Creator:: Nogle, Lisa Marie
Abstract:: This thesis details my investigations of marine cyanobacterial natural products that resulted in the discovery of thirteen new secondary metabolites, the isolation of over fifteen previously reported metabolites and the biosynthetic investigation of two additional cyanobacterial compounds. Two novel lipopeptides were identified from a Lyngbya majuscula and Schizothrix sp. assemblage...

Creator:: Marquez, Brian L.
Abstract:: This thesis is an account of my explorations into the field of natural products chemistry. These investigations led to the discovery of several novel secondary metabolites isolated from the marine cyanobacterium Lyngbya majuscula. In addition, biosynthetic investigations were undertaken using stable isotope-labeled precursors. The dominant role that NMR spectroscopy plays...

Creator:: Han, Bingnan
Abstract:: This thesis details my investigations of marine cyanobacterial natural products that resulted in the discovery of eighteen new secondary metabolites. Isolation and characterization of these unique molecules were carried out using different chromatographic techniques and by careful analyses of 1D and 2D NMR data, respectively. Preliminary bioassays of the crude...

Creator:: Ramaswamy, Aishwarya V.
Abstract:: Cyanobacteria are rich in biologically active secondary metabolites, many of which have potential application as anticancer or antimicrobial drugs or as useful probes in cell biology studies. A Jamaican isolate of the marine cyanobacterium, Lyngbya majuscula was the source of a novel antifungal and cytotoxic secondary metabolite, hectochlorin. The structure...

Creator:: Milligan, Kenneth Edward
Abstract:: This thesis describes investigations of marine algal secondary metabolites, with particular interest in their biomedical and agrichemical potential. Invaluable in such pursuits have been the access and application of advanced spectroscopic techniques, such as NMR, and the ability to assess the biological activity of the algal samples in a variety...
