DrugBank

Description: A comprehensive, free-to-access, online database containing information on drugs and drug targets. As both a bioinformatics and a cheminformatics resource, we combine detailed drug (i.e. chemical, pharmacological and pharmaceutical) data with comprehensive drug target (i.e. sequence, structure, and pathway) information
