N-(2,4-Dinitrophenyl)tetrapeptide p-nitroanilides related to the β-turn part of gramicidin S were synthesized and subjected to CD measurements. The β-turn preference of the tetrapeptide derivatives had correlation with the antibiotic activities of the gramicidin S analogs containing similar tetrapeptide sequences at their β-turn part. So, conformational preference of partial sequences of gramicidin
合成了与短杆菌肽 S 的 β-转角部分相关的 N-(2,4-二硝基苯基) 四肽对硝基苯胺,并进行 CD 测量。四肽衍生物的β-转角偏好与在其β-转角部分含有相似四肽序列的短杆菌肽S类似物的抗生素活性相关。因此,短杆菌肽 S 类似物部分序列的构象偏好似乎对确定其生物活性起着重要作用。
