    Abstract:
    The activity of N-2-(p-chlorophenoxy)-isobutyryl-N'-morpholinomethylurea (plafibride, ITA 104) on arachidonic acid metabolism, the 3',5'-cyclic AMP-phosphodiesterase and the serum clearance of a lipid emulsion is reported in order to clarify its mechanism of action on platelet aggregation and lipid metabolism. Plafibride did not act on the arachidonic acid metabolism as far as platelet aggregation was concerned, since it did not modify the generation of prostaglandin endoperoxides nor prostacyclin. Neither did it act on the generation of thromboxane A2. Plafibride inhibited the activity of 3',5'-cyclic AMP-phosphodiesterase, which is one of the principal mechanisms of inhibition of platelet aggregation. The serum c clearance of a commercial lipid emfy the generation of prostaglandin endoperoxides nor prostacyclin. Neither did it act on the generation of thromboxane A2. Plafibride inhibited the activity of 3',5'-cyclic AMP-phosphodiesterase, which is one of the principal mechanisms of inhibition of platelet aggregation. The serum clearance of a commercial lipid emulsion was increased by plafibride which also possessed a strong hypotriglyceride activity. The correlation between platelet antiaggregant and hypolipemic activity of plafibride is discussed in this paper.
