  摘要：

  已经合成了含有D-苯丙氨酸和D-色氨酸残基的环肽，并测试了其作为人肾素的抑制剂。其中大多数是CO（CH2）3CO-D-Phe-Lys-D-Trp-型或COCH2NHCH2CO-Dhe-Lys-D-Trp-型的三肽衍生物，其中各个侧链亚甲基已被取代-CHMe-，-CMe2-，-CH（Ph）-，-CH（CH2Ph）-或-CH [CH2）2CHMe2）-基团。这三个氨基酸残基和环的大小是这些化合物非常重要的特征。减小环的大小得到的有效化合物少得多。该系列最有效的类似物CO（CH2）2CHPhCO-D-Phe-Lys-D-Trp-NH（CH2）2CHMe（14，IC50 = 26 nM）通过取代更靠近D-的亚甲基获得-CHPh-基团的Phe残基。化合物14在抑制人肾素方面的效力比猪肾素高15倍。

  Continuing studies on modifications of potent cyclic pentapeptide endothelin (ET) receptor antagonists, represented by BQ-123, and potent linear tripeptide derivative ET receptor antagonists, represented by BQ-788, are described herein. The introduction of D-tryptophan analogues with C-2 substituents in these peptidic ET antagonists resulted in potent ET receptor antagonists with various ETA/ETB subtype selectivity

  本文描述了以BQ-123为代表的有效环状五肽内皮素（ET）受体拮抗剂和以BQ-788为代表的有效线性三肽衍生物ET受体拮抗剂的修饰的持续研究。在这些肽类ET拮抗剂中引入具有C-2取代基的D-色氨酸类似物，可产生具有各种ETA / ETB亚型选择性的有效ET受体拮抗剂。在环状五肽和线性三肽系列中都发现带有2-卤代和2-甲基-D-色氨酸的联合ETA / ETB受体拮抗剂。相反，具有2-氰基-D-色氨酸的化合物是ETB受体选择性拮抗剂。D-色氨酸残基的C-2取代基似乎对于区分拮抗剂的ETA / ETB亚型选择性非常重要。

  The preparation of a series of N-hydroxy peptides is described, along with their acylation on the oxygen of the pseudopeptide bond. Nineteen N-acyloxy peptides, first examples of this new class of pseudopeptides, were thus synthesized; they present a range of acyl groups, including N-protected amino acyl groups. Possibilities of elongation for these pseudopeptides were also investigated.

  cytarabine. In acute toxicity assay Trp-Trp-AA-OBzls did not damage the immunologic function and had an LD50 of more than 500 mg/kg. The relationships of structure and activity were analyzed with 3D QSAR. The action mechanism studies revealed that the in vivo anti-tumor action of Trp-Trp-AA-OBzls was the result of DNA intercalation.
