In chemistry and pharmacology, functional analogs are chemical compounds that have similar physical, chemical, biochemical, or pharmacological properties. Functional analogs are not necessarily structural analogs with a similar chemical structure. [1]
A structural analog, also known as a chemical analog or simply an analog, is a compound having a structure similar to that of another compound, but differing from it in respect to a certain component. [1] [2] [3] It can differ in one or more atoms, functional groups, or substructures, which are replaced with other atoms, groups, or ...
In the United States, the Controlled Substances Act was amended by the Controlled Substance Analogue Enforcement of 1986, which attempted to ban designer drugs pre-emptively by making it illegal to manufacture, sell, or possess chemicals that were substantially similar in chemistry and pharmacology to Schedule I or Schedule II drugs.
The antiviral drug aciclovir (bottom), a nucleoside analogue that functions by mimicking guanosine (top) Nucleoside analogues are structural analogues of a nucleoside, which normally contain a nucleobase and a sugar. Nucleotide analogues are analogues of a nucleotide, which normally has one to three phosphates linked to a nucleoside.
Prostaglandin analogues such as misoprostol are used in treatment of duodenal and gastric ulcers. [2] Misoprostol and other prostaglandin analogues protect the lining of the gastrointestinal tract from harmful stomach acid and are especially indicated for the elderly on continuous doses of NSAIDs.
To design a transition state analogue, the pivotal step is the determination of transition state structure of substrate on the specific enzyme of interest with experimental method, for example, kinetic isotope effect. In addition, the transition state structure can also be predicted with computational approaches as a complementary to KIE.
3D molecular rendering of methylphenidate (MPH). This is a list of methylphenidate (MPH or MPD) analogues, or Phenidates.The most well known compound from this family, methylphenidate, is widely prescribed around the world for the treatment of attention deficit hyperactivity disorder (ADHD) and certain other indications.
An insulin analog (also called an insulin analogue) is any of several types of medical insulin that are altered forms of the hormone insulin, different from any occurring in nature, but still available to the human body for performing the same action as human insulin in terms of controlling blood glucose levels in diabetes.
