General description
An acetoxime analog of BIO, GSK-3 Inhibitor IX (Cat. No. 361550) that exhibits greater selectivity for GSK-3α/β (IC50 = 10 nM) over Cdk5/p25, Cdk2/A and Cdk1/B (IC50 = 2.4 µM, 4.3 µM and 63 µM, respectively). Weakly affects the activities of Cdk4/D1 and many other kinases (IC50 ≥ 10 µM). Also acts as an aryl hydrocarbon receptor agonist in both yeast (EC50 ≥ 0.1 µM) and mammalian (EC50 = 0.16 µM) reporter systems.
An acetoxime analog of BIO, GSK-3 Inhibitor IX (Cat. No. 361550) that exhibits greater selectivity for GSK-3α/β (IC50 = 10 nM) over Cdk5/p25, Cdk2/cyclin A, and Cdk1/cyclin B (IC50 = 2.4 µM, 4.3 µM, and 63 µM, respectively). A weak inhibitor of Cdk4/cyclin D1 and many other non-related kinases (IC50 ≥ 10 µM). Yields BIO (Cat. No. 361550) upon hydrolysis.
