标题 :Pyrogallol synthesis of anti-atherogenic furochromones
发明人：GAMMILL RONALD B
权利人:UPJOHN CO
摘要:The present invention provides a total synthesis of known intermediates useful in the synthesis of khellin and antiatherosclerotic analogs thereof from pyrogallol. Pyrogallol is converted to 3,6,7-benzofurantriol triacetate using zinc chloride and chloracetanitrile, then catalytically reduced and deactoxylated at the 3 position to yield the corresponding 2,3-dihydrofuran. This substance is subjected to a Fries rearrangement to the corresponding diol, the phenolic hydroxyl group of which is then selectively alkylated. This yields 6-hydroxy-7-alkoxy-5-benzofuranyl methyl ketone, a known intermediate for the production of 4-desmethoxy khellin and analogs thereof. This compound is then selectively alkoxylated at the 4 position using lead tetraacetate or thallium (III) nitrate in an alkanol solvent to yield known chemical intermediates in the preparation of khellin and analogs thereof.

摘要:Novel methods of synthesis of chelator-targeting ligand conjugates, compositions comprising such conjugates, and therapeutic and diagnostic applications of such conjugates are disclosed. The compositions include chelator-targeting ligand conjugates optionally chelated to one or more metal ions. Methods of synthesizing these compositions in high purity are also presented. Also disclosed are methods of imaging, treating and diagnosing disease in a subject using these novel compositions, such as methods of imaging a tumor within a subject and methods of diagnosing myocardial ischemia.

标题 :Inhibition of cell proliferation and matrix synthesis by antioxidants and NAD(P)H oxidase inhibitors
发明人：SHI YI; ZALEWSKI ANDREW
摘要:The present invention is directed to a method for the prophylactic and therapeutic treatment of diseases or disorders associated with the abnormal proliferation and extracellular matrix synthesis of smooth muscle cells (SMC) and fibroblasts due to activation of NAD(P)H and/or increased ROS generation. The method involves the administration of an NAD(P)H oxidase inhibitor(s) and/or antioxidant(s) to a mammal in an amount sufficient to treat the disease or disorder prophylactically or therapeutically. The NAD(P)H oxidase inhibitor inhibits the synthesis or translocation of NAD(P)H subunits, thereby blocking the generation of intracellular reactive oxygen species (ROS) and thus the proliferation and extracellular matrix synthesis of SMC and fibroblasts. Similarly, the administration of antioxidants blocks the generation of intracellular ROS, thereby inhibiting SMC and fibroblast proliferation and extracellular matrix synthesis. In addition to the prevention and treatment of vascular disease, such as atherosclerosis, graft disease, and restenosis, NAD(P)H oxidase inhibitors and antioxidants may be useful for the prevention and treatment of other conditions by decreasing cell proliferation and extracellular matrix synthesis associated therewith. These conditions include arthritis, keloid formation, cancer, tissue and organ fibrosis, and complications related to organ transplantation, metabolic syndrome, and radiation therapy.

摘要:The invention relates to the stimulation of the synthesis and of the activity of an isoform of lysyl oxidase, and more particularly of the LOXL (lysyl oxidase-like) isoform. The invention relates notably to a method of identifying an active principle which stimulates the formation of elastic fibers. The aim of the invention is mainly to provide such a method of identification so as to provide compositions which enable stimulating the formation of elastic fibers.

标 题 :Combinations of a cyclooxygenase-2 selective inhibitor and a TNFalpha antagonist and therapeutic uses therefor
发明人：BENNETT DENNIS A
权利人:PHARMACIA CORP
摘要:A method for the prevention, treatment, or inhibition of pain, inflammation, or inflammation-related disorder and for the prevention, treatment, or inhibition of a cardiovascular disease or disorder in a subject that is in need of such prevention, treatment or inhibition, involves the administration to the subject of a cyclooxygenase-2 selective inhibitor or prodrug thereof and a TNFα antagonist. A method can also involve the treatment, prevention, or inhibition of cancer in a subject in need of such treatment, prevention, or inhibition, by administering to the subject a cyclooxygenase-2 selective inhibitor or prodrug thereof and a TNFα antagonist which is selected from the group consisting of a compound that affects the synthesis of TNFα, a compound that inhibits the binding of TNFα with a receptor specific for TNFα, and a compound that interferes with intracellular signaling triggered by TNFα binding with a receptor. Compositions, pharmaceutical compositions and kits that can be used with the methods are also described.
