Protein Kinase Inhibitors’ Classification Using K-Nearest Neighbor Algorithm
2020
Abstract Protein kinases are enzymes acting as a source of phosphate through ATP to regulate protein biological activities by phosphorylating groups of specific amino acids. For that reason, inhibiting protein kinases with an active small molecule plays a significant role in cancer treatment. To achieve this aim, computational drug design, especially QSAR model, is one of the best economical approaches to reduce time and save in costs. In this respect, active inhibitors are attempted to be distinguished from inactive ones using hybrid QSAR model. Therefore, genetic algorithm and K-Nearest Neighbor method were suggested as a dimensional reduction and classification model, respectively. Finally, to evaluate the proposed model’s performance, support vector machine and Naive Bayesian algorithm were examined. The outputs of the proposed model demonstrated significant superiority to other QSAR models.
