Title: Structural elucidation of secondary metabolites from Hypoxylon fragiforme, using high resolution mass spectrometry and gas-phase ion-molecule reactions SUMMARY Fungi produce a wide variety of biologically active compounds/metabolites.

Plants: a source of biologically active secondary metabolites Plants have formed the basis for traditional medicine systems which have been used for thousands of years in countries such as. The terpenes, or terpenoids, constitute the largest class of secondary metabolites.

Most of the diverse substances of this class are insoluble in water. They are synthesized from acetyl-CoA or its glycolytic intermediates. After discussing the biosynthesis of terpenes File Size: 3MB.

Currently, natural products, especially plant secondary metabolites such as isoprenoids, phenolics and alkaloids, have been demonstrated to be the leading providers of novel anticancer agents. In this book, firstly a general introduction is given on plant secondary metabolism, followed by an overview of the possible approaches that could be used to alter secondary metabolite pathways.

secondary metabolism is blurred. Based on their biosynthetic origins, plant natural products can be divided into three major groups: the terpenoids, the alkaloids, and the phenylpropanoids and allied pheno-lic compounds.

All terpenoids, including both primary metabolites and more t secondary. Natural products have historically been a rich source of “lead compounds” in drug discovery.

The investigation of terrestrial plants and marine organisms aimed at searching new biologically active compounds is a central issue of this kind of studies, trough structure elucidation combined with biological tests. The secondary metabolites of plants were once considered to be waste products - today, their true value is understood.

New methods of separation and structural elucidation, and advances in the investigation of biochemical activities, have increased our understanding of secondary metabolites. Plant secondary metabolites have been a fertile area of chemical investigation for many years, driving the development of both analytical chemistry and of new synthetic reactions and methodologies.

The subject is multi-disciplinary with chemists, biochemists and plant Price: $ elucidation and applications. The review provides an insight into the diversity of plant secondary metabolites, their classification, biosynthesis, biological properties and their multidimensional prospective in plant life.

I thank all the people during the years at the Division of Structural Elucidation Chemistry and at the Plant Secondary Metabolism group in.

We introduce a cheminformatics approach that combines highly selective and orthogonal structure elucidation parameters; accurate mass, MS/MS (MS2), and NMR into a single analysis platform to accurately identify unknown metabolites Cited by: Costs of Secondary metabolism (ATP / NADPH2 consumption) - Biosynthesis of precursors and secondary metabolites - Transport and storage - Formation of specialized storage compartments (e.g.

trichomes) - Synthesis. F Structure Elucidation. Structure elucidation of the bioactive constituent depends almost exclusively on the application of modern instrumental methods, particularly high-field NMR with cryoprobe systems where the level of compound is in the sub-milligram range, and MS n.

These powerful techniques, coupled in some cases with selective chemical manipulations. Natural products have historically been a rich source of “lead compounds” in drug discovery. The investigation of terrestrial plants and marine organisms aimed at searching new biologically active compounds is a central issue of this kind of studies, trough structure elucidation combined with biological.
