bradykinin (29)

Bradykinin (2-9) (Des-Arg1-bradykinin)，是Bradykinin的一种氨基端截短肽类代谢物，通过Aminopeptidase P的切割作用形成。

Peptide antagonist of the B2 bradykinin receptor (pKi = 10.3); conformationally constrained cyclized analog of HOE 140. Blocks hypotension and bronchoconstriction in vivo. Displays selectivity for B2 over 29 other receptors and ion channels (pIC50 < 5.5).
