GtoPdb Ligand ID: 8577

Synonyms: GSK 484 | GSK-484
Compound class: Synthetic organic
Comment: GSK484 binds to peptidyl arginine deiminase, type IV (PADI4; Q9UM07) and inhibits its activity [1]. PADI4 contributes to regulating the histone code by effecting the citrullination/deimination of histones. PADI4 has strong associations with cancer and immune and inflammatory processes. GSK484 will be a useful tool to enhance understanding of the normal and pathological functions of PADI4.
This is a compound from the Structural Genomics Consortium's (SGC) Epigenetics Probes Collection, developed in collaboration with GlaxoSmithKline (GSK).

2D Structure

An image of the ligand's 2D structure. For small molecules with SMILES these are drawn using the NCI/CADD Chemical Identifier Resolver. Click on the image to access the chemical structure search tool with the ligand pre-loaded in the structure editor. For other types of ligands, e.g. longer nucleotides and peptides, a manually drawn representation of the molecule may be provided.

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.

Bioactivity Comments
GSK484 binds to PADI4 reversibly and is substrate-competitive, with an IC50 of 50 nM in the absence of calcium (250nM @ 2mM calcium) [1]. The phramacodynamic and pharmacokinetic profiles of GSK484 suggest that has potential as an in vivo tool.
