| INDIRUBIN-3'-MONOXIME Usage And Synthesis |
| Description | Indirubin-3’-oxime is a potent inhibitor of glycogen synthase kinase 3β (GSK3β; IC50 = 22 nM). As GSK3β phosphorylates tau protein, indirubin-3’-oxime prevents tau phosphorylation both in vitro and in vivo at Alzheimer’s disease-relevant sites. It also inhibits cyclin-dependent kinases (CDKs) at higher concentrations, including Cdk1/cyclin B (IC50 = 180 nM), Cdk2/cyclin A (IC50 ~500 nM), Cdk2/cyclin E (IC50 = 250nM), Cdk4/cyclin D1 (IC50 = 3.3 μM) and Cdk5/p35 (IC50 = 100 nM). Indirubin-3’-oxime reversibly inhibits the proliferation of many cells types, arresting cycling in the G2/M phase. | | Chemical Properties | Dark Red Solid | | Uses | A potent inhibitor of GSK-3? (IC50=22nM). Also inhibits CDK1 (IC50=180nM) and CDK (IC50=100nM). It reversibly arrests asynchronous HBL-100 cells at G2. It induces apoptosis in the mammary carcinoma cell line MCF-7 (10üM). | | Uses | Indirubin-3′-oxime has been used in the inhibition of glycogen synthase kinase 3 in human monocytic cell line, THP-1. | | Biological Activity | Protein kinase inhibitor: inhibits cyclin-dependent kinases (IC 50 = 0.18-3.33 μ M) and GSK-3 β (IC 50 = 0.19 μ M). Inhibits CDK5- and GSK-3 β -mediated tau phosphorylation, a process over-active in Alzheimer disease states. Also inhibits AMPK, LCK and SGK. Induces cell cycle arrest and inhibits cell proliferation. | | Biochem/physiol Actions | Indirubin-3′-oxime is a cyclin-dependent kinase inhibitor which functions by competing with ATP for binding to the catalytic subunit; exhibits antiproliferative activity leading to G2/M arrest in many cell lines and G1/S arrest in Jurkat cells. | | References | 1) Leclerc?et al.
