2-(R)-(1-Ethyl-2-hydroxyethylamino)-6-(4-(2-pyridyl)benzyl)-9-isopropylpurinetrihydrochloride Chemical Properties,Usage,Production

Description

CR8 (294646-77-8) is a second generation analog of roscovitine which inhibits cyclin-dependent kinases with increased potency, Cdk1/cyclin B, Cdk2/cyclin A, Cdk2/cyclin E, Cdk5, p25, and Cdk9/cyclin T, IC50s=0.09, 0.072, 0.041, 0.11 and 0.18 μM respectively.1,2 Acts as a molecular glue degrader that depletes cyclin K.3 CR8 displays neuroprotective effects in various models including traumatic brain injury.4

Uses

CR8, (R)-Isomer is a cell-permeable, ATP-binding pocket-targeting CDK/CK1 dual-specific inhibitor.

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.
