Target validation normally requires the determination that the target is expressed in the disease-relevant cells/tissues, [6] it can be directly modulated by a drug or drug-like molecule with adequate potency in biochemical assay, [7] and that target modulation in cell and/or animal models ameliorates the relevant disease phenotype. [8]
The process of finding a new drug against a chosen target for a particular disease usually involves high-throughput screening (HTS), wherein large libraries of chemicals are tested for their ability to modify the target. For example, if the target is a novel GPCR, compounds will be screened for their ability to inhibit or stimulate that ...
Validation is a requirement of food, drug and pharmaceutical regulating agencies such as the US FDA and their good manufacturing practices guidelines. Since a wide variety of procedures, processes, and activities need to be validated, the field of validation is divided into a number of subsections including the following: Equipment validation
This approach is known as "reverse pharmacology" or "target based drug discovery" (TDD). [5] However recent statistical analysis reveals that a disproportionate number of first-in-class drugs with novel mechanisms of action come from phenotypic screening [ 6 ] which has led to a resurgence of interest in this method.
Druggability is a term used in drug discovery to describe a biological target (such as a protein) that is known to or is predicted to bind with high affinity to a drug. Furthermore, by definition, the binding of the drug to a druggable target must alter the function of the target with a therapeutic benefit to the patient.
ISPE has published a series of good practice guides for the industry on several topics involved in drug manufacturing. The most well-known is The Good Automated Manufacturing Practice (GAMP) Guide for Validation of Automated Systems in Pharmaceutical Manufacture. The second edition (GAMP5) was released in July 2022.

This version contained 1424 approved small molecule drugs and 132 biotech drugs as well as >4000 unique drug targets. Version 3.0 also included drug transporter data, drug pathway data, drug pricing, patent and manufacturing data as well as data on >5000 experimental drugs.
target is the antigen at which the antibody is directed. This parameter takes free text as value, preferably including a wikilink such as |target=[[TNF-α]]. The drug name is followed by a "?" linked to Nomenclature of monoclonal antibodies, saving the need to explain how each monoclonal antibody has been named. Shortened Monoclonal antibody form:
