I-CBP112 is primarily used in research settings to study its effects on bromodomain-containing proteins, particularly BRD4. It serves as a selective inhibitor, helping scientists explore the role of these proteins in gene regulation and cellular processes. This compound is valuable in understanding diseases like cancer, where BRD4 plays a significant role in tumor growth and progression. Additionally, I-CBP112 is utilized in developing potential therapeutic strategies by targeting epigenetic mechanisms, offering insights into novel treatments for various disorders. Its application extends to investigating inflammation and immune responses, as BRD4 is also implicated in these pathways.
