BH3I-1（Cat No.:I003045） is an antagonist of the Bcl-2 family of proteins, known for its ability to inhibit the binding of the Bak BH3 peptide to Bcl-xL. It exhibits a Ki value of 2.4±0.2 μM for this interaction. Additionally, BH3I-1 has a dissociation constant (Kd) of 5.3 μM for the interaction between p53 and murine double minute 2 (mDM2), an important interaction involved in regulating the activity of the tumor suppressor protein p53. BH3I-1’s ability to disrupt these protein-protein interactions makes it a valuable tool for studying and potentially modulating apoptotic pathways and p53-mediated responses.
