Phenotypic screening : ウィキペディア英語版 | Phenotypic screening Phenotypic screening is a type of screening used in biological research and drug discovery to identify substances such as small molecules, peptides, or RNAi that alter the phenotype of a cell or an organism in a desired manner. == Historical context ==
Phenotypic screening historically has been the basis for the discovery of new drugs. Compounds are screened in cellular or animal disease models to identify compounds that cause a desirable change in phenotype. Only after the compounds have been discovered, an effort is made to determine the biological target of the compounds. This strategy is known as "classical pharmacology", "forward pharmacology" or "phenotypic drug discovery" (PDD). More recently it has become popular to develop a hypothesis that a certain biological target is disease modifying, and then screen for compounds that modulate the activity of this purified target. Afterwards, these compounds are tested in animals to see if they have the desired effect. This approach is known as "reverse pharmacology" or "target based drug discovery" (TDD). However recent statistical analysis reveals that a disproportionate number of first-in-class drugs with novel mechanisms of action come from phenotypic screening which has led to a resurgence of interest in this method.〔
