Common Name(1r,5r,8r)-8-[(1s,2r,5s,7s,8r,10s,11s,14r,15s)-8-hydroxy-2,15-dimethyl-3-oxopentacyclo[8.7.0.0²,⁷.0⁵,⁷.0¹¹,¹⁵]heptadecan-14-yl]-5-methyl-4-methylidene-2,6-dioxabicyclo[3.3.1]nonan-3-one
DescriptionWithawrightolide belongs to the class of organic compounds known as steroid lactones. These are sterol lipids containing a lactone moiety linked to the steroid skeleton. (1r,5r,8r)-8-[(1s,2r,5s,7s,8r,10s,11s,14r,15s)-8-hydroxy-2,15-dimethyl-3-oxopentacyclo[8.7.0.0²,⁷.0⁵,⁷.0¹¹,¹⁵]heptadecan-14-yl]-5-methyl-4-methylidene-2,6-dioxabicyclo[3.3.1]nonan-3-one is found in Datura wrightii. It was first documented in 2013 (PMID: 23252848). Based on a literature review very few articles have been published on Withawrightolide.
