Sider

It contains information on marketed medicines and their recorded adverse drug reactions. The information is extracted from public documents and package inserts. The available information include side effect frequency, drug and side effect classifications as well as links to further information, for example drug–target relations.

ChEMBL

A manually curated chemical database of bioactive molecules with drug-like properties.  In October 2010, ChEMBL version 8 (ChEMBL_08) was launched, with over 2.97 million bioassay measurements covering 636,269 compounds. ChEMBLdb is formatted in a manneramenable to computerized data mining, and attempts to standardize activities between different publications, to enable comparative analysis. ChEMBL is also integrated into other large-scale chemistry resources, including PubChem and the ChemSpider system of the Royal Society of Chemistry.

Therapeutic Targets Database

The Therapeutic Targets Database is a database provides information about the known and explored the rapeutic protein and nucleic acid targets, the targeted disease, pathway information and the corresponding drugs directed at each of these targets.

PharmGKB

The PharmGKB is a comprehensive resource that curates knowledge about the impact of genetic variation on drug response for clinicians and researchers.

PDTD

It is a dual function database that associates an informatics database to a structural database of known and potential drug targets. PDTD is a comprehensive, web-accessible database of drug targets, and focuses on those drug targets with known 3D-structures.
