    RGD肽-说明

    RGD肽是指含有由Arg-Gly-Asp三个氨基酸组成的序列多肽,有直线肽和环肽之分。它们是许多细胞外基质蛋白(如VN、FN、FGN、胶原等)等最小识别短肽序列。

    研究发现,RGD序列肽具有广泛的生物活性,可用于心血管疾病、骨质疏松和炎症等疾病的治疗,还可以预防和治疗由细胞粘附异常而导致的肿瘤,尤其是发展性肿瘤的转移;另一方面,RGD 序列肽又可作为兴奋剂,促进损伤的器官与组织的再生、伤口的愈合等等,RGD作为某些整合素的受体,其选择性部分依赖于RGD的构象以及RGD周围的氨基酸残基。

    为此,近几年,许多科技工作者合成了一系列RGD三肽、四肽、五肽等,还合成了RGD环肽、双线肽、RGD模拟肽等等。为了满足客户对各种RGD序列肽的需求,专肽生物提供最广泛的RGD序列肽库,以满足科研工作者对RGD肽的需求。

    专肽生物提供各种RGD肽的现货,缩短科研工作者的项目时间,例如c(RGDfK)c(RGDfC)c(RADyK)c(RGDyK)c(RADfC)环状多肽c(RGDfK)-巯基乙酸c(RGDfK)-PEG2-巯基乙酸Mpa-Ahx-c(RGDfK)环状多肽c(RGDfK)-半胱氨酸DOTA-c(RGDfK)NOTA-c(RGDfK)NOTA-c(RGDyK)DOTA-c(RGDyK)E[c(RGDfK)]2E[c(RGDyK)]2DDDDD-c(RGDfK)等等,具体可咨询销售人员。

  • 多肽H2N-Gly-Arg-Gly-Asp-Ser-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1.31g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1.18mmol Fmoc-Ser(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2.36mmol DIPEA,1.12mmol 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-Ser(tBu)-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

    H2N-Ser(tBu)-Linker-MBHA Resin

    Fmoc-Asp(OtBu)-Ser(tBu)-Linker-MBHA Resin

    H2N-Asp(OtBu)-Ser(tBu)-Linker-MBHA Resin

    Fmoc-Gly-Asp(OtBu)-Ser(tBu)-Linker-MBHA Resin

    H2N-Gly-Asp(OtBu)-Ser(tBu)-Linker-MBHA Resin

    Fmoc-Arg(Pbf)-Gly-Asp(OtBu)-Ser(tBu)-Linker-MBHA Resin

    H2N-Arg(Pbf)-Gly-Asp(OtBu)-Ser(tBu)-Linker-MBHA Resin

    Fmoc-Gly-Arg(Pbf)-Gly-Asp(OtBu)-Ser(tBu)-Linker-MBHA Resin

    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-Gly-Arg(Pbf)-Gly-Asp(OtBu)-Ser(tBu)-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-Gly-Arg-Gly-Asp-Ser-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。

    7、最后总结:
