Historically, new drugs have been discovered through the random screening of active ingredients from natural sources and then validation of the hits for activity in animal models. Target identification and Validation tells about the how target is neccesary for new drug discovery and its development to reach into market for rare diseases. The ability to perform in vivo target validation provides higher value information than in vitro validation to understand the role of a particular target in the disease process, multiple genes cooperation in the same pathway, as well as the role of the pathway in the disease. The identification and validation of disease-causing target genes is an essential first step in drug discovery and development. The process usually begins with extensive medical research about a particular disease, which provides researchers with a better understanding of the disease and how it affects the body. This approach is appealing because it holds the promise of identifying more efficacious compounds with fewer undesirable side effects. how it affects the body.

Another important method for drug discovery is de novo drug design, in which a prediction is made of the sorts of chemicals that might (e.g.) Otherwise, unless someone else has already blazed that trail, you’re going to be finding out not only “Is this compound going to hit the target”, but “Is this target worth hitting in the first place”. Today drug discovery involves screening hits, medicinal chemistry, and optimization of hits to reduce potential drug side effects (increasing affinity and selectivity). guide for making informed choices among the diverse target identification methods Target Discovery and Validation: Methods and Strategies for Drug Discovery offers a hands-on review of the modern technologies for drug target identification and validation. better understanding of the disease and Target identification in Antibody Drug Discovery is the process of identifying the molecular target of an Antibody - usually target cell surface molecules such as receptors or antigens expressed on tumor cells or other host cells.
