The DrugBank database available at the University of Alberta is a unique bioinformatics and cheminformatics resource that combines detailed drug (i. The University of Alberta (U of A is a public research University located in Edmonton, Alberta, Canada. Bioinformatics is the application of information technology to the field of molecular biology Cheminformatics (also known as chemoinformatics and chemical informatics) is the use of computer and informational techniques applied to a range of problems e. chemical, pharmacological and pharmaceutical) data with comprehensive drug target (i. e. sequence, structure, pathway) information. [1] The database contains nearly 4800 drug entries including >1480 FDA-approved small molecule drugs, 128 FDA-approved biotech (protein/peptide) drugs, >71 nutraceuticals and >3200 experimental drugs. Additionally, more than 2500 protein (i. e. drug target, non-redundant) sequences are linked to these drug entries. Each DrugCard entry contains more than 100 data fields with half of the information being devoted to drug/chemical data and the other half devoted to drug target or protein data. Users may query DrugBank in any number of ways. It is maintained by David Wishart and Craig Knox.
