These compounds are interesting and serves as novel potential pharmaceuticals in treating several diseases because of its profound biological activities. 3-APs polymers are potent anticholinesterase agents, in addition, they show hemolytic and cytotoxic activities. More than 70 structurally different 3-APs have been isolated from marine sponges. However, not all such sponges contain 3-AP compounds. Variation in content of 3-APs has been detected even within a single sponge species collected from different geographical area. Although 3-APs look structurally quite simple, the structure elucidation by NMR spectroscopy is complicated by the fact that most of the methylene groups in the alkyl chains show the same chemical shift. Therefore, the 3-APs are an ideal test case for a combined approach of NMR spectroscopy and mass spectrometry."@en }
