Abstract

Based on the strategy of molecular hybridization, diketo acid fragment as a classical phamacophore of integrase inhibitors was introduced to reverse transcriptase inhibitors diarylpyrimidines to design a series of diarylpyrimidine-diketo acid hybrids (DAPY-DKAs). The target molecules 10b and 11b showed inhibitory activities against WT HIV-1 with EC50 values of 0.18μM and 0.14μM, respectively. And the results of molecular docking demonstrated the potential binding mode and revealed that the DKA moiety and its ester could both be tolerated in the nonnucleoside binding site (NNBS) of HIV-1 RT.
