Parbendazole is a potent inhibitor of microtubule assembly, destabilizes tubulin, with an EC50 of 8.79 nM, and exhibits a broad-spectrum anthelmintic activity.
Parbendazole is a tubulin destabilizer, with an EC50 of 8.79 nM, and can induce DNA damage[1]. Parbendazole (2-10 μM) inhibits the assembly of microtubules dose-dependently, with an IC50 of 3 μM. Parbendazole (2-20 μM)-treated cells show an complete absence of microtubules in Vero cells[2]. Parbendazole (up to 10 μM) inhibits the growth of CLd-AXE myxamoebae. Parbendazole (2-5 μM) potently inhibits tubulin purified from the wild-type myxamoebae[3].

Kinase experiment: | Pure tubulin is obtained from sheep brain by 2 cycles of assembly and disassembly in vitro. Immediately prior to use the protein is centrifuged at 130000 g for 30 min to remove any aggregates. It is used at a protein concentration of 0-2 mg/mL in 0.025 M Pipes buffer, 0-5 mM EGTA, 0-25 mM Mg2SOsup>4, 0.1 mM GTP. Drug binding is determined by equilibrium dialysis using concentrations of parbendazole between 0.1 μM and 4 μM, and 2% (v/v) DMF (dimethyl formamide) as a carrier. Equilibrium is achieved by constant stirring for 2 h at 26°C, bovine serum albumin being used as a standard. 200 μL aliquots are counted in PCS in a 25-200B liquid scintillation counter[2]. |
Cell experiment: | Vero cells, an established cell line derived from monkey kidney are seeded in DMEM supplemented with 10% (v/v) foetal calf serum onto glass coverslips in multiwell dishes. They are allowed to settle, and spread for 2-5 h in a humid atmosphere at 37°C. After this time the medium is changed to DMEM containing 2, 10 or 20 μM parbendazole and 1% (v/v) DMSO controls contained 1 % (v/v) DMSO or had no additions[2]. |

General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |
