Structurebased design is a method for drug discovery and development that relies on the three-dimensional structure of a biological target molecule, such as a protein or nucleic acid, to guide the design of therapeutic agents. This approach, also known as rational drug design, contrasts with traditional methods that might involve random screening of large compound libraries.

The core principle of structurebased design is that understanding the shape and chemical properties of a target's active site or binding pocket allows researchers to design molecules that can interact with it specifically and effectively. This involves determining the structure of the target, often through experimental techniques like X-ray crystallography or Nuclear Magnetic Resonance (NMR) spectroscopy, or through computational modeling. Once the structure is known, computational tools can be used to visualize the binding site, identify key amino acid residues or chemical features, and predict how potential drug molecules might bind.

In practice, structurebased design often involves docking studies where candidate molecules are computationally fitted into the target's binding site. This helps to predict binding affinity and pose. Lead compounds identified through this process are then synthesized and tested experimentally. The structural information is continuously refined as new experimental data becomes available or as modifications are made to the drug candidate, leading to an iterative process of optimization. This approach can significantly accelerate the drug discovery timeline and increase the likelihood of success by focusing resources on molecules with a higher probability of efficacy and specificity.
