  • Patent number: 7749981
    Abstract: The present invention provides a drug-eluting stent, wherein the stent is coated with one or more non-nucleotide 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: 7691825
    Abstract: The present invention provides compounds of the formula wherein R1, R2, R3 and n have meaning as described in the specification, methods for their preparation, and pharmaceutical compositions containing them. The compounds of formula (I) are adenosine A2B receptor agonists and, thus, may be employed for the treatment of diseases in mammals that are mediated by the A2B receptor including, but not limited to, septic shock, cystic fibrosis, impotence, diarrhea, and cardiac diseases. Cardiac diseases include hyperplasia consequent to hypertension, arteriosclerosis, and heart attack. The present invention also provides methods for the induction of pharmacological stress to facilitate coronary imaging of areas of ischemia by employing compounds of formula (I). The compounds of formula (I) may be labeled, e.g., with radioactive isotopes, and therefore are useful in kinetic binding experiments.
