In vitro selection of mutations in the human immunodeficiency virus type 1 reverse transcriptase that decrease susceptibility to (-)-beta-D-dioxolane-guanosine and suppress resistance to 3'-azido-3'-deoxythymidine.


Human immunodeficiency virus type 1 (HIV-1) isolates resistant to (-)-beta-D-dioxolane-guanosine (DXG), a potent and selective nucleoside analog HIV-1 reverse transcriptase (RT) inhibitor, were selected by serial passage of HIV-1(LAI) in increasing drug concentrations (maximum concentration, 30 microM). Two independent selection experiments were performed… (More)
