Biological and structural characterization of the Mycobacterium smegmatis nitroreductase NfnB, and its role in benzothiazinone resistance

Stewart Cole, Giulia Manina, Joao Pedro De Almeida Neres

Summary Tuberculosis is still a leading cause of death in developing countries, for which there is an urgent need for new pharmacological agents. The synthesis of the novel antimycobacterial drug class of benzothiazinones (BTZs) and the identification of t ...

The MycoBrowser portal: a comprehensive and manually annotated resource for mycobacterial genomes

Stewart Cole, Jocelyne Lew, Adamantia Kapopoulou

In this paper, we present the MycoBrowser portal (http://mycobrowser.epfl.ch/), a resource that provides both in silico generated and manually reviewed information within databases dedicated to the complete genomes of Mycobacterium tuberculosis, Mycobacter ...

Use of consensus sequences for the design of high density resequencing microarrays: the influenza virus paradigm

Stewart Cole, Iain Old

BACKGROUND: A resequencing microarray called PathogenID v2.0 has been developed and used to explore various strategies of sequence selection for its design. The part dedicated to influenza viruses was based on consensus sequences specific for one gene gene ...

Antimalarial and antitubercular nostocarboline and eudistomin derivatives: synthesis, in vitro and in vivo biological evaluation

Simone Bonazzi, Luc Patiny, Rosario Scopelliti, Karl Gademann, Stewart Cole

The synthesis of nine nostocarboline derivatives with substitutions of the 2-methyl group by alkyl, aryl and functionalized residues, 10 symmetrical bis cationic dimers linking 6-Cl-norharmane through the 2-position and fifteen derivatives of the marine al ...

Sigma Factor F does not Prevent Rifampin Inhibition of RNA Polymerase or Cause Rifampin Tolerance in Mycobacterium tuberculosis

Stewart Cole, Claudia Sala, Florence Pojer, Sophie Magnet, Jeffrey Chen, Ruben Hartkoorn

The tolerance of Mycobacterium tuberculosis to anti-tuberculosis drugs is a major reason for the lengthy therapy needed to treat a tuberculosis infection. Rifampin is a potent inhibitor of RNA polymerase (RNAP) in vivo, but has been shown to be less effect ...

TubercuList - 10 years after

Stewart Cole, Jocelyne Lew, Adamantia Kapopoulou

TubercuList (http://tuberculist.epfl.ch/), the relational database that presents genome-derived information about H37Rv, the paradigm strain of Mycobacterium tuberculosis, has been active for ten years and now presents its twentieth release. Here, we descr ...

Mycobacterium leprae: genes, pseudogenes and genetic diversity

Stewart Cole, Pushpendra Singh

Leprosy, which has afflicted human populations for millenia, results from infection with Mycobacterium leprae, an unculturable pathogen with an exceptionally long generation time. Considerable insight into the biology and drug resistance of the leprosy bac ...

Transcriptional regulation of lipid homeostasis in mycobacteria

Stewart Cole, Claudia Sala

Mycolic acids are major components of the cell envelope of mycobacteria, such as Mycobacterium tuberculosis, and play an important role in its architecture, impermeability and interaction with the environment. Synthesis of mycolic acids is carried out by t ...

SPACE: the spectroscopic all-sky cosmic explorer

Rachel Grange, Herbert Shea, Stewart Cole, Fabio Finelli, Jean-Paul Richard Kneib, Yi Wang

We describe the scientific motivations, the mission concept and the instrumentation of SPACE, a class-M mission proposed for concept study at the first call of the ESA Cosmic-Vision 2015–2025 planning cycle. SPACE aims to produce the largest three-dimensio ...

Mycobacterium leprae genotype amplified from an archaeological case of lepromatous leprosy in Central Asia

Stewart Cole

We have amplified Mycobacterium leprae DNA from the skeleton of an adult human female exhibiting signs of lepromatous leprosy (LL). The remains were excavated from the site of Devkesken 6 on the Ustyurt plateau of Uzbekistan and date to between the 1st and ...

Dissecting regulatory networks in host-pathogen interaction using chIP-on-chip technology

Stewart Cole, Claudia Sala

Understanding host-microbe interactions has been greatly enhanced by our broadening knowledge of the regulatory mechanisms at the heart of pathogenesis. The "transcriptomics" approach of measuring global gene expression has identified genes involved in bac ...

Diversity-oriented synthesis of furo[3,2-f]chromanes with antimycobacterial activity

Stewart Cole

We previously reported the synthesis and the antimycobacterial activity of 4-(7,7-dimethyl-7H-furo[3,2-f]chromen-2-yl)pyridine. From this result, we sought to design simple synthetic accesses to related structures allowing the preparation of a diverse set ...

Comparative genomic and phylogeographic analysis of Mycobacterium leprae

Stewart Cole, Jacques Rougemont, Alexandre Gattiker, Philippe Busso, Pushpendra Singh

Reductive evolution and massive pseudogene formation have shaped the 3.31-Mb genome of Mycobacterium leprae, an unculturable obligate pathogen that causes leprosy in humans. The complete genome sequence of M. leprae strain Br4923 from Brazil was obtained b ...

Genome-wide regulon and crystal structure of BlaI (Rv1846c) from Mycobacterium tuberculosis

Stewart Cole, Claudia Sala

Comparative genomics with Staphylococcus aureus suggested the existence of a regulatory system governing beta-lactamase (BlaC) production in Mycobacterium tuberculosis. The crystal structure of Rv1846c, a winged helix regulator of previously unknown functi ...

High content screening identifies decaprenyl-phosphoribose 2' epimerase as a target for intracellular antimycobacterial inhibitors

Stewart Cole, Ha Pham

A critical feature of Mycobacterium tuberculosis, the causative agent of human tuberculosis (TB), is its ability to survive and multiply within macrophages, making these host cells an ideal niche for persisting microbes. Killing the intracellular tubercle ...

A comprehensive survey of single nucleotide polymorphisms (SNPs) across Mycobacterium bovis strains and M. bovis BCG vaccine strains refines the genealogy and defines a minimal set of SNPs that separate virulent M. bovis strains and M. bovis BCG strains

Stewart Cole, Swapna Uplekar

To further unravel the mechanisms responsible for attenuation of the tuberculosis vaccine Mycobacterium bovis BCG, comparative genomics was used to identify single nucleotide polymorphisms (SNPs) that differed between sequenced strains of Mycobacterium bov ...

Benzothiazinones kill Mycobacterium tuberculosis by blocking arabinan synthesis

John McKinney, Stewart Cole, Neeraj Dhar, Claudia Sala, Elizabeth Fullam, Giulia Manina

New drugs are required to counter the tuberculosis (TB) pandemic. Here, we describe the synthesis and characterization of 1,3-benzothiazin-4-ones (BTZs), a new class of antimycobacterial agents that kill Mycobacterium tuberculosis in vitro, ex vivo, and in ...
