Arg-Pro-Pro-Gly-Phe-Ser-Pro-Phe

General description

Bradykinin Fragment 1-8, also known as des-Arg9-bradykinin, is produced by the cleavage of bradykinin at 8-9 position by carboxypeptidase N.

Application

Bradykinin Fragment 1-8 acetate salt hydrate has been used as a Bradykinin 1 receptor (B1R) agonist to investigate the expression and the role of B1R, in mediating neuronal injury under the chemical neurotoxicity paradigm in PC12 cell lines. It has also been used as an analyte in nanostructure-initiator mass spectrometry and matrix-assisted laser desorption/ionization (MALDI).

Biochem/physiol Actions

Bradykinin Fragment 1-8 is a selective B1 bradykinin receptor agonist. It promotes the release of nitric oxide, prostacyclin, endothelium-derived hyperpolarizing factor in the endothelium. des-Arg9-bradykinin also promotes vasodilatation and increases blood flow in the peripheral circulation.

In response to bradykinin, phosphorylated MAP kinases (ERK-1 and ERK-2) were abundantly increased in HEK 293 cells, which overexpress the rat B2 kinin receptor. In a similar way des-Arg9-bradykinin stimulation of B1 kinin receptor-overexpressing HEK 293 cells caused activation of
