生物活性

(R)​-​CR8 (CR8), a second-generation analog of Roscovitine, is a potent CDK1/2/5/7/9 inhibitor. (R)​-​CR8 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 induces apoptosis and has neuroprotective effect. (R)-CR8 acts as a molecular glue degrader that depletes cyclin K.

体外研究

(R)-CR8 (CR8) (0.1-100 μM; 48 hours) is a potent inducer of apoptotic cell death with an IC50 of 0.49 μM for SH-SY5Y cell line.
(R)-CR8 (0.25-10 μM) induces a dose-dependent induction of poly-(ADP-ribose)polymerase (PARP) cleavage.
The CDK-bound form of (R)-CR8 has a solvent-exposed pyridyl moiety that induces the formation of a complex between CDK12-cyclin K and the CUL4 adaptor protein DDB1, bypassing the requirement for a substrate receptor and presenting cyclin K for ubiquitination and degradation.
