Biochem/physiol Actions

CR8 is a potent and selective inhibitor of cyclin dependent kinase (CDK1, 2, 5, 7, and 9). CR8 is a more potent pyridyl analogue of roscovitine (Cat. No. R7772). In comparison to roscovirtine, the compound gains in potency toward CK1, which is involved in amyloid-β formation. The R-CR8 enantiomer is slightly more potent than S. CR8 is around 30 times more potent at cellular assay then roscovitine. Acts as a molecular glue to induce cyclin K degradation.

Traumatic brain injury (TBI) patients in military settings can be exposed to prolonged periods of hypobaria (HB) during aeromedical evacuation. Hypobaric exposure, even with supplemental oxygen to prevent hypoxia, worsens outcome after experimental TBI, in part by increasing neuroinflammation. Cell

Apoptosis of post-mitotic neurons plays a significant role in secondary tissue damage following traumatic spinal cord injury (SCI). Activation of E2F1-dependent transcription promotes expression of pro-apoptotic factors, including CDK1; this signal transduction pathway is believed to represent an important mechanism

Cyclin-dependent Kinases (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.
