Biological Activity for LY 2603618

LY 2603618 is a potent and selective Chk1 inhibitor (IC50 = 7 nM). Inhibits Chk1 autophosphorylation. Induces cell cycle arrest in the G2/M phase and induces the DNA damage response in lung cancer cells. Inhibits growth of NSCLC xenografts in mice when administered in combination with Pemetrexed (Cat.No. 6185).

Cell Cycle & DNA Damage Repair Poster

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. 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.
