General description

Trichostatin A (TSA) is a potent and specific inhibitor of histone deacetylase (HDAC) activity. It is an antifungal antibiotic with cytostatic and differentiating properties in mammalian cell culture.

Application

Trichostatin A (TSA) has been used during the production of cloned mouse embryos. TSA has also been used as a histone deacetylase (HDAC) inhibitor in LNCaP human prostate cancer cells, as well as in MON and HeLa cells.

Biochem/physiol Actions

Trichostatin A (TSA) inhibits histone deacetylase at nanomolar concentrations; resultant histone hyperacetylation leads to chromatin relaxation and modulation of gene expression. May be involved in cell cycle progression of several cell types, inducing cell growth arrest at both G and G/M phases; may induce apoptosis. Enhances the efficacy of anticancer agents that target DNA. Trichostatin A serves as an epigenetic modifier.

Features and Benefits

Preparation Note

Trichostatin A is soluble in methanol at 1.90 - 2.10 mg/ml and yields a clear, colorless to faint yellow/tan solution. It is also soluble in DMSO, DMF, acetonitrile, ethanol and lower alcohols. Trichostatin A is sparingly soluble in chloroform, ethyl acetate, acetone, and benzene. However, it is insoluble in water.
