| Hazard Information | Back Directory | [Uses]
Tubastatin A is a potent and selective HDAC6 inhibitor with an IC50 of 15 nM in a cell-free assay, and is selective (1000-fold more) against all other isozymes except HDAC8 (57-fold more). Tubastatin A also inhibits HDAC10 and metallo-β-lactamase domain-containing protein 2 (MBLAC2). | [Definition]
ChEBI: A pyridoindole that is 1,2,3,4-tetrahydro-5H-pyrido[4,3-b]indole which is substituted on the tetrahydropyridine nitrogen by a methyl group and on the indole nitrogen by a p-[N-(hydroxy)aminoca
bonyl]benzyl group. It is a histone deacetylase 6 (HDAC6) inhibitor that is selective against all the other isozymes (1000-fold) except HDAC8 (57-fold). | [in vivo]
Daily treatment of Tubastatin A at 0.5 mg/kg inhibits HDAC6 to promote Tregs suppressive activity in mouse models of inflammation and autoimmunity, including multiple forms of experimental colitis and fully major histocompatibility complex (MHC)-incompatible cardiac allograft rejection[2]. | [target]
