Glucagon-like peptide 1 receptor (GLP-1R) is a well-known drug target for the treatment of type 2 diabetes mellitus (T2DM). However, the currently marketed peptidyl GLP-1R agonist drugs are restricted by the requirement of injection. Hence, there is a continued need to develop orally bioavailable small molecule GLP-1R agonist drugs that could be beneficial for the treatment of T2DM. In this study, we report a new strategy to predict small molecule GLP-1R agonists with machine learning approach. Several regression and classification models were built based on support vector machine algorithm and diverse compounds with molecular properties and structural fingerprints as descriptors. For regression models, the ten-fold cross-validation squared correlation coefficient (q2, for training sets) and determination coefficient (r2, for test sets) of the optimized models were greater than 0.6, respectively. For classification models, the overall predictive accuracies were around or over 90% (for test sets). The results demonstrated that these reliable models could be used to identify highly active agonists for the purpose of virtual screening. The important properties and structural fragments for GLP-1R agonists derived from these models can be used for the novel GLP-1R agonist scaffold design.
