ABSTRACT
To enhance the anti-HIV-1 efficacy and solubility of our previously documented NNRTI 1, a collection of innovative quinoline-substituted DAPY derivatives were devised using heteroaromatic replacement strategy. The results of biological evaluation revealed that the representative compound 5h possessed the highest inhibitory activity against wild-type HIV-1 and selectivity index (EC50 = 0.0018 µM, SI > 166667), which were obviously better than that of 1 (EC50 = 0.00978 µM, SI > 37764), NVP (EC50 = 0.059 µM, SI > 158), EFV (EC50 = 0.028 µM, SI > 269), and ETR (EC50 = 0.0029 µM, SI > 1519). The water solubility of compound 5h was remarkably improved, surpassing that of 1, ETR and RPV. Additionally, this compound exerted significantly enhanced anti-resistance potency, compared to 1, and displayed comparable activity to ETR against WT RT of HIV-1 (IC50 = 0.011 µM). To elucidate the underlying molecular mechanisms, molecular docking studies were conducted to investigate the crucial interactions between 5h and WT/mutant strains of HIV-1. These findings provide valuable insights and drive further advancements in the development of DAPYs for HIV therapy.
