DT-678
DT-678 is an orally active antiplatelet and antithrombotic inhibitor. DT-678 is a conjugate formed by linking the active metabolite of Clopidogrel (HY-15283) with 3-nitropyridine-2-thiol via a mixed disulfide bond. DT-678 does not rely on CYP2C19 for activation, and directly releases active substances via thiol exchange reactions in vivo, exhibiting superior efficacy over Clopidogrel. DT-678 can be used in research related to acute coronary syndrome and thrombosis.

Biological Activity
DT-678 (0.3-3 mg/kg; i.v.; single dose) reduces carotid artery thrombus weight by 42%, 68%, and 81%, respectively, in rabbits with FeCl3-induced arterial thrombosis[1].
DT-678 (1 mg/kg; i.v.; single dose) inhibits ADP-induced platelet aggregation by 72% in rabbits, with a 1.2-fold prolongation of bleeding time[1].
DT-678 (0.1-3.0 mg/kg; i.v.; single dose) dose-dependently inhibits ADP-induced rabbit platelet activation and aggregation, without significantly prolonging tongue bleeding times at equally effective antiplatelet doses[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
