Common Name(1r,2r,6s,7s,8r,16r,18r)-6,7-dihydroxy-8-(hydroxymethyl)-4,18-dimethyl-14-[(1e,3e)-nona-1,3-dien-1-yl]-16-(prop-1-en-2-yl)-9,13,15,19-tetraoxahexacyclo[12.4.1.0¹,¹¹.0²,⁶.0⁸,¹⁰.0¹²,¹⁶]nonadec-3-en-5-one
DescriptionExcoecariatoxin belongs to the class of organic compounds known as rhamnofolane and daphnane diterpenoids. These are diterpenoids with a structure based on one the rhamnofolane or daphnane skeleton. The rhamnofolane and daphnane skeletons are closely related, being formally derived from casbane by two cyclizations (6,10 and 5,14) followed by cleavage of the 1,15 (daphnane) or 2,15 (rhamnofolane) cyclopropane bonds. (1r,2r,6s,7s,8r,16r,18r)-6,7-dihydroxy-8-(hydroxymethyl)-4,18-dimethyl-14-[(1e,3e)-nona-1,3-dien-1-yl]-16-(prop-1-en-2-yl)-9,13,15,19-tetraoxahexacyclo[12.4.1.0¹,¹¹.0²,⁶.0⁸,¹⁰.0¹²,¹⁶]nonadec-3-en-5-one is found in Diarthron vesiculosum, Excoecaria cochinchinensis and Gnidia kraussiana. (1r,2r,6s,7s,8r,16r,18r)-6,7-dihydroxy-8-(hydroxymethyl)-4,18-dimethyl-14-[(1e,3e)-nona-1,3-dien-1-yl]-16-(prop-1-en-2-yl)-9,13,15,19-tetraoxahexacyclo[12.4.1.0¹,¹¹.0²,⁶.0⁸,¹⁰.0¹²,¹⁶]nonadec-3-en-5-one was first documented in 2012 (PMID: 22148316). Based on a literature review very few articles have been published on Excoecariatoxin.
