Natural Product Identification
Common NameTylocrebrine
DescriptionTYLOCREBRINE belongs to the class of organic compounds known as phenanthroindolizidines. These are aromatic polycyclic compounds containing the phenanthroindolizidine skeleton, which is structurally characterized by an indolizidine and a phenanthrene, where the indolizidine is fused to the second benzene ring of a phenanthrene. Tylocrebrine is found in Ficus septica, Tylophora crebriflora and Tylophora floribunda. Tylocrebrine was first documented in 2005 (PMID: 16038551). Based on a literature review a small amount of articles have been published on TYLOCREBRINE (PMID: 26065924) (PMID: 24679059) (PMID: 21142214) (PMID: 20721818).
