Multidrug-resistant (MDR) infections demand new treatments. Host-acting antibacterial compounds (HACs) offer a promising strategy by targeting intracellular bacteria, providing novel therapeutic avenues.
Area of Science:
- Microbiology
- Infectious Diseases
- Pharmacology
Background:
- Rising prevalence of multidrug-resistant (MDR) bacterial infections poses a significant global health challenge.
- Traditional antibiotics are increasingly ineffective against MDR pathogens, necessitating novel therapeutic strategies.
- Host-acting antibacterial compounds (HACs) represent an emerging approach to combat intracellular bacterial infections.
Purpose of the Study:
- To review the interactions between host cells and facultative intracellular bacteria.
- To identify potential targets for the discovery and development of HACs.
- To summarize the mechanisms and activities of recently developed HACs against bacterial infections.
Main Methods:
- Literature review focusing on host-pathogen interactions.
- Analysis of existing data on HACs, their targets, and modes of action.
- Synthesis of information on pharmacological activities of HACs.
Main Results:
- HACs demonstrate potential in reducing or eliminating internalized bacteria.
- Specific host-bacterial interactions offer targets for HAC development.
- Various HACs exhibit diverse mechanisms against pathogenic bacteria.
Conclusions:
- HACs provide a promising alternative strategy for treating infections caused by cytosolic bacteria.
- This review highlights pathways for developing novel antibacterial agents targeting intracellular pathogens.
- Further research into HACs is crucial for addressing the threat of MDR infections.
