Features:

Fenbendazole (FBZ) — a benzimidazole anthelmintic used in veterinary medicine. Mechanistically a β-tubulin–binding microtubule destabilizer with secondary metabolic and redox effects reported in preclinical oncology models.

Primary mechanisms (conceptual rank):
1) β-tubulin binding → microtubule depolymerization
2) Mitotic arrest → apoptosis (caspase activation)
3) Glucose uptake / glycolysis interference (reported GLUT inhibition)
4) Redox stress modulation (ROS shifts)
5) p53 pathway interactions (model-dependent)

Bioavailability / PK relevance: Poor aqueous solubility; variable oral absorption; extensively metabolized (e.g., to oxfendazole). Human PK data limited; not approved for human oncology use.

In-vitro vs oral exposure: Many anti-cancer studies use micromolar concentrations; achievable systemic exposure in humans is uncertain and likely lower without optimized formulations.

Clinical evidence status: Preclinical oncology; anecdotal reports only; no controlled oncology RCT evidence.


-Fenbendazole works by binding to tubulin, a protein that is important in cell division, which may theoretically affect rapidly dividing cells like cancer cells. However, this mechanism is not selective for cancer cells and could affect normal cells as well.

-Albendazole and fenbendazole, two approved and commonly used benzimidazole anthelmintics

-Panacure C :1g granules (or 222mg Fenbendazole, for small dogs)

Fenbendazole — Cancer vs Normal Cell Pathway Map

Rank Pathway / Axis Cancer Cells Normal Cells TSF Primary Effect Notes / Interpretation
1 β-Tubulin / Microtubule dynamics ↓ (primary) ↓ (proliferating cells) P/R Mitotic spindle disruption Core mechanism; similar class effect to other benzimidazoles. Selectivity depends on proliferation rate.
2 Mitotic arrest → intrinsic apoptosis ↑ ↑ (high proliferation) R/G Caspase-mediated cell death Follows spindle disruption; cancer cells often more susceptible due to mitotic stress vulnerability.
3 Glucose uptake / Glycolysis (Warburg linkage) ↓ (model-dependent) ↔ R/G Metabolic stress Reported GLUT inhibition and reduced hexokinase activity in some models; secondary mechanism.
4 ROS ↑ (dose-dependent) ↔ / ↑ (high concentration) P/R Oxidative stress amplification Often secondary to metabolic and microtubule stress; may enhance apoptosis.
5 NRF2 axis ↔ / ↓ (context-dependent) ↔ R/G Redox-response modulation Not a primary target; redox shifts may indirectly influence NRF2 signaling.
6 p53 pathway ↑ (model-dependent) ↔ G Tumor suppressor activation Reported stabilization or activation in some cancer lines; dependent on functional p53 status.
7 PI3K/AKT/mTOR ↓ (secondary; model-dependent) ↔ R/G Reduced survival signaling Often downstream of metabolic stress or ROS elevation.
8 HIF-1α ↓ (model-dependent) ↔ G Reduced hypoxia adaptation Linked to metabolic interference; not universally established.
9 Ca²⁺ signaling ↔ (stress-related) ↔ P/R Not a primary axis No consistent evidence of direct Ca²⁺ modulation.
10 Ferroptosis ↔ (investigational) ↔ R/G Not established primary mechanism ROS generation may overlap with lipid peroxidation pathways but not core evidence.
11 Clinical Translation Constraint ↓ (constraint) ↓ (constraint) — PK variability + lack of human oncology data Veterinary drug; limited human PK; no oncology approval; safety at anti-cancer doses unknown.

Type: Protein
GADD153 and CHOP (C/EBP-homologous protein) refer to the same protein. GADD153 stands for "Growth Arrest and DNA Damage-inducible protein 153," while CHOP stands for "C/EBP Homologous Protein."
DDIT3 (DNA Damage Inducible Transcript 3), also known as CHOP (C/EBP Homologous Protein), is a transcription factor that plays a significant role in the cellular response to stress, particularly in the context of the unfolded protein response (UPR) and apoptosis.

CHOP is an important component of the endoplasmic reticulum (ER) stress response. Research has shown that knockdown of CHOP not only enhances tunicamycin-induced autophagy, but also significantly attenuates ER stress-induced apoptosis in human colon cancer cells.
GADD153, also known as CHOP (C/EBP homologous protein), is a transcription factor that plays a significant role in cellular stress responses, particularly in the context of the endoplasmic reticulum (ER) stress response. It is part of the unfolded protein response (UPR), which is activated when there is an accumulation of misfolded proteins in the ER.
