Biochem/physiol Actions

DAA-I (des-aspartate-angiotensin-I) is an agonist on the angiotensin AT1 receptor and releases prostaglandins which mediate its actions. DAA-I administer at doses lesser than Km of metabolizing enzymes antagonize the deleterious actions of angiotensin II. DAA-I appear function in vivo as a physiological antagonist to angiotensin II.
Des-aspartate-angiotensin I (DAA-I) is a nine-amino acid angiotensin peptide and a metabolite of angiotensin DAA-I mediates attenuation of early inflammatory processes and intercellular adhesion molecule-1 (ICAM-1) formation in animal models.

Although clinical studies suggested that blockade of the renin-angiotensin system may prevent diabetes, the mechanism is uncertain. As a follow-up to an earlier study, we investigated how des-aspartate-angiotensin-1 (DAA-1) and its metabolite, angiotensin IV (Ang-IV) improved glucose tolerance in diet-induced

We investigate the influence of des-Aspartate-angiotensin-I (DAA-I) on the cytokine expression profile in a rodent model of myocardial infarction. Myocardial infarction model was created in female Wistar rats by coronary artery ligation. Animals were randomized to receive intravenously either a

The present study investigated the actions of des-aspartate-angiotensin I (DAA-I) on infarct size and three early inflammatory events in acute myocardial ischemia-reperfusion injury in rats. The rationale was based on earlier findings showing that chronic daily administration of DAA-I attenuated

The review describes DAA-I (des-aspartate-angiotensin-I) as a prototype of a novel class of drugs that acts as agonists on the angiotensin AT1 receptor or ARAs (angiotensin receptor agonists). DAA-I is a component of the renin angiotensin system. Earlier studies showed

The present study investigated the action of des-aspartate-angiotensin I (DAA-I) on the pressor action of angiotensin II in the renal and mesenteric vasculature of WKY, SHR and streptozotocin (STZ)-induced diabetic rats. Angiotensin II-induced a dose-dependent pressor response in the renal
