Trichostatin A

A potent and reversible inhibitor of histone deacetylase. Blocks cell cycle progression at the G1 phase in HeLa cells and induces a 12-fold increase in intracellular levels of gelsolin. Induces reversion of oncogenic ras-tranformed NIH 3T3 cells to a normal morphology. Inhibits IL-2 gene expression (IC₅₀ = 73 nM) in Jurkat cells and shows immunosuppressive activity in a mouse model. IC₅₀ = 6 nM for HDAC1; 38 nM for HDAC4, and 8.6 nM for HDAC6A.

A potent and reversible, cell-permeable inhibitor of histone deacetylase. Blocks cell cycle progression at the G₁ phase in HeLa cells and induces a 12-fold increase in intracellular levels of gelsolin. Induces reversion of oncogenic ras-transformed NIH/3T3 cells to a normal morphology. Inhibits IL-2 gene expression (IC₅₀ = 73 nM) in Jurkat cells and shows immunosuppressive activity in a mouse model. Down-regulates p57^kip2 in Hep 3Bcells. IC₅₀ = 6 nM for HDAC1; 38 nM for HDAC4, and 8.6 nM for HDAC6A. 10 mM (500 µg/165 µl) solution of Trichostatin A, Streptomyces sp. (Cat. No. 647926) in DMSO is also available.
