Structure-based drug design

Definition

Structure-based drug design is a method used in pharmaceutical research to discover new medications by utilizing the three-dimensional structure of biological molecules, particularly proteins. This approach relies on understanding the molecular interactions between a target protein and potential drug candidates, allowing for the design of compounds that can specifically bind and alter the activity of the target. By employing techniques such as X-ray crystallography and computational modeling, researchers can optimize drug efficacy and reduce side effects.
