Biochem/physiol Actions

The bradykinin (BK) fragment (1-5) (RPPGF) is among the most stable of naturally occurring metabolites. It may be used as a marker for BK production in vivo. It is known that an intact Arg residue in the C-terminus is required for biological activities. BK 1-5 is the minimal peptide that inhibited α-thrombin-induced platelet aggregation and secretion and calcium mobilization. It also prevented α-thrombin from cleaving the thrombin receptor peptide, NATLDPRSFLLR, between arginine and serine. Such antithrombin activities of BK 1-5 may contribute to the cardioprotective nature of kinins.

M T Nieman et al.
Journal of thrombosis and haemostasis : JTH, 6(5), 837-845 (2008-03-05)
Novel pentapeptides called Thrombostatin FM compounds consisting mostly of D-isomers and unusual amino acids were prepared based upon the stable angiotensin converting enzyme breakdown product of bradykinin - RPPGF. These peptides are direct thrombin inhibitors prolonging the thrombin clotting time
Marvin T Nieman et al.
FEBS letters, 579(1), 25-29 (2004-12-29)
The angiotensin converting enzyme breakdown product of bradykinin, bradykinin 1-5 (RPPGF), inhibits thrombin-induced human or mouse platelet aggregation. RPPGF binds to the exodomain of human protease-activated receptor 1 (PAR1). Studies determined if RPPGF also binds to the exodomain of human

Arteriosclerosis, thrombosis, and vascular biology, 25(11), 2435-2440 (2005-09-17)
Angiotensin-converting enzyme inhibition (ACEI) increases vascular tissue plasminogen activator (t-PA) release through endogenous bradykinin (BK). We tested the hypothesis that gender influences the effect of ACEI on t-PA release. We measured the effect of intra-arterial enalaprilat (0.33 microg/min per 100
Elizabeth A Girnys et al.
Bioorganic & medicinal chemistry, 19(24), 7425-7434 (2011-11-08)
The serine protease thrombin plays several key roles in the clotting cascade within the hemostatic system, such as in fibrin formation and platelet activation. Thus, development of an inhibitor that binds to the enzyme's active site (a direct thrombin inhibitor)
A A Hasan et al.
Thrombosis and haemostasis, 82(3), 1182-1187 (1999-09-24)
Thrombostatin (RPPGF), an angiotensin converting enzyme metabolite of bradykinin, is an inhibitor of alpha-thrombin's ability to activate platelets. We examined the in vivo pharmacokinetics and pharmacodynamics of thrombostatin in rabbits and its ability to inhibit coronary thrombosis induced by electrolytic
