1.MECHANISM OF ACTION

The peptide exerts its effects by binding to and activating the APJ receptor, which couples primarily to the Gi/o protein. This leads to inhibition of adenylate cyclase, a reduction in intracellular cAMP levels, and activation of alternative signaling pathways such as ERK1/2 phosphorylation and Akt activation. This signaling cascade results in vasodilation, positive inotropic effects on the heart, modulation of angiogenesis, and regulation of fluid balance and glucose metabolism.

2.PRODUCT INDICATIONS

Apelin-15 (63-77) is indicated for research applications in cardiovascular physiology, metabolic disorders, and endocrinology. It is used in studies of vasodilation and blood pressure regulation, heart failure models, angiogenesis, fluid and electrolyte homeostasis, and insulin sensitivity. The peptide serves as a key reagent for in vitro receptor binding and functional assays, as well as in vivo investigations into its therapeutic potential for conditions like hypertension, heart failure, and diabetes.

3.CLINICAL EFFICACY OF PRODUCT

While Apelin-15 (63-77) itself is not an approved therapeutic, preclinical and early clinical studies have demonstrated its promising effects, including reducing vascular resistance, improving cardiac output in heart failure models, and enhancing glucose uptake. These findings have established the Apelin/APJ system as a validated therapeutic target, driving the development of stable Apelin analogs and APJ agonists currently in preclinical and early clinical investigation for cardiovascular and metabolic diseases.
