These compounds exhibit significant activity in mobilization of bone, making them therapeutic agents for the treatment or prophylaxis of osteoporosis, osteomalacia, osteopenia, renal osteodystrophy and hypoparathyroidism.

Novel parathyroid hormone polypeptides and biologically active fragments thereof are disclosed along with nucleic acid molecules encoding same. In particular, parathyroid hormone polypeptides and biologically active fragments (and encoding nucleic acid molecules) derived from fish species (eg Japanese pufferfish (Fugu rubripes)) are disclosed. Such polypeptides and fragments may be used for treatment of diseases associated with abnormal calcium homeostasis (eg osteoporosis, osteopenia, Paget's disease, bone cancer, hyperparathyroidism, hypoparathyroidism, hypercalcemia, psoriasis and other skin-related conditions).

The present invention relates to calcifediol soft capsules, to their use in the treatment or prevention of diseases related to vitamin D deficiency, such as vitamin D deficiency, demineralization such as hypocalcemia and hypophosphatemia, renal osteodystrophy, rickets, osteoporosis, osteopenia, osteoarthritis, osteoarthrosis, osteomalacia, hypoparathyroidism, and inflammatory bowel disease, and to their process of manufacture.

Described are polypeptide analogs of parathyroid hormone (PTH) that include at least two non-adjacent β-amino acid residues in place of a naturally occurring α-amino acid residues. Also described are pharmaceutical compositions useful for treating hypoparathyroidism that contain the analogs and methods of using the analogs to treat hypoparathyroidism.

The invention discloses a ligustrum lucidum glucoside concentrate and an application thereof. A preparation method of the ligustrum lucidum glucoside concentrate has the following steps: adding 10-14times amount of ethanol having a volume concentration of 50-80% into ligustrum lucidum, performing reflux extraction for 1-3 h, filtering, adding 8 times amount of the ethanol having a volume concentration of 50-80% into medicine residues, performing reflux extraction for 1-3 h, filtering, combining two filtrates, recovering solvents, adding appropriate amount of ethyl acetate for extraction, discharging an ethyl acetate layer, adding water-saturated n-butanol into a water layer for extraction, combining a water-saturated n-butanol layer, condensing, and performing vacuum drying to prepare theligustrum lucidum glucoside concentrate. The invention also discloses an application of the ligustrum lucidum glucoside concentrate in preparation of medicine for treating hypoparathyroidism.

The invention provides a preparation method of a falecalcitriol controlled-release tablet, and belongs to the technical field of medicines. The falecalcitriol controlled-release preparation in the invention is composed of a tablet containing core and a coating film wrapping the tablet containing core; the tablet containing core comprises falecalcitriol, a filler and sodium chloride; the coating film comprises a controlled-release material, a plasticizer and a pore-foaming agent; when preparation, the tablet containing core is wrapped by the coating film, wherein the main component, namely falecalcitriol, belongs to the vitamin D3 analogue, can adjust calcium metabolism and resist rickets, and can be used for treating hypoparathyroidism. The drug in the invention can be released slowly anduniformly; the purposes of being long to act and increasing the curative effect are achieved; the dosage also can be reduced when the same drug effect is kept; therefore, side effects of taking drugsto patients are reduced; furthermore, the preparation process is simple; and the obtained product is steady in quality and suitable for large-scale production and application.
