Casein Kinase inhibitor A51 是一种有效且具有口服活性的酪蛋白激酶 1α (CK1α) 抑制剂。Casein Kinase inhibitor A51 可诱导白血病细胞凋亡 (apoptosis),并具有有效的抗白血病活性。
生物活性 | Casein Kinase inhibitorA51 is a potent and orally activecasein kinase1α (CK1α)inhibitor.Casein Kinase inhibitorA51 induces leukemia cellapoptosis, and has potent anti-leukemic activities[1]. |
IC50& Target[1] | CKIα | CDK7 1.3 nM (Kd) | CDK9 4 nM (Kd) |
|
体外研究 (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[1]. 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[1]. 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)[1].
Cell Viability Assay[1] Cell 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. |
|
体内研究 (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[1]. Pharmacokinetic studies of the inhibitor Casein Kinase inhibitor A51 at 20 mg/kg reveal rapid oral absorption with a Tmaxof 0.5-2 hr, Cmaxof 1060 ng/mL, T1/2of 2.5 hr, and area under the curve (AUC) values of 3680 (ng*hr/mL)[1].
