What is SB216763?

Description

SB-216763 (280744-09-4) is a potent and selective inhibitor of glycogen synthase kinase-1 (GSK-3) IC50=34.3 nM.1 Acts at the ATP-binding domain. Displays protective effects in lung fibrosis mouse model.2 Displays neuroprotective effects on cultured neurons.3 SB-216763 maintains mouse embryonic stem cells in a pluripotent state.4?Cell permeable.

The Uses of SB216763

SB 216763 is a potent and selective cell permeale ATP-competitive inhibitor of GSK3a. It stimulates glycogen synthesis in Chang human liver cells.

The Uses of SB216763

SB-216763 was used to inhibit GSK-3β in human brain microvascular endothelial cell line and colorectal cancer cells.

What are the applications of Application

SB-216763 is a potent, selective and ATP-competitive inhibitor of GSK-3α and GSK-3β

Definition

ChEBI: 3-(2,4-dichlorophenyl)-4-(1-methyl-3-indolyl)pyrrole-2,5-dione is a member of indoles and a member of maleimides.

Biological Activity

Potent and selective glycogen synthase kinase-3 (GSK-3) inhibitor (K i = 9 nM for GSK-3 α ); competes with ATP. Has minimal activity against 24 other protein kinases (IC 50 > 10 μ M). Stimulates glycogen synthesis, gene transcription and is neuroprotective.

Biochem/physiol Actions

SB-216763 is a small molecule that competes with ATP and potently inhibits the activity α and β isozymes of GSK-3. It acts as neuroprotectant and prevents neuronal cell death induced by PI3-kinase pathway. It also delays preconditioning, reduces infarct size and prevents cardiac ischemia.

Storage

Room temperature
