Design and Synthesis of Pyrano[3,2-b]indolones Showing Antimycobacterial Activity

Stewart Cole, Anthony Vocat

Latent Mycobacterium tuberculosis infection presents one of the largest challenges for tuberculosis control and novel antimycobacterial drug development. A series of pyrano[3,2-b]indolone-based compounds was designed and synthesized via an original eight-s ...

Leprosy in wild chimpanzees

Stewart Cole, Charlotte Avanzi, Philippe Busso

Humans are considered as the main host for Mycobacterium leprae(1), the aetiological agent of leprosy, but spillover has occurred to other mammals that are now maintenance hosts, such as nine-banded armadillos and red squirrels(2,3). Although naturally acq ...

Mycobacterium leprae diversity and population dynamics in medieval Europe from novel ancient genomes

Stewart Cole, Charlotte Avanzi, Philippe Busso

Background Hansen's disease (leprosy), widespread in medieval Europe, is today mainly prevalent in tropical and subtropical regions with around 200,000 new cases reported annually. Despite its long history and appearance in historical records, its origins ...

Structural and DNA binding properties of mycobacterial integration host factor mIHF

Stewart Cole, David Lyndon Emsley, Giovanni Dietler, Luciano Andres Abriata, Jérémie Piton, Aleksandre Japaridze, Moreno Lelli, Nina Theres Odermatt, Rajkumar Singh

In bacteria, nucleoid associated proteins (NAPs) take part in active chromosome organization by supercoil management, three-dimensional DNA looping and direct transcriptional control. Mycobacterial integration host factor (mIHF, rv1388) is a NAP restricted ...

Emergence of Mycobacterium leprae Rifampin Resistance Evaluated by Whole-Genome Sequencing after 48 Years of Irregular Treatment

Stewart Cole, Andrej Benjak, Charlotte Avanzi, Philippe Busso

A case of Mycobacterium leprae rifampin resistance after irregular antile- prosy treatments since 1971 is reported. Whole-genome sequencing from four longi- tudinal samples indicated relapse due to acquired rifampin resistance and not to re- infection with ...

Advanced Quantification Methods To Improve the 18b Dormancy Model for Assessing the Activity of Tuberculosis Drugs In Vitro

Stewart Cole, Claudia Sala

One of the reasons for the lengthy tuberculosis (TB) treatment is the difficulty to treat the nonmultiplying mycobacterial subpopulation. In order to assess the ability of (new) TB drugs to target this subpopulation, we need to incorporate dormancy models ...

6,11-Dioxobenzo[f]pyrido[1,2-a]indoles Kill Mycobacterium tuberculosis by Targeting Iron-Sulfur Protein Rv0338c (IspQ), A Putative Redox Sensor

Stewart Cole, Kai Johnsson, Andrej Benjak, Jérémie Piton, Edina Rita Székely, Monica Rengifo Gonzalez

Screening of a diversity-oriented compound library led to the identification of two 6,11-dioxobenzo[f]pyrido[1,2-a]indoles (DBPI) that displayed low micromolar bactericidal activity against the Erdman strain of Mycobacterium tuberculosis in vitro. The acti ...

Synthesis and Structure-Activity Relationship Studies of C2-Modified Analogs of the Antimycobacterial Natural Product Pyridomycin

Stewart Cole, Ruben Hartkoorn, Anthony Vocat

A series of derivatives of the antimycobacterial natural product pyridomycin have been prepared with the C2 side chain attached to the macrocyclic core structure by a C-C single bond, in place of the synthetically more demanding enol ester double bond foun ...

High resolution CryoEM structure of the ring-shaped virulence factor EspB from Mycobacterium tuberculosis

Stewart Cole, Florence Pojer, Jérémie Piton

The EspB protein of Mycobacterium tuberculosis is a 60 kDa virulence factor, implicated in conjugation and exported by the ESX-1 system of which it may also be a component. Previous attempts to obtain high-resolution maps of EspB by cryo-electron microscop ...

FasR Regulates Fatty Acid Biosynthesis and Is Essential for Virulence of Mycobacterium tuberculosis

Stewart Cole, Claudia Sala

Mycobacterium tuberculosis, the etiologic agent of human tuberculosis, is the world's leading cause of death from an infectious disease. One of the main features of this pathogen is the complex and dynamic lipid composition of the cell envelope, which adap ...
