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,...

Structure elucidation of bioactive natural products from Madagascar marine algae and cyanobacteria

Creator:: Andrianasolo, Eric Hajaniriana
Abstract:: This thesis is an investigation of the natural products deriving from marine algae and cyanobacteria and has resulted in the discovery of eleven new secondary metabolites. The structure elucidations of these new molecules were performed using a variety of spectroscopic techniques. Four new macrolides were isolated and characterized from the...

Bioactive secondary metabolites from marine algae and study of oxidized anandamide derivatives

Creator:: Yoo, Hye-Dong
Abstract:: My investigations of the natural products of marine algae have resulted in the discovery of several new secondary metabolites. Bioassay-guided fractionation led to the isolation of these new compounds and spectroscopic analysis was utilized in their structural characterization. Two new and potent antimitotic metabolites, curacins B and C, were isolated...

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...

Structure and biosynthesis of marine cyanobacterial natural products : development and application of new NMR methods

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...

Synthetic studies on indolic enamide natural products: 1. Total syntheses of coscinamide A, concinamide B and igzamide: 2. Synthetic studies towards the synthesis of halocyamine B

Creator:: Ma, Yuelong
Abstract:: The 3-substituded indolic enamide moiety has been found in many marine compounds over the past 20 years. These indolic enamides exhibit various biological properties such as cytotoxic, anthelmintic, antimicrobial and HW-inhibitory activities. Among these indolic enamides, some are (E)-enamides, like coscinamide A and coscinamide B, others are (Z)-configuration in their...
