Dipyridamole inhibits platelet phosphodiesterase, causing an increase in cyclic AMP with potentiation of the action of PGI 2 – opposes actions of TXA 2 Epoprostenol is a prostacyclin that is used to inhibit platelet aggregation during renal dialysis (with or without heparin) and is also used in primary pulmonary hypertension.
One primary function of thromboregulation is the control of primary hemostasis, which is the platelet aggregation process. Some thromboregulators enhance platelet aggregation and some others inhibit the process. Platelet aggregation plays a critical role in the genesis of a resulting thrombus. Adhesion should remain local, but platelet ...
Glycoprotein IIb/IIIa inhibitors are frequently used during percutaneous coronary intervention (angioplasty with or without intracoronary stent placement). They work by preventing platelet aggregation and thrombus formation. They do so by inhibition of the GpIIb/IIIa receptor on the surface of the platelets.
Tirofiban, sold under the brand name Aggrastat, is an antiplatelet medication.It belongs to a class of antiplatelets named glycoprotein IIb/IIIa inhibitors.Tirofiban is a small molecule inhibitor of the protein-protein interaction between fibrinogen and the platelet integrin receptor GP IIb/IIIa and is the first drug candidate whose origins can be traced to a pharmacophore-based virtual ...
Dipyridamole (trademarked as Persantine and others) is an antiplatelet drug of the nucleoside transport inhibitor and PDE3 inhibitor class that inhibits blood clot formation when given chronically and causes blood vessel dilation when given at high doses over a short time.
By adding methylsulfanylethylamino group at the C4 position and trifluoropropylsulfanyl at the chainlength leads to the formation of the drug cangrelor that has enhanced activity. Cangrelor has a 78% mean recovery of ADP induced platelet aggregation in rat after 20 minutes comparison to compound 1C which has a less than 10% recovery. [22]
Abciximab, a glycoprotein IIb/IIIa receptor antagonist manufactured by Janssen Biologics BV and distributed by Eli Lilly under the trade name ReoPro, is a platelet aggregation inhibitor mainly used during and after coronary artery procedures like angioplasty to prevent platelets from sticking together and causing thrombus formation within the coronary artery.
Aggregation of platelets is highly regulated by cyclic nucleotides. PDE3A is a regulator of this process, and PDE3 inhibitors effectively prevent aggregation of platelets. Cilostazol is approved for treatment of intermittent claudication and is thought to involve inhibition of platelet aggregation and also inhibition of smooth muscle ...
