Amphimedonoic acid and psammaplysene E, novel brominated alkaloids from Amphimedon sp.

Abstract : Examination of the CH2Cl2-MeOH (1:1) extract from the Madagascan sponge Amphimedon sp. highlighted two new brominated alkaloids, amphimedonoic acid (1) and psammaplysene E (2), along with the known 3,5-dibromo-4-methoxybenzoic acid (3). Their structures were elucidated by 1D and 2D NMR spectroscopy and HRESIMS data.
