A designer drug is a structural or functional analog of a controlled substance that has been designed to mimic the pharmacological effects of the original drug, while avoiding classification as illegal andor detection in standard drug tests. Classical bioisosterism was originally formulated by james moir and refined by irving langmuir as a response to the observation that different atoms with the same valence electron structure had similar biological properties for example, the replacement of a hydrogen atom with a fluorine atom at a site of metabolic oxidation in a drug candidate may prevent such metabolism from taking place. It is a survey of basic principles of drug design and drug action in which the concepts are presented from a physical organic chemistry perspective so that the design, development, and mechanisms of action and metabolism of drugs can be rationally understood. Isosterism can also contribute to the productive application in the design and optimization of catalysts on organic chemistry.
