Biological Activity

AZD5438 is a novel, orally bioavailable, cyclin-dependent kinase (CDK) inhibitor demonstrating preclinical pharmacodynamic (PD) effects on CDK substrates and active growth inhibition of human tumour xenografts. In vitro, AZD5438 showed significant antiproliferative activity in human tumor cell lines (IC50 range, 0.2-1.7 μM), causing inhibition of the phosphorylation of cdk substrates pRb, nucleolin, protein phosphatase 1a, and RNA polymerase II COOH-terminal domain and blocking cell cycling at G2-M, S, and G1 phases. AZD5438 blocks cell cycling at G2-M, S and G1 phases; reduces the proportion of actively cycling cells in vivo. The modest PD effect, short plasma t1/2 and close PK-PD relationship suggest that multiple daily dosing or sustained release formulations at higher doses will be necessary for AZD5438 to achieve sustained inhibition of CDK in human cancers.

Protocol
Cell Experiment
Cell lines MCF-7, MDA-MB-231, HCT-116, HT29, LoVo, SW620, Colo-205 cells line
Preparation method Measurement of Cell Proliferation
AZD5438 was tested against solid tumor cell lines as previously described. Briefly, cells were incubated for 48 h with AZD5438 at a range of concentrations. At the end of incubation, the cells were pulsed with 5-bromo-2′-deoxyuridine (BrdUrd) and the amount of DNA synthesis was measured. The IC50 for inhibition of proliferation was specifically determined independently of cell death. Multiple myeloma cell lines were seeded into 96-well plates in RPMI 1640 supplemented with 10% FCS and glutamine and dosed with AZD5438 for 72 h. Cell growth was measured using AlamarBlue (Invitrogen) and GI50 values were calculated with reference to pretreatment control values.

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.
