Description

Methylene bis(4-cyclohexylisocyanate), also known as dicyclohexylmethane 4,4'-diisocyanate or 4,4'-diisocyanatodicyclohexylmethane, belongs to the class of organic compounds known as isocyanates. These are organic compounds containing the isocyanic acid tautomer, HN=C=O, of cyanic acid, HOC#N or its hydrocarbyl derivatives RN=C=O. Cyanide is mainly metabolized into thiocyanate by either rhodanese or 3-mercaptopyruvate sulfur transferase. Cyanide is an inhibitor of cytochrome c oxidase in the fourth complex of the electron transport chain (found in the membrane of the mitochondria of eukaryotic cells). The binding of cyanide to this cytochrome prevents transport of electrons from cytochrome c oxidase to oxygen. It complexes with the ferric iron atom in this enzyme. Methylene bis(4-cyclohexylisocyanate) is an extremely weak basic (essentially neutral) compound (based on its pKa). Methylene bis(4-cyclohexylisocyanate) is a potentially toxic compound. Cyanide is also known produce some of its toxic effects by binding to catalase, glutathione peroxidase, methemoglobin, hydroxocobalamin, phosphatase, tyrosinase, ascorbic acid oxidase, xanthine oxidase, succinic dehydrogenase, and Cu/Zn superoxide dismutase. Chronic inhalation of cyanide causes breathing difficulties, chest pain, vomiting, blood changes, headaches, and enlargement of the thyroid gland. Cyanide is rapidly alsorbed through oral, inhalation, and dermal routes and distributed throughout the body. Cyanide poisoning is identified by rapid, deep breathing and shortness of breath, general weakness, giddiness, headaches, vertigo, confusion, convulsions/seizures and eventually loss of consciousness. This compound has been identified in human blood as reported by (PMID: 31557052 ). Hydrogenated mdi is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Hydrogenated MDI 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.
