Abstract

SG-1 was previously identified as a potent Non-nucleoside reverse transcriptase inhibitors (NNRTI) which works through inhibition of reverse transcriptase (RT) RNA-dependent DNA polymerase activity via a direct binding event. To further investigate the relationship between its structure and activity, four series of novel analogues were designed and synthesized with 12 of them inhibiting HIV-1 replication with IC50s in the range 0.09-6.71 μM. Compound 4b, 4c, 4f, 2 and 6b were further tested on two NNRTI-resistant HIV-1 strains and one NNRTI-resistant superbug. The result showed that RT- E138K/M184V mutant virus conferred 4.7-9.1-fold resistance to 4c, 4f, 2 and 6b, but only showed slight resistance to 4b (2-fold) which was better than SG-1.

Keywords: HIV; NNRTI-resistant; NNRTIs; SG-1; Structure-activity relationship.
