Fenbufen

Fenbufen is a non-steroidal anti-inflammatory drug (NSAID) and a prodrug form of 4-biphenylacetic acid. Fenbufen (125 µg/ml) inhibits collagen-induced, but not arachidonate-induced, platelet aggregation in vitro. In vivo, fenbufen (8-250 mg/kg) suppresses UV-induced erythema in guinea pigs. It reduces phenylquinone-induced writhing in mice (ED50 = 7.7 mg/kg) and brewer's yeast-induced mechano-allodynia in rats (ED50 = 29 mg/kg). Fenbufen (28 mg/kg) reduces inflammation in a rat model of adjuvant-induced arthritis. It also reduces yeast-induced fever in rats. Formulations containing fenbufen were previously used in the treatment of osteoarthritis and inflammatory pain.Formal Name: gamma-oxo-[1,1'-biphenyl]-4-butanoic acid. CAS Number: 36330-85-5.
