Biological Actions of Alamandine: A Scoping Review.

: This scoping review aims to comprehensively map the existing literature on the mechanisms of action of Alamandine (ALA), a peptide within the renin-angiotensin system, and its effects across various physiological systems. : Utilizing the Joanna Briggs Institute methodology, a thorough search of databases including PubMed, Embase, Scopus, and Web of Science was conducted up to 30 January 2025. The review focused on identifying studies that explore the biological and therapeutic roles of ALA in different contexts, incorporating in vivo, in vitro, and in silico research. : A total of 590 records were initially identified, with 25 meeting the eligibility criteria for inclusion in this review. China emerged as the leading contributor to the research in this area, with a significant focus on the cardiovascular system. The studies revealed that ALA exhibits a range of beneficial effects, including anti-inflammatory, vasodilatory, antifibrotic, and antiapoptotic actions. These effects are primarily mediated through the inhibition of the mitogen-activated protein kinase (MAPK) signaling pathway and modulation of the nitric oxide pathway. The review also highlighted AL's potential in mitigating oxidative stress and its implications in treating cardiovascular diseases, fibrosis, and cancer. : The findings suggest that ALA holds significant therapeutic potential, offering antihypertensive, anti-inflammatory, antifibrotic, and anticancer benefits without notable adverse effects, warranting further research to explore its full potential and mechanism of action.
