Common NameNeocuproine
Descriptionneocuproine, also known as DMPHEN, belongs to the class of organic compounds known as phenanthrolines. These are aromatic polycyclic compounds containing the phenanthroline skeleton, which is a derivative of phenanthrene, and consists of two pyridine rings non-linearly joined by a benzene ring. Relative to 1,10-phenanthroline, neocuproine bears steric bulk flanking the nitrogen donor sites. Neocuproine has also been discovered to have properties that cause fragmentation and disappearance of the melanin in adult zebrafish melanocytes. Neocuproine is a heterocyclic organic compound and chelating agent. neocuproine is a very strong basic compound (based on its pKa). Neocuproine proved to be highly selective for copper(I). Neocuproine can be prepared by sequential Skraup reactions (Doebner-Miller reaction/condensation) of o-nitroaniline (2-Nitroaniline) with crotonaldehyde diacetate. This method gives higher yields but is less economical. This compound has been identified in human blood as reported by (PMID: 31557052 ). Neocuproine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Neocuproine 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.
