Biological Activity for Olaparib

Olaparib is a potent PARP2 and PARP1 inhibitor (IC50 values are 1 and 5 nM, respectively). Olaparib abolishes PARP-1 activity at a concentration of 30-100 nM in SW620 cell lysates. BRCA1-deficient cell lines are hypersensitive to PARP inhibition by Olaparib in comparison with BRCA1- and BRCA2-proficient cells. Olaparib potentiates the antitumor activity of the methylating chemotherapeutic agent Temozolomide (Cat. No. 2706) in xenograft mouse model. Olaparib is orally bioavailable in rats.

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.
