  摘要：

  合成了三十种脑啡肽的四肽酰肼类似物H-Tyr-D-Ala-Gly-Phe-NHN-(R1)-R2(R1, R2=H,烷基或酰基)。这些肽类经静脉或皮下注入小鼠后,测试其镇痛活性,并与吗啡进行比较,在合成的类似物中,四肽酰肼H-Tyr-D-Ala-Gly-Phe-NHNH-CO-R(R=低级烷基)活性最强,其镇痛活性比四肽酰胺H-Tyr-D-Ala-Gly-Phe-NH2强十倍,比吗啡弱一半。根据这些结果,讨论了新型脑啡肽类似物酰肼部分的构效关系。

  Peptidyl and azapeptidyl methylketones as substrate analog inhibitors of papain and cathepsin B

  摘要：

  Peptidyl methylketones containing Phe, Tyr, Tyr(I) Tyr(I-2), Leu and Ile in P-2 were synthesized and tested as substrate analog reversible inhibitors of papain and bovine spleen cathepsin B. The most effective cathepsin B inhibitor contained Tyr(I-2) and displayed an inhibition constant of 4.7 mu M at pH 6.8 and 25 degrees C, while Leu or lie gave practically inert analogs. Replacement of the amino acids in P-2 with the analogous alpha-azaamino acids, as well as the glycine in P-1 with alpha-azaglycine, led to complete loss of inhibiting activity. Introducing alkoxy substituents at the methyl adjacent to the ketone group generally resulted in more effective inhibitors, with inhibition constants in the micromolar range for both papain and cathepsin B.

  Thirty-five tetrapeptide acyl-hydrazide analogs of enkephalin substituted at position 2 were synthesized. Substitution of D-Ala at position 2 of H-Tyr-D-Ala-Gly-Phe-NHNH-CO-R (R=lower alkyl), by D-Met (O), D-Gln, D-Glu (NH-CH3) or D-Thr enhanced the analgesic potency, but substitution by D-Glu or Ser resulted in an analog with no antinociceptive activity. Among the analogs synthesized, the D-Met (O)-analog was the most potent and H-Tyr-D-Met (O)-Gly-Phe-NHNH-CO-CH2CH3 exhibited analgesic activtiy four times more potent than that of morphine in mice following subcutaneous injection. Structure-activity relations for position 2 of the enkephalin-like tetrapeptide are discussed.
