Discovery of Inhibitors of Insulin-Regulated Aminopeptidase as Cognitive Enhancers

open access: yesInternational Journal of Hypertension, 2012
The hexapeptide angiotensin IV (Ang IV) is a metabolite of angiotensin II (Ang II) and plays a central role in the brain. It was reported more than two decades ago that intracerebroventricular injection of Ang IV improved memory and learning in the rat ...

The emerging multifunctional roles of ERAP1, ERAP2 and IRAP between antigen processing and renin-angiotensin system modulation

open access: yesFrontiers in Immunology, 2022
The Endoplasmic Reticulum Aminopeptidase 1 and 2 (ERAP1 and ERAP2) and Insulin Regulated Aminopeptidase (IRAP) are three M1 zinc metalloproteases whose role in antigen processing is the refining of peptidome either in the Endoplasmic reticulum (ERAP1 and

Comparative studies on angiotensins. IV. Structure of snake (Elaphe climocophora) angiotensin.

open access: yesChemical and Pharmaceutical Bulletin, 1977
Three kinds of snake angiotensins have been isolated from the incubation product of snake (Elaphe climocophora) kidney extract with homologous plasma. The amino acid sequences were deduced by dansyl method as follows : Asp-Arg-Val-Tyr-Val-His-Pro-Phe X-Asx-Arg-Val-Tyr-Val-His-Pro-Phe-Tyr X-Asx-Arg-Val-Tyr-Val-His-Pro-Phe-Tyr-Leu Tyrosine in position 9 ...

β-Homo-amino Acid Scan of Angiotensin IV

open access: yes, 2016
Angiotensin IV, a metabolite of angiotensin II, inhibits the enzyme insulin regulated aminopeptidase or IRAP and also, although with lower potency, aminopeptidase-N (AP-N).

AngIV-Analog Dihexa Rescues Cognitive Impairment and Recovers Memory in the APP/PS1 Mouse via the PI3K/AKT Signaling Pathway

open access: yesBrain Sciences, 2021
The renin-angiotensin system (RAS) is a paracrine RAS within the central nervous system (CNS) and is closely related to Alzheimer’s disease (AD). The endogenous hexapeptide angiotensin IV (Ang IV), an important component of the brain RAS, was found to ...

LVV-hemorphin 7 and angiotensin IV in correlation with antinociception and anti-thermal hyperalgesia in rats

open access: yes, 2012
[[abstract]]Hemorphins, a family of atypical endogenous opioid peptides, are produced by the cleavage of hemoglobin β-chain. Hemorphins were proved to bind to the μ-opioid receptors (agonist) and angiotensin IV receptors (insulin-regulated aminopeptidase;
