PD 0332991 isethionate
Biological Activity
Potent Cdk4/6 inhibitor (IC50 values are 11 and 15 nM for Cdk4 and Cdk6 respectively). Selective for Cdk4/6 over a panel of 34 additional protein kinases (IC50 values are > 10 μM). Induces G1 cell cycle arrest and senescence in retinoblastoma protein (Rb)-proficient cell lines; blocks growth of intracranial glioblastoma multiforme xenografts in mice. Brain penetrant.

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.
