Abstract

A new pyridinium derivative, polyaxibetaine (3), has been isolated from the marine sponge Axinella polypoides, together with two known modified amino acids, 1 and 2. The planar structure of compound 3 has been elucidated by spectroscopic methods; definition of the absolute configuration of compounds 1-3 has been carried out through ECD studies.
