Synthesis and biological activity of naphthyl-substituted (B-ring) benzophenone derivatives as novel non-nucleoside HIV-1 reverse transcriptase inhibitors.

摘要

A novel series of benzophenone derivatives with B-ring substituted by naphthyl ring has been synthesized and evaluated as non-nucleoside HIV-1 reverse transcriptase inhibitors. Most of these compounds showed good to moderate activity against wild-type HIV-1 and mutated viruses. In particular, the analogue 10i demonstrated the most potent activity against wild-type HIV-1 with an EC value of 4.8 nM, and with a high selectivity index up to 10347.9, it also proved to be active against the HIV-1 double mutant strain A (K103N+Y181C) with an EC value of 2.1 muM. In addition, the molecular modeling study was used to explore the major interactions between the potent inhibitors with the HIV-1 RT. The investigation of the structure-activity relationships may serve as an important lead for the further optimization.
