迄今为止，pTH (1-31) 酰胺似乎是最小的有效成骨 pTH 片段。该 pTH 片段的成骨活性似乎与其激活腺苷酸环化酶的能力有关。与 pTH 不同，该片段不会激活磷脂酶 C，因此副作用较少，可用于骨质疏松症治疗。

pTH (1-31) amide appears so far to be the smallest of the potently osteogenic pTH fragments. The osteogenic activity of this pTH fragment seems to be related to its ability to activate adenylyl cyclase. Unlike pTH, this fragment does not activate phospholipase C and should therefore have fewer side-effects and find application in the osteoporosis treatment.
This product which is available as a 0.5mg vial is amino acids 1-31 of the 84 amino acid parathyroid hormone (PTH) and can be used as an adenylate cyclase and bone growth stimulating peptide.\nPTH is a peptide hormone that is secreted from the parathyroid gland in the event of abnormal serum calcium levels and it ultimately regulates calcium and phosphate levels in the body. The PTH exerts its activity through binding to the G-protein coupled receptor type 1 PTH receptor, which activates adenylate cyclase or phospholipase C thus activating pathways involved in the mediation of bone resorption and bone formation. This product is suitable for life science applications.

多肽H2N-Ser-Val-Ser-Glu-Ile-Gln-Leu-Met-His-Asn-Leu-Gly-Lys-His-Leu-Asn-Ser-Met-Glu-Arg-Val-Glu-Trp-Leu-Arg-Lys-Lys-Leu-Gln-Asp-Val-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1.1g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0.99mmol Fmoc-Val-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1.98mmol DIPEA，0.94mmol 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-Val-Linker-MBHA 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

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