Drug Repositioning: A Unique Approach to Refurbish Drug Discovery

Area of Science:

• Pharmacology
• Medicinal Chemistry
• Drug Discovery

Background:

• A notable decline in novel clinically approved drugs has persisted for a decade.
• Modernization in research and development has not fully overcome this challenge.
• Drug repositioning emerges as a vital strategy to address this drug development gap.

Purpose of the Study:

• To review the methodology and significance of drug repositioning.
• To explore an activity-based drug repositioning approach.
• To highlight current research trends and computational tools in drug repositioning.

Main Methods:

• Focus on an activity-based drug repositioning strategy.
• Leveraging knowledge of medicinal chemistry for target elucidation.
• Utilizing computational tools and databases for hypothesis generation.

Main Results:

• Drug repositioning identifies new therapeutic indications for existing drugs.
• This approach capitalizes on drugs interacting with multiple targets.
• Computational tools enhance the ability to formulate testable hypotheses.

Conclusions:

• Drug repositioning provides timely and cost-effective solutions for drug development.
• It is a promising strategy to overcome the shortage of novel drugs.
• This approach can evolve into a robust drug discovery framework.
