A novel series of 3-benzyloxy-linked pyrimidinylphenylamine derivatives (8a-8s) was designed, synthesized and evaluated for their in vitro anti-HIV activity in MT-4 cell cultures. Most of the compounds inhibited wild-type (wt) HIV-1 replication in the lower micromolar concentration range (EC50 = 0.05-35 mu M) with high selectivity index (SI) values (ranged from 10 to >4870). In particular, 8h and 8g displayed excellent antiretroviral activity against wt HIV-1 with low cytotoxicity (EC50 = 0.07 mu M, CC50 >347 mu M, SI >4870; EC50 = 0.05 mu M, CC50 = 42 mu M, SI = 777, respectively), comparable to that of the marked drug nevirapine (EC50 = 0.113 mu M, CC50 >15 mu M, SI >133). In order to confirm the binding target, 8h was selected to perform the anti-HIV-1 RT assay. Additionally, preliminary structure activity relationship (SAR) analysis and molecular docking studies of newly synthesized compounds were also discussed, as well as the predicted physicochemical properties.
