It is an isomer of casuarictin. It is a highly active carbonic anhydrase inhibitor.[3]
Biosynthesis
In some plants including oak and chestnut, the ellagitannins are formed from 1,2,3,4,6-pentagalloyl-glucose and further elaborated via oxidative dehydrogenation (tellimagrandin II and casuarictin formations). After conversion of casuarictin to pedunculagin, the pyranose ring of the glucose opens and the family of compounds including casuariin, casuarinin, castalagin, and castalin, vescalagin and vescalin forms.[4][self-published source?]
