GtoPdb Ligand ID: 9960

Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: This compound 3 is a lead chemical scaffold for the further development of lysine demethylase 6B (KDM6B, also known as JMJD3 and Jumonji D3) inhibitors. JMJD3 is an inducible enzyme, that along with ubiquitously transcribed X chromosome tetratricopeptide repeat protein (UTX), forms the KDM6 subfamily of histone modifying enzymes, which catalyze the demethylation of lysine 27 on histone H3 (H3K27). H3K27 demethylases are involved in maintaining the epigenetic transcriptional state in replicating and postmitotic cells. Prior to the discovery of compound 3, GSK-J1 and its derivatives were the only selective KDM6 inhibitors to be reported [5-6]. Compound 3 is suitable for investigating the role of JMJD3 in normal tissues and in tissues that are altered by pathological conditions, such as cancer and inflammation.

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.

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.
