I am looking for a database/API to map ''Target ChEMBL ID" to "Entrez Gene". For example, given CHEMBL6196 I would like to get 7363 (UGT2B4).
How about "Molecule ChEMBL ID" to "DrugBank Id", e.g. 'CHEMBL1256957': 'DB00264'?
Currently, I have to do this manually by searching for each ID in www.ebi.ac.uk/chembl.
