| two (z)-dehydrobutyrine-containing microcystins from a hepatotoxic bloom of oscillatoria agardhii from soulseat loch, scotland. | two (z)-dehydrobutyrine(dhb)-containing microcystins, [d-asp3, (z)-dhb7]microcystin-htyr (1) and [d-asp3, (z)-dhb7]microcystin-lr (2), were isolated from a hepatotoxic bloom of the cyanobacterium oscillatoria agardhii from a freshwater lake in scotland. the geometrical structure of the dhb units in the microcystins was determined as z on the basis of noe and roesy experiments. | 1998 | 9644085 |
| identification of anatoxin-a in benthic cyanobacteria (blue-green algae) and in associated dog poisonings at loch insh, scotland. | dog deaths occurred in 1990 and 1991 after the animals drank water containing blooms of benthic cyanobacteria along the shoreline of loch insh, scotland. signs of poisoning in the affected animals and the high neurotoxicity of bloom extracts in laboratory bioassays indicated acute poisoning due to cyanobacterial neurotoxin(s). the neurotoxic blooms consisted largely of benthic oscillatoria species which were also observed in the stomach contents of the poisoned dogs. stomach contents were also n ... | 1992 | 1440622 |
