Protective Effects of Phoenixin-14 Administration Against Renal Ischemia/Reperfusion Injury in Rats.

Phoenixin (PNX), identified in the rat hypothalamus in 2013, has two bioactive isoforms with 14 and 20 amino acids. Initially studied for its role in reproductive regulation, research has since shown that PNX also prevents visceral pain, enhances memory, and aids heart tissue recovery. However, its role in kidney tissue remains unclear.

Myrtenal Pretreatment Exerts a Protective Effect Against Renal Ischemia-Reperfusion Injury in Rats.

An Experimental Insight Into the Role of Agomelatine in Renal Ischemia/Reperfusion Injury.

Acute kidney injury (AKI) is one of the leading causes of chronic kidney disease and accounts for 50%-75% of mortality following renal pathologies or organ transplantation. Ischemia‒reperfusion injury (IRI) involves an interrupted blood supply to organs and the kidney; IRI exacerbates AKI development. Owing to several pharmacological treatment methods, AKI still has a poor prognosis, and novel therapeutic options are needed.

Phosphazene Tripeptide Conjugates: Design, Synthesis, In Vitro Cytotoxicity and Genotoxicity, Molecular Interactions in Binding Pockets on Human Breast and Colon Cancer Cell Lines.

The biological activity of both cyclophosphazenes and peptides makes these compounds important for new studies in medicinal chemistry. For this purpose, five different phosphazene-peptide conjugates synthesized from dichlorocyclotriphosphazene and tyrosine-containing tripeptides.
