AI Article Synopsis

  • Simplified versions of a bacterial-specific molecule called mycothiol were created to potentially deliver antimycobacterial drugs effectively.
  • Initial tests showed these mycothiol analogues had promising effects against model Mycobacteria, but more work is needed to enhance their targeting ability.

Article Abstract

Drug-resistant Mycobacterium tuberculosis is a growing health problem. As proof of principle that the bacterial-specific metabolite mycothiol could be used as a delivery agent for antimycobacterial agents, simplified analogues of mycothiol were synthesised containing an S-trichloroethenyl substituted cysteine residue. It was envisaged that uptake of the mycothiol analogue would be followed by release of the known cytotoxin S-trichloroethenyl cysteine by the action of mycothiol S-conjugate amidase or its paralog, mycothiol deacetylase MshB. Promising activity was displayed against model Mycobacteria, although further development will be required to improve selectivity.

Mycobacterial species in nature are found in abundance in sphagnum peat bogs where they compete for nutrients with a variety of microorganisms including fungi. We screened a collection of fungi isolated from sphagnum bogs by co-culture with Mycobacterium tuberculosis (Mtb) to look for inducible expression of antitubercular agents and identified 5 fungi that produced cidal antitubercular agents upon exposure to live Mtb. Whole genome sequencing of these fungi followed by fungal RNAseq after Mtb exposure allowed us to identify biosynthetic gene clusters induced by co-culture.

's () autarkic lifestyle within the host involves rewiring its transcriptional networks to combat host-induced stresses. With the help of RNA sequencing performed under various stress conditions, we identified that genes belonging to sulfur metabolism pathways are significantly upregulated during oxidative stress. Using an integrated approach of microbial genetics, transcriptomics, metabolomics, animal experiments, chemical inhibition, and rescue studies, we investigated the biological role of non-canonical L-cysteine synthases, CysM and CysK2.

Iron scavenging is required for full virulence of mycobacterial pathogens. During infection, the host immune response restricts mycobacterial access to iron, which is essential for bacterial respiration and DNA synthesis. The iron-dependent regulator (IdeR) responds to changes in iron accessibility by repressing iron-uptake genes when iron is available.

Unlabelled: (), the pathogenic bacterium that causes tuberculosis, has evolved sophisticated defense mechanisms to counteract the cytotoxicity of reactive oxygen species (ROS) generated within host macrophages during infection. The gene in and () plays a crucial role in defense mechanisms against ROS generated during infection. We demonstrate that encodes an epoxide hydrolase and contributes to ROS detoxification.
