How to use

In Vitro:

Tubacin preferentially induces α-tubulin hyperacetylation at a concentration of 2.5 µM, and induces α-tubulin acetylation at 5 µM and protects prostate cancer (LNCaP) cells from hydrogen peroxide-induced death at 8 µM via peroxiredoxin acetylation. Tubacin (2.5 and 5 μM) specifically induces acetylation of α-tubulin in MM cells. Tubacin significantly inhibits both drug-sensitive and drug-resistant MM cell growth, with IC50 5-20 μM at 72 h. Tubacin also induces apoptosis by activation of caspases. Moreover, Tubacin inhibits binding of HDAC6 with dynein, and it induces significant accumulation of polyubiquitinated proteins, when combined with bortezomib. Tubacin and bortezomib induce synergistic antitumor activity in MM cell lines, and inhibits paracrine MM Cell Growth. Tubacin (5 μM) synergistically enhances bortezomib-induced cytotoxicity in patient MM cells without cytotoxicity to PBMCs. Tubacin can concentration-dependently inhibits JEV-induced cytopathic effect and apoptosis, as well as reduces virus yield in human cerebellar medulloblastoma cells. The IC50 of virus yield is 0.26 μM for Tubacin. Tubacin also meaningfully blocks the production of intracellular infectious virus particles, with an IC50 of 1.52 μM. Tubacin induces the hyperacetylation of a HDAC6 substrate Hsp90 and reduces the interaction of Hsp90 with JEV NS5 protein.
