PROTAC BET Degrader-14

PROTACBET Degrader-14 is a potent PROTAC compound designed to target BET (bromodomain and extraterminal domain) proteins. It effectively degrades all family members of BET, including BRD2, BRD3, and BRD4. The compound demonstrates significant efficacy in degrading BET proteins in the U2OS osteosarcoma cell line (BRD4 DC50 = 130 nM) and the KYSE180 esophageal squamous cell carcinoma cell line (DC50 = 40 nM) . Its mechanism of degradation relies on the ubiquitin-proteasome system. Furthermore, PROTACBET Degrader-14 reduces the expression levels of BET-regulated gene products such as c-Myc, RUNX2, and KRT14, making it a valuable tool for osteosarcoma research.
