  • Publication number: 20110033474
    Abstract: The present invention provides methods and compositions for preventing platelet aggregation and for treating individuals suffering from conditions or undergoing procedures that may result in unwanted platelet aggregation. In particular the invention provides to methods and compositions for arterial vessel pacification. The methods are based on the administration of a therapeutically effective amount of a glycoprotein IIb/IIIa receptor antagonist, e.g., xemilofiban. The treatment may commence prior to a medical or surgical procedure or an outbreak of a condition, either of which results in the activation of platelets that may lead to thrombus formation, and may continue thereafter.

  • Patent number: 6861448
    Abstract: Disclosed are compounds that inhibit the microbial NAD synthetase enzyme. For example, disclosed are compounds of the formula Ar1—X—Ar2—Y—L—Z—Q, wherein Q is Q1Ar3 or Ar3Q1; Ar1, Ar2, and Ar3 are independently aryl or heteroaryl, optionally substituted with one or more substituents; X, Y, and Z are independently selected from the group consisting of a covalent bond or groups containing one or more of C, H, N, O, S atoms; L is a linker and Q1 is an alkylenyl, alkylenyl carbonyloxy alkyl, or alkylenyl carbonylamino alkyl group, optionally having a substituent; a covalent bond; a group containing amidine or guanidine function wherein the amidine or guanidine may be optionally N-substituted with an alkyl; or a zwitterion; or a pharmaceutically acceptable salt thereof.
