In Vitro | In vitro activity: Tubacin, without directly stabilizing microtubules, induces an increase in α-tubulin acetylation with EC50 of 2.5 μM in A549 cells. Tubacin inhibits HDAC6-mediated α-tubulin deacetylation, and inhibits the migration of both wild-type and HDAC6-overexpressing cells. Tubacin, in combination with paclitaxel, synergistically enhances tubulin acetylation. Tubacin significantly inhibits both drug-sensitive and drug–resistant MM cell growth with IC50 of 5–20 μM, and induces cell apoptosis by activation of caspases. Kinase Assay: Enzyme inhibition assays are performed using the Reaction Biology HDAC Spectrum platform. The HDAC1, 2, 4, 5, 6, 7, 8, 9, 10, and 11 assays used isolated recombinant human protein; HDAC3/NcoR2 complex is used for the HDAC3 assay. Substrate for HDAC1, 2, 3, 6, 10, and 11 assays is a fluorogenic peptide from p53 residues 379-382 (RHKKAc); substrate for HDAC8 is fluorogenic diacyl peptide based on residues 379-382 of p53 (RHKAcKAc). Acetyl-Lys(trifluoroacetyl)-AMC substrate is used for HDAC4, 5, 7, and 9 assays. Compounds are dissolved in DMSO and tested in 10-dose IC50 mode with 3-fold serial dilution starting at 30 μM. Control Compound Trichostatin A (TSA) is tested in a 10-dose IC50 with 3-fold serial dilution starting at 5 μM. IC50 values are extracted by curve-fitting the dose/response slopes. Cell Assay: The inhibitory effect of bortezomib and/or tubacin on MM cell growth is assessed by measuring 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) dye absorbance. Cell lines used: Drug-sensitive (MM.1S, U266, INA-6, and RPMI8226) and drug-resistant (RPMI-LR5 and RPMI-Dox40) MM cell lines |

In Vivo | In chick embryos, inhibition of HDAC6 activity by Tubacin reduces the formation of new blood vessels in matrigel/nylon mesh. In angioreactors implanted in mice, Tubacin also impairs the formation of new blood vessels. |
