Database molecules

The database contains a total of 190,000 small molecules, which are divided into 23 sub libraries. Each sub library focuses on a specific target or target class. These targets include enzymes such as aminoacyltransferases, hydrolases, isomerases, kinases, ligases, lyases, oxidoreductases, phosphatases, proteases, transferases, and phosphodiesterases. It also includes membrane receptors such as βAmyloid A4 protein, Family A GPCR, Family B GPCR, Family C GPCR, Frizzled family GPCR, Taste family GPCR, σOpioid receptor, and Thrombopoietin receptor. Additionally, there are ion channels (voltage-gated and ligand-gated) and an epigenetic regulator.

This library is based on ChemDiv’s database of molecules, which are annotated by target or target class and activity. The activity annotation follows the ChEMBL hierarchy, with activities of ≤10 μM. The library encompasses over 800,000 molecules and 6 million activity records. The selection of target classes included in the library is based on statistically significant numbers of active molecules within each class.
