| Common Name | epiquinine |
|---|
| Description | Epiquinine, also known as apo quinidine or quincardine, belongs to the class of organic compounds known as cinchona alkaloids. These are alkaloids structurally characterized by the presence of the cinchonan skeleton, which consists of a quinoline linked to an azabicyclo[2.2.2]Octane moiety. epiquinine is found in Cinchona pubescens. epiquinine was first documented in 2012 (PMID: 24061297). Based on a literature review a small amount of articles have been published on Epiquinine (PMID: 32214482) (PMID: 28581297) (PMID: 22869567) (PMID: 22276975). |
