Fenbendazole
A dog dewormer that kills cancer cells through microtubule disruption, p53 and several other pathways, made famous by a rancher's stage 4 lung cancer story.
Real mechanism list in cells and mice, cataloged in a 2024 review.
Poor human bioavailability. Famous case was also on trial immunotherapy so cannot be credited to fenbendazole.
