Common NameInuchinenolide B
DescriptionInuchinenolide B belongs to the class of organic compounds known as gamma butyrolactones. Gamma butyrolactones are compounds containing a gamma butyrolactone moiety, which consists of an aliphatic five-member ring with four carbon atoms, one oxygen atom, and bears a ketone group on the carbon adjacent to the oxygen atom. Inuchinenolide B is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Inuchinenolide B is found in Inula hupehensis, Inula japonica and Inula britannica . Inuchinenolide B was first documented in 2015 (PMID: 25993354). Based on a literature review a small amount of articles have been published on inuchinenolide B.
