title: Oxime ether derivatives, a new class of nonsteroidal antiinflammatory compounds.
abstract: A series of new 2-hydroxyethyl and carboxyalkyl ethers of aromatic oximes was found to possess pronounced antiinflammatory activity in the carrageenan-induced edema test in the rat. The activity was limited mainly to derivatives of p-haloacetophenone oxime and of p-halobenzaldehyde oxime. Nevertheless, the hydroxyethyl and carboxyalkyl groups may be converted into many derivatives with maintenance of activity. Some structure-activity relationships are in contrast to those of the well-known antiinflammatory arylacetic acids. The activity is limited to the E stereoisomers. The hydrochloride of 2-(dimethylamino)ethyl (E)-[[(p-chloro-alpha-methylbenzylidene)-amino[oxy]acetate (36, INN name Cloximate) was chosen for clinical evaluation. The first results agree with the pharmacological prospects.
