(E/Z)-HA155（Cat No.:R028712）is a synthetic compound that acts as a selective inhibitor of histone deacetylases (HDACs), enzymes involved in the regulation of gene expression through the modification of histone proteins. By inhibiting HDACs, (E/Z)-HA155 can influence chromatin structure, leading to changes in gene expression that may be beneficial in the treatment of various diseases, including cancer and neurodegenerative disorders. Its ability to modulate gene transcription makes it a promising candidate for therapeutic interventions aimed at restoring normal cellular function in conditions characterized by gene silencing or aberrant gene regulation.
