FIELD: chemistry.SUBSTANCE: invention relates to biotechnology, specifically PTH receptor agonists, and can be used in medicine. A polypeptide of formula PTH(1-X)/PTHrP(Y-36) is constructed, where denotes an integer between 11 and 18, and Y=X+1, where PTH(1-X) is an amino acid from 1 to X of the human PTH sequence (SEQ ID NO:5) and PTHrP(Y-36) is an amino acid from Y to 36 of the human PTHrP sequence (SEQ ID NO:6). The polypeptide contains one or more of the following mutations in the PTH(1-X) sequence: Ala in position 1, Ala or Aib in position 3, Gin in position 10, Arg or homoarginine in position 11, Ala in position 12, and Trp in position 14. The obtained polypeptide is used to repair fractures, treat hypoparathyroidism, hyperphosphatemia, tumoral calcinosis, osteoporosis, osteomalacia, arthritis, thrombocytopenia, as well as increase stem cell mobilisation in a subject.EFFECT: invention enables to obtain a polypeptide having prolonged activity on the PTH receptor.18 cl, 37 dwg, 8 tbl, 11 ex |
