RO-3306 may act to inhibit CDK1/cyclin B1 and CDK1/cyclin A. It also inhibits CDK2 (Ki = 340 nM), PKCδ (Ki = 318 nM), and serum- and glucocorticoid-induce kinase (Ki = 497 nM) but not CDK4.1. It reversibly arrests human cells at the G2/M border of the cell cycle and allows for effective cell synchronization without the use of microtubule poisons in early mitosis. Prolonged treatment of cells with RO-3306 induces apoptosis and this can be augmented in acute myeloid leukemia cells by stimulating p53 activity with nutlin-3.3. In other words, RO-3306 actively enhances downstream p53 signaling to promote apoptosis.
