WebJul 23, 2024 · While target-based drug discovery (TDD) determines how a specific compound interacts with a target, phenotypic screening compares several compounds to find the one that results in the desired phenotype. Phenotypic screens are cell-based such as proliferation assays to determine how a drug affects cell growth. WebMar 18, 2024 · Phenotypic drug discovery (PDD), using biological systems directly to discover effective drugs, has been promoted in recent years as an alternative to TDD.
