Agonizing amylin analog, the analog intended for use as a medicament and pharmaceutical preparation in which this analog is comprised

摘要

(A) An agonist analogue of amylin having aminoacid sequence (I) is claimed. In (I) A1 is Lys, Ala, Ser or H; B1 is Ala, Ser or Thr; C1 is Val, Leu or Ile; D1 is His or Arg; E1 is Ser or Thr; F1 is Ser, Thr, Gla or Asn; G1 is Asn, Gln or His; H1 is Phe, Leu or Tyr; I1 is Ala or Pro; J1 is Ile, Val, Ala or Leu; K1 is Ser, Pro, Leu, Ile or Thr; L1 is Ser, Pro or Thr; M1 is Asn, Asp, Gln or Asn; X, Y are residues having side chains which are chemically bonded to each other to form an intramolecular linkage; and Z is amino, alkylamino, dialkylamino, cycloalkylamino, arylamino, aralkylamino, alkoxy, aryloxy or aralkyloxy, with provisos. The peptides are pref. prepd. by solid phase synthesis. Pref. peptides include 25,28,29 Pro-h-amylin (Ia), des-'Lys 25,28,29 Pro-h-amylia and 18 Arg 25,28 Pro-h-amylin.
