Centrifugal Partition Chromatography, Microfabrication, and a Smartphone-based Detection Platform : Analytical Chemistry from Preparative-scale Separation to Micro-scale Analysis

Creator:: Boonloed, Anukul
Abstract:: Analytical chemistry is an area of chemistry primarily focused on the study and use of instruments for separation, identification, and quantification of an analyte of interest. Specifically, separation science within analytical chemistry often refers to the process of dividing mixtures into their small component parts based on differences in their...

Synthesis of metabolites from the ascomycetes : I. The synthesis and absolute configuration of leptosphaerin : II. Approaches to the synthesis of byssochlamic acid

Creator:: Pallenberg, Alexander J.
Abstract:: Part I. The total synthesis of (+)-leptosphaerin (2), a metabolite of the marine Ascomycete Leptosphaeria Oraemaris (Linder) was achieved, unambiguously establishing both the relative and absolute stereochemistry of this natural product. This synthesis also resolved the long-standing question of which of the isomeric structures 1 or 2 correctly represents the...

Approaches to the total synthesis of verrucarol

Creator:: Hill, David E. (David Edwin) 1954-
Abstract:: Verrucarol is the sesquiterpene portion of a number of macrocyclic di- and triesters of potential medicinal importance. In this study, a novel approach to the synthesis of this fungal metabolite is presented. An A-B-C route was investigated in which C-3 and C-4 of the C-ring were emplaced using a [2+2]...

Approaches to the synthesis of trichothecenes

Creator:: Kim, No-soo
Resource Type:: Dissertation
Full Text:: . White Trichothecenes are secondary fungal metabolites which have potential medicinal importance. In

Spalting Fungi : Genetic Identification, Material Interactions and Microscopical Characteristics of Extracted Pigments

Creator:: Vega Gutiérrez, Sarath Mercedes
Abstract:: Spalting fungi show strong potential as natural colorants on a variety of materials, specifically textiles and wood. Four species of spalting fungi are currently utilized in this manner: Scytalidium cuboideum, which produces a red pigment called draconin red, Scytalidium ganodermophthorum, that produces an unknown yellow pigment, and Chlorociboria aeruginosa and...
Resource Type:: Dissertation

Natural product synthesis via cyclobutanes : part I, Asymmetric synthesis of (+)-byssochlamic acid, part II, An approach to the nootropic agent huperzine A

Creator:: Kim, Jungchul
Abstract:: PART I. Asymmetric syntheses of both natural (+)- and nonnatural (-)-byssochlamic acid via a [2+2] photoaddition-cycloreversion strategy are described. X-ray crystallographic analysis of the cyclohexylamine salt 99 showed that the structure of the monomethyl ester 100 from esterase hydrolysis of 44 was originally misassigned as 56. The enantiomeric relationship of...

Metabolomic Profiling of Natural Products from Two Tolypocladium Fungal Species as Part of An Evolutionary Genomics Study

Creator:: Dickey, Bailey J.
Abstract:: This thesis describes an investigation of the natural products chemistry of two fungal species of the genus Tolypocladium. Natural products are small organic molecules that are considered non-essential for cell growth and reproduction, and thus part of secondary metabolism. Chemical profiling of these secondary metabolites using a combination of high-performance...
Resource Type:: Masters Thesis
Full Text:: important fungal metabolite. In the 1970’s, a Swiss pharmaceutical company called Sandoz Ltd. (Basel) was

Toxicity of Fungal Pigments from Chlorociboria spp. and Scytalidium spp.

Creator:: Almurshidi, Badria H.
Abstract:: Commercial methodologies for producing fungal pigments are of worldwide interest due to the desire to move away from synthetic dyes. Chlorociboria species and Scytalidium species have been reported to produce sufficient yields of pigments for commercial production and have attracted special attention because of their use in spalted wood applications....

Studies towards the total syntheses of (+)-phomactins A, D and G

Creator:: Schwartz, Keith D.
Abstract:: Studies towards the total synthesis of (+)-Phomactin A (1), D (6), and G (9), fungal metabolites with unique molecular architecture and pronounced biological activity, are described. These studies resulted in the synthesis of advanced intermediates 354 and 356, which contain all of the carbon atoms of 1, 6 and 9....
