  • The rise of antibiotic-resistant bacterial infections is a serious public health issue, highlighting the need for new antibacterial drug targets.
  • MraY, a crucial protein for bacterial cell wall synthesis, has emerged as a promising target for drug development.
  • Recent research on MraY and its related human protein, GPT, has revealed how they interact with natural inhibitors, which could inform the design of effective new antibacterial agents.

Article Abstract

The rapid growth of antibiotic-resistant bacterial infections is of major concern for human health. Therefore, it is of great importance to characterize novel targets for the development of antibacterial drugs. One promising protein target is MraY (UDP-N-acetylmuramyl-pentapeptide: undecaprenyl phosphate N-acetylmuramyl-pentapeptide-1-phosphate transferase or MurNAc-1-P-transferase), which is essential for bacterial cell wall synthesis. Here, we summarize recent breakthroughs in structural studies of bacterial MraYs and the closely related human GPT (UDP-N-acetylglucosamine: dolichyl phosphate N-acetylglucosamine-1-phosphate transferase or GlcNAc-1-P-transferase). We present a detailed comparison of interaction modes with the natural product inhibitors tunicamycin and muraymycin D2. Finally, we speculate on possible routes to design an antibacterial agent in the form of a potent and selective inhibitor against MraY.

Article Synopsis
  • MraY inhibitory natural products are promising candidates for new antibacterial treatments, especially against drug-resistant bacteria, but improving their properties through chemical modifications is challenging due to complex synthesis processes.
  • A new strategy has been developed to efficiently create and evaluate a library of 686 MraY analogue compounds, allowing for streamlined preparation and direct assessment of their biological activities.
  • This research identifies several potent analogues that are effective against drug-resistant strains and reveals unique binding patterns with MraY, while also demonstrating the method's applicability to other natural products targeting tubulin activities.

Chlamydial infections and diseases caused by filarial nematodes are global health concerns. However, treatment presents challenges due to treatment failures potentially caused by persisting and long regimens against filarial infections accompanied by low compliance. A new treatment strategy could be the targeting of the reduced peptidoglycan structures involved in cell division in the obligate intracellular bacteria and , the latter being obligate endosymbionts supporting filarial development, growth, and survival.

Article Synopsis
  • - The study focused on the antimicrobial resistance (AMR) rates in swine and human pathogens from Spain between 2016 and 2021, finding over 80% resistance to several antibiotic classes and 90% of isolates displayed multidrug resistance.
  • - A total of 116 isolates were analyzed for their antibiotic susceptibility and genetic backgrounds, revealing significant correlations between AMR and factors such as the sequence types, geographic regions, and age of pigs.
  • - Whole genome sequencing identified 23 AMR genes, including 4 novel ones, with many located on mobile genetic elements, highlighting the complex origins of resistance and suggesting implications for both animal and human health.
