MeOSuc-Ala-Ala-Pro-Val-AMC

Using γ-Secretase Inhibitors to Distinguish the Generation of the Aβ Peptides Terminating at Val-40 and Ala-42

at amino acid Ala-42. Due to the tendency of the longer Aβ peptides to more readily form fibrils (7 ), these may accelerate Aβ deposition, which ultimately leads to more aggressive, early onset forms of Alzheimer’s disease (8 ). With the transgenic

环肽的合成方法

[hCys-（N-Me）Phe -Tyr-D-Trp-Lys-Val]的合成也是应用HBTU为缩合剂，反应路线如下： 2.3 Bop法 McMurray等以Cyclo（Asp-Asn-Glu-Tyr-Ala-Ala-Arg-Gln-D-Phe-Pro）（Tyr I+1）为研究对象，以便确定Tyr I+1的哪些位置对蛋白酪氨酸激酶的亲和性是必不可少的，以及哪些氨基酸对活性贡献最大，以Bop/HOBt为复合缩合剂，在1mmol/L浓度下，合成了一系列Tyr I+1类似物，并经磷酸化和亲和力实验，发现6位
