Common NameCandelalide A

DescriptionCandelalide A belongs to the class of organic compounds known as naphthopyrans. Naphthopyrans are compounds containing a pyran ring fused to a naphthalene moiety. Furan is a 6 membered-ring non-aromatic ring with five carbon and one oxygen atoms. Naphthalene is a polycyclic aromatic hydrocarbon made up of two fused benzene rings. Candelalide A 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. Candelalide A is found in Clonostachys candelabrum and Sesquicillium. Candelalide A was first documented in 2005 (PMID: 16092865). Based on a literature review a small amount of articles have been published on candelalide A.
