Gln15-motilin was synthesized in a conventional manner by assembling seven peptide fragments followed by deprotection with 1M trifluoromethanesulfonic acid-thioanisole in trifluoroacetic acid. The usefulness of phenylthiotrimethylsilane for the reduction of Met(O) was confirmed. This motilin analog was as biologically active as synthetic motilin in terms of contraction of rabbit duodenal muscles, but in radioimmunoassay it was only about 25% as reactive with antiserum raised against synthetic porcine motilin.

硅烷在还原Met(O)方面的有效性得到了证实。在兔十二指肠肌肉收缩方面,这种促胃肠蠕动素类似物与合成促胃肠蠕动素一样具有
生物活性,但在放射免疫测定中,它与针对合成猪促胃肠蠕动素产生的抗血清的反应性只有约25%。
