Abstract

1532181 Pentapeptides BECKMAN INSTRUMENTS Inc 21 Jan 1977 [2 Feb 1976 8 April 1976] 02435/77 Heading C3H A pentapeptide of the formula wherein X is Gly, Ala, D-Ala provided that, if Y is OH, X is Ala or D-Ala, may be prepared by anchoring the carboxyl group of L-methionine to a solid support, and sequential condensation of L-phenylalanine; glycine; an amino acid selected from glycine, D-alanine and L-alanine; and L-tyrosine, to produce a pentapeptide chain bonded to said support, wherein the amino acids are N- protected and the N-protective group is removed after each condensation, and wherein the L-tyrosine carries a protected hydroxyl group; and deprotecting and cleaving said polypeptide from said support. In the Examples, BHA resin is condensed with (N-deprotection after each condensation), (i) Boc-Met-OH, (ii) Boc-Phe-OH, (iii) Boc-Gly- OH, (iv) Boc-Gly-OH, Boc-Ala-OH or Boc-DAla-OH, (v) Boc-Tyr(OBrZ)-OH, and the pentapeptides are cleaved and deprotected to yield H-Tyr-X<SP>1</SP>-Gly-Phe-Met-NH 2 wherein X<SP>1</SP> is Gly, Ala, D-Ala. Medicinal compositions, preferably in the form of powders or solutions, comprise the pentapeptides in admixture with a pharmaceutically-acceptable carrier.
