[Problem] To provide a compound which may be used in treating diseases in which a calcium sensing receptor (CaSR) is concerned, particularly hyperparathyroidism. [Means for Resolution] It was found that novel pyrrolidine derivatives which are characterized by the possession of aminomethyl group substituted with arylalkyl group or the like, or salts thereof, have excellent CaSR agonistic regulatory activity and also have excellent selectivity with CYP2D6 inhibitory activity having a possibility of causing drug interaction. Based on the above, these novel pyrrolidine derivatives are useful as therapeutic agents for treating diseases in which CaSR is concerned (hyperparathyroidism, renal osteodystrophy, hypercalcemia and the like).

Methods of delivering therapeutic agents by administering compositions including a bacterial collagen-binding polypeptide segment linked to the therapeutic agent to subjects in need of treatment with the therapeutic agent are provided. Methods of treating hyperparathyroidism, and hair loss using compositions comprising a collagen binding polypeptide and a PTH / PTHrP receptor agonist are provided. In addition, methods of reducing hair regrowth by administering a composition including a collagen binding polypeptide and a PTH / PTHrP receptor antagonist are provided.

Methods of delivering therapeutic agents by administering compositions including a bacterial collagen-binding polypeptide segment linked to the therapeutic agent to subjects in need of treatment with the therapeutic agent are provided. In these methods, the therapeutic agent is not a PTH / PTHrP receptor agonist or antagonist, basic fibroblast growth factor (bFGF) or epidermal growth factor (EGF). The bacterial collagen-binding polypeptide segment delivers the agent to sites of partially untwisted or under-twisted collagen. Methods of treating collagenopathies using a composition including a collagen-binding polypeptide and a PTH / PTHrP receptor agonist are also provided. In addition, methods of treating hyperparathyroidism, and hair loss using compositions comprising a collagen binding polypeptide and a PTH / PTHrP receptor agonist are provided. Finally, methods of reducing hair regrowth by administering a composition including a collagen binding polypeptide and a PTH / PTHrP receptor antagonist are provided.

To provide a compound which can be used for treating diseases in which a calcium sensing receptor (CaSR) participates, particularly hyperparathyroidism. It was found that a novel piperidine derivative which is characterized in that one of a 3-position and a 4-position is substituted with an aminomethyl group substituted with an arylalkyl group or the like and the other position is substituted with aryl, heteroaryl or the like, or a salt thereof, has an excellent CaSR agonistic regulatory action, and also has excellent selectivity with a CYP2D6 inhibitory action having a possibility of causing drug interaction. Based on the above, this novel piperidine derivative is useful as a therapeutic agent for diseases in which CaSR participates (hyperparathyroidism, renal osteodystrophy, hypercalcemia, and the like).

The invention provides methods for treating or preventing bone degenerative disorders. The disorders treated or prevented include, for example, osteopenia, osteomalacia, osteoporosis, osteomyeloma, osteodystrophy, Paget's disease, osteogenesis imperfecta, and bone degenerative disorders associated with chronic renal disease, hyperparathyroidism, and long-term use of corticosteroids. The disclosed therapeutic methods include administering to a mammal an inhibitor of GDF-9 or BMP-15 in an amount effective to: (1 ) treat or prevent a bone degenerative disorder; (2) slow bone deterioration; (3) restore lost bone; (4) stimulate new bone formation; and / or (5) maintain bone mass and / or bone quality. The invention also provides methods for administering a GDF-9 agonist or a BMP-15 agonist to treat a bone disorder characterized by increased bone density or mass.
