Definitions
- the present invention relates to a peptide having osteoclast differentiation and activity inhibiting ability and use thereof.
- Bones support the soft tissues and weight of the body and surround internal organs to protect internal organs from external stratification. It is also an important part of the human body that not only structurally supports muscles or organs but also stores calcium and other essential minerals in the body, such as phosphorus and magnesium. Thus, the bones of grown adults do not stop, but until the day they die, the bones of the old ones are removed and replaced with new ones, creating and balancing the very dynamic and continuous regeneration process. This is called bone remodeling. Bone turnover, which removes old bones and replaces them with new ones, is essential to repair bone damage caused by growth and stress and to maintain proper bone function.
- Osteoblasts produce the RANKUreceptor act ivator of nuclear factor- ⁇ igand (OPG) and osteoprotegerin (OPG), its decoy receptor.
- OPG nuclear factor- ⁇ igand
- OPG osteoprotegerin
- osteoclasts from blood cells (hematopoietic stem cells), which puncture the bones and release a small amount of breast into the bloodstream to maintain body function.
- Osteoblasts produced from bone cells fill the pores with collagen and cover the calcium and phosphorus infiltrates (hydroxyapat i te) to rebuild the skeleton by making new bones. It takes about 100 days for bones to begin to break down and rebuild into new bones.
- Osteoporosis is a disease in which bone mass decreases due to various causes and the risk of fracture increases continuously due to the deterioration of the microstructure of bone tissue. Osteoporosis is a condition in which minerals (particularly calcium) and substrates that make up bone are reduced. Formation is broken and osteoclasts occur in an increased state than osteopathy. Normal bones have a dense structure like a net, but in the case of osteoporosis, the gap between the structures becomes wider and the microstructures become thinner and weaker, so that the bones can be easily fractured even in small strata.
- Osteoporosis is characterized by rapid bone loss at the onset of menopause (2-3% per year) and postmenopausal osteoporosis, a postmenopausal osteoporosis that increases the risk of spinal compression and crushing of the wrist.
- Seni le osteoporosis which causes progressive bone loss of the hip and vertebrae (0.5 to 13 ⁇ 4 per year), and age-related diseases (endocrine disease, gastrointestinal disease, malignancy)

- Bone damage caused by osteoporosis and bone metastasis of cancer cells includes Fosamax (component name: alendronate) and actonel (Actonel, Ingredients: Bi sphosphonate-based therapeutics such as ri sedronate are being used. Most of these bisphosphonate preparations work to slow or stop bone loss by weakening and inducing the death of osteoclasts that destroy bone. However, these drugs do not promote the formation of new bones, and in recent years patients taking bisphosphonates develop osteonecrosis, severe atrial fibrillation, incapacitation of bones or joints, or musculoskeletal pain. It is increasing.
