| Aim: Pyridinone derivatives have high potency against non-nucleoside reverse
transcriptase inhibitor (NNRTI)-resistant human immunodefciency virus type-1 strains.
Quantitative structure–activity relationship (QSAR) studies on a series of pyridinone
derivatives acting as NNRTIs are very important in designing the next generation
of NNRTIs. Methodology & results: The QSAR models were developed using linear
(single and forward stepwise) and combined nonlinear artifcial neural network
(ANN) approaches. ANN provided QSAR model with highly correlating values of 0.963,
0.964, 0.920 and 0.917, corresponding to the biological activity pIC50 of the training,
validation, testing and all samples, respectively. Conclusion: The nonlinear ANN-QSAR
model based on the topological polarizability, geometrical steric, hydrophobicity and
substituted benzene functional group indices might be able to help for designing
novel pyridinone NNRTIs. |
