Abstract:
Analogues of Antibacterial Natural Products Elizabeth Anne Heaviside, St Catherine’s College, University of Oxford DPhil Thesis, Trinity Term 2012 This thesis is concerned with the synthesis and biological evaluation of structural mimics for the natural products 16-methyloxazolomycin and lemonomycin which display potent biological activity including antibacterial and antitumour activity. Chapter 1 explores methods and approaches to the discovery of new antibacterial drugs and the challenges faced in this respect. It also gives an overview of the properties of the natural products investigated in the following chapters and summarises previous synthetic approaches to these molecules published in the scientific literature. Chapter 2 describes the work carried out towards the synthesis of the diazabicyclo[3.2.1]octane unit of the tetrahydroisoquinoline antitumour antibiotic lemonomycin. The intended retrosynthesis of the natural product led to a 2,5-disubstituted pyrrolidine bearing a 1ʹ-amino functional group; a series of routes were explored for the synthesis of this unit. Using (S)-pyroglutamic acid, strategies using Eschenmoser and thiolactim ether coupling reactions were investigated. A sequence based on the formation of a pyrrolidine ring from the cyclisation of an appropriately substituted oxime ether derived from L-phenylalanine was then implemented but a competing Beckmann rearrangement/Grob fragmentation prevented access to the desired heterocycle. Preliminary investigations were also carried out on the modification of cyclic imines derived from oxime ethers which did not undergo Beckmann rearrangement. Chapter 3 describes the synthesis of a library of densely functionalised tetramic acid and pyroglutamate mimics for the right-hand fragment of 16-methyloxazolomycin, and their coupling with a gem-dimethylamide unit mimicking the middle fragment of the natural product. Tetramates were accessed through the Dieckmann cyclisation of N-acyloxazolidines and were derivatised with various alkyl halides. The pyroglutamates were accessed via the highly diastereoselective aldol cyclisation of N-acyloxazolidines formed by the amide coupling of a threonine derived oxazolidine and β-keto-acids. A series of β-keto-acids were synthesised through the acylation and subsequent ring-opening/decarboxylation reaction of Meldrum’s acid. The formation of right-hand/middle fragment adducts was explored using cycloaddition, alkylation and Sonogashira chemistry before a Wittig protocol led to the formation of adducts (E)- and (Z)- 402 and 403. Biological evaluation of the compounds synthesised in this chapter was carried out using both broth and hole-plate bioassays and active compounds were identified. Of particular note was that the Wittig adducts displayed a higher level of activity against Gram-negative E. coli than either the pyroglutamate or amide motifs alone.

