| | 4-Biphenylacetic acid Usage And Synthesis |
| Description | Felbinac Is the active metabolite of the non-steroidal antiinflammatory agent,
fenbufen. Applied topically as a gel to joints, it is useful in the symptomatic relief
of articular inflammation and pain. | | Chemical Properties | Off-white powder | | Originator | Lederle (USA) | | Uses | Anti-inflammatory, analgesic drug. | | Uses | 4-Biphenylacetic acid was used in the synthesis of gastrosparing non-steroidal antiinflammatory drug. | | Definition | ChEBI: Biphenyl-4-ylacetic acid is a monocarboxylic acid in which one of the alpha-hydrogens is substituted by a biphenyl-4-yl group. An active metabolite of fenbufen, it is used as a topical medicine to treat muscle inflammation and arthritis. It has a role as a non-steroidal anti-inflammatory drug. It is a member of biphenyls and a monocarboxylic acid. It contains a biphenyl-4-yl group. It is functionally related to an acetic acid. | | Brand name | Dolinac (Wyeth-Ayerst); Flexfree(Wyeth-Ayerst); Napageln (Wyeth-Ayerst); Target
(Wyeth-Ayerst); Traxam (Wyeth-Ayerst). | | General Description | 4-Biphenylacetic acid is a potential non-steroidal antiinflammatory agent and forms solid inclusion complex with β-cyclodextrin. 4-Biphenylacetic acid on interaction with quinolone antibacterial agents induces functional blockade of the γ-aminobutyric acid receptors. | | Safety Profile | Poison by subcutaneous route.Moderately toxic by ingestion and intraperitoneal routes.An experimental teratogen. Other experimentalreproductive effects. When heated to decomposition itemits acrid smoke and fumes. | | Synthesis |
First 4-aminophenylacetic acid is prepared by reducing 4-nitrophenylacetic acid in the presence of a palladium-carbon catalyst; 4-Biphenylacetic acid is finally prepared by reacting 4-aminophenylacetic acid with benzene in the presence of sodium nitrite and an acid.
