VX 680
Biological Activity
High affinity and selective Aurora kinase inhibitor (Ki values are 0.6, 5 and 18 nM for Aurora A, Aurora C and Aurora B, respectively). Also exhibits affinity for FLT-3 and Abl. Exhibits selectivity for Aurora kinase over 190 other protein kinases. Inhibits proliferation and induces apoptosis in a number of cancer cell lines in vitro. Reduces tumor size in leukemia and colon cancer cell xenografts in mice.

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.
