资料参考

Bradykinin (acetate) is a well-known 9-amino acid endogenous vasoactive peptide and a systemic vasodilator [1].

Bradykinin is a potent endothelium-dependent vasodilator, leading to the reduction in blood pressure. It also induces contraction of non-vascular smooth muscle in the bronchus and gut, increases vascular permeability and is also involved in the mechanism of pain. Bradykinin is an inflammatory mediator. The Bradykinin B1 receptor is expressed only as a result of tissue injury and plays a role in inflammation. The Bradykinin B2 receptor is constitutively expressed and participates in bradykinin's vasodilatory role.

In cultured endothelial cells, bradykinin promoted a rapid dissociation of the eNOS:B2 receptor complex [2]. In the mouse gastrointestinal tract and pancreas, bradykinin stimulated extravasation from postcapillary venules by two- to sevenfold by interacting with B2 receptors and stimulating tachykinin release from sensory nerves [3].

In healthy men, bradykinin (100-3200 ng/kg min) dose-related increased plasma concentrations of 6-oxo-PGF1a , the stable hydrolysis product of prostacyclin (PGI2). So bradykinin may have a use as a probe of PG12 production in vivo in pathological states [1].

试验操作

Cell experiment:[1]

Cell lines

Human umbilical vein endothelial cells and monocytes

Reaction Conditions

10-8~ 10-5mol/l bradykinin for 1 h pretreatment

Applications

Exogenous bradykinin markedly inhibited tissue factor expression in mRNA and protein level induced by lipopolysaccharides in a dose-dependent manner.

Animal experiment:[1]

Animal models

C57/BL6 mice

Dosage form

10 mg/kg/d

Injected intraperitoneally for 3 days ahead of inferior cava vein ligation and for another 2 days after surgical procedure

Applications

Intraperitoneal injection of C57/BL6 mice with bradykinin inhibited the thrombus formation induced by ligation of inferior vena cava.
