Structure-based virtual screening for the identification of RNA-binding ligands.

Area of Science:

• Computational chemistry
• Structural biology
• Drug discovery

Background:

• Structure-based virtual screening (SBVS) is crucial for identifying novel drug candidates.
• SBVS was initially developed for protein targets but has expanded to other biomolecules.
• RNA targets are increasingly recognized for their therapeutic potential.

Purpose of the Study:

• To provide an overview of SBVS for RNA targets.

• To offer guidance on avoiding common challenges in RNA virtual screening.

Main Methods:

• Exploiting the 3D structure of RNA targets as a template for ligand discovery.
• Utilizing computational software, freely available for noncommercial purposes, for virtual screening.
• Applying established SBVS principles to the unique characteristics of RNA.

Main Results:

• Demonstrated the applicability and utility of SBVS for RNA ligand discovery.
• Provided a comprehensive guide for researchers new to RNA virtual screening.
• Highlighted strategies to overcome common pitfalls in the process.

Conclusions:

• SBVS is an effective approach for discovering ligands that bind to RNA.
• The chapter equips researchers with the knowledge and tools for successful RNA-focused virtual screening.
• Emphasizes the importance of careful methodology to ensure reliable results in RNA drug discovery.
