In this episode of The Alpha Human Podcast, Lawrence delves into drugs that can trigger ferroptosis to kill cancer cells. Ferroptosis is a regulated form of cell death characterized by the accumulation of lipid peroxides and iron-dependent reactive oxygen species, as this can be an Achilles’ heel for cancers that exhibit iron overload.

Although there are currently no approved drugs designed for this purpose, there are a number of existing pharmaceuticals that have demonstrated the ability to incite ferroptosis in cancer cells.

For instance, Lawrence highlights Auranofin, a rheumatoid arthritis drug, and Metformin, a widely prescribed drug for diabetes that has also shown potential for inhibiting cancer invasion and metastasis. Both drugs have demonstrated the ability to induce ferroptotic death in cancer cells.

Additionally, Lawrence discusses the effectiveness of Artesunate, a derivative of artemisinin commonly prescribed as an anti-malarial drug, and Sulfasalazine, primarily used for treating inflammatory bowel diseases like ulcerative colitis, as both have shown the capability to trigger ferroptosis as well.
