- Sealgamide: An Antitrypanosomal Lipopeptide Isolated from a Marine sp. Cyanobacterium.

Elucidation of its structure was challenging due to signal overlap caused by conspicuous rotamers but was ultimately achieved through partial hydrolysis and subsequent spectroscopic analyses. Sealgamide () exhibited moderate antitrypanosomal activity against (IC 2.9 μM) while showing no antimalarial activity (IC > 25 μM) or cytotoxicity (IC > 30 μM). Furthermore, we discovered that an artificial C-terminal methyl ester analogue () exhibited notably enhanced antiparasitic activity.
