New haliclamines E and F from the Arctic sponge Haliclona viscosa

Gesine Schmidt, Christoph Timm and Matthias Köck

The Arctic sponge Haliclona viscosa is a rich source of 3-alkyl pyridinium alkaloids. Herein, we report the identification of two new haliclamines from the crude extract of this sponge. Due to the lack of sponge material, identification relied on HR-LCMS measurements and comparison with synthetic compounds.
