Trichostatin A: A Potent Inhibitor of Histone Deacetylases (HDACs) with Potent Antitumor Activity

Trichostatin A(R-enantiomer) was originally developed as an antifungal antibiotic agent isolated from the metabolites of strains of Streptomyces hygroscopicus in 1976.1) From the 1980s onwards, it has been reported that trichostatin A is a potent inhibitor of histone deacetylases (HDACs) with potent antitumor activity.2-7) Trichostatin A causes the induction of cell differentiation and specific inhibition of the cell cycle in the G1 and G2 phases at the very low concentrations.For your reference, trichostatin A (R-enantiomer) is the more active enantiomer (eutomer) of (-)-trichostatin A (S-enantiomer) [T3633] (The product is for research purpose only.)
