AB To evaluate the potential that multiply resistant human immunodeficiency
virus type 1 variants may arise during combination nucleoside and
nonnucleoside reverse transcriptase inhibitor therapy, we constructed a
series of mutant reverse transcriptase enzymes and viruses that
coexpressed various combinations of resistance-associated amino acid
substitutions. Substitutions at residues 100 (Leu-->Ile) and 181
(Tyr-->Cys), which mediate resistance to the nonnucleosides, suppressed
resistance to 3'-azido-3'-deoxythymidine (AZT) when coexpressed with
AZT-specific substitutions. However, a number of viral variants that
exhibited significantly reduced susceptibilities to both classes of
inhibitors were constructed.
