When applied to human non-small cell lung cancer (NSCLC) tumor cell lines (H460 and A549) that have wild-type p53, fenbendazole (1 uM; 24 hours) dramatically slows cell growth [1]. Perfect p53 protein levels are raised and cell engraftment is induced by fenbendazole (1 uM; 24 hours) [1]. Human NSCLC cells undergo the mitotic phase of the cell life cycle when exposed to 1 uM of fenbendazole for 24 hours [1]. Azole (1 uM; 24 hours) can partially alter the A549 cells' microtubule network [1].

For 12 days, fenbendazole (1 mg; oral; once daily) can dramatically reduce the weight and size of tumors [1].

| Cell Assay |
Cell cycle analysis [1]
Cell Types: A549 cells Tested Concentrations: 1 uM Incubation Duration: For 24 h Experimental Results: Caused an early increase in cyclin B1/CDK1 levels (8 hrs (hours) compared to 16 hrs (hours) for control untreated cells). p-Histone H3 (Ser10) was found to be upregulated at 12 and 24 hrs (hours). Apoptosis analysis [1] Cell Types: A549 Cell Tested Concentrations: 1 uM Incubation Duration: 8, 16, 24, 32, 40, 48 hrs (hours) Experimental Results: The number of apoptotic cells increased in a time-dependent manner, along with cyclin B1 levels diminished, and approximately 30% of the cells underwent apoptosis after 32 hrs (hours). Western Blot Analysis[1] Cell Types: H460 Cell Tested Concentrations: 1 uM Incubation Duration: 24 hrs (hours) Experimental Results: Resulted in increased p53 protein levels in mitochondrial fractions. |
| Animal Protocol |
Animal/Disease Models: Female athymic nu/nu (nude) mice xenografted with A549 cells[1]: 1 mg/mouse
Route of Administration: Oral; every other day for 12 days Experimental Results: Result in significant reduction in tumor size and weight . The resulting decrease in hemoglobin content in the tumor means a decrease in the tumor's vascular supply. |

| Additional Infomation |
Fenbendazole belongs to the benzimidazole class of compounds, with the structure 1H-benzimidazole, substituted at positions 2 and 5 by (methoxycarbonyl)amino and phenylthioyl groups, respectively. It is a broad-spectrum anthelmintic, particularly used in veterinary medicine to treat nematode infections. Fenbendazole is an anti-nematode drug belonging to the benzimidazole, carbamate, and aryl thioether classes of compounds. It is a benzimidazole compound with broad-spectrum anthelmintic activity and can be used to treat various gastrointestinal parasitic infections, including Giardia lamblia, Ascaris lumbricoides, hookworms, whipworms, tapeworms, pinworms, Strongyloides pulmonale, paragonimiasis, and Strongyloides stercoralis. Fenbendazole is approved for use under veterinary guidance in sheep, cattle, horses, fish, dogs, cats, rabbits, and seals.
Anti-nematode benzimidazole drugs used in veterinary medicine. See also: Bacitracin methylene disalicylate; Fenbendazole (component); Fenbendazole; Ivermectin; Praziquantel (component). Indications For the treatment and control of gastrointestinal nematode infections in pigs, including: Ascaris suis (adult, intestinal, and migrating larval stages); Nematodes spp. (adult stage); Trichodeda spp. (adult stage). For the treatment of gastrointestinal nematode infections in chickens, including: Ascaris suis (L5 stage and adult stage); Heterakis gallinarum (L5 stage and adult stage); Capillaria spp. (L5 stage and adult stage). |

| Solubility (In Vitro) |
DMSO : ~10 mg/mL (~33.41 mM)

|---|---|
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 1 mg/mL (3.34 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 10.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. Solubility in Formulation 2: ≥ 1 mg/mL (3.34 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 10.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly. (Please use freshly prepared in vivo formulations for optimal results.) |
