  • Publication number: 20070155995
    Abstract: An improved method of making a substituted pyrazolopyrimidine. The method comprises reacting a aminopyrazole compound or a salt thereof with a substituted 1-oxo-2-propenyl-arene(-heterocycle) or a salt thereof under acidic conditions in a reaction medium including a two-phase mixture of an aqueous solution and a water-immiscible organic liquid. Specific substituted pyrazolopyrimidines include N-[3-(3-cyanopyrazolo[1,5-a]pyrimidin-7-yl)phenyl]-N-ethylacetamide and N-methyl-N-(3-{3-[2-thienyl-carbonyl]-pyrazolo[1,5-a]-pyrimidin-7-yl}phenyl)acetamide.

  • Publication number: 20060269511
    Abstract: An organized mobile multicomponent conjugate (OMMC) and method of using to enhance binding of weakly binding compounds to a target. A lamellar structure containing at least two binding compounds is assembled under conditions in which the binding compounds self-regulate in or on the lamellar structure, forming a cooperative ensemble that is capable of binding with enhanced affinity to a complementary affinity site on a target. Each binding compound is bound to the lamellar surface, and may be connected by a linker. The OMMC may contain an effector molecule, such as a diagnostic or therapeutic agent, for administration to a patent who is then diagnosed or treated using the effector molecule.

  • Publication number: 20040180864
    Abstract: The present invention discloses novel aromatic azide derivatives and their bioconjugates for phototherapy of tumors and other lesions. The organic azides of the present invention are designed to absorb low-energy ultraviolet, visible, or near-infrared (NIR) region of the electromagnetic spectrum. The phototherapeutic effect is caused by direct interaction of nitrene, the reactive intermediate produced upon photoexcitation of the aromatic azide, with the tissue of interest. The compounds of the present invention are administered to a patient, allowed to accumulate at the site of the tumor or other lesion, and are exposed to light in order to perform a phototherapeutic procedure.
