摘要： Analogs of SRIF which are selective for SSTR4 in contrast to the other cloned SRIF receptors are useful in determining tissue and cellular expression of the receptor SSTR4 and its biological role in regulating tumor growth. SRIF analog peptides, such as des-AA1,2,4,5,12,13[Ala7]-SRIF; des-AA1,2,4,5,12,13[Aph7]-SRIF, des-AA1,2,4,5,12,13[Aph7]Cbm-SRIF; des-AA1,2,4,5,12,13[Tyr2,Ala7]-Cbm-SRIF, and des-AA1,2,4,5,12,13[Tyr7,CβMe-L-2Nal8]-SRIF, and counterparts incorporating D-Cys3 and/or D-Trp8 and/or Ala11, bind with high affinity to the cloned human receptor SSTR4 and activate the receptor, but they do not bind with significant affinity to human SSTR1, SSTR2, SSTR3 or SSTR5. By incorporating an iodinated tyrosine in position-2 in these SSTR4-selective SRIF analogs, a labeled compound useful in drug-screening methods is provided. Alternatively, for use in therapy, cytotoxins or highly radioactive elements can be N-terminally coupled or complexed thereto.

摘要： Peptides which include unnatural amino acids and which either promote or inhibit the secretion of gonadotropins by the pituitary gland and inhibit the release of steroids by the gonads. Administration of an effective amount of such peptides that are GnRH antagonists prevents ovulation of female mammalian eggs and/or the release of steroids by the gonads and may be used to treat steroid-dependent tumors. The agonists can be used for control of reproduction processes, to treat precocious puberty, endometriosis, and the like. The peptides are analogs of the decapeptide GnRH wherein there is at least one residue of an unnatural amino acid in the 3-, 5-, 6- and/or 8-positions. Unnatural amino acids having the following formula are incorporated in a preferred group of synthesized peptides:

摘要： Mammalian melanin-concentrating hormone (MCH) is isolated from rat tissue, purified and characterized. These MCH peptides are useful for treating skin disorders, for suppressing the proliferation of skin tumor cells, such as melanomas in mammals, and for modulating the secretion of ACTH. Generally, peptides are provided which have the following formula: ##STR1## or which are naturally occurring homologs of the peptide with said formula. The peptides which are the naturally occurring MCH homologs of mammalian species other than rat can also be obtained using the materials disclosed, as demonstrated specifically with human MCH, which is found to have the same structure as rat MCH. Also disclosed are the amino acid sequences of, and the nucleotide sequences of the cDNAs which encode, the putative precursors of rat MCH and human MCH. These precursors may also include one or more biologically active peptides N-terminally of the mature MCH's. Among these peptides, which are thought to be formed from the MCH precursors, are the peptide with the sequence H-Glu-Ile-Gly-Asp-Glu-Glu-Asn-Ser-Ala-Lys-Phe-Pro-Ile-NH.sub.2, which is cross-reactive with antibodies against alpha-MSH and CRF, and the peptide with the sequence H-Gly-X.sub.NGE -Phe-Pro-Ala-Glu-Asn-Gly-Val-Gln-Asn-Thr-Glu-Ser-Thr-Gln-Glu-OH, wherein X.sub.NGE is Pro-Ala-Val or Ser-Val-Ala, which is cross-reactive with antibodies against GRF.
