Trichostatin A (TSA) is a fungal antimycotic from the bacterium Streptomyces platensis and selectively blocks class I and class II histone deacetylases (HDAC) in mammals; but not HDAC Class III / Sirtuins .

TSA also blocks the eukaryotic cell cycle during the onset of cell division .

TSA can be used to alter gene expression by inhibiting the removal of acetyl groups on histones ( histone deacetylases , HDAC). This improves the ability of the transcription factors to dock onto DNA promoter areas .

Since histone deacetylases, which inhibit the expression of tumor-suppressing genes, are often active in cancer cells , trichostatin A has potential as a cancer drug. One theory about the mechanism of action of TSA states that the antibiotic upregulates the expression of apoptosis genes, thus reducing the likelihood of cancer cells surviving. Other theories see TSA as an inducer of cell differentiation , which causes the growth of otherwise dedifferentiated and thus divisible cancer cells to stop.

Trichostatin A has hardly been used in clinical studies to date.
