Purity >99%. Fusarenon X is a type B trichothecene mycotoxin typically derived from Fusarium species. It is primarily found in contaminated cereals. Fusarenon X inhibits protein synthesis, which leads to disruption of DNA synthesis. As this occurs in actively proliferating cells, fusarenon X causes immunosuppression, intestinal malabsorption, developmental toxicity, and genotoxicity. Fusarenon X can be metabolized to fusarenon X-glucoside by infected plants.
