A membrane-modifying peptide antibiotic, trichosporin B-VIa, having catecholamine secretion-inducing activity on bovine adrenal chromaffin cells has been synthesized. Aib14-Trichosporin B-VIa, in which Pro14 was replaced by Aib, has also been synthesized to modify the secondary structure of trichosporin B-VIa. Sequience-specific 1H-NMR assignments of both peptides in methanol were achieved by using two-dimensional NMR techniques.
我们合成了一种膜修饰肽抗生素--三碳卟啉 B-VIa,它对牛肾上腺绒毛细胞具有儿茶酚胺分泌诱导活性。此外,还合成了 Aib14-Trichosporin B-VIa,其中的 Pro14 被 Aib 取代,从而改变了三叶鞘磷脂 B-VIa 的二级结构。利用二维核磁共振技术实现了这两种肽在甲醇中的序列特异性 1H-NMR 分配。
