Casein Kinase inhibitor A51 is a potent and orally active casein kinase 1α (CK1α) inhibitor. Casein Kinase inhibitor A51 induces leukemia cell apoptosis , and has potent anti-leukemic activities In Vitro Similar to CKIα depletion, Casein Kinase inhibitor A51 (0.05-3.2 μM; 18 hours) treatment of RKO cells abolished most of the Ser45 phosphorylation signal and the consecutive GSK3 phosphorylation cascade resulting in stabilization of β-catenin. Casein Kinase inhibitor A51 is highly effective in inducing leukemia cell apoptosis at 160 nM or lower, mostly in correlation to their capacity to stabilize p53. Casein Kinase inhibitor A51 (0.08-2 μM; 6.5 hours) abolishes the expression of MYC, MDM2, and the anti-apoptotic oncogene MCL1. Casein Kinase inhibitor A51 induces a marked reduction in mRNA expression of MYC and MDM2, yet upregulates the expression of the Wnt targets AXIN2 and CCND1 (Cyclin D1). MCE has not independently confirmed the accuracy of these methods. They are for reference only. Cell Viability AssayCell Line: MV4-11 cells Concentration: 0.08 μM, 0.6 μM, 2 μM Incubation Time: 6.5 hours Result: Abolishes the expression of MYC, MDM2, and the anti-apoptotic oncogene MCL1. In Vivo Oral treatment is initiated at 8 days (Casein Kinase inhibitor A51; 5 mg/kg/day) after leukemia cell inoculation, at which the percentage of leukemia cells in the BM is more than 1.5% of all cells. all A51-treated mice have normal organ morphology and histology and normal blood counts . Pharmacokinetic studies of the inhibitor Casein Kinase inhibitor A51 at 20 mg/kg reveal rapid oral absorption with a T max of 0.5-2 hr, C max of 1060 ng/mL, T 1/2 of 2.5 hr, and area under the curve (AUC) values of 3680 (ng*hr/mL) . MCE has not independently confirmed the accuracy of these methods. They are for reference only. Form:Solid IC50& Target:CKIα CDK7 1.3 nM (Kd) CDK9 4 nM (Kd)
