By means of successive actions of α-chymotrypsin and papain, tryptophane analogue of Leu-enkephalin (Tyr-Gly-Gly-Trp-Leu-NH_2) was synthesized by stepwise elongation from C-terminal, leucylamide, towards the N-terminal. The choice of appropriate enzyme and solvents was studied. The N-blocked amino acid ester serves as a better donor than the corresponding free acid in the peptide formation, irrespective of whether α-chymotrypsin or papain was used, but thermolysin, on the other hand, needs N-blocked amino acid...

By means of successive actions of α-chymotrypsin and papain, tryptophane analogue of Leu-enkephalin (Tyr-Gly-Gly-Trp-Leu-NH_2) was synthesized by stepwise elongation from C-terminal, leucylamide, towards the N-terminal. The choice of appropriate enzyme and solvents was studied. The N-blocked amino acid ester serves as a better donor than the corresponding free acid in the peptide formation, irrespective of whether α-chymotrypsin or papain was used, but thermolysin, on the other hand, needs N-blocked amino acid as a doncr. In the last step of pentapeptide synthesis catalyzed by α-chymotrypsin, the phase transfer method seems preferable to the ordinary solution method. The tryptophane analogue of Leu-enkephalin has also been synthesized by chemical method. The results also show some advantages of the use of immobilized enzyme.

在先后以α-胰凝乳蛋白酶和木瓜酶作催化剂的作用下,从C端的LeuNH_2的氨基开始,逐个与N保护的氨基酸或其衍生物缩合,合成了亮-脑啡肽色氨酸类似物—TyrGlyGly Trp LeuNH_2~(**)。对酶的专一性、有机溶剂的选择和合成条件等进行了研究,在Z-TyrOMe和GlyGlyTrp LeuNH_2的缩合反应中,比较了相转移法和均相法。上述两种酶的酶促接肽的供体以N-酰基氨基酸酯为好,比相应的游离酸反应速度快,副反应少。如用嗜热菌蛋白酶,则以N-酰基氨基酸为好。酶促合成与从有机合成所得的产物相同。初步的体外实验表明合成的TyrGlyGlyTrpLeuNH_2和天然的亮-脑啡肽对豚鼠回肠的收缩显示相同程度的鸦片样的抑制作用。
