Therapeutic Discovery

What Does "Target" Mean in Drug Discovery?

Identification of the appropriate target is a major part of drug discovery and development, as it is the starting point for drug design and optimization.


Target identification is an important step in drug discovery. It is the process of finding a specific molecule in the body that can serve as the target for a new drug. Through research, scientists identify molecules and pathways that are involved in disease processes, and then select one or more targets to pursue with further investigation. By targeting certain molecules, treatments can be designed to either inhibit or activate the biological function of those molecules, thus influencing disease progression and potentially providing a cure. It is important to select targets that are linked to the desired therapeutic effect and that have a high likelihood of success in drug development. The target for a drug must also be specific enough so that it only affects the intended cell or system in the body and not cause unintended effects. Identification of the appropriate target is a major part of drug discovery and development, as it is the starting point for drug design and optimization.
