Biological Activity for YKL 5-124

YKL-5-124 is a potent and selective CDK7/Mat1/CycH and cyclin dependent kinase (CDK7) inhibitor (IC50 values = 9.7 nM and 53.5 nM, respectively). YKL-5-124 shows 100-fold selectivity over CDK9 and CDK2. YKL-5-124 induces cell cycle arrest at the G1/S transition, inhibits E2F-driven gene expression and inhibits CDK1 and CDK3 T-loop phosphorylation.

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.
