Topical anti-inflammatory activity of boropinic acid and its natural and semi-synthetic derivatives
摘要:
Boropinic acid is a natural isopentenyloxycinnamic acid extracted from the aerial parts of Boronia pinnata Sm. (Rutaceae) with soybean 5-lipoxygenase inhibitory activity. In this paper the topical anti-inflammatory activity of boropinic acid and some of its natural and semi-synthetic derivatives was evaluated using the Croton oil ear test in mice as a model of acute inflammation. Some of the tested compounds (15, 17, 19, 20) revealed an effect comparable (ID50 = 0.18 divided by 0.72 mu mol/cm(2)) to that of the reference drug indomethacin (ID50 = 0.23 mu mol/cm(2)), a non-steroidal anti-inflammatory drug.

Oxyprenylated naturally occurring cinnamic acids displayed efficient and promising biological activities. Aim of this study was to characterize the effects of 3-(4'-geranyl-3'-methoxy) phenyl-2-trans propenoic acid and its selected semi-synthetic analogues, on COX-2 expression and activity, and on COX-1 activity, in purified systems or in whole cell systems. The anti-inflammatory activity of title compounds (1) was tested as inhibition of COX-2 on isolated monocytes stimulated with LPS (10 mu g/ml). COX-2 expression was completely suppressed when monocytes were incubated with 100 mu M of 3-(4'-geranyl-3'-methoxy)phenyl-2-trans propenoic acid (1) or 3-(4'-isopentenyloxy) phenyl-2-trans propenoic acid (4). Moreover compounds (1) and (4) inhibit dose-dependently LPS-induced COX-2 expression. (c) 2011 Elsevier Ltd. All rights reserved.
