Structure-based drug design

Definition

Structure-based drug design is a method used in pharmaceutical development that relies on the three-dimensional structures of biological molecules, particularly proteins, to identify and create new drugs. This approach involves analyzing the binding sites of target proteins and designing molecules that can interact optimally with these sites, thereby enhancing efficacy and reducing side effects. By utilizing structural information, researchers can predict how small molecules will interact with proteins, allowing for more targeted and efficient drug development.
