Synthesis of porcine motilin, which exhibits a gastric motor stimulating activity, was accomplished by the solid-phase method with diphenyl phosphorazidate (DPPA) and diethyl phosphorocyanidate (DEPC) as coupling reagents. The purified synthetic peptide showed characteristic contractile activity towards the duodenum, colon and jejunum in the rabbit. Its potency was almost the same as that of the natural material.
通过固相合成法,使用二苯基磷酰叠氮(DPPA)和二乙基磷酰氰(DEPC)作为偶联剂,成功合成了具有胃动力刺激活性的猪胃动素。纯化后的合成肽在兔子的十二指肠、结肠和空肠表现出特征性的收缩活性。其活性与天然物质几乎相同。
