Fenbendazole is an orally active benzimidazole anthelmintic agent, with a broad antiparasitic range. Fenbendazole is a microtubule destabilizing agent and acts on helminthes primarily by binding to tubulin and disrupting the tubulin microtubule equilibrium. Fenbendazole stabilizes the transcriptional activator HIF-1α. Fenbendazole possesses an efficient anti-proliferative activity and induces apoptosis. Fenbendazole causes cell-cycle arrest and mitotic cell death, and has antitumor activity in mice xenografted with wild-type p53.

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
