Orfamide A is the major component of a family of cyclic lipopeptides. It appears to be a selective antifungal agent and an inhibitor of the enzyme acetylcholinesterase. It has been studied due to its anti-inflammatory, anti-bacterial, and anti-cancer properties. Additionally, it has been employed to study the effects of Orfamide A inhibitors on cognitive function and memory.
