Biological Activity

AT7519 hydrochloride is a multi-CDK inhibitor for CDK1, 2, 4, 6 and 9 with IC50 of 10-210 nM. AT7519 displays potent cytotoxicity and apoptosis; associated with in vivo tumor growth inhibition and prolonged survival. At the molecular level, AT7519 inhibited RNA polymerase II (RNA pol II) phosphorylation, a CDK9, 7 substrate, associated with decreased RNA synthesis confirmed by [(3)H] Uridine incorporation. In addition, AT7519 inhibited glycogen synthase kinase 3beta (GSK-3beta) phosphorylation.

Cell Experiment
Cell lines MM.1S, MM.1R, RPMI8226, U266, RPMI8266, RPMI-Dox40, OPM1 cells, primary MM cells and PBMNCs
Preparation method Incubating cells with different concentrations of AT7519 for 24 or 48 hours at 37°C. Assaying cell viability by measuring 3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyl tetrasodium bromide (MTT) dye absorbance. Measuring DNA synthesis by tritiated thymidine uptake (3H-TdR).Assessing Apoptosis by using Annexin V/PI staining. Defining the percentage of cells undergoing apoptosis as the sum of early apoptosis (Annexin V-positive cells) and late apoptosis (Annexin V-positive and PI-positive cells
Concentrations Dissolved in DMSO at a concentration of 10 mM, final concentrations 0.25-4 μM
Incubation time 24 or 48 hoursMale SCID mice inoculated subcutaneously with MM.1S cells

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
