For the first time, the macrocyclic monomeric 3-alkyl pyridinium alkaloid with an alkyl chain of 13 methylene groups, haliclocyclin C (1), could be identified from a natural source in the crude extract of the Arctic sponge Haliclona viscosa. Structure elucidation was carried out by comparison of the natural product with the corresponding synthetic compound.
