Abstract: The present invention relates to a novel benzamidine derivative, a process for the preparation thereof, and a pharmaceutical composition comprising the same. The benzamidine derivative of the present invention effectively inhibits osteoclast differentiation at an extremely low concentration, and greatly increases the trabecular bone volume, and thus it can be advantageously used for the prevention and treatment of osteoporosis.

Abstract: Disclosed herein is a composition for the treatment bone fracture comprising N-hydroxy-4-{5-[4-(5-isopropyl-2-methyl-1,3-thiazol-4-yl)phenoxy]pentoxyl-benzamidine, 4-{5-[4-(5-isopropyl-2-methyl-1,3-thiazol-4-yl)phenoxy]pentoxy}-benzamidine or pharmaceutically acceptable salts thereof as a medicinally effective ingredient. The composition of the present invention can significantly reduce the volume of bony callus, and increase bony density and strength of bony callus, and decrease the contents of connective tissue and cartilage tissue in bony callus, and thus promote loss and ossification of the bony callus formed during the fracture healing process. Therefore, the composition of the present invention is useful for the treatment of bone fracture.

Abstract: Disclosed herein is a composition for the treatment and prevention of allergic inflammatory diseases comprising N-hydroxy-4-{5-[4-(5-isopropyl-2-methyl-1,3-thiazol-4-yl)phenoxy]pentoxy}-benzamidine, 4-{5-[4-(5-isopropyl-2-methyl-1,3-thiazol-4-yl)phenoxy]pentoxy}-benzamidine or pharmaceutically acceptable salts. The composition exhibits excellent medicinal effects on allergic inflammatory diseases, with a great reduction in typical chronic inflammation symptoms, such as an increase of eosinophil level in bronchoalveolar lavage fluid, total leukocyte level and eosinophil level in blood, the hypertrophy or hyperplasia of bronchial epithelium due to an increase in the number of mucus cells, a reduction in alveolar surface area resulting from the hyptertrophy of alveolar walls, and the infiltration of inflammatory cells.

Abstract: The present invention relates to a radionuclide-chitosan complex solution and its preparation method, and more particularly to the radionuclide-chitosan complex solution having a viscosity of 300˜2,400 cps, comprising an aqueous chitosan solution or a freeze-dried chitosan labeled with a radionuclide. The radionuclide-chitosan complex solution according to the present invention has a stable gelation state at a target region when injected into the body while maintaining a labeling yield of radioisotope to chitosan above 99%. Side effects may be minimized and treatment efficiency may be increased when injected to a patient.

Abstract: The present invention relates to a method for preparing a radioactive film for local radioactive treatment. More particularly, the present invention relates to a method for preparing a radioactive film comprising the steps of; dissolving 0.1˜14.5 weight % of a stable nuclide and 13˜32.5 weight % of a film-forming base for the total amount of a solvent in the solvent; applying a stable nuclide solution on a release paper by a coater and drying; and irradiating a stable nuclide film with neutrons in a nuclear reactor. A method for preparing a radioactive film according to the present invention provides a radioactive film having a uniform distribution of radionuclides and an even thickness. Therefore, the therapeutic efficacy of the radioactive film for selective treatment of a lesion may be maximized by attaching the radioactive film on a patient's skin or a mucous membrane and by direct radioactive radiation.

Abstract: Disclosed is a composition for treating prostate cancer. The composition for treating prostate cancer comprises as an effective ingredient a radioisotope-chitosan complex that includes a therapeutic radioisotope emitting beta radiation and chitosan. Also, the present invention discloses a kit for preparing the composition. When directly administered to a prostate cancer tissue, the radioisotope- chitosan complex is deposited in the applied target site while not leaking from the applied target site, and strongly inhibits the growth of prostate cancer cells while minimizing the side effects of conventional therapies, including urinary incontinence, urethral stricture and rectal bleeding. In addition, the radioisotope-chitosan complex may be used as an effective therapeutic agent for hormone-independent prostate cancer that is resistant to hormone therapy.

Abstract: This invention relates to a pharmaceutical composition containing 4-[(4-thiazolyl)phenoxyl]alkoxy-benzamidine derivatives expressed by the following formula 1 for the prevention and treatment of osteoporosis and more particularly, to the use of 4-{5-[4-(5-isoproply-2-methyl-1,3-thiazol-4-yl)phenoxyl]pentoxy}-benzamidine or N-hydroxy-4-{5-[4-(5-iso-propyl-2-methyl-1,3-thiazol-4-yl) phenoxyl]pentoxy}-benzamidine expressed by the following formula 1, which is known as an antagonist of leukotriene-B4 receptor, as a pharmaceutical composition for the prevention and treatment of osteoporosis. [Formula 1], wherein, R is a hydrogen atom or a hydroxy group.

Abstract: The present invention relates to a method for preparing the crystal of human derived TRAIL protein and TRAIL receptor protein sDR5 complex and the crystal of TRAIL-sDR5 complex prepared by the method. The present invention also TRAIL relates to a three-dimensional structure of TRAIL protein in the form of complex with TRAIL receptor sDR5 as well as TRAIL protein itself, and specific residues existed in the contact central region of AA″ loop. The three-dimensional structure of TRAIL-sDR5 complex and the specific residues in the AA″ loop of the present invention can be effectively used for not only the development of TRAIL protein having the better cytotoxic activity and having the improved receptor biding affinity, which specifically kills viral infected cells or cancer cells but also molecular strategy for regulating the binding specificity between TNF and TNFR family.

Abstract: The present invention relates to a liquid suppository composition comprising diclofenac sodium, poloxamer and at least one polymer select from the group consisting of polyethylene oxide and polyvinylpyrrolidone. The composition provides the advantages of. (1) a feel of foreign matter or discomfort does not occur when the composition is rectally administered; and (2) administration is easy and after rectal administration, the composition is neither leaked out from the anus nor shifted into the end of large intestine.
