Searching for more safe and effective agents for HIV treatments is still an urgent topic worldwide. Based on our continuous modifications on the benzophenone derivatives as HIV-1 reverse transcriptase (RT) inhibitors, a new template bearing N-phenylbenzenesulfonamide (PBSA) structure was designed to enhance the interactions with HIV-1 RT. In this manuscript, a series of PBSA derivatives were synthesized and evaluated for their anti-HIV-1 activity. The preliminary test showed that these compounds were potent to inhibit wild-type HIV-1 with EC50 values ranging of 0.105-14.531 mu mol/L. In particular, compound 13f not only has high anti-HIV-1 activity (0.108 mu mol/L), but also possesses low toxicity with a TI value of 1816.6. Furthermore, the major interactions of the inhibitor 13f with HIV-1 RT were also investigated using the molecular modelling. Our discovered structure-activity relationships (SARs) of these analogues may serve as an important clue for further optimizations. (C) 2014 Yong-Tang Zheng and Xiao-Dong Ma.
