Method of correcting imbalance between bone resorption and bone formation and kits and compositions therefor
Compounds, methods, uses, compositions, kits and packages for the treatment of imbalance between bone resorption and bone formation, based on uses of 4-phenyl-2 propionamidotetralin (4-P-PDOT) and analogs, derivatives, prodrugs, precursors thereof, and salts thereof, are described.
1. A method comprising: (a) identifying a subject suffering from imbalance between bone resorption and bone formation; and (b) administering to said subject a therapeutically effective amount of (i) 4-phenyl-2-propionamidotetralin (4-P-PDOT); (ii) a conjugate of 4-P-PDOT; (iii) a pharmaceutical acceptable salt of (i) or (ii); or (iv) any combination of (i) to (iii), whereby imbalance between bone resorption and bone formation is improved in said subject.
2. The method of claim 1 , wherein the subject suffers from osteoporosis.
3. The method of claim 1 , wherein the subject suffers from Paget disease.
4. The method of claim 1 , wherein the subject suffers from osteolytic bone cancer.
5. The method of claim 1 , wherein the subject suffers from arthritis characterised by the presence of an inflammatory cytokine that induces osteoclasts.
6. The method of claim 1 , wherein said administration is a single bolus administration.
7. The method of claim 1 , wherein said administration is a daily administration.
8. The method of claim 1 , wherein said therapeutically effective amount is between 0.001 and 500 mg/kg of subject/day.
9. The method of claim 1 , wherein said improvement of imbalance between bone resorption and bone formation comprises at least one of: an inhibition of bone resorption; an inhibition of osteoclast differentiation; an increase in bone mineral density (BMD); an increase in bone mineral content (BMC); an increase of density of pure cortical bone; an increase of mean density of total bone; an increase of cortical thickness; an increase of pure cortical area assigned to be cortical; an increase of tibial diaphyseal total bone areas; an increase of mineralization apposition rate; an increase of bone formation rate/bone surface referent; an increase of mineralizing surface for endocortical or periosteal surface; a decrease of serum alkaline phosphatase; a decrease of intra-cortical regions of hypo-mineralized osteoid; a decrease of osteoid thickness and a decrease of osteoid condensation.
10. The method of claim 1 , wherein said correction of imbalance between bone resorption and bone formation comprises an inhibition of bone resorption.
11. The method of claim 1 , wherein said correction of imbalance between bone resorption and bone formation comprises an inhibition of osteoclast differentiation.
12. The method of claim 1 , wherein said correction of imbalance between bone resorption and bone formation comprises an increase in bone mineral density (BMD).
13. The method of claim 1 , wherein said correction of imbalance between bone resorption and bone formation comprises an increase in bone mineral content (BMC).
14. The method of claim 1 , which further comprises the administration of another agent selected from the group consisting of a bisphosphonate, raloxifene, nasal calcitonin and teriparatide.
15. The method of claim 1 , wherein the subject is a human.
