PDB Ligand
Compound class: Synthetic organic
Comment: Laduviglusib (CHIR-99021) is an ATP-competitive inhibitor of glycogen synthase kinase-3α and β (GSK-3α/β), equipotent at both isozymes [8]. The chemical structure of CHIR-99021 matches that submitted to the WHO for the INN laduviglusib. GSK-3β has been implicated in multiple human disorders, by influencing a number of significant cellular pathways (including insulin signalling and glycogen synthesis, neurotrophic factor signalling, Wnt signalling, neurotransmitter signalling and microtubule dynamics) [1]. CHIR-99021 acts as a functional Wnt pathway activator [2,10].
Zaki syndrome, a rare disorder of embryonic organ development in humans, can arise due to homozygous mutations in the Wnt ligand secretion mediator gene (WLS) [4]. CHIR-99021 has been used in a mouse model of Zaki syndrome to demonstrate that activation of Wnt pathway signalling can partially restore embryonic development [4].

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.

Physico-chemical Properties

Calculated molecular properties are available for small molecules and natural products (not peptides). Properties were generated using the CDK toolkit. All properties were selected to enable the prediction of the Lipinski Rule-of-Five profile or ‘druglikeness’ for each ligand. For more info on each category see the help pages.

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.

Mechanism Of Action and Pharmacodynamic Effects Click here for help
GSK-3 negatively regulates several aspects of insulin signalling, and upregulated GSK-3 activity may be involved in the development of insulin resistance in type 2 diabetes [5,7] and in neurodegenerative disease [3,6,9]. GSK-3 inhibitors have therefore become the focus of intense drug discovery efforts.
CHIR-99021 is one such investigational inhibitor, which shows >500-fold selectivity for GSK-3 versus its closest homologues cyclin-dependent kinase 1 (CDC2) and mitogen-activated protein kinase 1 (ERK2), as well as other protein kinases [8].
