Abstract
Analogs of CRF, which are based upon hCRF, oCRF and alpha-helical CRF, are disclosed that can be administered to achieve a substantial elevation of ACTH, .beta.-endorphin, .beta.-lipotropin, other products of the pro-opiomelanocortin gene and corticosterone levels. Analogs include those having the formula: Y-R.sub.1 -R.sub.2 -R.sub.3 -R.sub.4 -R.sub.5 -Ile-Ser-Leu-Asp-Leu-Thr-Phe-His-Leu-Leu-Arg-Glu-Val-Leu-R.sub.20 -R.sub.21 -R.sub.22 -R.sub.23 -R.sub.24 -R.sub.25 -Gln-Leu-Ala-Gln-Gln-Ala-R.sub.32 -Ser-Asn-Arg-Lys-Leu-R.sub.38 -R.sub.39 -Ile-R.sub.41 -NH.sub.2, wherein Y is an acyl group having 7 or fewer carbon atoms or hydrogen; R.sub.1 is Ser or desR.sub.1 ; R.sub.2 is Glu, Gln or desR.sub.2 ; R.sub.3 is Glu or desR.sub.3 ; R.sub.4 is Pro or desR.sub.4 ; R.sub.5 is Pro or desR.sub.5 ; R.sub.20 is Ala or Glu; R.sub.21 is Met or Nle; R.sub.22 is Ala or Thr; R.sub.23 is Arg or Lys; R.sub.24 is D-Ala or Ala; R.sub.25 is Glu or Asp; R.sub.32 is D-His or His; R.sub.38 is Met, Nle or Leu; R.sub.39 is Ala, Glu or Asp; R.sub.41 is Ile or Ala; provided however that at least one of R.sub.20 and R.sub.39 is Ala. One example is [Ala.sup.20 ]-oCRF. These analogs or their pharmaceutically acceptable salts, dispersed in an acceptable liquid or solid carrier, can be administered to humans.
