Fluorescent Benzothiazinone Analogues Efficiently and Selectively Label Dpre1 in Mycobacteria and Actinobacteria

Paul Joseph Dyson, Stewart Cole, John McKinney, Neeraj Dhar, Thierry Laroche, Jérémie Piton, Joao Pedro De Almeida Neres, Raphael Christopher Sommer, Raju Mukherjee

Benzothiazinones (BTZ) are highly potent bactericidal inhibitors of mycobacteria and the lead compound, BTZ043, and the optimized drug candidate, PBTZ169, have potential for the treatment of tuberculosis. Here, we exploited the tractability of the BTZ scaf ...

Nitroarenes as Antitubercular Agents: Stereoelectronic Modulation to Mitigate Mutagenicity

Joao Pedro De Almeida Neres

Nitroarenes are less preferred in drug discovery due to their potential to be mutagenic. However, several nitroarenes were shown to be promising antitubercular agents with specific modes of action, namely, nitroimidazoles and benzothiazinones. The nitro gr ...

Characterization of DprE1-Mediated Benzothiazinone Resistance in Mycobacterium tuberculosis

Stewart Cole, Claudia Sala, Stefanie Boy-Röttger, Joao Pedro De Almeida Neres, Benoit Lechartier, Jérémie Piton, Gaëlle Séraphine Kolly, Jan Lars Rybniker, Shi-Yan Caroline Foo, Andréanne Lupien

Benzothiazinones (BTZs) are a class of compounds found to be extremely potent against both drug-susceptible and drug-resistant Mycobacterium tuberculosis strains. The potency of BTZs is explained by their specificity for their target decaprenylphosphoryl-D ...

DprE1 Is a Vulnerable Tuberculosis Drug Target Due to Its Cell Wall Localization

Stewart Cole, Gaëlle Séraphine Kolly, Joao Pedro De Almeida Neres, Raju Mukherjee

The flavo-enzyme DprE1 catalyzes a key epimerization step in the decaprenyl-phosphoryl d-arabinose (DPA) pathway, which is essential for mycobacterial cell wall biogenesis and targeted by several new tuberculosis drug candidates. Here, using differential r ...

2-Carboxyquinoxalines Kill Mycobacterium tuberculosis through Noncovalent Inhibition of DprE1

Stewart Cole, Neeraj Dhar, Florence Pojer, Ruben Hartkoorn, Joao Pedro De Almeida Neres, Gaëlle Séraphine Kolly

Phenotypic screening of a quinoxaline library against replicating Mycobacterium tuberculosis led to the identification of lead compound Ty38c (3-((4-methoxybenzyl)amino)-6-(trifluoromethyl)quinoxaline-2-carboxylic acid). With an MIC99 and MBC of 3.1 mu M, ...

Discovery of benzothiazoles as antimycobacterial agents: Synthesis, structure-activity relationships and binding studies with Mycobacterium tuberculosis decaprenylphosphoryl-beta-D-ribose 2 '-oxidase

Stewart Cole, Florence Pojer, Joao Pedro De Almeida Neres, Anirban Ghosh

We report the discovery of benzothiazoles, a novel anti-mycobacterial series, identified from a whole cell based screening campaign. Benzothiazoles exert their bactericidal activity against Mycobacterium tuberculosis (Mtb) through potent inhibition of deca ...

The 8-Pyrrole-Benzothiazinones Are Noncovalent Inhibitors of DprE1 from Mycobacterium tuberculosis

Stewart Cole, Ruben Hartkoorn, Joao Pedro De Almeida Neres, Anthony Vocat, Trent Michael Conroy, Jérémie Piton, Gaëlle Séraphine Kolly

8-Nitro-benzothiazinones (BTZs), such as BTZ043 and PBTZ169, inhibit decaprenylphosphoryl-beta-D-ribose 2'-oxidase (DprE1) and display nanomolar bactericidal activity against Mycobacterium tuberculosis in vitro. Structure-activity relationship (SAR) studie ...

4-Aminoquinolone Piperidine Amides: Noncovalent Inhibitors of DprE1 with Long Residence Time and Potent Antimycobacterial Activity

John McKinney, Neeraj Dhar, Joao Pedro De Almeida Neres, François Signorino-Gelo

4-Aminoquinolone piperidine amides (AQs) were identified as a novel scaffold starting from a whole cell screen, with potent cidality on Mycobacterium tuberculosis (Mtb). Evaluation of the minimum inhibitory concentrations, followed by whole genome sequenci ...

Selective detection of epimeric pentose saccharides at physiological pH using a fluorescent receptor

Matthew Gibson, Joao Pedro De Almeida Neres, Elizabeth Fullam

Epimerisation between ribofuranose and arabinofuranose sugars is crucial in several biosynthetic pathways, but is typically challenging to monitor. Here, we have screened for fluorescent boronic acids that can be used as molecular probes for the specific d ...

Pyridomycin bridges the NADH- and substratebinding pockets of the enoyl reductase InhA

Stewart Cole, Florence Pojer, Ruben Hartkoorn, Joao Pedro De Almeida Neres

Pyridomycin, a natural product with potent antituberculosis activity, inhibits a major drug target, the InhA enoyl reductase. Here, we unveil the co-crystal structure and unique ability of pyridomycin to block both the NADH cofactor- and lipid substrate-bi ...
