I-BET567(Cat No.:I045210)is a potent, selective inhibitor of bromodomain and extra-terminal (BET) family proteins, including BRD2, BRD3, and BRD4, which regulate gene transcription by recognizing acetylated lysine residues on histones. By blocking BET–chromatin interactions, I-BET567 suppresses expression of oncogenes such as MYC, leading to reduced tumor cell proliferation and survival. It has demonstrated strong activity in preclinical models of hematologic malignancies and solid tumors. I-BET567 is a valuable research tool for studying epigenetic regulation, transcriptional control, and cancer biology, with therapeutic potential in oncology and inflammation-driven diseases.
