Abstract

Based on molecular simulation, the etravirine–VRX-480773 hybrids previously disclosed by our group were optimized to yield novel pyrimidine sulfonylacetanilides 8 with improved activity against a panel of seven clinically relevant single and double mutant strains of HIV-1. The improvement in potency in this in vitro model of HIV RNA replication partly validates the mechanism by which this class of allosteric pyrimidine derivatives inhibits the reverse transcriptase (RT), and represents a remarkable step forward in the development of anti-HIV drugs.
