摘要
In order to improve the positional adaptability of our previously reported naphthyl diaryltriazines(NP-DATAs),synthesis of a series of novel biphenyl-substituted diaryltriazines(BP-DATAs)with a flexible side chain attached at the C-6 position is presented.These compounds exhibited excellent potency against wild-type(WT)HIV-1 with EC50 values ranging from 2.6 to 39 nmol/L and most of them showed low nanomolar anti-viral potency against a panel of HIV-1 mutant strains.Compounds 5 j and 6 k had the best activity against WT,single and double HIV-1 mutants and reverse transcriptase(RT)enzyme comparable to two reference drugs(EFV and ETR)and our lead compound NP-DATA(1).Molecular modeling disclosed that the side chain at the C-6 position of DATAs occupied the entrance channel of the HIV-1 reverse transcriptase non-nucleoside binding pocket(NNIBP)attributing to the improved activity.The preliminary structure-activity relationship and PK profiles were also discussed.
