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.

ACE inhibitors and ARBs (angiotensin receptor blockers) have been shown to attenuate radiation injuries in animal models of lethal gamma irradiation. These two classes of drug act by curtailing the actions of angiotensin II-linked inflammatory pathways that are up-regulated during

An earlier study showed that des-aspartate-angiotensin I (DAA-I) attenuated the pressor action of angiotensin III in aortic rings of the spontaneously hypertensive rat (SHR) but not the normotensive Wistar Kyoto (WKY) rat. The present study investigated similar properties of DAA-I

L6 skeletal muscle cells overexpressed ICAM-1 when treated with H2O2. Maximum effect was observed at 200 μM H2O2. Des-aspartate-angiotensin I (DAA-I) concentration-dependently attenuated the overexpression. Maximum attenuation occurred at 10(-10) M DAA-I. H2O2 activated NFκB and its translocation into the
