| Description | (1S,2S,5S,7S,10R,11S,14S,15R)-2-formyl-11-hydroxy-15-methyl-14-(2-oxo-2H-pyran-5-yl)-5-{[(2S,3R,4S,5R,6R)-3,4,5-trihydroxy-6-methyloxan-2-yl]oxy}tetracyclo[8.7.0.0²,⁷.0¹¹,¹⁵]Heptadecan-7-yl acetate 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. Lanceotoxin B is found in Kalanchoe lanceolata and Kalonchoe lanceolata. Based on a literature review very few articles have been published on (1S,2S,5S,7S,10R,11S,14S,15R)-2-formyl-11-hydroxy-15-methyl-14-(2-oxo-2H-pyran-5-yl)-5-{[(2S,3R,4S,5R,6R)-3,4,5-trihydroxy-6-methyloxan-2-yl]oxy}tetracyclo[8.7.0.0²,⁷.0¹¹,¹⁵]Heptadecan-7-yl acetate. |
