Common Name

7-Methyl-2-(2-furyl)-1,8-naphthyridine-4(1H)-one

Description

7-Methyl-2-(2-furyl)-1,8-naphthyridine-4(1H)-one, also known as HB(T) or T-STate hemoglobin, belongs to the class of organic compounds known as naphthyridines. Naphthyridines are compounds containing a naphthyridine moiety, a naphthalene in which a carbon atom has been replaced by a nitrogen in each of the two rings. The naphthyridine skeleton can also be described as an assembly two fused pyridine rings, which do not share their nitrogen atom. Based on a literature review very few articles have been published on 7-Methyl-2-(2-furyl)-1,8-naphthyridine-4(1H)-one. This compound has been identified in human blood as reported by (PMID: 31557052 ). 7-methyl-2-(2-furyl)-1,8-naphthyridine-4(1h)-one is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 7-Methyl-2-(2-furyl)-1,8-naphthyridine-4(1H)-one 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.

Chemical Taxonomy

Description

Belongs to the class of organic compounds known as naphthyridines. Naphthyridines are compounds containing a naphthyridine moiety, a naphthalene in which a carbon atom has been replaced by a nitrogen in each of the two rings. The naphthyridine skeleton can also be described as an assembly two fused pyridine rings, which do not share their nitrogen atom.
