The outbreak of 2019 novel coronavirus (COVID-19) has caused serious threat to public health Discovery of new anti-COVID-19 drugs is urgently needed Fortunately, the crystal structure of COVID-19 3CL proteinase was recently resolved The proteinase has been identified as a promising target for drug discovery in this crisis Here, a dataset including 2030 natural compounds was screened and refined based on the machine learning and molecular docking The performance of six machine learning (ML) methods of predicting active coronavirus inhibitors had achieved satisfactory accuracy, especially, the AUC (Area Under ROC Curve) scores with fivefold cross-validation of Logistic Regression (LR) reached up to 0 976 Comprehensive ML prediction and molecular docking results accounted for the compound Rutin, which was approved by NMPA (National Medical Products Administration), exhibited the best AUC and the most promising binding affinity compared to other compounds Therefore, Rutin might be a promising agent in anti-COVID-19 drugs development © Copyright © 2020 Xu, Yang, Zhang, Zhang, Yang, Liu, Wei and Liu
