Biological Activity for Ro 3306

Ro 3306 is an ATP-competitive cyclin-dependent kinase 1 (cdk1) inhibitor (Ki values range from 35 to 240 nM depending on cdk1 binding partner). Also reported to inhibit other cdks (Ki values are 0.89-1.32, 0.03 and >2 μM for cdk2, cdk3 and cdk4, respectively). Induces G2/M phase cell cycle arrest and apoptosis. Downregulates the expression of antiapoptotic proteins such as Bcl-2 and survivin and enhances downstream p53 signaling in acute myeloid leukemia (AML). RO 3306 also improves homology-directed repair (HDR) -mediated gene editing in hematopoietic stem and progenitor cells.
