  • 这种 PAR-4 激活肽导致 PAR-3 缺陷小鼠血小板的分泌和聚集。

    This PAR-4 activating peptide caused secretion and aggregation of PAR-3 deficient mouse platelets.

    (Ala1)-PAR-4(1-6)(小鼠)是一种用于化合物中研究PAR-4(前列腺凋亡反应4)在小鼠中的作用的肽。它被专门设计为模仿小鼠PAR-4的前六个氨基酸,并用于研究其在癌症和凋亡相关疾病等疾病中的功能和潜在治疗靶点。

    (Ala1)-PAR-4 (1-6) (mouse) is a peptide used in compound to study the role of PAR-4 (Prostate Apoptosis Response 4) in mice. It is specifically designed to mimic the first six amino acids of mouse PAR-4 and is utilized to investigate its function and potential therapeutic targets in diseases such as cancer and apoptosis-related disorders.

    H-Ala-Tyr-Pro-Gly-Lys-Phe-OH is a peptide that activates toll-like receptor 4 (TLR4). It is a potent inhibitor of the enzyme phospholipase A2 and has been shown to inhibit the production of proinflammatory cytokines, such as IL1β, IL6, IL8, and TNFα. This peptide also has anti-inflammatory effects on autoimmune diseases, such as rheumatoid arthritis. H-Ala-Tyr-Pro-Gly-Lys-Phe-OH has been shown to inhibit prostate cancer cell growth in vitro and in vivo. It appears to exert its action by interfering with the transcriptional process at the level of RNA polymerase II. The mechanism may involve inhibition of the activation of basic fibroblast cells or suppression of epidermal growth factor signaling. H-Ala-Tyr - Pro - Gly - Lys - Phe -

  • 多肽H2N-Ala-Tyr-Pro-Gly-Lys-Phe-COOH的合成步骤:

    1、合成CTC树脂:称取1.26g CTC Resin(如初始取代度约为1.02mmol/g)和1.54mmol Fmoc-Phe-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3.86mmol 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-Phe-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-Phe-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3.86mmol Fmoc-Lys(Boc)-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7.71mmol DIPEA,3.66mmol 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-Lys(Boc)-Phe-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

    H2N-Lys(Boc)-Phe-CTC Resin

    Fmoc-Gly-Lys(Boc)-Phe-CTC Resin

    H2N-Gly-Lys(Boc)-Phe-CTC Resin

    Fmoc-Pro-Gly-Lys(Boc)-Phe-CTC Resin

    H2N-Pro-Gly-Lys(Boc)-Phe-CTC Resin

    Fmoc-Tyr(tBu)-Pro-Gly-Lys(Boc)-Phe-CTC Resin

    H2N-Tyr(tBu)-Pro-Gly-Lys(Boc)-Phe-CTC Resin

    Fmoc-Ala-Tyr(tBu)-Pro-Gly-Lys(Boc)-Phe-CTC 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-Ala-Tyr(tBu)-Pro-Gly-Lys(Boc)-Phe-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-Ala-Tyr-Pro-Gly-Lys-Phe-COOH。结构图见产品结构图。

    切割液选择:1)TFA:H2O=95%:5%、TFA:H2O=97.5%:2.5%

    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:
