Synthesis and anti-inflammatory activity of 3-(4′-geranyloxy-3′-methoxyphenyl)-2-trans propenoic acid and its ester derivatives

Different esters of 3-(4′-geranyloxy-3′-methoxyphenyl)-2-trans propenoic acid (1), an anti-inflammatory principle of Acronychia baueri Schott (Rutaceae), were synthesized. Their topical anti-inflammatory activity was evaluated using the Croton oil ear test in mice as a model of acute inflammation. The activity of the paracetamol, guaiacol and hydroquinone esters of (1) was higher than that of the parent compound, being similar to that exerted by indomethacin, used as reference drug.

The synthesis of ester derivatives of the title acid and their anti-inflammatory activity are reported.Figure optionsDownload as PowerPoint slide
