dc.description.abstractTwo novel pectenotoxins (PTXs), PTX-13 and -14, were isolated from extracts of Dinophysis acuta collected from the west coast of South Island, New Zealand. The compounds were identified as oxidized analogues of PTX-2 by NMR spectroscopic and LC-MS studies. PTX-13 (32R-hydroxyPTX-2) corresponds to the unidentified analogue PTX-11x reported by [Suzuki et al., 2003. Liquid chromatography-mass spectrometry of spiroketal stereoisomers of pectenotoxins and the analysis of novel pectenotoxin isomers in the toxic dinoflagellate Dinophysis acuta from New Zealand. J. Chromatogr. A 992, 141–150]. PTX-13 underwent slow deuteration at the 13β-position during NMR analysis. PTX-14 corresponds to the 32,36-dehydration product of PTX-13, and may be an artifact.en_NZ
