Hazard Information

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

4-Biphenylacetic acid was used in the synthesis of gastrosparing non-steroidal antiinflammatory drug.

Uses

Anti-inflammatory, analgesic 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.

storage

Store at -20°C
