BACKGROUND: Thrombotic diseases remain a major global health burden. Current anticoagulants are often limited by bleeding risks and narrow therapeutic windows, largely due to their single-target mechanisms. In contrast, medicinal leeches secrete diverse peptides that naturally and synergistically modulate multiple steps of the hemostatic system.
METHODS: This paper systematically reviews published biochemical, structural, functional, and omics studies on leech-derived anticoagulant peptides, classifying them according to their molecular targets and antithrombotic mechanisms.
RESULTS: Leech-derived peptides act synergistically at multiple key points of the coagulation cascade: (1) they inhibit platelet adhesion and aggregation by blocking the vWF-collagen interaction or suppressing GPIIb/IIIa; (2) they directly inhibit core coagulation proteases, such as thrombin and factor Xa; and (3) they interfere with fibrin stabilization and promote its dissolution by inhibiting factor XIIIa or modulating the fibrinolytic and intrinsic protease systems. From a molecular perspective, multispecies omics analyses have revealed a significant expansion of antithrombotic gene families and identified numerous novel peptide candidate genes.
CONCLUSIONS: Leech-derived peptides provide a unique natural platform for multi-target anticoagulation and represent promising leads for next-generation antithrombotic agents. Combining traditional purification with genomics-guided discovery will accelerate mechanism elucidation, structural optimization, and translational development.
