AB The nonnucleoside reverse transcriptase (RT) inhibitors are structurally
diverse compounds that are specific inhibitors of the human
immunodeficiency virus type 1 RT enzyme. The compounds are largely
functionally identical and bind to a common site in the enzyme. HIV-1
variants that exhibit reduced susceptibility to these inhibitors have
been derived in cell culture and, more recently, from HIV-1-infected
patients undergoing experimental therapy. The variants express amino
acid substitutions at RT positions that apparently interact directly
with the inhibitors. Effects of specific substitutions at these
positions vary among the compounds, suggesting subtle differences in how
the compounds physically interact with the enzyme.
