Tubastatin A is a potent and selective HDAC6 inhibitor with IC50 of 15 nM in a cell-free assay. Tubastatin A is a very selective HDAC6 inhibitor with 100 to over 1000-fold selectivity for HDAC6 over other HDAC classes. 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 the mouse model of Charcot-Marie-Tooth disease. Tubastatin A inhibits the deacetylation of α-tubulin in murine myoblasts.

rTg4510 mice were used for activity evaluation. Tubastatin A was administered using daily intraperitoneal injections into rTg4510 mice and nontransgenic littermates from 5 to 7 months of age. Each group consisted of six animals per genotype. Mice were weighed, and injected with tubastatin (25 mg/kg) or 0.9% normal saline solution (vehicle).
Route of Administration: Intraperitoneal
TUB (Tubastatin A) enhanced TMZ (Temozolomide)-induced cytotoxicity in different TMZ-resistant cell lines (A172, U118, U251, U87). Cells were pre-incubated with TUB (1-32 mkM) for 12 h and then co-treated with 34mkM of TMZ for 24 h. Cell viability rates were determined by a CCK-8 assay.
