- Virtual screening methods are essential for large-scale compound analysis.
- Pharmacophore modeling provides a 3D representation of molecular interactions.
Purpose of the Study:
- To develop a fast, large-scale in silico system for virtual activity profiling.
- To validate the efficacy of parallel pharmacophore-based virtual screening.
- To assess the prediction accuracy of biological targets for antiviral compounds.
Main Methods:
- Utilized LigandScout and Catalyst software for in silico screening.
- Employed 50 structure-based pharmacophore models for viral targets.
- Screened 100 antiviral compounds against all developed pharmacophore models.
Main Results:

Drug Discovery: Overview
Drug discovery is a multifaceted process involving extensive screening, testing, and optimization of lead compounds to identify potential new drugs for therapeutic use. It combines several approaches, including screening large numbers of natural products, chemical modification of known active molecules, identification of new drug targets, and rational design based on biological mechanisms and drug-receptor structure. These approaches are carried out in both academic research laboratories and...
Structure-Activity Relationships and Drug Design
Drug design is a dynamic field that involves discovering and developing new medications based on specific biological targets. This process heavily relies on structure-activity relationships (SAR) and quantitative structure-activity relationships (QSAR) to guide the design and optimization of efficient drugs.
SAR studies the intricate relationship between a drug's chemical structure and biological activity. It focuses on understanding how modifications to a drug's structure can influence its...

Genetic Screens
Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which result in visible changes...
