一、聚乙二醇修饰剂近年来，蛋白质多肽等生物大分子药物和天然产物药物分子被越来越多的应用于疾病治疗领域，极大地推动了医药事业的发展。然而，生物大分子在药用过程中的作用却由于其半衰期短、容易产生免疫原性抗原性、易被酶解、有一定药理毒性等问题被大大限制。为有效解决该问题，上海西宝生物科技有限公司（Seebio）联合国内外著名修饰性PEG企业共同研制开发了一系列聚乙二醇修饰剂，通过对药物分子进行聚乙二醇化学修饰来达到延长药效的目的。因为聚乙二醇链的空间阻碍作用使得被修饰蛋白对蛋白酶酶解的抵抗能力大为提高，同时被修饰分子的分子排阻体积明显增大，使得其肾脏过滤清除率降低显著。同时，聚乙二醇分子的结构特异性使得肝脏网状内皮系统对被修饰蛋白的识别摄取和清除能力有所降低，并且可以降低或者消除诱导产生中和抗体和与抗体结合的能力，使其难以被免疫系统识别和清除，以上这些作用使得聚乙二醇修饰后的药物分子具有了相对未修饰药物更为优良的药理药代性能。Seebio提供的聚乙二醇修饰剂的种类包括有：【修饰性PEG的修饰基团】：氨基（-Amine）-NH2，氨甲基-CH2-NH2，马来酰亚胺-Mal，羧基-COOH,巯基（-Thiol）-SH，丙醛-ALD，琥珀酰亚胺碳酸酯-SC，琥珀酰亚胺乙酸酯-SCM，琥珀酰亚胺丙酸酯-SPA，琥珀酰亚胺琥珀酸酯-SS，琥珀酰亚胺-NHS，二硫吡啶基-OPSS，丙酸基-CH2CH2COOH，醛基-CHO，正吡啶二硫基-S-S-Pyridine，巯酯基-VS，丙烯酸基-Acrylate，丙烯酸基-AC，叠氮基-Azide，生物素基-Biotin，环氧基-EP，荧光素基-Fluorescein，戊二酸基-GA，酰肼基-Hydrazide，炔基-Alkyne，对硝基苯碳酸酯基-NPC，异氰酸基-NCO，邻二硫吡啶基-OPSS，硅烷基-Silane，-SVA，BOC-，羧甲基-CM，Fmoc-NH-。相关产品介绍1、单官能团PEG系列（mPEG-R）R：-CH2NH2；-COOH；-CH2CH2COOH；-EPMAL；-SC；Biotin-PPMAL；-SPA；-OCOOPhNO2；-CHO；-VS；-S-S-Pyridine；-Thiol-CH(OEt)2；-SH；-SS；-SG；-SCM；-OTS；-ButyrALD；-ALD；-AC；-Alkyne；-Azide；-Epoxide；-Hydrazide；-NCO；-NPC；-OPSS；SG；-Silane；-VS2、异双官能团PEG系列（R1-PEG-R2）R1：H-；NH2-；COOH-；MAL-；ACLT-；Biotin-；Gluc-；Gala-；AC-；BOC-；NH-；DSPE-；Fluorescein-；OPSS-；Thiol-；ACRL-；FMOC-NH-；R2：-NH2；-CH2NH2；-CH2CH2CH2NH2；-COOH；-CH2CH2COOH；-CHO；-CH(OEt)2；-NHS；-MAL；SCM；-SC；-Biotin；-Acid；-CM；-SVA；-VA；-Silane；3、同双官能团PEG系列（R-PEG-R）R：NH2；CH2NH2；CH2CH2COOH；EP-MAL；PP-MAL；NHS；OPSS；AC；ALD；Azide；；EP；GA；Hydrazide；NPC；SH；ACRL；-ButyrALD；-Thiol；Tosylate；VA；4、多臂支链PEG系列（PEGn-R(n=2、3、4)）R：-TS；-NP；-GS2；-MAL（C2、C5）；-ALD；-PA；CA；-COO-NHS;-CH2CH2CH2-NHCO-(CH2)3-COO-NHS5、LysineBranchedPEGsX：-O-NHS;-NH-CH2CH2-CHO;-NH(CH2)2-NHCO-(CH2)-maleimide6、ForkedPEGsX：-CH2CH2-NHCO-(CH2)3-COO-NHS;-CH2CH2NH2