摘要
Serial passage of human immunodeficiency virus type 1 in MT-2 cells in increasing concentrations of the D-and L-enantiomers of beta-2',3'-didehydro-2',3'-dideoxy-5-fluorocytidine (d4FC) resulted in the selection of viral variants with reverse transcriptase substitutions M184I or M184V for L-d4FC and I63L, K65R, K70N, K70E, or R172K for D-d4FC. Phenotypic analysis of site-directed mutants defined the role of these mutations in reducing susceptibility to L- or D-d4FC.
