Recent Advances in the Research of 2,3-Diaryl-1,3-thiazolidin-4-one Derivatives as Potent HIV-1 Non-nucleoside Reverse Transcriptase Inhibitors

Derived from the structure of 1H,3H-thiazolo[3,4-a]benzimidazoles (TBZs), 2,3-diaryl-1,3-thiazolidin-4-one derivatives became a novel class of HIV-1 non-nucleoside reverse transcriptase inhibitors (NNRTIs). Under the guidance of continuous structure-activity relationship (SAR) analysis and molecular modeling, various structural modifications were carried out on nearly all the positions of the thiazolidin-4-one nucleus. Some of the derivatives proved to be highly effective against HIV-1 replication at 10-40 nanomolar concentration ranges with minimal cytotoxicities. In this article, the whole development of 2,3-diaryl-1,3-thiazolidin-4-one series from the discoveries to recent advances, their panoramic SAR studies and binding modes based on molecular modeling were reviewed, and also some enlightenments for further investigation were presented.
