PEG是經環氧乙烷聚合而成的，相對分子量在200～8000或者8000以上的乙二醇高聚物，其由重復的氧乙烯基組成，不僅具有良好的水溶性，也能溶于DCM、DMF、苯、乙腈和乙醇等有機溶劑。PEG有2個末端羥基，具有線性的(相對分子質量為5000～30000)或支化的(相對分子質量為40000～60000)鏈狀結構，線性PEG的分子式為H-(O-CH2-CH2)n-OH。常用的PEG有PEG200、PEG300、PEG400、PEG600、PEG1000、PEG2000、PEG4000、PEG6000、PEG10000等，室溫下相對分子量為200～600的PEG是液體，相對分子量為1000及以上者是固體。

2、PEG在制劑方面的使用

PEG作為藥用輔料至今，已有上百年的歷史。由于PEG毒性小，水溶性好，長期以來倍受廣大藥劑工作者的青睞，廣泛的被應用于注射劑、局部用制劑、眼用制劑、口服及直腸用制劑等多種藥物劑型。PEG在水中具有較好的溶解性和良好的與藥物及其他溶劑的相溶性，相對分子質量小的液體PEG可以在制劑中作為溶劑使用，相對分子力量大的固體PEG可以與難溶性藥物制成固體分散體，以促進藥物的溶出。

PEG200、PEG300、PEG400、PEG600系無色、略有微臭的粘性液體，化學性質穩定，安全低毒，故常作為藥物的溶劑。而PEG4000、PEG6000主要是片劑中水溶性潤滑劑的典型代表，利用PEG制得片劑的崩解和溶出不受影響，可提高主藥在胃內的溶解性，zui終有助于增加生物利用度。除了可用作潤滑劑，PEG還可作為粘合劑，其中以PEG4000zui為常用，尤其是對于熱不穩定藥物，若采用PEG4000為粘合劑，可在干燥狀態下進行粉末直接壓片，效果較為理想。

除此之外，PEG還可作為增塑劑以改變聚合物的物理機械性質，使其更具柔順性、可塑性；作為膜控型緩控釋藥物的致孔劑；作為滲透促進劑使角蛋白溶劑化，占據蛋白質的氫鍵結合部位，減少藥物與組織間結合，增加并用的其他滲透促進劑在角質層的分配等。

3、PEG在合成方面的使用

PEG在化學合成方面的應用也有相當長的歷史，在組合化學和有機化學中得到了廣泛的應用，它可以提供均相反應條件，并具有便于純化和容易分析的優點，因此PEG作為溶劑、催化劑越來越多地應用于實驗室研究和工業化生產中。

作為溶劑，近年來的研究傾向于PEG的“綠色”，憑借其在室溫和高溫條件下的粘性、低毒性、熱穩定性、價格低廉、無揮發、可生物降解、對環境友好等特點，其在合成化學和非均相催化方面得到了越來越多的關注，如Heck反應、Suzuki偶聯反應、氧化反應、還原反應、加成反應和不對稱aldo反應等。且PEG在不同的溫度下有不同的溶解度，可以與水、二氯甲烷、醇、丙酮等溶劑互溶。但是PEG不溶于乙醚、正己烷等溶劑，所以可以用來沉淀PEG，從而可以使PEG和溶質得到分離。目前，已經有大量文章報道了PEG是可以重復使用的溶劑。

而在催化方面，由于PEG的鏈狀結構可折疊成不同大小的空穴，鏈節可以折疊成螺旋狀并自由滑動的鏈，形成類似冠醚的形狀，因而它能與不同大小的金屬離子絡合而進行相轉移催化反應。在液-液相中反應效果雖不佳，但對鈉、鉀等金屬鹽所參與的反應有良好的催化作用。對于不同鹽類參與的反應，PEG400-1000是常用的催化劑，研究表明，PEG400，由于其分子量適中，尤其是兩個極性末端羥基的相對比例高，更適合于催化Na+、K+的鹽參與的反應；由于水溶性較強，通常在反應完成后用水即可洗去催化劑和鹽類副產物，使產物的處理過程大大簡化。用PEG400作為相轉移催化劑，由于其容易獲得，價格便宜，沒有冠醚樣的毒性問題，也沒有季銨鹽的分解問題，已被人們廣泛地應用于許多液-液、氣-液、氣-固、固-液兩相有機化學反應當中。尤其是在無溶劑條件下的固-液反應，PEG400顯現了其它PTC所不能比擬的*性。

