Abstract

Diarylpyrimidine derivatives (DAPYs) exhibit robust anti-HIV-1 potency, although they have been compromised by E138K variant and severe side-effects and been suffering from poor water solubility. In the present work, hydrophilic morpholine or methylsulfonyl and sulfamide-substituted piperazine/piperidines were introduced into the right wing of DAPYs targeting the solvent-exposed tolerant region I. The anti-HIV-1 activities of 11c (EC50(WT) = 0.0035 μM, EC50(E138K) = 0.0075 μM) were the same as and 2-fold better than that of the lead etravirine against the wild-type and E138K mutant HIV-1, respectively, with a relative low cytotoxicity (CC50 ≥ 173 μM). Further test showed a significant improvement in the water solubility of 11c. Besides, 11c displayed no significant inhibition on main Cytochrome P450 enzymes and exhibited no acute/subacute toxicities at doses of 2000 mg·kg-1/50 mg·kg-1 in mice. Taken together, we consider that 11c is a promising lead for further structural optimization.
