3-Phenylbutyric acid is a chemical compound that functions as a histone deacetylase inhibitor, altering the acetylation status of histones and affecting gene expression. It acts by inhibiting the activity of histone deacetylase enzymes, leading to the accumulation of acetylated histones and modulation of gene transcription. 3-Phenylbutyric Acid is involved in the regulation of chromatin structure and gene expression, impacting cellular processes such as differentiation, proliferation, and apoptosis. By modulating histone acetylation, 3-Phenylbutyric acid may influence the epigenetic regulation of gene expression, potentially impacting various cellular pathways and processes. Its mechanism of action involves the modification of chromatin structure and the regulation of gene transcription, contributing to the understanding of epigenetic mechanisms in cellular function.
