Biological Activity

AKAP disruptor. Selectively binds PKA-RII subunit with high affinity (Kd = 6.2 nM) and blocks its interaction with AKAP. Cell permeable. Selectively permeable to malaria-infected red blood cells and displays antimalarial activity through a PKA-independent mechanism.

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.
