A novel series of etravirine-VRX-480773 hybrids were designed using structure-guided molecular hybridization strategy and fusing the pharmacophore templates of etravirine and VRX-480773. The anti-HIV-1 activity and cytotoxicity was evaluated in MT-4 cell cultures. The most active hybrid compound in this series, N-(2-chlorophenyl)-2-((4-(4-cyano-2,6-dimethylphenoxy) pyrimidin-2-yl) thio) acetamide 3d (EC50 = 0.24, SI > 1225), was more potent than delavirdine (EC50 = 0.66 mu M, SI > 67) in the anti-HIV-1 in vitro cellular assay. Studies of structure-activity relationships established a correlation between anti-HIV activity and the substitution pattern of the acetanilide group. (C) 2015 Elsevier Ltd. All rights reserved.
