Title: Parathyroid hormone analogues substituted at AA 25, 26, 27, and use in osteoporosis treatment
Abstract:Analogues of bovine and human parathyroid hormone, wherein twenty-fifth, twenty-six and twenty-seventh positions of the natural hormone, Arg-Lys-Lys- each have been substituted with Ala, Asn, Asp, Cys, Gln, Glu, Gly, His, Ile, Leu, Met, Phe, Pro, Ser, Thr, Trp, Tyr or Val have been found to retain bone cell effect with minimal effects on blood pressure and smooth muscle, including cardiac muscle. It has further been found that this effect can be obtained by using a synthetic PTH containing only the first 34 amino acids of PTH, with substitution at the twenty-fifth, twenty-sixth and twenty-seventh amino acids as described.
