LL-K8-22
Based on 1 Customer Validation
LL-K8-22 is a potent, selective and durable PROTAC CDK8-cyclin C dual degrader, with DC50 values of 2.52 and 2.64 μM, respectively. LL-K8-22 also suppresses STAT1 Ser 727 phosphorylation. LL-K8-22 inhibits E2F- and MYC-driven carcinogenic transcriptional programs. LL-K8-22 can be used for triplenegative breast cancer (TNBC) research.
(Pink: CDK8 ligand (HY-168683); Blue: hyt ligand (HY-N2427); Black: linker).

Incubation Time:24 h
-
Result:Induced selective and synchronous degradation of CDK8 and cyclin C protein expression in a dose-dependent manner with DC50 of 2.52 and 2.64 μM, respectively. Significantly degraded CDK8 without reducing CDK19 (a highly homologous protein of CDK8) and did not degrade other cyclin proteins except cyclin C.
