Small Molecule (API) Development

Small Molecule (API) Development

Small-Molecule-API-Development Pharmacology usually limits the term “small molecule” to a molecule that binds to a particular biological macromolecule and acts as an effector molecule, changing the activity or function of the target molecule. Small molecules have a variety of biological functions or applications, such as cell signaling molecules, drugs, agricultural pesticides and so on. These compounds can be natural (e.g. secondary metabolites) or artificial (e.g. antiviral drugs); they may be beneficial to diseases (e.g. drugs) or harmful (e.g. teratogens and carcinogens). Small molecules can be used as research tools to explore biological functions, as well as pioneers in the development of new therapeutic drugs.
