Fenbendazole exerts its primary pharmacological action through selective binding to β-tubulin, the structural subunit of microtubules. This binding inhibits tubulin polymerisation, disrupting the cytoskeletal network and mitotic spindle apparatus. In helminth models, this impairs glucose uptake, energy metabolism, and cell division.

Cell cycle arrest / cell death (parasite or target cell)
Fenbendazole binds with higher selectivity to parasite tubulin than to mammalian tubulin isoforms — making it a valuable tool for species-specific tubulin pharmacology research. At research concentrations it is routinely used as a positive control for microtubule disruption assays.
| Pharmacological Class | Benzimidazole carbamate; β-tubulin polymerisation inhibitor |
| Primary Target | β-tubulin (colchicine-binding site) |
| IC₅₀ (tubulin polymerisation) | ~1–10 µM (cell-line and species dependent) |
| Selectivity | Parasite > mammalian tubulin (structure-dependent) |
| Metabolites of Interest | Fenbendazole sulfoxide (oxfendazole); fenbendazole sulfone |
| Typical Working Conc. | 0.1–50 µM depending on assay system |
| Vehicle Recommendation | Dissolve in DMSO to 10–30 mM stock; dilute in buffer/media (<0.1% DMSO final) |
