Common NameIsopaynantheine
DescriptionIsopaynantheine belongs to the class of organic compounds known as corynanthean-type alkaloids. These are alkaloids with a structure based on the corynanthean nucleus, which is a tetracycle characterized by an indole fused to a quinolizidine. Additionally, the quinolizidine ring system is substituted to a 2-methylpropyl group and one ethyl group. Isopaynantheine was first documented in 2011 (PMID: 21450536). Based on a literature review a significant number of articles have been published on Isopaynantheine (PMID: 24169379) (PMID: 34213886) (PMID: 32597657) (PMID: 35468648) (PMID: 35335999) (PMID: 24659356).
