CT-4 New

Product Description

CT-4 is a potent and selective histone deacetylase 8 (HDAC8) Degrader (PROTAC^®) (DC₅₀ = 1.8 nM after 24 h, D_max 97%). Comprises a HDAC8-binding moiety joined by a linker to pomalidomide as the ligand for cereblon (CRBN) protein. Displays 20-fold selectivity over HDAC6 (DC₅₀ = 38 nM after 24 h, D_max 69%) and it does not degrade other HDACs. Displays significant effect on metastasis of MDA-MB-231 cells, and induces degradation and cell death in T-cell leukemia Jurkat cells. Outperformed HDAC8 inhibitors in oncology models. HDAC8 mediates signalling via scaffolding functions in HDAC8/p53/fusion protein complexes, also interacts with STAT3, cAMP and DEC1 via scaffolding functions.
