Jiang J, Chan A, Ali S, Saha A, Haushalter KJ, Lam WL, Glasheen M, Parker J, Brenner M, Mahon SB, Patel HH, Ambasudhan R, Lipton SA, Pilz RB, Boss GR. Hydrogen Sulfide--Mechanisms of Toxicity and Development of an Antidote. Sci Rep. 2016 Feb 15;6:20831. PMID: 26877209; PMCID: PMC4753484.

From the abstract: "Hydrogen sulfide is a highly toxic gas-second only to carbon monoxide as a cause of inhalational deaths. Its mechanism of toxicity is only partially known, and no specific therapy exists for sulfide poisoning. ... The vitamin B12 analog cobinamide reversed the cellular toxicity of sulfide, and rescued Drosophila melanogaster and mice from lethal exposures of hydrogen sulfide gas. ... We conclude that sulfide produces a high degree of oxidative stress in cells and tissues, and that cobinamide has promise as a first specific treatment for sulfide poisoning."
