Application

RO-3306 has been used:
  • To study the significance of CA4-mediated cytotoxicity in mitotic arrest
  • In cell cycle synchronization to conduct a study on proteomics
  • As a CDK1 inhibitor, to prevent early mitotic entry

Biochem/physiol Actions

CDK1 (cyclin dependent kinase 1) is considered to be the “master switch” in cell division, which maintains the mitotic state of cells.
RO-3306 is a selective ATP-competitive inhibitor of CDK1. It inhibites CDK1 cyclin B1 activity with Ki of 35 nM, nearly 10-fold selectivity relative to CDK2/cyclin E and over 50-fold relative to CDK4/cyclin D. RO-3306 has been used to cause cell cycle arrest at the G2/M boundary.

CDKs

Cyclin dependent kinases (CDKs) are typical serine/threonine kinases that display the 11 subdomains shared by all kinases. The complete sequence of the Homo sapiens genome shows that among the ~30,000 predicted genes, there are 13 CDKs and 25 cyclins. Eleven CDKS and their associated cyclins have been characterized in man.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
