Ibuprofen was derived from propionic acid by the research arm of Boots Group during the 1960s. [73] The name is derived from the 3 functional groups: isobutyl (ibu) propionic acid (pro) phenyl (fen). [74] Its discovery was the result of research during the 1950s and 1960s to find a safer alternative to aspirin.
Drug nomenclature is the systematic naming of drugs, especially pharmaceutical drugs.In the majority of circumstances, drugs have 3 types of names: chemical names, the most important of which is the IUPAC name; generic or nonproprietary names, the most important of which are international nonproprietary names (INNs); and trade names, which are brand names.

Phenylephrine, sold under the brand names Neosynephrine and Sudafed PE among others, is a medication used as a decongestant for uncomplicated nasal congestion in the form of a nasal spray or oral tablet, [5] to dilate the pupil, to increase blood pressure given intravenously in cases of low blood pressure, and to relieve hemorrhoids as a suppository.
An International Nonproprietary Name (INN) is an official generic and nonproprietary name given to a pharmaceutical substance or an active ingredient, [1] encompassing compounds, peptides and low-molecular-weight proteins (e.g., insulin, hormones, cytokines), as well as complex biological products, such as those used for gene therapy. [2]
Ibuprofen, an analgesic and non-steroidal anti-inflammatory drug (NSAID), [1] is sold under many brand-names around the world. The most common are Brufen (its earliest registered trademark), Advil, Motrin, and Nurofen .
It is the active dextrorotatory enantiomer of ibuprofen. [1] Most ibuprofen formulations contain a racemic mixture of both isomers. Dexibuprofen is a chiral switch of racemic ibuprofen. The chiral carbon in dexibuprofen is assigned an absolute configuration of (S) per the Cahn–Ingold–Prelog rules. [2] [3] Dexibuprofen is also called (S ...
As a pharmacophore model should be able to discriminate between molecules with and without bioactivity, the set of molecules should include both active and inactive compounds. Conformational analysis – Generate a set of low energy conformations that is likely to contain the bioactive conformation for each of the selected molecules.
For example, cyclopropene is usually written C1=CC1, but if the double bond is chosen as the ring-closing bond, it may be written as C=1CC1, C1CC=1, or C=1CC=1. (The first form is preferred.) C=1CC-1 is illegal, as it explicitly specifies conflicting types for the ring-closing bond. Ring-closing bonds may not be used to denote multiple bonds.
