BSJ-4-116 is a highly potent and selective CDK12 degrader (PROTAC) with an IC50 of 6 nM.?It downregulates DDR genes through a premature termination of transcription, primarily through increasing poly(adenylation).

SEL120-34A is an ATP-competitive, selective, orally active CDK8 inhibitor that inhibits kinase activities of CDK8/CycC and CDK19/CycC complexes with IC50 of 4.4 nM and 10.4 nM, respectively.

Trilaciclib hydrochloride is an inhibitor of CDK4/6 (IC50s: 1 nM and 4 nM for CDK4 and CDK6).Incubation with Trilaciclib hydrochloride (G1T28) for 24 hours can induce a strong G1 cell cycle arrest (time=0). Cells have re-entered the cell cycle and demonstrate cell-cycle kinetics similar to untreated control cells By 16 hours after Trilaciclib hydrochloride washout.
