Butyrolactone 3 (MB-3)
Catalog No. A24576

Butyrolactone 3 (MB-3) is a specific small-molecule inhibitor of the histone acetyltransferase Gcn5, exhibiting an IC₅₀ of 100 μM and binding affinity comparable to that of its natural substrate, histone H3. It displays weak inhibitory activity against CBP (IC₅₀ = 0.5 mM), indicating high selectivity for Gcn5. By modulating histone acetylation and epigenetic regulation, Butyrolactone 3 serves as a valuable research tool for exploring the roles of Gcn5 in cancer, metabolic disorders, autoimmune diseases, and neurological conditions.
