Anticoagulant proteins from snake venoms: structure, function and mechanism.

Area of Science:

• Biochemistry
• Pharmacology
• Toxicology

Background:

• Snake venom toxins are valuable tools for physiological research and drug development.
• Blood circulation, specifically thrombosis and hemostasis, is a key target for snake venom proteins.
• Anticoagulant proteins from snake venoms have significantly advanced our understanding of blood coagulation.

Purpose of the Study:

• To review the structure, mechanism, and structure-function relationships of anticoagulant proteins found in snake venoms.
• To highlight the therapeutic potential of these anticoagulants in treating or preventing clot formation.
• To underscore the importance of ongoing research in discovering new anticoagulants.

Main Methods:

• Literature review of scientific publications on snake venom anticoagulant proteins.
• Analysis of studies detailing the molecular mechanisms of anticoagulation.
• Examination of research on structure-function relationships of these proteins.

Main Results:

• Snake venom anticoagulants function through diverse mechanisms, some with enzymatic activity and others without.
• These proteins interfere with normal blood coagulation pathways.
• Significant progress has been made in understanding their structure and function, with new discoveries continually emerging.

Conclusions:

• Snake venom anticoagulant proteins are crucial for understanding blood coagulation.
• They represent promising leads for developing novel anticoagulant drugs.
• Continued research is vital for combating thrombotic events in cardiovascular and cerebrovascular diseases.
