体外研究

(R)-CR8 (CR8) trihydrochloride (0.1-100 μM; 48 hours) is a potent inducer of apoptotic cell death with an IC ₅₀ of 0.49 μM for SH-SY5Y cell line.
(R)-CR8 trihydrochloride (0.25-10 μM) induces a dose-dependent induction of poly-(ADP-ribose)polymerase (PARP) cleavage.
The CDK-bound form of (R)-CR8 trihydrochloride 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
