4-{[(1r,2s,4r,6r,7r,10s,11s,14s,16r)-7,11-dimethyl-6-(6-oxopyran-3-yl)-3-oxapentacyclo[8.8.0.0²,⁴.0²,⁷.0¹¹,¹⁶]octadecan-14-yl]oxy}-4-oxobutanoic acid

Description

4-{[(1R,2S,4R,6S,7R,10S,11S,14S,16R)-7,11-dimethyl-6-(2-oxo-2H-pyran-5-yl)-3-oxapentacyclo[8.8.0.0²,⁴.0²,⁷.0¹¹,¹⁶]Octadecan-14-yl]oxy}-4-oxobutanoic acid 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. 4-{[(1r,2s,4r,6r,7r,10s,11s,14s,16r)-7,11-dimethyl-6-(6-oxopyran-3-yl)-3-oxapentacyclo[8.8.0.0²,⁴.0²,⁷.0¹¹,¹⁶]octadecan-14-yl]oxy}-4-oxobutanoic acid is found in Bufo gargarizans. Based on a literature review very few articles have been published on 4-{[(1R,2S,4R,6S,7R,10S,11S,14S,16R)-7,11-dimethyl-6-(2-oxo-2H-pyran-5-yl)-3-oxapentacyclo[8.8.0.0²,⁴.0²,⁷.0¹¹,¹⁶]Octadecan-14-yl]oxy}-4-oxobutanoic acid.
