Lys-[Des-Arg9]Bradykinin TFA 是一种天然存在的激肽，是一种有效且高度选择性的缓激肽 B1 受体激动剂，对人，小鼠和兔子的 B1 受体的 K_i 值为 0.12 nM，1.7 nM 和 0.23 nM。Lys-[Des-Arg9]Bradykinin TFA 对 B2 受体的抑制活性较低。

Lys-[Des-Arg9]Bradykinin TFA, a naturally occurring kinin, is a potent and highly selective bradykinin B1 receptor agonist with a K i 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 low inhibitory activity on B2 receptors.

Bradykinin B1 Receptor (B1R)

Lys-[Des-Arg9]Bradykinin is formed by the proteolytic cleavage of bradykinin, exerts its effects through bradykinin B1 receptor (B1R).
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. has not independently confirmed the accuracy of these methods. They are for reference only.

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 (T 1/2 is 118-195 s). has not independently confirmed the accuracy of these methods. They are for reference only.
