Metabolite Identification
Common Name3-Acetyl-2,7-naphthyridine
Description3-Acetyl-2,7-naphthyridine 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 Naphthyridines are compounds containing a naphthyridine moiety, a naphthalene in which a carbon atom has been replaced by a nitrogen in each of the two rings.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. 3-Acetyl-2,7-naphthyridine has been detected, but not quantified in, several different foods, such as herbal tea, fats and oils, green tea, teas (Camellia sinensis), and red tea. This could make 3-acetyl-2,7-naphthyridine a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 3-Acetyl-2,7-naphthyridine.
