    Aprotinin is a bovine pancreatic trypsin inhibitor (BPTI) inhibitor which inhibits trypsin and chymotrypsin with Kis of 0.06 pM and 9 nM, respectively.

    IC50 & Target

    Ki: 0.06 pM (Trypsin), 9 nM (Chymotrypsin)[1]


    Aprotinin, a serine protease inhibitor isolated from bovine lung, is a complex protease inhibitor that is an antifibrinolytic, inhibits contact activation, and decreases the inflammatory response to cardiopulmonary bypass[2]. Aprotinin inhibits trypsin (bovine, Ki= 0.06 pM), chymotrypsin (bovine, Ki= 9 nM), plasmin (human, 0.23 nM)[1]. Aprotinin is also a competitive protein inhibitor of NOS activity. It inhibits NOS-I and NOS-II with Ki values of 50 μM and 78 μM, respectively[3]. Aprotinin significantly inhibits fibrinolysis with an IC50 of 0.16±0.05 μM[4].

    High dose aprotinin can reduce blood loss and transfusion requirements associated with primary cardiac procedures such as coronary artery bypass graft (CABG) or heart valve replacement surgery[5]. Aprotinin inhibits thrombus formation in a dose-dependent manner. Aprotinin at a dose of 1.5 mg kg-1 (bolus) and 3 mg kg-1 h-1 infusion (maintenance infusion) causes a tendency towards a reduction in bleeding time. Aprotinin significantly reduces the bleeding time starting at a dose of 3 mg kg-1 bolus plus 6 mg kg-1 h-1 showing a reduction of approximately 84%±2.9%. At the highest dose of 5 mg kg-1 and 10 mg kg-1 h-1, the strongest effects are observed[4]. Aprotinin may affect tumor necrosis factor-alpha (TNF) levels. Soluble TNFRI levels are significantly increased following I/R in the aprotinin treated wild type mice and not detected in all TNFRInull mice[6].

    Rats: Male Wistar rats (180-220 g) are used in the study. Aprotinin is dissolved in physiological saline. Aprotinin is administered by bolus injection followed by a maintenance infusion. The doses given are 1.5 mg kg-1 and 3 mg kg-1 h-1, 3mg kg-1 and 6 mg kg-1 h-1 up to 5 mg kg-1 and 10 mg kg-1 h-1. Plasma concentrations for the two agents are assessed by pharmacokinetic studies in rats[4].

    Mice: An intact mouse model of ischemia/reperfusion (30 min-I/60 min-R) is used and left ventricular peak + dP/dt is measured in wild type mice (WT, C57BL/6; n=10), WT mice with aprotinin (4mL/kg; n=10), transgenic mice devoid of the TNFRI (TNFRInull; n=10), and TNFRInull with aprotinin (n=10)[6].

    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
