Palmadorins A-C, diterpene glycerides from the antarctic nudibranch austrodoris kerguelenensis

Academic Article


  • The nudibranch Austrodoris kerguelenensis is distributed widely around the Antarctic coast and continental shelves. Earlier collections from. McMurdo Sound and the Weddell Sea shelf have afforded a suite of diterpene glyceride esters, a compound class implicated as a chemical defense in nudibranchs. The present chemical investigation of A. kerguelenensis collected near Palmer Station on the Western Antarctic Peninsula has revealed additional examples, palmadorins A-C (1-3), as the first three members of a new series of clerodane diterpenes. In this paper we describe their isolation, structure elucidation, and stereochemical analysis using a combination of one- and two-dimensional NMR spectroscopy and wet chemical methods. © 2010 American Chemical Society and American Society of Pharmacognosy.
