values of 0.995 and 0.987, and q(2) values of 0.662 and 0
我们当前的研究旨在开发新的潜在抗艾滋病药物候选者,重点在于设计和合成具有改善的分子水溶性的新型DCK类似物。根据以前的DCK类似物的结构和生物数据,进行了3D-QSAR研究,得出了两个可靠的计算模型:CoMFA和CoMSIA,r(2)值为0.995和0.987,q(2)值为0.662和分别为0.657。根据这些3D-QSAR模型,随后设计,合成了15个在3位带有极性官能团的DCK类似物,并针对H9和MT4细胞系中的HIV-1复制进行了评估。新的DCK类似物3b,3c,4b,4c,6a,7c和9a在两种测定中均显示出有前途的效价,EC(50)值范围为0.09至0.0002 microM。同时,这些有前途的化合物还显示出从0.90至5.19的广泛预测logP值,这增加了从此类化合物中鉴定抗HIV药物候选物进行临床试验的可能性。此外,实验值和预测值都很好地匹配,从而证实了已建立的3D-QSAR模型的可靠性。
