Abstract

Cyclic hexapeptides of the formula (I) and their salts are new. In (I), R1 is H or 1-4C alkyl; R3 is a natural or unnatural aminoacid radical with free or protected side chains or R3 is -(CH2)n-R" (where n is 1-5 and R" is cycloctyl, adamantyl, cyclohexyl or naphthyl, or additionally may be phenyl when n is other than 1, or additionally may be a substd. carboxamide gp. when n is 1 or 2); A1 is Gln or DGln; A2 is TrP or DTrp; A3 is Phe or DPhe; W is CONR1 or CH2NR1 (where R1 is H or CH3). The natural aminoacid is glycine, alanine, valine, leucine, isoleucine, proline, phenylalanine, tryptophan, methionine, serine, threonine, cysteine, tyrosine, asparagine, glutamine, aspartic acid, glutamic acid, lysine, arginine, or histidine, in L- or D-form. The unnatural aminoacid is beta-alanine, D or L 2-aminobutyric acid, D or L 2,3-diaminopropionic acid, D or L norleucine, D or L allosoleucine, D or L pyroglutamic acid, L or D 3-hydroxyproline, L or D 4-hydroxyproline, L or D phenylalanine substd. in the ortho, meta or para position, L or D thienylalanine, L or D pyridylalanine, beta (2- or 3-benzothienylalanine), or 1,2,3,4-tetrahydroisoquinolin -3-carboxylic acid. An aminoacid side chain protector is Mbs, Mtr, NO2, Z, Tos, Pmc, For, Me, Ac, 2-Br-Z, 2-Cl-Z, Bzl, 2,6-dichloro-Bzl, SO3H, Fmoc, OMe, OBzl, OFm, ONp or OSu.
