Looks like it. The hypothesis is not completely far out, the benzimidazoles interfere with microtubule assembly, and some chemotherapeutic agents in clinical practice (taxol, the vinca alcaloids) do the same.

The strange thing is that the affinity of benzimidazole anthelmintics to mammalian tubulin is much lower than to roundworm tubulins, but as we say, more research is needed.
