Introduction: Thus, the therapeutic efficacy of
NNRTIs is mainly restricted due to development of viral resistance to
NNRTIs associated with mutations that include
K103N,
L100I and
Y188L, and with the development of second generation
NNRTIs, the search for a more suitable
NNRTI, which blocks the replication of all existing resistant viral strains and retains potency for longer periods of time by modifying the existing drug classes or by incorporating appropriate substitutions in the newer chemical scaffolds, according to the pharmacophoric requirements using multi-disciplinary approaches is the call of the day.
