Trichostatin A (TSA, CAS 58880-19-6) is a histone deacetylase (HDAC) inhibitor and antifungal antibiotic isolated from microbial sources. TSA acts by reversibly inhibiting HDAC enzymes in a noncompetitive manner, leading to increased acetylation of histones, particularly histone H4. In mammalian cell cultures, TSA treatment results in G1 and G2 phase arrest, induction of differentiation, and reversion of transformed cellular phenotypes. In human breast cancer cell lines, TSA inhibits proliferation (IC50 = 124.4 ± 120.4 nM) and induces hyperacetylation of histone proteins, highlighting its utility as a tool compound for investigating epigenetic regulation and oncology-related mechanisms.
