Human Ion Channels Annotated Library
Description
• Physiologically the Ion Channels are regulated by
– voltage, e.g. most Na, K, Ca and some Cl channels are “voltage-gated ion channels”– intracellular and/or extracellular mediators, e.g. some K and Cl channels, TRP channels, GABA(A) andP2X receptors are “ligand-gated ion channels”
– the central nervous system (CNS), e.g. sleep disorders, anxiety, epilepsy, pain– the peripheral nervous system, e.g. anticonvulsant, analgesic, anti-inflammatory– the cardiovascular system, e.g. ischemia, hypoxic conditions, stroke
❑ Annotated activities : 86 ion channels targets❑ Express Delivery : 320 compounds❑ Complete Version : 394 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
