Drug design is the process of creating new medications based on the knowledge of biological targets. Scientists study the structure and function of proteins or enzymes involved in diseases to identify potential targets for new drugs. By understanding how these targets work, researchers can design molecules that interact with them effectively. The goal of drug design is to develop compounds that are both effective and safe for patients. This involves using techniques like computer-aided drug design and high-throughput screening to test various compounds. Successful drug design can lead to new treatments for various conditions, improving patient outcomes and quality of life.
