Combining DFT and QSAR result for predicting the biological activity of the phenylsuccinimide derivatives
ABSTRACT:
Study 3D-QSAR is
applied to a set of 57 molecules based on N-phenylsuccinimides using the
principal component analysis (PCA) method, the multiple linear regression
method (MLR) and the artificial neural network (ANN). The predicted values of activities
are in good agreement with the experimental results. The artificial neural
network (ANN) techniques, considering the relevant descriptors obtained from
the MLR, showed a correlation coefficient of 0,9 with an 8-20-1 ANN model which
is a good result. As a result of quantitative structure-activity relationships,
we found that the model proposed in this study is constituted of major
descriptors used to describe these molecules. The obtained results suggested
that proposed combination of several calculated parameters could be useful in
predicting biological activity of N-phenylsuccinimides derivatives.
