Definitions related to dimercaprol:
-
A metal chelating agent that is used as an antidote in arsenic, gold, lead, mercury and other heavy metal poisoning. Metals form ligands in the body with the sulfhydryl groups of the pyruvate-oxidase enzyme system. This leads to an inhibition of the normal functioning of these enzymes that are dependent on free sulfhydryl groups for their activity. Dimercaprol reverses the enzyme inhibition by chelating the metal and regenerates free sulfhydryl groups, thereby preventing and reversing the metals toxic effects.NCI ThesaurusU.S. National Cancer Institute, 2021
-
An anti-gas warfare agent that is effective against Lewisite (dichloro(2-chlorovinyl)arsine) and formerly known as British Anti-Lewisite or BAL. It acts as a chelating agent and is used in the treatment of arsenic, gold, and other heavy metal poisoning.NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021
