Osteoclastogenesis inhibitors and uses thereof
The present invention provides a method of reducing or inhibiting osteoclast development induced by the receptor for activation of nuclear factor kappa B ligand (RANKL), comprising the step of contacting said osteoclast, or a precursor of the osteoclast, with a pharmacologically effective dose of compounds such as diferuloylmethane, guggulsterone, 1′-Acetoxychavicol or analogues thereof.
1. A method of inhibiting the formation of osteoclasts in an individual, comprising identifying an individual in need of an inhibitor of the formation of osteoclasts and administering to said individual a pharmacologically effective dose of diferuloylmethane, guggulsterone, 1′-Acetoxychavicol or an analogue thereof, wherein the individual has multiple myeloma, breast cancer, rheumatoid arthritis, or Paget's disease and the formation of osteoclasts is inhibited.
2. The method of claim 1 , wherein RANKL-mediated NF-κB activation in said individual is inhibited.
3. The method of claim 2 , wherein said inhibition of RANKL-mediated NF-κB activation is by inhibition of IκB kinase activity.
4. The method of claim 1 , wherein said individual is administered diferuloylmethane in a concentration of from about 0.01 mg/kg of said individual's body weight to about 100 mg/kg of said individual's body weight.
5. The method of claim 1 , wherein said individual is administered guggulsterone in a concentration of from about 0.01 mg/kg of said individual's body weight to about 100 mg/kg of said individual's body weight.
6. The method of claim 1 , wherein said individual is administered 1′-Acetoxychavicol in a concentration of from about 0.01 mg/kg of said individual's body weight to about 100 mg/kg of said individual's body weight.
7. A method of reducing osteolytic activity and bone loss in an individual, comprising identifying an individual in need of reduction of osteolytic activity and bone loss and administering to said individual a pharmacologically effective dose of diferuloylmethane, guggulsterone, 1′-Acetoxychavicol or an analogue thereof, wherein the individual has multiple myeloma, breast cancer, rheumatoid arthritis, or Paget's disease and osteolytic activity and bone loss in the individual is reduced.
8. The method of claim 7 , wherein said individual is administered diferuloylmethane in a concentration of from about 0.01 mg/kg of said individual's body weight to about 100 mg/kg of said individual's body weight.
9. The method of claim 7 , wherein said individual is administered guggulsterone in a concentration of from about 0.01 mg/kg of said individual's body weight to about 100 mg/kg of said individual's body weight.
10. The method of claim 7 , wherein said individual is administered 1′-Acetoxychavicol in a concentration of from about 0.01 mg/kg of said individual's body weight to about 100 mg/kg of said individual's body weight.
11. The method of claim 1 , wherein the individual has multiple myeloma.
12. The method of claim 1 , wherein the individual has Paget's disease.
13. The method of claim 1 , wherein the individual is administered a pharmacologically effective dose of diferuloylmethane.
14. The method of claim 7 , wherein the individual has multiple myeloma.
15. The method of claim 7 , wherein the individual has Paget's disease.
16. The method of claim 7 , wherein the individual is administered a pharmacologically effective dose of diferuloylmethane.
