Metabolite Identification

Common Name

Squamolone

Description

Squamolone belongs to the class of organic compounds known as pyrrolidinecarboxamides. These are pyrrolidines in which the pyrrolidine rings is substituted at one or more positions by a carboxamide group. Pyrrolidine is a five-membered saturated aliphatic heterocycle with one nitrogen atom and four carbon atoms. Based on a literature review very few articles have been published on Squamolone.
