Tellimagrandin II is an isomer of punicafolin or nupharin A, but the hexahydroxydiphenoyl group is not attached to the same hydroxyl groups in the glucose molecule.
The compound shows anti-herpesvirus properties.[1]
It is formed by oxidation of pentagalloyl glucose in Tellima grandiflora by the enzyme pentagalloylglucose: O(2) oxidoreductase, a laccase-type phenol oxidase.[2]
It is further oxidized to casuarictin, a molecule formed via oxidative dehydrogenation of 2 other galloyl groups in Casuarina and Stachyurus species.[3]
It is laccase-catalyzed dimerized to cornusiin E in Tellima grandiflora.[4][5]
It has an extremely weak basic(essentially neutral) compound. The compound shows anti-herpesvirus properties.
