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.

The present study investigated the hypoglycemic action of des-aspartate-angiotensin I (DAA-I), a metabolite of angiotensin I, in two animal models of type 2 diabetes. The rationale was based on our earlier studies demonstrating that DAA-I acts on the angiotensin AT(1)

Journal of applied toxicology : JAT, 31(6), 568-578 (2010-11-10)
The present study investigated the protective actions of des-aspartate-angiotensin I (DAA-I) in mice that were intranasally administered 2-chloroethyl ethyl sulfide (CEES), a half sulfur mustard. The protection was dose-dependent, and an oral dose of 75 mg kg⁻¹ per day administered

DAA-I (des-aspartate-angiotensin I), an endogenous angiotensin, had been shown earlier to ameliorate animal models of cardiovascular diseases via the angiotensin AT1 receptor and prostaglandins. The present study investigated further the action of DAA-I on the release of PGE2, PGI2, PGF2α

Regulatory peptides, 120(1-3), 15-22 (2004-06-05)
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

PloS one, 10(9), e0138009-e0138009 (2015-09-18)
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
