Development of Quantitative Structure–Anti-Inflammatory Relationships of Alkaloids
Published 2024-11-01“…Molecules were properly curated, and the molecular geometries of the compounds were optimized using the semi-empirical method (PM3) to calculate molecular descriptors, binary fingerprints (extended-connectivity fingerprints and path fingerprints) and MACCS (Molecular ACCess System) structural keys. Then, we calibrated the QSAR models using well-known linear and non-linear machine learning classifiers, i.e., partial least squares discriminant analysis (PLSDA), random forests (RF), adaptive boosting (AdaBoost), <i>k</i>-nearest neighbors (<i>k</i>NN), <i>N</i>-nearest neighbors (N3) and binned nearest neighbors (BNN). …”