4、PEG與藥物分子的連接

20世紀70年代，Davis等報道用PEG修飾蛋白質，之后相繼開展了許多PEG與蛋白質和小分子藥物共價結合的研究。藥物的PEG修飾即PEG化，是將活化的PEG通過化學方法偶聯到蛋白、多肽、小分子有機藥物和脂質體上。藥物的PEG修飾可分為兩個階段。*階段的修飾技術局限于應用相對分子質量低的單甲氧基PEG (<20000)。常用的修飾劑有單甲氧基聚乙二醇琥珀酸琥珀酰亞胺酯、單甲氧基聚乙二醇碳酸琥珀酰亞胺酯等，通過酯鍵或三嗪環將PEG與藥物分子偶聯，這種非特異性的不穩定連接方式使得一個藥物分子經常連接數個PEG分子。如單甲氧基聚乙二醇琥珀酸琥珀酰亞胺酯偶聯到Lys殘基側鏈的ε-氨基上，由于蛋白質分子表面一般存在多個Lys殘基，加之每個ε-氨基的反應活性不同，修飾產物往往是不同修飾程度及不同修飾位點產物的混合物，這些混合物一般難以分開，不易分離。因此，第1代PEG修飾藥物通常表現出不穩定性、較大的毒性和免疫原性，生物活性、藥代動力學的性質與原型藥物沒有本質的改變。

以應用相對分子質量高(>20000) PEG修飾劑為特征的第二階段的修飾技術具有連接穩定、定點修飾、控釋等特點。因此，修飾后的藥物具有更高的生物活性、更好的物理及熱穩定性、更高的產品均一性和純度。這一階段PEG修飾技術不僅成功應用于蛋白質、多肽藥物的研究，在有機小分子藥物和脂質體研究領域內也取得了突破性進展。

PEG與藥物分子的連接方式大致分為*鍵合和非*鍵合。前者是PEG通過化學鍵與藥物分子穩定結合，且藥物分子仍能有效發揮藥效；后者是PEG通過化學鍵與藥物分子間形成不穩定的結合，該類復合物往往需要在一定的pH值或某些特定酶存在的條件下，水解釋放出游離藥物后才能有效發揮藥效。小分子藥物一般較少與PEG直接相連，而是通過各類連接臂相連。選擇適當的連接臂種類還可達到緩慢釋放、靶向釋放及增大載藥量等目的。通常，連接臂種類主要有4類，pH敏感型連接臂、酶敏感型連接臂、鄰位促進型連接臂以及N-曼尼希堿型連接臂。

修飾的藥物與未修飾的藥物相比，往往具有以下突出的優點：(1)更強的生物活性；(2)脂質體對腫瘤有更強的被動靶向作用；(3)更長的半衰期；(4)較低的zui大血藥濃度；(5)血藥濃度波動較小；(6)較少的酶降解作用；(7)較少的免疫原性及抗原性；(8)較小的毒性；(9)更好的溶解性；(10)用藥頻率減少；(11)提高病人的依從性，提高生活質量，降低治療費用。

5、PEG修飾的相關技術關鍵點

PEG的相對分子量選擇
分子量的選擇要綜合考慮生物活性和藥代動力學兩方面的因素。已有研究證明，修飾的蛋白藥物在體內的作用時間與偶聯的PEG數量和相對分子量成正比，在體外的生物活性與偶聯的PEG數量和相對分子量成反比，修飾時具體PEG分子量的選擇要根據實驗確定，一般選擇分子量在40000～60000范圍內的PEG作為修飾劑。

修飾位點的選擇
蛋白質PEG修飾時要根據蛋白質構效關系的分析選擇不與受體結合的蛋白質表面殘基作為修飾位點，這樣修飾后的蛋白質能夠保留較高的生物活性。有機小分子藥物的修飾位點與生物活性無關。理想的PEG修飾技術是根據要修飾的位點選擇適當的PEG得到均一性的產品。

其它化學因素
(1)修飾反應的pH值；(2)藥物與PEG的摩爾比；(3)藥物濃度；(4)反應時間；(5)反應溫度。PEG修飾反應需要高度的特異性和溫和的反應條件，可以控制其中的一個或幾個影響因素，得到高產率的目標修飾藥物。
