PAVONININS, SHARK-REPELLING AND ICHTHYOTOXIC STEROID N-ACETYLGLUCOSAMINIDES FROM THE DEFENSE SECRETION OF THE SOLE PARDACHIRUS PAVONINUS (SOLEIDAE)

Article abstract of DOI:10.1016/S0040-4020(01)96470-1

Six steroid N-acetylglucosaminides, pavoninins-1 to -6, have been isolated from the defense secretion of the sole P.pavoninus guided by ichthyotoxicity and hemolytic activity, and their structures determined to be 1-6 by spectroscopic studies and chemical correlations.The pavoninins are considered to be the factors responsible for the repellent property of the sole against predatory fishes.
