Synthesis, platelet anti-aggregating activity and anti-inflammatory activity of a series of beta-aminoxypropionic acids.

This paper reports the platelet anti-aggregating activity induced by arachidonic acid (AA) and by adenosine-diphosphate (ADP), together with the anti-inflammatory activity evaluated by the carrageenan-induced rat paw edema method, of a series of beta-aminoxypropionic acids which were projected and synthesised as analogues of non-steroidal anti-inflammatory drugs with an arylacetic structure B, in which the aromatic group is substituted by a methyleneaminoxymethylic moiety. Some of the beta-aminoxypropionic acids were evaluated for their capacity to inhibit the cyclooxygenase enzyme by measuring the malondialdehyde (MDA) produced by incubation of sodium arachidonate with platelet-rich plasma (PRP).
