Structure-based drug design

Definition

Structure-based drug design is a method used in drug discovery that relies on the three-dimensional structure of biological molecules to identify and develop new medications. This approach involves analyzing the structure of target proteins to understand how potential drug compounds can interact with them, leading to optimized therapeutic agents. It connects molecular biology with computational techniques, which include homology modeling and drug repurposing strategies.
