Abstract: The present invention relates to a composition comprising 4-hexylresorcinol(4-HR) as an active ingredient for prevention or treatment of a bone disease, and a formulation thereof. The composition comprising 4-hexylresorcinol (4-HR) as an active ingredient, or an ointment thereof was found to improve bone thickness, density, and strength and control bone remodeling by promoting the differentiation of osteoblasts and suppressing the proliferation and differentiation of osteoclasts in osteoporosis-induced animal models. Thus, the composition or ointment comprising 4-hexylresorcinol (4-HR) as an active ingredient can be provided as a therapeutic agent for bone diseases including bone fracture, osteoarthritis, rheumatoid arthritis, and osteoporosis.

Abstract: The present disclosure relates to a bone graft material grafted with 4-hexylresorcinol affecting bone formation, the bone graft material which not only can rapidly promote bone formation by mixing hydrous ethanol having low concentration 4-hexylresorcinol dissolved therein and a base material for release control with distilled water or a salt-dissolved aqueous solution to obtain a mixed solution and precipitating a bone graft material into the mixed solution, thereby injecting 4-hexylresorcinol into the bone graft material, but also can have a consistent treatment effect by adjusting elution amount of 4-hexylresorcinol through the base material for release control, thereby allowing 4-hexylresorcinol to be slowly released during a treatment period.

Abstract: Disclosed is a reagent for diagnosing osteoarthritis or predicting the prognosis of osteoarthritis, the reagent containing a peptide having the amino acid sequence (CQRPPR) of SEQ ID NO: 1 as an active ingredient. The present peptide can be used to accurately diagnose osteoarthritis in its early stage based on the molecular imaging technique. The present peptide has a small molecular weight, and thus has advantages of fast clearance from the blood, effective permeation into the tissue, low immunogenicity, and low-production cost. Further, the present reagent can diagnose osteoarthritis in its early stage in which the destruction of cartilage is in a reversible phase and thus can be recovered to a normal state, thereby significantly contributing to effective treatment of osteoarthritis.

Abstract: A method for preventing or treating a bone disease, includes administering to a patient having the bone disease a pharmaceutical composition comprising glyceollin as an active ingredient. The active ingredient, glyceollin promotes degradation of the Runx2 protein in osteoblasts and inhibits the mRNA expression of Rankl in osteoblasts to prevent the differentiation of osteoclasts. Furthermore, glyceollin is capable of ameliorating osteoporosis in animal models for osteoporosis. The composition promises drug or food for prevention or treatment of not only osteoporosis but also bone diseases caused by cancer metastatic to the bone.

Abstract: The present invention relates to the use of a peptide that interacts with the ?v?3 integrin of endothelial cells. More particularly, the invention relates to a method for inhibiting endothelial cell adhesion, endothelial cell migration and/or angiogenesis, using a peptide consisting of at least 18 amino acids, comprising tyrosine-histidine (TY) or asparagines-histidine (NH), and at least three hydrophobic amino acids with bulky side chains; or equivalents thereof. Furthermore, the invention provides a method for treating or preventing angiogenesis-related diseases, using the peptide.

Abstract: The present invention relates to the novel use of a polypeptide comprising a fas-1 domain. More particularly, the invention relates to a method for the inhibition of the adhesion, migration and/or proliferation of endothelial cells, and/or for the inhibition of angiogenesis, using the polypeptide comprising the fas-1 domain, or functional equivalents thereof. Furthermore, the invention provides a method for treating or preventing angiogenesis-related diseases, using the polypeptide.

Abstract: The present invention relates to the novel use of a polypeptide comprising an isolated polypeptide comprising EMI domain, four fas-1 domains and RGD motif of ?ig-h3.
