Introduction of 71800-36-7 :

Lys-[Des-Arg9]Bradykinin, 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 has low inhibitory activity on B2 receptors[1][2]. In Vitro: Lys-[Des-Arg9]Bradykinin is formed by the proteolytic cleavage of bradykinin, exerts its effects through bradykinin B1 receptor (B1R)[1].
Lys-[Des-Arg9]Bradykinin (Lda-BK; 10 μM) enhances the secretion of IL-12p70 and inhibits the secretion of IL-12p40 by mature hMo-DCs. Pretreatment with Lys-[Des-Arg9]Bradykinin treatment reduces the migration of mature hMo-DCs toward medium alone, suggesting that Lys-[Des-Arg9]Bradykinin may inhibit the chemokinesis of mature hMo-DCs[1]. In Vivo: Lys-[Des-Arg9]Bradykinin (1 μg; intra-artenal injection; New Zealand White rabbits) treatment reduces peripheral vascular resistance in LPS-induced rabbits, but the effect is brief (T1/2 is 118-195 s)[3].
