Claim:
A peptide consisting of an amino acid sequence of: N(H)(R′)—X′ Z′(CORE PEPTIDE) Z″ X″—CO—R″ in which: a) N(H)(R′) is the amino terminal, wherein R′ is acetyl or hydrogen; and CO—R″ is the carboxyl terminal, wherein R″ is NH 2 or OH; b) X′ is present or absent, and, if present, is an L-amino acid or a di- or tripeptide of D or L-amino acids selected from the group consisting of Y, W, and F, provided that no amino acid is selected more than once; c) X″ is present or absent, and if present, is an L-amino acid selected from the group of consisting of Y, W, F, I, L or a dipeptide of D or L-amino acids selected from the group consisting of L and I; d) Z′ and Z″ are amino acids that are linked to each other so that the peptide is a cyclic peptide; and e) the CORE PEPTIDE is selected from the group of peptides consisting of *-N-Q-+ *-N-Q-L-I-+ SEQ ID NO:7 *-N-Q-L-+ *-N-Q-L-I-K-+ SEQ ID NO:8 *-N-Q-I-+ *-N-Q-I-K-+ SEQ ID NO:9 *-S-N-+ *-S-N-Q-L-+ SEQ ID NO:10 *-S-N-Q-L-I-+ SEQ ID NO:11 *-S-N-Q-L-I-K-+ SEQ ID NO:12 *-S-N-Q-I-+ SEQ ID NO:13 *-S-N-Q-I-K-+ SEQ ID NO:14 *-N-S-N-+ *-N-S-N-Q-+ SEQ ID NO:15 *-N-S-N-Q-L-+ SEQ ID NO:16 *-N-S-N-Q-L-I-+ SEQ ID NO:17 *-N-S-N-Q-L-I-K-+ SEQ ID NO:18 *-N-S-N-Q-I-K-+ SEQ ID NO:4 *-N-S-N-Q-I-+ SEQ ID NO:1 *-K-N-S-N-+ SEQ ID NO:20 *-K-N-S-N-Q-+ SEQ ID NO:21 *-K-N-S-N-Q-L-+ SEQ ID NO:22 *-K-N-S-N-Q-L-I-+ SEQ ID NO:23 *-K-N-S-N-Q-L-I-K-+ SEQ ID NO:3 *-K-N-S-N-Q-I-+ SEQ ID NO:2 *-K-N-S-N-Q-I-K-+ SEQ ID NO:4 *-E-N-K-+ *-E-N-K-E-+ SEQ ID NO:24 *-E-N-K-E-A-+ SEQ ID NO:25 *-L-E-N-K-+ SEQ ID NO:26 *-L-E-N-K-E-+ SEQ ID NO:27 *-L-E-N-K-E-A-+ SEQ ID NO:28 *-K-L-E-N-K-+ SEQ ID NO:29 *-K-L-E-N-K-E-+ SEQ ID NO:30 *-K-L-E-N-K-E-A-+ SEQ ID NO:5 *-S-G-Q-+ *-S-G-Q-V-+ SEQ ID NO:31 *-S-G-Q-V-L-+ SEQ ID NO:32 *-D-S-G-Q-+ SEQ ID NO:33 *-D-S-G-Q-V-+ SEQ ID NO:34 *-D-S-G-Q-V-L-+ SEQ ID NO:35 *-S-D-S-G-Q-+ SEQ ID NO:36 *-S-D-S-G-Q-V-+ SEQ ID NO:37 *-S-D-S-G-Q-V-L-+ SEQ ID NO:38 *-L-S-D-S-G-Q-+ SEQ ID NO:39 *-L-S-D-S-G-Q-V-+ SEQ ID NO:40 and *-L-S-D-S-G-Q-V-L-+ SEQ ID NO:6, wherein * and + designate the amino and carboxyl termini, respectively, and the single letters designate L-amino acids according to the single letter code, or wherein * and + designate the carboxyl and amino termini, respectively and the single letters designate D-amino acids according to the single letter code.
