Factsheet

Trichostatin A (TSA) is an antibiotic and antifungal isolated from small bacteria, Streptomyces. It is a specific inhibitor of certain classes of enzymes, histone deacetylases (HDAC), having a major role in the preservation and folding of our DNA. The action of trichostatin A on HDAC causes chromatin condensation and represses gene transcription. In cancer cells, inhibition of HDACs by trichostatin A can cause cell death, cell growth arrest or induce cell differentiation. Today, trichostatin is used in research and proves its efficacy in vitro and in vivo, but it is not yet used in therapy in humans.

Many anti-aging applications

Trichostatin A as a promising anti-tumor agent

HDAC inhibitors are new and highly studied anti-tumor agents. They influence cancer cells by promoting cell death, apoptosis, cell cycle arrest and autophagy, primarily by restoring transcription of tumor suppressor genes or activating important cell regulatory pathways. This molecule has demonstrated its efficacy in several studies conducted on different types of cancer (glioblastoma, breast cancer, pancreatic cancer, chronic lymphoid leukemia, etc.) for which trichostatin A promoted apoptosis of tumor cells[1, 2, 3, 4]. Its use, coupled with other therapeutic approaches in cancerology, could improve the prognosis of cancer patients.

Beneficial effects on kidney diseases

Trichostatin A has been the subject of numerous publications in which its strong therapeutic potential against several renal diseases is exposed. Treatment with trichostatin A decreases renal fibrosis progression in mice and reduces cyst formation in polycystic renal disease[5]. It also stimulates autophagy in some experimental models of acute renal failure[6]. Finally, it would have beneficial effects on diabetic nephropathies or those associated with HIV.

Neuroprotection

Trichostatin A mediated hyperacetylation is neuroprotective. This molecule could eliminate beta-amyloid proteins from the brain, among others, and can therefore be considered as a potential therapeutic agent in Alzheimer’s disease[7].

A molecule that works for longevity

By preventing histone deacetylation, trichostatin A promotes and increases the expression of HSP (Heat Shock Protein) genes that protect cells from various stresses. Trichostatin A has been shown to prolong the life of different Drosophila lines by this mechanism[8]. Another study published in Aging Cell in 2016[9] showed that trichostatin A increased the lifetime of C. elegans by a mechanism mimicking caloric restriction. Trichostatin A therefore has a positive effect on longevity, making it a potential drug candidate for the development of compounds that promote longer healthy life.

  • Number of publications: over 4000
  • Availability: not available over the counter, only for scientific research
  • Route: injection
  • Dosage: not tested in humans, 0.5 to 10 mg/kg in mice, 50 to 2000 nM in cell cultures

Today, Trichostatin A is a molecule recognized as being active on cellular and animal models against several age-related diseases, but it has never yet been administered to humans. The relevant studies are in the pre-clinical phase, in vitro and in vivo.

There are no data on toxicology and therapeutic doses in humans.
