Abstract
Introduction: This report proposes the application of a new Machine Learning algorithm
called Fuzzy Unordered Rules Induction Algorithm (FURIA)-C in the classification of druglike
compounds with antidiabetic inhibitory ability toward the main two pharmacological targets:
α-amylase and α-glucosidase.
Methods: The two obtained QSAR models were tested for classification capability, achieving satisfactory
accuracy scores of 94.5% and 96.5%, respectively. Another important outcome was to
achieve various α-amylase and α-glucosidase fuzzy rules with high Certainty Factor values. Fuzzyrules
derived from the training series and active classification rules were interpreted. An important
external validation step, comparing our method with those previously reported, was also included.
Results: The Holm’s test comparison showed significant differences (p-value<0.05) between
FURIA-C, Linear Discriminating Analysis (LDA), and Bayesian Networks, the former beating the
two latter according to the relative ranking score of the Holm’s test.
Conclusion: From these results, the FURIA-C algorithm could be used as a cutting-edge technique
to predict (classify or screen) the α-amylase and α-glucosidase inhibitory activity of new compounds
and hence speed up the discovery of new potent multi-target antidiabetic agents.
