Bradykinin 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.

Fasitibant chloride hydrochloride (MEN16132) is a potent, selective, high affinity, and longlasting nonpeptide bradykinin B2 (BK2)?receptor antagonist. Fasitibant chloride hydrochloride has?proinflammatory effects and can be used for the research of osteoarthritis and rheumatoid arthritis, et al.

Retrobradykinin has the reverse sequence of Bradykinin. Retrobradykinin has no significant kinin activity and can be used as a negative control for Bradykinin.

Lys-[Des-Arg9]Bradykinin TFA, a naturally occurring kinin, is a potent and highly selective bradykinin B1 receptor agonist with a Ki of 0.12 nM, 1.7 nM and 0.23 nM for human, mouse and rabbit B1 receptors, respectively. Lys-[Des-Arg9]Bradykinin TFA has lowy activity on B2 receptors.

[Hyp3]-Bradykinin, naturally occurring peptide hormone, is a bradykinin receptor agonist. [Hyp3]-Bradykinin interacts with B2-bradykinin receptors and stimulates inositol phosphate production in cultured human fibroblasts.

Deucrictibant is a potent bradykinin receptor antagonist. Bradykinin receptors are cell surface, G-protein coupled receptors of the seven-transmembrane domained family.

Fulimetibant is a bradykinin receptor antagonist.

Bombinakinin M is a bradykinin receptor agonist with contractile activity in the guinea pig ileum.

MEN 11270, a cyclic decapeptide, is a B2 kinin receptor antagonist. MEN 11270 bound with high-affinity to the B2 kinin receptor constitutively expressed by WI38 human fibroblasts, inhibiting 3H-bradykinin (BK) with pKi of 10.3.
