Background:

Cdk4/6 inhibitor IV is a cell-permeable triaminopyrimidine inhibitor for Cdk4/cyclin D1 and Cdk6/cyclin D1 [1].


Cyclin-dependent kinase 4 (Cdk4) is an important cell cycle kinase, since its activity is required for initiating the phosphorylation of the retinoblastoma protein (pRb). Hyperphosphorylation of pRb prevents cells from initiating DNA synthesis, releases the sequestered transcription factors, leading to the loss of pRb's growth-inhibitory function, thus allowing cells to enter S phase [1].


In vitro: Cdk4/6 inhibitor IV showed an inhibitory effect on Cdk4/cyclin D1 and Cdk6/cyclin D1with the IC50 values of 1.5 and 5.6 μM, respectively. Cdk4/6 inhibitor IV exihibited potent selectivity for Cdk4/6 over Cdk5/p35, c-met, v-abl, IGF-1R, insulin receptor, Cdk2/cyclin A, Cdk2/cyclin E, Cdk4/cyclin D2, Cdk6/cyclin D2, and Cdk1/cyclin B with the IC50 values ≥ 10-100 μM. In asynchronous cell lines, at 5-10 μM, Cdk4/6 inhibitor IV blocked retinoblastoma protein phosphorylation at Ser780 and Ser795, inducing cell cycle arrest in the G1 phase and apoptosis.


In vivo: In mice xenografted with human HCT116 colon carcinoma, treatment with of Cdk4/6 inhibitor IV (i.p, 30 mg/kg) after 29 days suppressed tumor growth.
