Kinase Focused Library

Protein kinases are among the most promising drug targets for anti-cancer treatment. The number of protein kinases encoded by the human genome is enormous, and there are plenty of inhibitors known to date, however, most of them have similar structures and selectivity issues.

The Life Chemicals Protein Kinase Focused Library comprises compounds selected from the Life Chemicals  Stock  Collection of  Small  Molecules for HTS by comparison to known kinase inhibitors. A reference set of 20,000 compounds with known kinase inhibitory activity extracted from ChEMBL database of bioactive molecules has been used for similarity search. Tanimoto similarity index of 0.85 was chosen as a search threshold. At the next stage, the substructure filters for detection and elimination of Pan Assay Interference (PAINS) compounds  have  been  applied.  As  a  result, around 30,000  compounds  were  selected for the Protein  Kinase  Focused Library.
