多肽H2N-Ala-Val-Ser-Glu-His-Gln-Leu-Leu-His-Asp-Lys-Gly-Lys-Ser-Ile-Gln-Asp-Leu-Arg-Arg-Arg-Glu-Leu-Leu-Glu-Lys-Leu-Leu-Aib-Lys-Leu-His-Thr-Ala-NH2的合成步骤:
1、合成MBHA树脂:取若干克的MBHA树脂(如初始取代度为0.5mmol/g)和1倍树脂摩尔量的Fmoc-Linker-OH加入到反应器中,加入DMF,搅拌使氨基酸完全溶解。再加入树脂2倍量的DIEPA,搅拌混合均匀。再加入树脂0.95倍量的HBTU,搅拌混合均匀。反应3-4小时后,用DMF洗涤3次。用2倍树脂体积的10%乙酸酐/DMF 进行封端30分钟。然后再用DMF洗涤3次,甲醇洗涤2次,DCM洗涤2次,再用甲醇洗涤2次。真空干燥12小时以上,得到干燥的树脂{Fmoc-Linker-MHBA Resin},测定取代度。这里测得取代度为 0.3mmol/g。结构如下图:
2、脱Fmoc:取1.81g的上述树脂,用DCM或DMF溶胀20分钟。用DMF洗涤2遍。加3倍树脂体积的20%Pip/DMF溶液,鼓氮气30分钟,然后2倍树脂体积的DMF 洗涤5次。得到 H2N-Linker-MBHA Resin 。(此步骤脱除Fmoc基团,茚三酮检测为蓝色,Pip为哌啶)。结构图如下:
3、缩合:取1.63mmol Fmoc-Ala-OH 氨基酸,加入到上述树脂里,加适当DMF溶解氨基酸,再依次加入3.26mmol DIPEA,1.55mmol HBTU。反应30分钟后,取小样洗涤,茚三酮检测为无色。用2倍树脂体积的DMF 洗涤3次树脂。(洗涤树脂,去掉残留溶剂,为下一步反应做准备)。得到Fmoc-Ala-Linker-MBHA Resin。氨基酸:DIPEA:HBTU:树脂=3:6:2.85:1(摩尔比)。结构图如下:

最后再经过步骤二得到 H2N-Ala-Val-Ser(tBu)-Glu(OtBu)-His(Trt)-Gln(Trt)-Leu-Leu-His(Trt)-Asp(OtBu)-Lys(Boc)-Gly-Lys(Boc)-Ser(tBu)-Ile-Gln(Trt)-Asp(OtBu)-Leu-Arg(Pbf)-Arg(Pbf)-Arg(Pbf)-Glu(OtBu)-Leu-Leu-Glu(OtBu)-Lys(Boc)-Leu-Leu-Aib-Lys(Boc)-Leu-His(Trt)-Thr(tBu)-Ala-Linker-MBHA Resin,结构如下:
5、切割:6倍树脂体积的切割液(或每1g树脂加8ml左右的切割液),摇床摇晃 2小时,过滤掉树脂,用冰无水乙醚沉淀滤液,并用冰无水乙醚洗涤沉淀物3次,最后将沉淀物放真空干燥釜中,常温干燥24小试,得到粗品H2N-Ala-Val-Ser-Glu-His-Gln-Leu-Leu-His-Asp-Lys-Gly-Lys-Ser-Ile-Gln-Asp-Leu-Arg-Arg-Arg-Glu-Leu-Leu-Glu-Lys-Leu-Leu-Aib-Lys-Leu-His-Thr-Ala-NH2。结构图见产品结构图。
切割液选择:1)TFA:H2O=95%:5%
2)TFA:H2O:TIS=95%:2.5%:2.5%
3)三氟乙酸:茴香硫醚:1,2-乙二硫醇:苯酚:水=87.5%:5%:2.5%:2.5%:2.5%
(前两种适合没有容易氧化的氨基酸,例如Trp、Cys、Met。第三种适合几乎所有的序列。)
6、纯化冻干:使用液相色谱纯化,收集目标峰液体,进行冻干,获得蓬松的粉末状固体多肽。不过这时要取小样复测下纯度 是否目标纯度。
