4,1-Benzoxazepinone analogues of efavirenz (Sustiva™) as HIV-1 reverse transcriptase inhibitors
摘要:
A series of 4,1-benzoxazepinone analogues of efavirenz (Sustiva(TM)) as potent NNRTIs has been discovered. The cis-3-alkylbenzoxazepinones are more potent then the trans isomers and can be synthesized preferentially by a novel stereoselective cyclization. The best compounds are potent orally bioavailable inhibitors of both wild-type HIV-1 and its clinically relevant K103N mutant virus, but are highly protein-bound in human plasma.
