Nonsteroidal antiinflammatory agents. Part 16: Stereomeric 3-aryl-biphenylyl-hydroxy-propionic acids.

As part of a wider research project on structure-activity relationships of chiral arylalkanoic acids, stereomeric aryl- biphenylyl-hydroxypropionic acids 3a-d have been prepared and their antiinflammatory activity evaluated. Diastereomeric racemic erythro- and threo-acids have been synthesized by reaction of alpha-lithiated biphenylyl-acetic acid salts with the appropriate aldehyde. They were separated, and after attribution of their relative configuration by 1H-NMR analysis, resolved. The antiinflammatory activities of the enantiomeric potassium salts were determined by the carrageenan test.

[Nonsteroidal anti-inflammatory agents. XIII. 4-Cyclohexylphenylhydroxyalkanoic acids].

The preparation of some homologues of 2-(4-cyclohexylphenyl)-3-hydroxypropionic acid, the separation of the diastereomeric race-mates, their attribution to erythro and threo series, and the optical resolution of the enantiomers are described. The optical antipodes were screened for acute toxicity, as well as for antiinflammatory and analgesic activity.

[Non-steroidal anti-inflammatory agents. Stereoisomers of homologues of 2-(4-biphenylyl)-3-hydroxypropionic acid. XII].

The synthesis of some homologues of 2-(4-biphenylyl)-3-hydroxypropionic acid, the separation of related diastereoisomers, their attribution to erythro and threo series, and resolution of the optical antipodes are described. The antiinflammatory activity--initially tested by carrageenin assay--proves generally influenced by steric configuration and is interesting for the isohexanoic derivative.
