  • Patent number: 7749980
    Abstract: The present invention is directed to a method of treating pain. The method comprises administering to a subject a pharmaceutical composition comprising an effective amount of a P2X receptor antagonist. The methods of the present invention are useful in reducing pain, such as traumatic pain, neuropathic pain, organ pain and/or pain associated with diseases. The P2X receptor antagonists useful for this invention are non-nucleotide compounds of general Formula I. Compounds of Formula I can be used alone to treat pain. Compounds of Formula I can also be used in conjunction with other therapeutic agents or adjunctive therapies commonly used to treat pain, thus enhancing the therapeutic effect of pain reduction.

  • Patent number: 7618949
    Abstract: The present invention provides a P2Y12 receptor antagonist compound-eluting stent, wherein the stent is coated with one or more P2Y12 receptor antagonist compounds or a pharmaceutically acceptable salt, solvate, or hydrate thereof. When the stent is placed in a narrowed or damaged arterial vessel, a therapeutically effective amount of the P2Y12 receptor antagonist compound is eluted continuously from the stent to the local environment of the stent. The P2Y12 receptor antagonist compound-eluting stents are useful in preventing thrombosis and restenosis, and are effective in inhibiting the contraction of vascular smooth muscle cells, inhibiting cell proliferation, and reducing inflammation.

  • Patent number: 7612047
    Abstract: The present invention relates to mononucleoside phosphate compounds that have the benefits of a dinucleotide pharmaceutical. These mononucleoside phosphates can be made from a mononucleotide that has been modified by attaching a degradation-resistant substituent on the terminal phosphate of a polyphosphate mononucleotide. By attaching this degradation-resistant substituent, the stability from degradation matches or exceeds those of certain dinucleotides. The mononucleoside phosphate compounds of the present invention are useful in preventing and treating epithelial tissue diseases or diseases or disorders associated with platelet aggregation.
