多肽H2N-Thr-Leu-Asp-Leu-Ala-Ser-Val-Asp-Leu-Arg-Lys-Met-Arg-Val-Ala-Glu-Pro-Lys-Gln-Ile-Leu-His-Ser-Trp-Gly-Glu-Glu-Cys-Arg-Ala-Cys-Ala-Glu-Lys-Thr-Asp-Tyr-Val-Asn-Leu-Ile-Gln-Glu-Leu-Ala-Pro-Lys-Tyr-Ala-COOH的合成步骤：

1、合成CTC树脂：称取0.87g CTC Resin（如初始取代度约为1.15mmol/g）和1.2mmol Fmoc-Ala-OH于反应器中，加入适量DCM溶解氨基酸（需要注意，此时CTC树脂体积会增大好几倍，避免DCM溶液过少），再加入3.0mmol DIPEA（Mw：129.1,d：0.740g/ml），反应2-3小时后，可不抽滤溶液，直接加入1ml的HPLC级甲醇，封端半小时。依次用DMF洗涤2次，甲醇洗涤1次，DCM洗涤一次，甲醇洗涤一次，DCM洗涤一次，DMF洗涤2次（这里使用甲醇和DCM交替洗涤，是为了更好地去除其他溶质，有利于后续反应）。得到 Fmoc-Ala-CTC Resin。结构图如下：

2、脱Fmoc：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-Ala-CTC 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3.0mmol Fmoc-Tyr(tBu)-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6.0mmol DIPEA，2.85mmol 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-Tyr(tBu)-Ala-CTC Resin。氨基酸：DIPEA：HBTU：树脂=3：6：2.85：1（摩尔比）。结构图如下：

4、依次循环步骤二、步骤三，依次得到

以上中间结构，均可在专肽生物多肽计算器-多肽结构计算器中，一键画出。

最后再经过步骤二得到 H2N-Thr(tBu)-Leu-Asp(OtBu)-Leu-Ala-Ser(tBu)-Val-Asp(OtBu)-Leu-Arg(Pbf)-Lys(Boc)-Met-Arg(Pbf)-Val-Ala-Glu(OtBu)-Pro-Lys(Boc)-Gln(Trt)-Ile-Leu-His(Trt)-Ser(tBu)-Trp(Boc)-Gly-Glu(OtBu)-Glu(OtBu)-Cys(Trt)-Arg(Pbf)-Ala-Cys(Trt)-Ala-Glu(OtBu)-Lys(Boc)-Thr(tBu)-Asp(OtBu)-Tyr(tBu)-Val-Asn(Trt)-Leu-Ile-Gln(Trt)-Glu(OtBu)-Leu-Ala-Pro-Lys(Boc)-Tyr(tBu)-Ala-CTC 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-Thr-Leu-Asp-Leu-Ala-Ser-Val-Asp-Leu-Arg-Lys-Met-Arg-Val-Ala-Glu-Pro-Lys-Gln-Ile-Leu-His-Ser-Trp-Gly-Glu-Glu-Cys-Arg-Ala-Cys-Ala-Glu-Lys-Thr-Asp-Tyr-Val-Asn-Leu-Ile-Gln-Glu-Leu-Ala-Pro-Lys-Tyr-Ala-COOH。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。

7、最后总结：
