bradykinin (16)

Bradykinin (1-6) is an amino-truncated Bradykinin peptide and a stable metabolite of Bradykinin, cleaved by carboxypeptidase Y (CPY). This fragment of Bradykinin activates pain receptors and induces smooth muscle contraction.

Lys-[Des-Arg9]Bradykinin acetate (71800-36-7 free base) 是一种内源性强效和高选择性的缓激肽 B1 受体激动剂（对人 B1 和 B2 受体的 Ki 值分别为 0.12 和 > 30000 nM）。降低体内外周血管阻力的降压药。比 [Des-Arg9]-缓激肽强 16 倍。

EDHF (endothelium-derived hyperpolarizing factor) is an unidentified mediator released from vascular endothelial cells in response to acetylcholine and bradykinin which is distinct from the NOS- (nitric oxide) and COX-derived (prostacyclin) vasodilators.[1],[2]Cytochrome P450 (CYP450) metabolism of polyunsaturated fatty acids produces epoxides such as (±)14(15)-EET which are prime candidates for the actual active mediator.[3] However, the CYP450 metabolites of eicosapentaenoic acid and docosahexaenoic acid have been little studied relative to arachidonate epoxygenase metabolites. (±)16(17)-EpDPA is the DHA homolog of (±)14(15)-EpETrE, derived via epoxidation of the 16,17-double bond of DHA. The EDHF activity of (±)16(17)-EpDPA has not yet been determined. The epoxygenase metabolites of DHA have also been detected in a mouse inflammation model.[4]

Endogenous potent and highly selective bradykinin B1 receptor agonist (Ki values are 0.12 and > 30000 nM at human B1 and B2 receptors respectively). Hypotensive agent that reduces peripheral vascular resistance in vivo. 16-fold more potent than [Des-Arg9]
