3 results about "Induced platelet aggregation" patented technology

This invention relates to the fields of molecular biology and biomedicine, disclosing plasma-active peptides with antithrombotic effects and their uses. The invention obtains various active peptides from plasma through screening and solid-phase synthesis, and confirms their biological activity through in vitro platelet aggregation experiments and in vivo arterial thrombosis model experiments. Results show that peptides 1957, 1960, and 1961 significantly inhibit collagen-induced platelet aggregation, exhibiting good antiplatelet activity; animal experiments show that peptides 1955, 1957, 1960, and 1961 significantly inhibit arterial thrombosis. These active peptides are derived from endogenous plasma components, belonging to natural antithrombotic substances, possessing good physiological compatibility and safety advantages, and reducing the risk of immunogenicity and adverse reactions. These peptides can exert antithrombotic effects without relying on traditional antiplatelet drugs, providing a new source of active molecules and treatment options for the prevention and treatment of thrombotic diseases.

The application discloses a cinnoline PAR4 antagonist and medical application thereof. The application relates to a compound of formula (I), stereoisomers, tautomers, pharmaceutically acceptable salts, esters, solvates or prodrugs thereof. The compound of the application can inhibit and prevent platelet aggregation induced by PAR4, can be used for treating and preventing thromboembolic diseases, and thus can be used as an anti-platelet drug.
