    摘要: The invention relates to compounds of formula (I) or (II), which are of interest especially for inhibition of polymerization of amyloid null peptide, as model substances for synthesis of amyloid null peptide-ligands, as tools for the identification of other organic compounds with similar functional properties and/or as ligands for detection of amyloid deposits using e.g., positron emission tomography (PET). Formula (II) is: R1-Anull-Ynull-Leu-Xnull-Znull-Bnull-R2 in which Xnull means any group or amino acid imparting to the compound according to formula (I) the ability to bind to the KLVFF-sequence in amyloid null peptide, or two amino acids imparting the same ability, but with the proviso that one is not proline; Ynull means any amino acid; Znull means any non-acidic amino acid; Anull means a direct bond or an null-amino acid bonded at the carboxyl terminal of the null-carboxy group or a di-, tri-, tetra- or pentapeptide bonded at the carboxyl terminal of the null-carboxy group; Bnull means a direct bond or an null-amino acid bonded at the null-nitrogen or a di-, tri-, tetra- or pentapeptide bonded at the null-nitrogen of the N-terminal null-amino acid; R1 is H or nullCOnullR3 bonded at the null-amino group of Anull; R2 is H, nullOR4 or NR5R6, all bonded to the null-carboxyl group of the null-carboxyterminal of Bnull; R3 and R4 are straight or branched carbon chain of 1-4 carbon atoms; R5 and R6 are independently H, alkyl, cycloalkyl, aryl or substituted aryl or together are null(CH2)nnull where n is 4-5; and R1 and R2 together can form a hydrocarbon ring or heterocyclic ring; all null-amino acids being either D- or L-isomers.

    摘要: The invention provides ligands for melanocortin receptors. For example, the invention provides the melanocortin receptor peptide ligand Ac-Nlc-Gln-His-(p(I)-D-Phe)-Arg-(D-Trp)-Cly-NH2, (SEQ ID NO: 1), where the iodo group is unlabeled or radioactively labeled. The invention additionally provides methods of assaying for melanocortin receptors in a cell or tissue such as brain. The invention also relates to pharmaceutical compositions comprising a pharmaceutically acceptable carrier and a melanocortin receptor ligand and to methods of administering the pharmaceutical composition to a subject. The invention further provides tetrapeptide ligands for melanocortin receptors and methods of altering melanocortin receptor activity.
