Introduction Lysine-specific demethylase 1 (LSD1) and histone deacetylase 6 (HDAC6) are key epigenetic regulators involved in histone demethylation and deacetylation, processes that impact chromatin structure and gene expression. JBI-802 marks a major advancement as the first novel, orally available LSD1/HDAC6 dual inhibitor currently in clinical trials.
