  Absolute configuration of hydroazulenoid diterpenes based on circular dichroism

  摘要：

  The structure of a new hydroazulenoid diterpene, 9-epi-dictyol B(1), isolated from the brown alga Glossophora kuntii, was proposed on the basis of its spectral data and confirmed by chemical transformations. Absolute stereochemistry studies, based on the CD exciton chirality method, of the new diterpenoid 9-epi-dictyol B (1) as well as those of the previously reported dictyotadiol (6) led to the determination of the absolute configuration of the new compound 9-epi-dictyol B(1) and revisions of absolute configurations of previously reported diterpenoids dictyotriols C (2), D (3), and E (4), dictyol B (5), and dictyotadiol (6). The cause of previous erroneous results is discussed and indeed points to the extreme care which must be exercised by anyone using this method.

  A method of producing a bacterial replication host for a bacteriophage is provided, including selecting a bacterial species, strain, serotype or isolate that is different to a pathogenic bacterium as a host for replication of the bacteriophage. The bacterial replication host provides a safe, efficient non-toxic vehicle for propagating bacteriophage that are capable of infecting a pathogenic bacterium that is of a different bacterial species, strain, serotype or isolate to the replication host. The pathogenic bacterium may be of the genus Vibrio, Aeromonas or Pseudomonas. Particular Vibrio bacteria are pathogens of shrimps or prawns, such as Vibrio parahaemolyticus. The invention may therefore have particular applicability to aquaculture.
