Abstract

(Chemical Equation Presented) Two new serinolipid derivatives, shishididemniols A (1) and B (2), were isolated as antibacterial constituents of a tunicate of the family Didemnidae. The structure of 1 was elucidated by interpretation of spectral data and the application of the modified Mosher method to 1 and its suitable degradation products. Compound 2 was the chlorohydrin of 1. Compounds 1 and 2 exhibited antibacterial activity against fish pathogenic bacterium Vibrio anguillarum.
