bradykinin (acetate)

Bradykinin (acetate) is an active peptide that is generated by the kallikrein-kinin system. It is a inflammatory mediator and also recognized as a neuromediator and regulator of several vascular and renal functions. Enzymatically produced from kallidin in the blood, it is a powerful vasodilator that causes smooth muscle contraction, and may mediate inflammation. It has a role as a human blood serum metabolite and a vasodilator agent. It is a tautomer of a bradykinin(2+).

Lys-[Des-Arg9]Bradykinin acetate is an 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]-Bradykinin.

Sar-[D-Phe8]-des-Arg9-Bradykinin acetate is a potent and selective bradykinin B1 receptor agonist (EC50 = 9.02 nM in rabbit aorta) that is resistant to aminopeptidase, kininase I and II (ACE) and neutral endopeptidase cleavage. Exhibits hypotensive and angiogenic activity in vivo.

(Hyp³)-Bradykinin acetate is an agonist of bradykinin B2 receptor and stimulates inositol phosphate production in cultured human fibroblasts.

Des-Arg9-[Leu8]-Bradykinin acetate is a potent antagonist of the bradykinin receptor 1 (B1R) used in renal fibrosis research [1].

[Des-Arg9]-Bradykinin acetate is a selective agonist of the Bradykinin B1 receptor.

Lys-Bradykinin acetate is an endogenous bradykinin receptor agonist.

NPC 567 acetate is a bradykinin B2 antagonist and can be used in studies about the treatment of allergic airway disease.

Icatibant Acetate, an antagonist of the bradykinin B2 receptor, is used in the treatment of hereditary angioedema.

[D-Arg1,D-Phe5,D-Trp7,9,Leu11]-Substance P acetate ([D-Arg1,D-Phe5,D-Trp7,9,Leu11]-Substance P acetate (96736-12-8 free base)) is a broad spectrum neuropeptide inverse agonist and antagonist. Potent full inverse agonist for the ghrelin receptor (EC50 = 5.2 nM); diminishes constitutive ghrelin receptor signaling. Also antagonist at tachykinin, bradykinin, CCK and bombesin receptors. Induces apoptosis and inhibits cancer cell growth in vitro.

Bombinakinin M acetate is a potent bradykinin receptor agonist with high selectivity for mammalian arterial smooth muscle bradykinin receptors and is approximately 50 times more potent than bradykinin.
