Echistatin is primarily utilized in biomedical research due to its potent inhibitory effects on platelet aggregation. It is extensively studied for its ability to block integrin receptors, particularly αIIbβ3, which plays a critical role in blood clot formation. This makes it a valuable tool in understanding thrombosis and developing antiplatelet therapies. Additionally, echistatin is employed in cancer research to investigate its potential in inhibiting angiogenesis, as integrins are involved in tumor growth and metastasis. Its applications also extend to studying cell adhesion and migration processes, providing insights into wound healing and tissue regeneration.
