探討生物正交反應及新型態PEGylated Group與螢光標記之結合

A Bioorthogonal Reaction with New PEGylated Group for Fluorescent Labelling Study

指導教授 : 林韋佑

摘要


生物正交反應,其在生物體內可進行具有選擇性及特異性之快速化學反應,不會干擾生物體反應。其在生物體中的水溶性與特異性之反應視為本實驗最重要的一環。 在本論文中,首先我們設計與合成了一系列的反式環辛烯的衍生物,並將其修飾於聚丙烯酸奈米氧化鐵的表面上,作為一生物正交反應基元。同時也合成1,2,4,5-四嗪的衍生物包含了水溶性聚乙二醇鏈段及綠色螢光物質,成為另一個生物正交反應基元。藉由質譜與核磁共振光譜等各種實驗證據,已證實兩者生物正交反應基元可以快速結合與鍵結。

Bioorthogonal reaction is a fast chemical reaction having good selectivity and specificity, covalent bond can be formed in a biological system without interfering any external chemical. Herein, we have developed a new chemical method in which grafted trans-cyclooctene (TCO) derivatives (a bioorthogonal reactive motif) into PAAIO in a aqueous solution, then followed by injection of tetrazine derivatives labeled with a green fluorescent dye as a chemical reporter. The [4+2] cycloaddition reaction between TCO and tetrazine is called as IEDDA. The solubility is increased by using PEGylated groups. In the future, we have an idea to do bioorthogonal reaction in vitro.
