A solution-phase synthesis of active esters of 3′-fluorophore-labeled deoxynucleoside 5′-monophosphates was developed for thymine and cytosine as nucleobases by using two different BODIPY dyes. Starting from the respective 2′-amino-2′,3′-dideoxynucleoside-5′-monophosphate, the fluorescent oxyazabenzotriazolides can be prepared in one-pot procedures involving labeling and activation. Screening of a
通过使用两种不同的 BODIPY 染料,针对胸腺嘧啶和胞嘧啶作为核碱基开发了 3'-荧光团标记的脱氧核苷 5'-单磷酸活性酯的液相合成。从各自的 2'-amino-2',3'-dideoxynucleoside-5'-monophosphate 开始,荧光 oxyazabenzotriazolides 可以在涉及标记和活化的一锅程序中制备。对一系列支持物的筛选导致对珠子进行化学引物延伸测定,通过光学读出原位检测目标 DNA 中的核碱基。
