Common Namen-hydroxy(2e,4e,6r)-7-[4-(dimethylamino)phenyl]-4,6-dimethyl-7-oxohepta-2,4-dienimidic acid
DescriptionTrichostatin A, also known as TSA, belongs to the class of organic compounds known as alkyl-phenylketones. These are aromatic compounds containing a ketone substituted by one alkyl group, and a phenyl group. Thus, trichostatin a is considered to be a linear polyketide lipid molecule. TSA can be used to alter gene expression by interfering with the removal of acetyl groups from histones (histone deacetylases, HDAC) and therefore altering the ability of DNA transcription factors to access the DNA molecules inside chromatin. Trichostatin A is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Trichostatin A (TSA) is an organic compound that serves as an antifungal antibiotic and selectively inhibits the class I and II mammalian histone deacetylase (HDAC) families of enzymes, but not class III HDACs (i.E., Sirtuins). TSA has not been tested in clinical trials as of May 27, 2013. Other mechanisms may include the activity of HDIs to induce cell differentiation, thus acting to "mature" some of the de-differentiated cells found in tumors. TSA inhibits the eukaryotic cell cycle during the beginning of the growth stage. HDIs have multiple effects on non-histone effector molecules, so the anti-cancer mechanisms are truly not understood at this time. One suggested mechanism is that TSA promotes the expression of apoptosis-related genes, leading to cancerous cells surviving at lower rates, thus slowing the progression of cancer. n-hydroxy(2e,4e,6r)-7-[4-(dimethylamino)phenyl]-4,6-dimethyl-7-oxohepta-2,4-dienimidic acid is found in Streptomyces sioyaensis. Thus, TSA has some potential as an anti-cancer drug.
