Description
Tubastatin A (1310693-92-5) is a potent and highly selective inhibitor of HDAC6 (IC50?= 15 nM, >1000-fold selectivity against other HDAC isoforms, approx. 60-fold versus HDAC8).1?It displayed anti-inflammatory and anti-rheumatic effects in Freund’s competitive adjuvant induced animal model of inflammation.2?Tubastatin A inhibited TNF-α (IC50?= 272 nM) and IL-6 (IC50 = 712 nM) in LPS stimulated human THP-1 macrophages.2?Tubastatin A has also been shown to have therapeutic potential for treatment of Alzheimer’s disease via altered amyloid-β load and reduced tau hyperphosphorylation.3-5
Uses
Tubastatin A Hydrochloride is an LSD1 inhibitor, which targets SOX2-expressing cancer cells.
Uses
Tubastatin A Hydrochloride is a neuroprotective HDAC6 inhibitor and is also known to induce hyperacetylation in primary cortical neuron cultures.
Biochem/physiol Actions
Tubastatin A increases the total numbers of mitochondria and restores the number of moving mitochondria in DRG neurons. It reverses the axonal loss in peripheral neurons in mouse model of Charcot-Marie-Tooth disease. Tubastatin A inhibits the deacetylation of α-tubulin in murine myoblasts.
