Abstract
Synthetic peptides are provided which are extremely potent in stimulating the release of pituitary GH in animals and which have the formula: H--R.sub.1 --Ala--Asp--Ala--Ile--Phe--Thr--R.sub.8 --Ser--R.sub.10 --Arg--R.sub.12 --R.sub.13 --Leu--R.sub.15 --Gln--Leu--R.sub.18 --Ala--Arg--Lys--Leu--Leu--R.sub.24 --R.sub.25 --Ile--R.sub.27 --R.sub.28 --Arg--Gln--Gln--Gly--Glu--R.sub.34 --Asn--Gln--Glu--R.sub.38 --R.sub.39 --R.sub.40 --Arg--R.sub.42 --R.sub.43 --Leu--Y wherein R.sub.1 is Tyr, Met, Leu, D--Tyr, D--His or His; R.sub.8 is Ser or Asn; R.sub.10 is Tyr or D--Tyr; R.sub.12 is Arg or Lys; R.sub.13 is Ile or Val; R.sub.15 is Gly or D--Ala; R.sub.18 is Tyr or Ser; R.sub.24 is His or Gln; R.sub.25 is Glu or Asp; R.sub.27 is Met, Ala, Nle, Ile, Leu or Val; R.sub.28 is Asn or Ser; R.sub.34 is Arg or Ser; R.sub.38 is Gln or Arg; R.sub.39 is Arg or Gly; R.sub.40 is Ser or Ala; R.sub.42 is Phe or Ala; R.sub.43 is Asn or Arg; and Y represents the carboxyl moiety of the amino acid residue at the C-terminus and is the radical --COOR,--CRO,--CONHNHR, --CON(R)(R') or --CH.sub.2 OR, with R and R' being lower alkyl, fluoro lower alkyl or hydrogen, or a fragment thereof extending from the N-terminus in a continuous sequence at least to the residue in position 29, which fragment is biologically active to cause the release of GH from the pituitary, or a nontoxic salt of such peptide or peptide fragment. The peptides are analogs of human GRF and contain at least two but less than all of the following residues: R.sub.8 is Asn, R.sub.12 is Lys, R.sub.13 is Val, R.sub.18 is Ser, R.sub.24 is Gln, R.sub.25 is Asp, R.sub.28 is Ser.
