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.[1]

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.[2] It has also been used as an analyte in nanostructure-initiator mass spectrometry and matrix-assisted laser desorption/ionization (MALDI).[3]

Biochem/physiol Actions

Bradykinin Fragment 1-8 is a selective B1 bradykinin receptor agonist.[4] 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.[5]

Several cytokines and LPS regulate the population of the B1 receptors (B1Rs) for kinins; these are responsive to des-Arg9-bradykinin (BK) and Lys-des-Arg9-BK. B1R activation contributes to inflammatory vascular changes and pain. Aortic rings isolated from normal rabbits and incubated in
