Tubastatin A TFA 生物活性

描述

Tubastatin A exhibits significant selectivity towards all 11 HDAC isoforms, maintaining over 1000-fold selectivity against all isoforms except HDAC8, for which it demonstrates approximately 57-fold selectivity. In assays assessing homocysteic acid (HCA)-induced neurodegeneration, Tubastatin A demonstrates dose-dependent protection against HCA-induced neuronal cell death, with significant protection observed at 5 μM and near-complete protection at 10 μM^[1]. Treatment of CC12 cells with Tubastatin A results in impaired myotube formation when alpha-tubulin undergoes early hyperacetylation during the myogenic process; however, myotube elongation occurs when alpha-tubulin is hyperacetylated in mature myotubes^[3]. A recent study suggests that treatment with Tubastatin A enhances cell elasticity, as demonstrated by atomic force microscopy (AFM) tests, without causing significant alterations to the actin microfilament or microtubule networks in mouse ovarian cancer cell lines, MOSE-E and MOSE-L^[4].

体内研究

Daily administration of Tubastatin A at a dose of 0.5 mg/kg suppresses HDAC6, thereby enhancing the suppressive function of Tregs in mouse models of inflammation and autoimmunity, including various experimental colitis models and fully major histocompatibility complex (MHC)-incompatible cardiac allograft rejection^[2].
