Common NamePhosphocysteamine
Descriptioncysteamine S-phosphate, also known as phosphocysteamine, belongs to the class of organic compounds known as organothiophosphorus compounds. These are organic derivatives of thiophosphonic acid, thiophosphoric acid, dithiophosphoric acid, or phosphorotrithioic acid, or derivatives thereof. Thiophosphonic acid, dithiophosphoric acid, thiophosphoric acid, and phosphorotrithioic acid are thiophosphorus compounds with the formula OP(O)(=S), OP(S)(=S)O, OP(O)(=S)O, and OP(=S)(S)S, respectively. Based on a literature review a significant number of articles have been published on cysteamine S-phosphate. This compound has been identified in human blood as reported by (PMID: 31557052 ). Phosphocysteamine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Phosphocysteamine is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
