Biological Activity

Potent and selective CDK inhibitor (Ki values are 1, 2, 3, 46, 171 and 260 nM for CDK4/cyclin D1, CDK1/cyclin B, CDK2/cyclin E, GSK3α, CDK7/cyclin H and GSK3β). Exhibits no effect against a panel of >120 other kinases (Ki > 5,000 nM). Inhibits the proliferation of tumor cell lines independent of multidrug resistant status, or p53 status. Suppresses retinoblastoma protein in tumor cells and xenografts. Also inhibits tumor growth in the HCT116 human colorectal tumor xenograft model in nude mice. Orally bioavailable.

Cell Cycle & DNA Damage Repair

Cell Cycle & DNA Damage Repair Poster

In normal cells, each stage of the cell cycle is tightly regulated, however in cancer cells many genes and proteins that are involved in the regulation of the cell cycle are mutated or over expressed. Adapted from the 2015 Cancer Product Guide, Edition 3, this poster summarizes the stages of the cell cycle and DNA repair. It also highlights strategies for enhancing replicative stress in cancer cells to force mitotic catastrophe and cell death.
