摘要:
Compounds of the formula wherein X in each of formulas (1) and (2) represents a substituted or unsubstituted alkylene, alkenylene, or alkynylene linker of 2-6C; Y is of the formula or a stereoisomer thereof, wherein R1 is substituted or unsubstituted alkyl; each R2 is independently H, hydroxy, alkoxy (1-6C) or lower alkyl (1-4C); R3 is H, hydroxy, or alkoxy (1-6C); or Y is of the formula wherein each n is 1, Z is N, K comprises a substituted or unsubstituted aromatic carbocyclic or heterocyclic ring system which may optionally be spaced from the linkage position shown in formula (7) by a linker of 1-2C, or in formula (7), Z may be spaced from the carbon bonded to X by ═CR6— wherein R6 is H or linear, branded or cyclic alkyl (1-6C), R5 is H or linear, branched or cyclic alkyl, and R′ represents a cation, H or a substituted or unsubstituted alkyl group of 1-6C, promote bone formation and are thus useful in treating osteoporosis, bone fracture or deficiency, primary or secondary hyperparathyroidism, periodontal disease or defect, metastatic bone disease, osteolytic bone disease, post-plastic surgery, post-prosthetic joint surgery, and post-dental implantation. Also disclosed is a method to identify additional compounds which are inhibitors of enzymes in the isoprenoid scheme especially of HMG-CoA reductase which results in prenylation of proteins and in the synthesis of steroids or of inhibitors of their production which are useful in treating bone disorders.
摘要:
Compounds containing two aromatic systems covalently linked through a linker containing one or more atoms, or “linker” defined as including a covalent bond per se so as to space the aromatic systems at a distance 1.5-15 Å, are effective in treating conditions associated with bone deficits. The compounds can be administered to vertebrate subjects alone or in combination with additional agents that promote bone growth or that inhibit bone resorption. They can be screened for activity prior to administration by assessing their ability to effect the transcription of a reporter gene coupled to a promoter associated with a bone morphogenetic protein and/or their ability to stimulate calvarial growth in model animal systems.
摘要:
A therapeutically effective amount of an antibody for a compound selected from the group consisting of PTHrp, TGFα, IL-1α, IL-1β, IL-6, Lymphotoxin, TNF, PGE; 1,25 dihydroxy vitamin D3 and an antigenic fragment thereof used in the treatment of cancer metastasis to bone and cancer cell growth in bone as well as osteolysis and symptomatic sequelae thereof. An antibody immunoreactive with parathyroid hormone-related protein (PTHrp) is particularly preferred. Antibodies with human characteristics are included in the invention for application of the invention method to human subjects. Also, the antibody can be administered in an injectable is formulation in combination with a therapeutically effective amount of a bisphosphonate or pyrophosphate having the general structure formula wherein X is a linking moiety allowing for the interconnection of the phosphonate groups, and pharmaceutically acceptable salts, hydrates and partial hydrates thereof. The antibody and bisphosphonate act synergistically in the treatment of cancer metastases to bone and symptomatic sequelae thereof and particularly as regards bone resorption.
