In this study, three independent methods were used to identify short fragment of both chains of human insulin which are prone for aggregation. In addition, circular dichroism (CD) research was conducted to understand the progress of aggregation over time. The insulin fragments (deca- and pepta-peptides) were obtained by solid-phase synthesis using 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium
在这项研究中,使用了三种独立的方法来鉴定两条人胰岛素链中易于聚集的短片段。此外,还进行了圆二色性 (CD) 研究以了解聚合随时间的进展。胰岛素片段(十肽和肽肽)是通过固相合成获得的,使用 4-(4,6-二甲氧基-1,3,5-三嗪-2-基)-4-甲基吗啉鎓甲苯-4-磺酸盐( DMT/NMM/TosO-) 作为偶联剂。系统研究允许鉴定新的片段,预计在生理条件下参与触发人胰岛素整个结构的聚集。发现聚集过程通过各种结构构象异构体发生并且可能有利于聚集物的纤维结构的形成。
