Synthesis and Antimycobacterial Activity of 2,1 '-Dihydropyridomycins

Dihydropyridomycins 2 and 3, which lack the characteristic enol ester moiety of the potent antimycobacterial natural product pyridomycin (1), have been prepared from L-Thr, R- and S-hydroxy isovaleric acid, and 3-pyridinecarboxaldehyde. The 2R isomer 2 sho ...

Advances in the development of new tuberculosis drugs and treatment regimens

Stewart Cole

Despite the introduction 40 years ago of the inexpensive and effective four-drug (isoniazid, rifampicin, pyrazinamide and ethambutol) treatment regimen, tuberculosis (TB) continues to cause considerable morbidity and mortality worldwide. For the first time ...

Phenotypic Profiling of Mycobacterium tuberculosis EspA Point Mutants Reveals that Blockage of ESAT-6 and CFP-10 Secretion In Vitro Does Not Always Correlate with Attenuation of Virulence

Stewart Cole, Anna De Graff Tischler, Neeraj Dhar, Florence Pojer, Jeffrey Chen, Ming Zhang, Jan Lars Rybniker

The EspA protein of Mycobacterium tuberculosis is essential for the type VII ESX-1 protein secretion apparatus, which delivers the principal virulence factors ESAT-6 and CFP-10. In this study, site-directed mutagenesis of EspA was performed to elucidate it ...

High-resolution transcriptome and genome-wide dynamics of RNA polymerase and NusA in Mycobacterium tuberculosis

Stewart Cole, Claudia Sala, Swapna Uplekar, Jacques Rougemont

To construct a regulatory map of the genome of the human pathogen, Mycobacterium tuberculosis, we applied two complementary high-resolution approaches: strand-specific RNA-seq, to survey the global transcriptome, and ChIP-seq, to monitor the genome-wide dy ...

Genome-wide comparison of medieval and modern Mycobacterium leprae

Stewart Cole, Philippe Busso, Pushpendra Singh, Andrej Benjak

Leprosy was endemic in Europe until the Middle Ages. Using DNA array capture, we have obtained genome sequences of Mycobacterium leprae from skeletons of five medieval leprosy cases from the United Kingdom, Sweden, and Denmark. In one case, the DNA was so ...

High-resolution detection of DNA binding sites of the global transcriptional regulator GlxR in Corynebacterium glutamicum

Stewart Cole, Claudia Sala, Swapna Uplekar

The transcriptional regulator GlxR has been characterized as a global hub within the gene-regulatory network of Corynebacterium glutamicum. Chromatin immunoprecipitation with a specific anti-GlxR antibody and subsequent high-throughput sequencing (ChIP-seq ...

Mycobacterium tuberculosis EspB binds phospholipids and mediates EsxA-independent virulence

Stewart Cole, Neeraj Dhar, Florence Pojer, Jeffrey Chen, Ming Zhang, Stefanie Boy-Röttger, Jan Lars Rybniker

The type-VII ESX-1 secretion apparatus, encoded by the esx-1 genetic locus, is essential for the export of EsxA and EsxB, two major virulence factors of Mycobacterium tuberculosis. ESX-1 also requires the products of the unlinked espACD operon for optimal ...

Application of High-Density DNA Resequencing Microarray for Detection and Characterization of Botulinum Neurotoxin-Producing Clostridia

Stewart Cole

Background: Clostridium botulinum and related clostridia express extremely potent toxins known as botulinum neurotoxins (BoNTs) that cause severe, potentially lethal intoxications in humans. These BoNT-producing bacteria are categorized in seven major toxi ...

Structure and function of the transketolase from Mycobacterium tuberculosis and comparison with the human enzyme

Stewart Cole, Florence Pojer, Elizabeth Fullam

The transketolase (TKT) enzyme in Mycobacterium tuberculosis represents a novel drug target for tuberculosis treatment and has low homology with the orthologous human enzyme. Here, we report on the structural and kinetic characterization of the transketola ...

Virulence Regulator EspR of Mycobacterium tuberculosis Is a Nucleoid-Associated Protein

Benjamin Blasco, Stewart Cole, Claudia Sala, Florence Pojer, Jeffrey Chen, Swapna Uplekar, Jacques Rougemont, Ruben Hartkoorn

The principal virulence determinant of Mycobacterium tuberculosis (Mtb), the ESX-1 protein secretion system, is positively controlled at the transcriptional level by EspR. Depletion of EspR reportedly affects a small number of genes, both positively or neg ...
