| Description | 20R,21-Epoxyresibufogenin belongs to the class of organic compounds known as bufanolides and derivatives. These are steroid lactones containing a pyran-2-one moiety linked to the C17 atom of a cyclopenta[a]phenanthrene derivative. 20S,21-epoxyresibufogenin is found in Ch'an Su. 20S,21-epoxyresibufogenin was first documented in 2002 (PMID: 12141860). Based on a literature review a small amount of articles have been published on 20R,21-Epoxyresibufogenin (PMID: 20599324) (PMID: 17451794). |
