  • Patent number: 7132408
    Abstract: This invention is directed to a method of preventing or treating diseases or conditions associated with platelet aggregation. The method is also directed to a method of treating thrombosis. The method comprises administering to a subject a pharmaceutical composition comprising a therapeutic effective amount of P2Y12 receptor antagonist compound, wherein said amount is effective to bind the P2Y12 receptors on platelets and inhibit ADP-induced platelet aggregation. The P2Y12 receptor antagonist compounds useful for this invention include mononucleoside 5?-monophosphates, mononucleoside polyphosphates, and dinucleoside polyphosphates of general Formula I, or salts thereof. The present invention also provides novel compounds of mononucleoside 5?-monophosphates, mononucleoside polyphosphates, and dinucleoside polyphosphates. The present invention further provides pharmaceutical formulations comprising mononucleoside 5?-monophosphates, mononucleoside polyphosphates, or dinucleoside polyphosphates.