Abstract:
Natural products as sources of novel therapeutic agents experienced a steady increase from around the turn of the twentieth century until it peaked in the 1970s and 1980s. However since this time pharmaceutical research in natural products has experienced a decline. Despite this trend the natural products industry now seems to be experiencing a revival of sorts. This thesis represents a continuation of the work on the isolation and structure elucidation of potential drug leads from terrestrial fungal sources that the natural products group at the University of Canterbury is engaged in. The known compound, pseurotin A (2.7) and two novel diastereomers, pseurotin A2 (2.8) and pseurotin A3 (2.9) were isolated from the extract of a Penicillium sp. of fungus collected from the foreshore of a beach in Vancouver, Canada. The absolute stereochemistry of pseurotin A2 and proposed absolute stereochemistry for A3 were elucidated using a combination of X-ray crystallography (A2 only), circular dichrosim, oxidative cleavage reactions, and J2-resoved 2D NMR experiments. The extract of an as yet unidentified endophytic fungus has yielded eight novel compounds related to the spirobisnaphthalene class of compounds. These eight compounds fall into to distinct groupings. The spiro-mamakones, distinguished by a structurally unprecedented oxygenated spiro-nonene skeleton, comprise five compounds, spiro-mamakones A-E (3.11, 3.15-3.18). In addition to these naturally occurring compounds, the semi-synthetic compounds, 4-oxo-spiro-mamakone A (3.12) and O-acetyl-spiro-mamakone A (3.21), were also synthesised. spiro-Mamakone A was found to be racemic, while X-ray crystallography and optical rotation revealed spiro-mamakone C (3.15) to be present as an enantiomeric mixture (4S*, 5S*, 9R*). Unfortunately the enantiomeric excess was unable to be elucidated. NOE experiments revealed spiro-mamakone B (3.16) to have the relative stereochemistry 4S*, 5S*, 9S*. The relative stereochemistry of spiro-mamakones D (3.17) (4S*, 5S*, 8S*, 9S*) and E (3.18) (4S*, 5S*, 8S*, 9R*) was proposed from comparison of coupling constant calculations from energy-minimised models with those of the experimentally determined values. The second group, comprising three novel compounds named the mamakunoic acids, mamakunoic acid A-C (3.8, 3.7, 3.10), are characterised by their acid substituted dihydro benzofuran system. The low yield obtained of these compounds, unfortunately prevented their stereochemical elucidation. In addition to structure elucidation, biosynthetic studies on spiro-mamakone A and mamakunoic acid B were also carried out. Analysis of the NMR spectra derived from spiro-mamakone A, labelled with isotopic acetate, revealed a situation complicated by the presence of isotopomers and racemisation, resulting in NMR spectra that were somewhat anomalous in appearance. These irregularities however, were resolved leading to the proposal that spiro-mamakone A was derived from a dihydroxynaphthalene (DHN) intermediate, which proceeds through to spiro-mamakone via an epoxide intermediate. Despite problems with purity and low yields of isotopically labelled mamakunoic acid B, it was proposed that like spiro-mamakone A, it proceeded via a DHN intermediate. The extract derived from a Malaysian Scleroderma sp. was found to contain a new dichlorinated pulvinic acid derivative, methyl-3',5'-dichloro-4,4'-di-O-methylatromentate (4.14), the structure of which was confirmed by X-ray crystallography. In addition three previously reported compounds, 4,4'-dimethoxyvulpinic acid (4.11), methyl-3'-chloro-4,4'-di-O-methylatromentate (4.12) and methyl-4,4'-dimethoxyvulpinate (4.13), were also isolated. The extract of another, as yet unidentified endophytic fungus was found to contain the new acetogenin, 1,5-dihydroxy-6-(2-hydroxyethyl)-3-methoxyacetophenone (5.7), differing from the known compound, 2,4-dihydroxy-6-(2-hydroxyethyl)-3-methoxyacetophenone (5.8) only by virtue of the substitution pattern. The structure of 5.7 was confirmed by X-ray crystallography. The implementation of efficient dereplication procedures is paramount for those working in the field of natural products. The recent advances that have been made in the dereplication process in the natural products group at the University of Canterbury are given using examples from this research and where necessary from other group members.

Abstract:
Compounds from the marine environment exhibit a wide variety of biological activities, and thus hold much promise as potential drugs. The halichondrins, isolated from the Kaikoura sponge Lissodendoryx sp. are no exception to this, demonstrating potent anticancer activity. Novel cytotoxic compounds have also been isolated from the Chatham Rise sponge Lamellomorpha strongylata. Knowledge of the cellular origins of such compounds is desirable, in order to establish if the sponge or associated micro-organisms are producing the compounds of interest. Siderophores are also important molecules, which are produced on demand by bacteria in order to obtain sufficient iron necessary for their growth. Knowledge of the biosynthesis of these compounds has potential for the control of undesirable bacteria, such as the anthrax-causing pathogen Bacillus anthracis. Cell separation studies have been carried out on Lamellomorpha strongylata, locating a swinholide in sponge-associated filamentous bacteria and theonellapeptolides in sponge-associated unicellular bacteria. A microscopic analysis of dissociated cells from Lissodendoryx sp. was also undertaken. The structures of four new halichondrins (3.13 - 3.16), isolated from Lissodendoryx sp., have been determined from spectral data. All of these compounds are very similar to known B series halichondrins, with differences occurring only beyond carbon 44. As biological activity has been shown to be derived from the portion of the molecule between carbons 1 and 35, they all retain good activity in the P388 assay as expected. A new siderophore, petrobactin sulfonate (4.2), was characterised, along with three cyclic imide siderophore derivatives (4.3 - 4.5). Petrobactin sulfonate is the first marine siderophore containing a sulfonated 3,4-dihydroxy aromatic ring. The structures were elucidated from spectral data, resulting in a revision of the NMR assignments of petrobactin.

