Beyond the Discovery Void: New targets for antibacterial compounds.

Area of Science:

• Microbiology
• Pharmacology
• Infectious Diseases

Background:

• Antibiotics are crucial for treating bacterial infections, saving countless lives globally.
• The efficacy of existing antibiotics is severely threatened by the rise of antibiotic-resistant strains.
• Factors contributing to resistance include overprescription, population growth, and increased global travel.

Purpose of the Study:

• To highlight the critical threat posed by antibiotic resistance.
• To discuss the significant challenge of the antibiotic "discovery void"—the absence of new major antibiotic classes in 30 years.
• To review established antibiotic molecular targets and explore potential novel targets.

Main Methods:

• Literature review of traditional antibiotic targets.
• Exploration of emerging and putative novel molecular targets for antibiotic development.
• Analysis of factors driving antibiotic resistance and the discovery void.

Main Results:

• Identified key traditional molecular targets essential for antibiotic action.
• Highlighted several promising novel molecular targets for future drug development.
• Underscored the multifaceted reasons behind the current antibiotic discovery void.

Conclusions:

• Urgent need for novel antibiotic discovery and development to combat rising resistance.
• Exploring novel targets is critical to overcome the limitations of traditional approaches.
• Addressing the discovery void requires innovative strategies and research investment.
