Description

Parbendazole is an inhibitor of microtubule assembly (EC50 = 3 ?M).1 It reduces viability of HeLa cells (EC50 = 0.53 ?M) and induces genotoxic stress in a reporter assay using HEK293 cells.2 Parbendazole reduces, but does not eradicate, worm burden in goats with naturally acquired or experimental nematode infections when administered at a dose of 15 mg/kg.3 It is teratogenic to lamb embryos when administered to pregnant ewes at a dose of 60 mg/kg during the third week of pregnancy.

实验参考方法

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].
