Abstract
Provided is an earthworm protein peptide for preparing a medicine for treating a thrombotic disease. The earthworm protein peptide is any one selected from a group consisting of Leu-Val-Thr-Leu-Gly-Asn-Glu (SEQ ID NO.: 1), Leu-Leu-Ala-Pro-Pro (SEQ ID NO: 2), Leu-Leu-Pro-Ala-Pro (SEQ ID NO: 3) and Thr-Val-Ala-Pro-Phe (SEQ ID NO: 4). The earthworm protein peptide can significantly inhibit the thrombin activity, thus achieving the anticoagulant effect. In vivo, the earthworm protein peptide has a significant inhibitory effect on carrageenan-induced rat tail thrombosis; and in vitro and in vivo studies of rats with thrombus, the earthworm protein peptide provided by the present invention shows good anticoagulant effects. The earthworm protein peptide has effects of thrombosis inhibition, thrombolysis, anticoagulation and fibrinolysis promotion, and can effectively prevent and treat thrombotic disease.
