New bioactive natural products from marine algae and cyanobacteria

Creator:: Sabry, Omar Mohamed
Abstract:: This thesis is an account of investigation on the natural products deriving from various marine algae and has resulted in the discovery of eleven novel bioactive metabolites. Isolation and characterization of these new molecules were carried out using different chromatographic techniques and by analyses of different spectroscopic data, respectively. Using...

Novel secondary metabolites from a Madagascar collection of Lyngbya majuscula

Creator:: Nannini, Christopher J.
Abstract:: Marine organisms produce a variety of secondary metabolites for defense, communication, and reproduction. While these uses are essential for the organisms' survival, marine natural products have demonstrated their value to human society as well. Asian countries used algae for centuries to treat or prevent illnesses as wide-ranging as cough, gout,...

Natural products studies of the marine cyanobacterium Lyngbya majuscula

Creator:: Sitachitta, Namthip
Abstract:: The marine cyanobacterium Lyngbya majuscula has proven to be extraordinarily rich in bioactive secondary metabolites. This dissertation describes the chemistry of L. majuscula collected from Grenada, Fiji and Papua New Guinea, and the biosyntheses of two L. majuscula metabolites, curacin A and barbamide. The chemical studies with a Grenada collection...

Natural products studies of the marine cyanobacteria Lyngbya semiplena and Lyngbya majuscula

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...
