Abstract(in English) The clearance pathway is one of the important factors to consider the pharmacokinetics of drugs. We have developed a machine learning system of drug clearance pathway for a given drug compound from its physicochemical descriptors. The system is composed of five support vector machines (SVMs), each corresponding to one of five major candidate clearance pathways, and prediction is given by choosing a pathway with largest SVM output. We prepared pathway data for 157 drugs, and 1089 physicochemical descriptors for each of them. However, if we use all the descriptors, we will have over-learning problem and less explainable model. Thus we performed exhaustive feature selection procedure, by a modified greedy algorithm or a correlation coefficient-based method, and our system showed more than 85% prediction accuracy when using 12 selected descriptors.
