Ligand Activity Visualisation Charts

These are box plot that provide a unique visualisation, summarising all the activity data for a ligand taken from ChEMBL and GtoPdb across multiple targets and species. Click on a plot to see the median, interquartile range, low and high data points. A value of zero indicates that no data are available. A separate chart is created for each target, and where possible the algorithm tries to merge ChEMBL and GtoPdb targets by matching them on name and UniProt accession, for each available species. However, please note that inconsistency in naming of targets may lead to data for the same target being reported across multiple charts.

SMILES / InChI / InChIKey

SMILES (Simplified Molecular Input Line Entry Specification) A specification for unambiguously describing the structure of chemical molecules using short ASCII strings. Canonical SMILES specify a unique representation of the 2D structure without chiral or isotopic specifications. Isomeric SMILES include chiral specification and isotopes.

Standard InChI (IUPAC International Chemical Identifier) and InChIKey InChI is a non-proprietary, standard, textual identifier for chemical substances designed to facilitate linking of information and database searching. An InChIKey is a simplified version of a full InChI, designed for easier web searching.

Target Comment
ABCC4 Although reported to facilitate cellular cyclic nucleotide export, this role has been questioned [4]; reported to export prostaglandins in a manner sensitive to NSAIDS [17]. A common binding site accommodates substrates including PGE1, PGE2 and dehydroepiandrosterone sulphate (DHEAS) [16].
mPGES2 Heme-free mPGES2 catalyses the isomerisation of prostaglandin H2 (PGE2) to prostaglandin E2 (PGE2) in the presence of glutathione (GSH); in contrast heme-bound mPGES2 catalyses the degradation of PGH2 to 12-hydroxyheptadecatrienoic acid (HHT) and malondialdehyde (MDA) [24,28-29]. In colon cancer cells artemisinin has been reported to bind reversibly to mPGES2 (occupying the PGH2 site), with the effect of blocking PGE2 biosynthesis and inhibiting cell proliferation [6].