Abstract:
Obligately anaerobic bacteria of the genus Bacteroides are important and abundant inhabitants of the rumen and hind gut of mammals. They are the most numerous group in the rumen and play a major role in fibre degradation with the rumen. They are phylogenetically remote from the better studied groups of facultatively anaerobic gut bacteria (eg. enterobacteria), but are closely related to the colonic Bacteroides. Interstrain conjugal transfer of a plasmid, pRRI4 (coding for tetracycline (Tc) resistance), from the multiple plasmid bearing B.ruminicola strain 223/M2/7 to F101, a rifampicin resistant mutant of B.ruminicola B 14, was demonstrated. pRRI4 was demonstrated to be self transmissible and carried the genes coding for TcR in B.ruminicola. Transformation of B.ruminicola F101 to TcR with pRRI4 was achieved using electroporation at frequencies up to 106 per mug DNA. Four other B.ruminicola strains were not transformed with this plasmid nor was a strain of B.uniformis. Similar procedures gave transformation of B.uniformis strains, but not B.ruminicola strains, with the E.coli:Bacteroides shuttle vectors pDP1 and pE5-2 at frequencies up to 107 per mug DNA. A nuclease assay was developed to determine the nuclease activity of a number of rumen bacteria and high nuclease activity in all B.succinogenes and five B.ruminicola strains was demonstrated. E.coli and B.uniformis strains were also transformed using electroporation by the shuttle vector, pRRI207, which has been constructed from a cryptic B.ruminicola plasmid (pRRI2, 3.4kbp) cut with EcoRI* , an E.coli vector plasmid (pHG165, 3.37kbp) carrying the pUC8 multiple cloning site, and the 4.2kbp Cc-EmRTc R* EcoRI region of pDP1. pRRI207 is capable of transforming B.uniformis, B.distasonis and B.ruminicola to clindamycin (Cc) resistance and E.coli to TcR (only expressed aerobically), and was the only construct from eleven different constructs obtained based on pRRI2 able to do so.

Halogenated natural products are common and serve roles as hormones, pesticides, antibiotics, and anti-tumor agents. The incorporation of a halogen atom into an organic scaffold can tune the molecule's potency and selectivity, making halogenation an important tailoring reaction. To understand the mechanisms of enzymatic halogenation of natural products, X-ray crystallography was used to solve structures of enzymes from two classes of halogenases, the flavin-dependent halogenases and the non-heme iron dependent halogenases. Structures of the flavin-dependent tryptophan 7-halogenase RebH from Lechevalieria aerocolonigenes, involved in rebeccamycin biosynthesis, were solved by molecular replacement. These structures show distant flavin and L-Trp binding sites and identify the conserved residue Lys79 as a likely candidate for covalent modification to produce an enzyme-bound lysine chloramine intermediate. A lysine chloramine at this position would direct the chlorination reaction to the correct site on the substrate, which could account for the halogenase's observed regioselectivity. Crystal structures of the non-heme iron-dependent threonine 4-halogenase SyrB2 from Pseudomonas syringae, involved in syringomycin biosynthesis, were solved using selenomethionine labeling and single wavelength anomalous dispersion (SAD) techniques. These structures show an overall cupin or [beta]-sandwich fold and a novel iron binding motif containing a naturally occurring iron-chloride bond. The carboxylate ligand typically found in non-heme iron dependent hydroxylases is replaced by an alanine residue in the halogenases, opening a coordination site for the halide and suggesting a mechanism by which these enzymes accomplish halogenation instead of hydroxylation.
(cont)The final chapter of this thesis reviews the known classes of halogenating enzymes and examines questions of halide binding and selectivity from the perspective of protein structure.

Arguments in favour of thermo- and pyrochemical methods for the deep processing of various natural and artificial raw materials using liquation melting, plasma chemistry and pyrolysis, are put forward. Examples, showing the use and efficiency of these methods for processing rare-metal resources, including recommendations for industrial mineral deposits to be exploited and waste from active mining companies, are supplied. The author recommends to revive and develop rare-metal production and to replace foreign products by Russian ones with regard for the increasing role of the state and applied science.
