Computer-aided drug design (CADD) is a method that uses computer software to help scientists create new medications. By simulating how drugs interact with biological targets, researchers can predict which compounds might be effective. This approach speeds up the discovery process and reduces the need for extensive laboratory testing. CADD involves various techniques, including molecular modeling and structure-based drug design. These tools allow scientists to visualize the shapes and properties of molecules, helping them identify potential drug candidates. Overall, CADD plays a crucial role in modern pharmaceutical research, making drug development more efficient and targeted.
