HDAC inhibitors
Histone deacetylase (HDAC) inhibitors are compounds that interfere with the activity of histone deacetylase enzymes, which play a crucial role in regulating gene expression through modification of histone proteins. HDACs remove acetyl groups from lysine residues on histone tails, leading to chromatin condensation and transcriptional repression. By inhibiting HDAC activity, HDAC inhibitors increase histone acetylation levels, which can alter chromatin structure and promote a more open configuration that allows for increased gene transcription. This mechanism has implications in various cellular processes, including cell cycle regulation, apoptosis, and differentiation.
