    • The somatostatin-analogous peptides according to the invention of the general formula ##STR1## in which Bmp represents the desaminocysteine radicalX represents Asn or His,trp represents D-Trp that may be substituted in the benzene ring by a halogen atom, andY represents the radical of a secondary .alpha.-amino acid having a maximum of 8 carbon atomsand the corresponding peptide amides and also acid addition salts and complexes thereof are distinguished by strong insulin-antagonistic and glucagon-antagonistic effects and are therefore therapeutically acceptable, preferably in the form of pharmaceutical preparations, in similar indications to those of somatostatin, especially also as antidiabetics. The compounds are manufactured by conventional processes of peptide synthesis, especially by liberation from corresponding protected intermediates and by the formation of the cystine disulphide bridge by means of oxidation.

    • Sulphur-free cyclopeptides with somatostatin-analogous aminoacid partial sequences, of the formula ##STR1## in which R is Asn, Ala or de-R, trp is D-Trp or L-Trp, which can be substituted in the benzene ring by halogen atoms or nitro groups, W is a free or etherified hydroxyl group or halogen atom present as a substituent on the benzene ring of the L-phenylalanine radical, or is hydrogen, X is the radical of an .omega.-amino-lower alkane-(mono or di)-carboxylic acid or de-X and Y is the radical of an .omega.-amino-lower alkane-(mono or di)-carboxylic acid or de-Y, and also acid addition salts and complexes thereof have biological properties similar to those of somatostatin and can be used, especially in the form of pharmaceutical preparations, for the treatment of excessive secretion of somatotropin, insulin and/or glucagon. The compounds according to the invention are obtained by cyclising a corresponding linear peptide compound in which the .epsilon.-amino group of the lysine radical and, if desired, also the hydroxyl group of the threonine radical are protected and detaching the protective groups which are present.
    • 具有生长抑素 - 类似氨基酸部分序列的无硫环肽,其中R为Asn,Ala或de-R,trp为式(I),其为可在苯中取代的D-Trp或L-Trp 卤素原子或硝基,W是在L-苯丙氨酸基团的苯环上作为取代基存在的游离的或醚化的羟基或卤素原子,或是氢,X是ω-氨基 - 低级烷烃的基团 - (单或二) - 羧酸或脱-X,Y是ω-氨基 - 低级烷烃 - (单或二) - 羧酸或脱Y的基团,并且其酸加成盐和络合物具有生物 特性与生长抑素相似,可用于治疗生长激素,胰岛素和/或胰高血糖素过度分泌的药物制剂形式。 根据本发明的化合物是通过环化相应的线性肽化合物而获得的,其中赖氨酸基团的ε-氨基和如果需要也保护苏氨酸基团的羟基并分离存在的保护基团。