;--CH2CH2-NHCO-(CH2)2-maleimide7、ReleasedPEGs(mPEG-(CH2)n-Y-linker-X)X：-TS；Y：-COO-C6H5-;-COO-C6H3(CH3)28、多臂PEG系列(PEG-X)n（n=3、4、6、8）X：-CO-CH2CH2-COO-NHS;-CO-CH2CH2CH2-COO-NHS;-CH2CH2CH2CH2-COO-NHS;-CH2CH2CH2NH2;-CH2CH2NH2;-CH2CH2SH;-(CH2)3-NHCO-CH2CH2-Maleimide;-COO-phenyl-NO29、共聚物系列A-b-PEGA：PS；PI；PAN；PCL；PMMA；PPO；PGLY；PECHmPEG-b-AA：PS；PI；PAN；PCL；PMMA；PPO；PGLY；PECHA-b-PEG-b-AA：PHB；PHB/V；PCL；PLAR1-(PEG-b-A)-R2A：PS；PI；PAN；PCL；PMMA；PPO；PGLY；PECHR1：Br；R2：OHR1-(A-b-PEG)-R2A：PHB；PHB/V；PCL；PLA；PPO；PGLY；PECHR1：Br；R2：OHR-(PEG-b-A-b-PEG)-RA：PPO；PGLY；PECHR：OH(PEG-b-A)-RA：PS；PIR：OHR-(PEG-b-A-b-PEG)A：PS；PIR：OHA-b-(PEG)2A：PS；PI【常见的定制合成系列功能团修饰性PEG衍生物】：1.mPEG(单甲氧基醚PEG)(monomethoxypoly(ethyleneglycol))或者mPEO(monomethoxypoly(ethyleneoxide))CH3O-(CH2CH2O)n-CH2CH2OH能够合成二醇含量很低的mPEG,其含量<5%，分子量分布在1.04~1.1之间。合成所需时间：约2周2.mPEG-NH2(mPEG-胺基)mPEG-amideCH3O-(CH2CH2O)n-CH2CH2-NH2CH3O-(CH2CH2O)n-CH2CH2CH2-NH2带有伯胺端基的mPEG是一种非常有用的功能化高分子。在mPEG上的胺端基，对于酰化试剂的活性比羟基高，因此，它们很容易进行还原氨基化反应。应用胺基的反应活性，我们可以很方便的通过生成稳定的化学键(如酰胺键，氨基甲酸酯键，脲键和仲胺键),把另一些分子和其连接。此化合物的纯度近似于90%。它们可用于：制备带有生物活性化合物的配体；多肽合成时的载体；制备高分子接枝物和PEG涂层；制备PEG糖蛋白配体；合成所需时间：约2个周3.mPEG-SS(mPEG-琥珀酰亚胺琥珀酸酯)(mPEG-succinimidylsuccinate)mPEG-SS是较早使用带活性基团的PEG，它的反应活性较高，但是由于和PEG主链连接的是酯键，因此，在强碱或强酸条件下，酯键易断裂水解，使活性基团的含量下降。该产品的含量>95%。合成所需时间：约2个周4.mPEG-SC(mPEG-琥珀酰亚胺碳酸酯)(mPEG-succinimidylcarbonate)mPEG-SC是目前最常用的带活性基团的PEG衍生物，它和蛋白偶合生成的氨基甲酸酯键比酯键要稳定，现广泛用于与药物的偶联反应中。其纯度>95%.合成所需时间：约2个周5.mPEG2-NHS(mPEG2-N-羟基琥珀酰亚胺酯)(mPEG2-N-hydroxysuccinimde)通过把mPEG偶联到赖氨酸上得到含有羧基的双臂mPEG2-COOH,然后再与NHS活化后得到双臂mPEG琥珀酰亚胺酯（mPEG2-NHS）。mPEG2-NHS具有许多优点，其产物的支化结构会产生较大的分子体积，这样它们就不大可能渗透到蛋白质空间位阻大的区域。在和蛋白偶联后，不需要太多的偶联点便可使偶联产物保留PEG所具有的特点。mPEG2试剂尽管其水解速率及与小分子的反应速率比大多数NHS活性酯快，但与蛋白质的反应速率却要慢一些。