Cyproheptadine is a potent and orally active 5-HT2A receptor antagonist, with antidepressant and antiserotonergic effects. Cyproheptadine has antiplatelet and thromboprotective activities. Cyproheptadine can be used for the research of thromboembolic disorders[1][2].
Cyproheptadine (0.01-100 nM; 1 minute) dose-dependently inhibits serotonin-enhanced ADP-induced mouse platelet aggregation in vitro[2].
Cyproheptadine (10 nM) has the ability to inhibit 15 µM serotonin-enhanced ADP-induced (1 µM) tyrosine phosphorylation in platelets in vitro[2].
Cyproheptadine inhibits human platelet PS exposure (Annexin V), P-selectin, and GPIIb-IIIa (PAC-1 binding) activation in vitro[2].
Cyproheptadine can be used in animal modeling to construct diabetes models.Cyproheptadine (1 mg/kg; i.p.; daily, for 5 days; C57BL/6 mice) exerts thromboprotective properties in vivo[2].
