Drug target validation is the process of determining if a specific molecular target, such as a protein or receptor, is a viable candidate for the development of new therapeutic drugs. This process involves a series of experiments and studies to confirm that the target plays a key role in the disease or condition being targeted, and that modulating its activity with a drug could lead to a beneficial therapeutic effect. Drug target validation is an essential step in drug discovery and development, as it helps to ensure that resources are focused on promising targets that have a high likelihood of success in clinical trials.
