    • Cyclic octapeptides of the formula ##STR1## in which Aaa represents a radical of a straight-chained .alpha.,.omega.-diaminoalkanoic acid having from 4 to 7 carbon atoms,trp represents a radical L-Trp or, especially, D-Trp, or a radical derived therefrom, which carries a halogen atom in the indole nucleus,Ac.sub.A represents an acyl radical Ac of an optionally substituted carboxylic acid which is positioned at the .omega.-amino group, or represents an amidino group or hydrogen, andAc.sub.B represents an acyl radical Ac.sup.1 of an amino acid or of an oligopeptide which is positioned at the .epsilon.-amino group, or, preferably, represents hydrogen,as well as physiologically tolerable salts and therapeutically acceptable complexes thereof can be used as antidiabetics and for the treatment of gastro-intestinal bleeding in an analogous manner to somatostatin. They can be obtained by conventional processes of peptide chemistry, especially by the cyclization of corresponding linear peptides.

    • Somatostatin analogs are prepared wherein a cyclic hexapeptide contains a secondary amino acid which replaces seven of the ring amino acids of somatostatin. The cyclic hexapeptides are easier to synthesize, have a longer duration of activity, and many have a greater level of activity than somatostatin. The compounds have the properties of inhibiting the release of glucagon, growth hormone and insulin. Certain of the compounds also are capable of inhibiting the release of gastric acid secretions. The compounds are particularly useful in the treatment of acromegaly, diabetes, diabetic retinopathy and peptic ulcers. These cyclic hexapeptides are prepared by the solid phase method and/or solution synthesis.
    • 制备生长抑素类似物,其中环状六肽含有替代生长抑素的七个环氨基酸的仲氨基酸。 环状六肽更容易合成,具有较长的活性持续时间,并且许多具有比生长抑素更高的活性水平。 该化合物具有抑制胰高血糖素,生长激素和胰岛素释放的性质。 某些化合物还能够抑制胃酸分泌物的释放。 该化合物特别可用于治疗肢端肥大症,糖尿病,糖尿病性视网膜病变和消化性溃疡。 这些环状六肽通过固相法和/或溶液合成制备。
