Description


•Phosphatases are enzymatic proteins that dephosphorylate other functional proteins

•Physiologically the phosphatases enzymatic activity can be modulated by
-Catalytic phosphate site binders
-Allosteric binders that cause conformational changes within the catalytic site

•Phosphatases are interesting therapeutic targets for

-Oncology, e.g. cancer immunotherapy
-Metabolic diseases, e.g. diabetes, obesity
-Infections, e.g. antibacterial, antiviral


A unique collection of small molecule compounds with annotated activities for Phosphatases protein targets

  • Annotated activities : 25 phosphatase targets
  • Express Delivery : 160 compounds
  • Complete Version : 225 compounds

Library Composition

Data sources of annotations : Pharos, ChEMBL 25, PubChem, PubMed, Current Patent Literature (CAS, Integrity)

IDNUMBER – ChemDiv Catalog ID (in some instances the same IDNUMBER might have multiple annotation entries due to multiple data sources or because having activity against multiple similar targets);

UNIPROT – SwissProt and ChEMBL Target accesion ID; 

Type – character of the measured activity;

Value – Active compounds selection criteria, included only compounds with reported activities < 5 µM;

pubmed_id – PubMed record entry; 

doi, patent_id – journal or patent reference to a publication of original data;  

For screening data extracted from PubChem, see column assay_description for entry names PUBCHEM_BIOASSAY
