An intrarenal infusion of such an inhibitor, YS-980 (thiazolidine carboxylic acid derivative), at a rate of 0.1 mg/min resulted in a significant fall in systemic arterial blood pressure and a significant increase in renal blood flow, urine flow, urinary excretion of sodium and renin release in anesthetized dogs. These renal effects evoked by YS-980 were abolished after the inhibition of kallikrein as induced by aprotinin (900 kallikrein inhibitory units per min). In addition, YS-980 given after the administration of indomethacin (5 mg/kg i.v.) had no effect on the renal hemodynamics and renin release except for the urinary excretion of sodium. These findings suggest that both the kallikrein-kinin system and prostaglandins contribute to the renal action and the vasodepressor effect of YS-980. It would appear that the intrarenal administration of this angiotensin converting enzyme inhibitor induced marked renal effects through activation of kinin and prostaglandins and that the relative contribution of the renin-angiotensin system is negligible in anesthetized dogs.}, issn = {0022-3565}, URL = {https://jpet.aspetjournals.org/content/214/1/166}, eprint = {https://jpet.aspetjournals.org/content/214/1/166.full.pdf}, journal = {Journal of Pharmacology and Experimental Therapeutics} }
