Bradykinin is an endogenous vasodilator that is also involved in inflammation.1,2 It is formed from kininogen via cleavage of high molecular weight kininogen (HMWK) by kallikrein or prekallikrein in a Factor XIIa-dependent or -independent manner.3 Bradykinin binds to the bradykinin B2 receptor (IC50 = 0.54 nM in COS-7 cells expressing the human receptor) and acts as an agonist but does not bind the bradykinin B1 receptor (Ki = >10,000 nM in HEK293 cells expressing the human receptor).4,5 It stimulates arachidonic acid release in CHO cells expressing the human bradykinin B2 receptor (EC50 = 0.7 nM).4 Bradykinin (100 nM) induces relaxation of isolated porcine coronary arterial rings precontracted with acetylcholine or phorbol 12,13-dibutyrate .1 It induces hyperalgesia in mice when administered at a dose of 1 µg/paw, an effect that can be reversed by the bradykinin B2 antagonist icatibant .2 Plasma levels of bradykinin are increased in patients during an acute attack of angioedema.6

计算结果:
工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
