title: Replacement of the metabolically labile methyl esters in the alkenyldiarylmethane series of non-nucleoside reverse transcriptase inhibitors with isoxazolone, isoxazole, oxazolone, or cyano substituents.
abstract: The alkenyldiarylmethanes (ADAMs) are a unique class of non-nucleoside reverse transcriptase inhibitors that have potential value in the treatment of HIV/AIDS. However, the potential usefulness of the ADAMs is limited by the presence of metabolically labile methyl ester moieties. A series of novel ADAMs were therefore designed and synthesized in order to replace the metabolically labile methyl ester moieties of the existing ADAM lead compounds with hydrolytically stable, fused isoxazolone, isoxazole, oxazolone, or cyano substituents on the aromatic rings. The methyl ester and methoxy substituents on both of the aromatic rings in the parent compound 1 were successfully replaced with metabolically stable moieties with retention of anti-HIV activity and a general decrease in cytotoxicity.
