Overview

Product description

(R)-CR8 (CR8) trihydrochloride, a second-generation analog of Roscovitine, is a potent CDK1/2/5/7/9 inhibitor. (R)-CR8 trihydrochloride inhibits CDK1/cyclin B (IC50=0.09 μM), CDK2/cyclin A (0.072 μM), CDK2/cyclin E (0.041 μM), CDK5/p25 (0.11 μM), CDK7/cyclin H (1.1 μM), CDK9/cyclin T (0.18 μM) and CK1δ/ε (0.4 μM). (R)-CR8 trihydrochloride induces apoptosis and has neuroprotective effect[1][2]. (R)-CR8 trihydrochloride acts as a molecular glue degrader that depletes cyclin K.
