Two complex proline esters from the sea hare Stylocheilus longicauda.
Investigation of Stylocheilus longicauda led to the isolation of chlorinated metabolites, makalika ester (1) and makalikone ester (2). Also reported is the isolation of lyngbyatoxin A acetate (3). The structures of the new compounds are based on spectroscopic data obtained from 1D and 2D NMR experiments.
