Cyanide Beyond Toxicity: A Systematic Review of Its Effects on Vascular Function. [PDF]
Basic Clin Pharmacol ToxicolABSTRACT Cyanide is widely recognized for its potent toxicity, yet evidence shows that concentrations below 1 μM may enhance cytochrome c oxidase activity and have a regulatory function. Recent findings also demonstrate that mammalian cells, including endothelial cells, produce cyanide endogenously, where it can modulate mitochondrial bioenergetics ...
