Therapeutic Targets Database
BIDD Pharmainformatics Databases

Because of funding problem, we tentatively have this 2014 version of TTD available for quick access. We are trying to put the latest version back on this website. In the meantime, an alternative site of the latest version of TTD can be accessed HERE, which may be slow to access at some times.

We value and appreciate your support. If you want to support our effort in seeking funding, please send your support letter to

Therapeutic Target Database

A database to provide information about the known and explored therapeutic protein and nucleic acid targets, the targeted disease, pathway information and the corresponding drugs directed at each of these targets. Also included in this database are links to relevant databases containing information about target function, sequence, 3D structure, ligand binding properties, enzyme nomenclature and drug structure, therapeutic class, clinical development status. All information provided are fully referenced.

Statistics of this database

This database currently contains 2,360 targets, including 388 successful, 461 clinical trial, 44 discontinued and 1,331 research targets, 20,667 drugs, including 2,003 approved, 3,147 clinical trial, 14,853 experimental drugs (14,170 small molecules and 652 antisense drugs with available strucuture or oligonucleotide sequence).

The database incorporates the ICD-10-CM and ICD-9-CM codes of the International Classification of Diseases (covering 897 disease conditions, 893 targets, and 5,697 drugs), and also contains biomarkers (1,755 biomarkers for 365 disease conditions), drug scaffolds (210 scaffolds for 714 drugs and leads), 1,008 nature-derived agents, 20818 multi-target agents against 385 target-pairs, and the activity data of 1,436 agents against 297 cell-lines. .
