Novel arylpropionic derivatives with analgesic action and the process for the preparation thereof

摘要

The present invention relates to novel arylpropionic derivatives, namely the salts of (+)-(s)-2-(3-benzoylphenyl)propionic acid with metal ions of formula (I), wherein M<+> is the required stoichiometric amount of the cations corresponding to sodium, potassium, calcium, magnesium, zinc or aluminium. The process for the preparation thereof comprises reacting (+)-(S)-2-(3-benzoylphenyl)propionic acid (II) or a salt thereof with a metal hydroxide or salt. Said compounds exhibit high analgesic and anti-inflammatory actions in human therapy.
