The invention discloses a hemostatic
peptide capable of targeting to a bleeding focus as well as a preparation method and application of the hemostatic
peptide, and the hemostatic
peptide is characterized in that the
amino acid sequence of the hemostatic peptide is RKLFFVRTA. According to the present invention, the key
amino acid sequence combined with TF in the blood
coagulation factor VII (FVII) is adopted as the basis for modification, the exposed TF (blood coagulation starting factor) after the
blood vessel injury is specially identified, the specific expression of the TF at the bleeding site is adopted to achieve the precise targeting, the interference on the
normal blood vessel is reduced, and the unnecessary
thrombus risk is reduced from the source.
