摘要:
Disclosed herein is a biomolecule comprising a synthetic peptide for targeting thrombus, a pharmaceutical composition comprising the same, and uses thereof in the treatment of thromboembolism-related diseases. According to embodiments of the present disclosure, the synthetic peptide having the amino acid sequence of SEQ ID NO: 1, 2, or 3 exhibits a binding affinity and specificity to thrombus. Thus, the synthetic peptide may serve as a targeting element for delivering a therapeutic agent (e.g., an anticoagulant agent or a thrombolytic agent) to the thrombus thereby improving the therapeutic safety and efficacy of the therapeutic agent.