这是由于其较大的空间位阻的缘故，因此适当延长和蛋白质的反应时间是必要的。该产品的纯度>95%。合成所需时间：约2个月。俞小姐13817370083QQ：24576553046.mPEG-SPA(mPEG-琥珀酰亚胺丙酸酸酯)(mPEG-succinimidylpropionate)PEG羧酸的NHS活性酯是最常用来与蛋白质偶合的PEG衍生物。它能与蛋白质上的赖氨酸的胺端基反应生成稳定的酰胺键。mPEG-SPA主链中不含有酯键，因此稳定性较高，其在PH等于8的水溶液中的半衰期为16.5分钟，大大高于mPEG-SS的9.6分钟。mPEG-SPA的纯度约为95％。合成所需时间：约4个周7.mPEG-ALD(mPEG-丙醛)(mPEG-aldehyde)在硼氢化钠存在下，带醛基的PEG会和伯胺发生还原氨化反应。醛基和其它的亲电活性基团不同，它只和胺基反应。虽然醛基的反应活性比NHS活性酯低，但是它具有反应条件温和(pH6-9.5，6~24小时)，易于使PEG和蛋白质或其它材料的表面连接。因此，在较低的pH下，mPEG-ALD会对蛋白质的N端进行选择性反应。其连接的稳定性（通过还原反应形成仲胺）对于制备固定化酶是极其重要的。用这种方式改性的蛋白质，可以保留氨基和蛋白在溶剂中的带电性，这对于保持蛋白质的构造和活性是非常重要的。通过氨基酸分析方法对蛋白质水解物中的赖氨酸进行定量分析，可以很方便地对这些偶合产物进行表征。mPEG-ALD是蛋白质N端PEG化的通用试剂。其纯度大约为80%。8.mPEG-MAL(mPEG-马来酰亚胺)(mPEG-maleimide)马来酰亚胺和巯基的偶合是蛋白和多肽偶联中的一个非常有用的反应。这个反应很特别，即使在其它功能基存在下，它也可以在温和的条件下进行。作为有活性端基的聚合物，mPEG-MAL已被用来合成具有确定结构和生物活性的PEG-蛋白质偶合物。mPEG-MAL也常用作聚合物试剂来选择性诱捕含巯基的多肽。产物的纯度约为80%。合成所需时间：3周。俞小姐13817370083QQ：24576553049.HO-PEG-COOH(a-羟基-w-羧基聚乙二醇)(α-hydroxyl-PEG-ω-carboxyl)合成所需时间：2个月10.mPEG-b-PS(聚乙二醇和聚苯乙烯的嵌段共聚物)(mPEG-block-polystyrene)；合成所需时间：3周11.mPEG-b-PI(聚乙二醇和聚异戊二烯的嵌段共聚物)(mPEG-block-polyisoprene)；合成所需时间：3周12.mPEG-b-PAN(聚乙二醇和聚丙烯腈的嵌段共聚物)(mPEG-block-polyacrylonitrile)；合成所需时间：3周13.mPEG-b-PCL(聚乙二醇和聚ε-己内酯的嵌段共聚物)(mPEG-block-poly(ε-caprolactone))；合成所需时间：1周14.mPEG-b-PMMA(聚乙二醇和聚甲基丙烯酸甲酯的嵌段共聚物)(mPEG-block-poly(methylmethacrylate))；合成所需时间：3周15.PEG(双羟基PEG)HO-(CH2CH2O)n-CH2CH2OH(分子量分布<1.15)各种分子量均能提供；合成所需时间：约2周16.HO-PEG-NH2(α-羟基-ω-氨基聚乙二醇)(α-hydroxyl-PEG-ω-amide)；合成所需时间：约3个周17.mPEG-羧基（mPEG-carboxyl），各种分子量的产品，其纯度>95%。18.mPEG-腈基(mPEG-cyan)各种分子量的产品，其纯度>95%。19.mPEG3-COOH和mPEG3-NHS；合成所需时间：２个月。20.三臂PEG以及四臂PEG（端基均为羟基）各种分子量；合成所需时间：3个周。21.超支化的聚丙三醇hPG(hyperbranchedpoly(glycerol).各种分子量的超支化PG..合成所需时间：3个周。同时提供进口原装修饰性PEG：货号货号品
