| Common Name | Picrotin |
|---|
| Description | Picrotin belongs to the class of organic compounds known as furopyrans. These are organic polycyclic compounds containing a furan ring fused to a pyran ring. Furan is a five-membered aromatic ring with four carbon atoms and one oxygen atom. Pyran a six-membered heterocyclic, non-aromatic ring, made up of five carbon atoms and one oxygen atom and containing two double bonds. Picrotin 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. Picrotin is found in Anamirta cocculus , Anamirta paniculata, Cocculus indicus, Diphylleia grayi, Juniperus sabina and Podophyllum peltatum . Picrotin was first documented in 2003 (PMID: 12660352). Based on a literature review a significant number of articles have been published on picrotin (PMID: 29069925) (PMID: 23397268) (PMID: 23079787) (PMID: 21059362) (PMID: 17405877) (PMID: 17714449). |
