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 ...
Northwestern University's High Throughput Analysis Laboratory supports target identification, validation, assay development, and compound screening. The non-profit Sanford Burnham Prebys Medical Discovery Institute also has a long-standing HTS facility in the Conrad Prebys Center for Chemical Genomics which was part of the MLPCN.
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.
Computational Resources for Drug Discovery (CRDD) is an important module of the in silico module of Open Source for Drug Discovery (OSDD). [1] The CRDD web portal provides computer resources related to drug discovery, predicting inhibitors, and predicting the ADME-Tox properties of molecules on a single platform.
Target validation (TV) → Assay development → High-throughput screening (HTS) → Hit to lead (H2L) → Lead optimization (LO) → Preclinical development → Clinical development The hit to lead stage starts with confirmation and evaluation of the initial screening hits and is followed by synthesis of analogs (hit expansion).

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:
