report, a vastly improved method for the synthesis of [2.2.3]-triazacryptand (TAC), an excellent K+-selective cryptand, is disclosed, which provides a shorter synthetic route with > fivefold higher overall yield. On the basis of the improved synthesis, a TAC-BODIPY conjugate was developed for K+ sensing. TAC-BODIPY is a fluorescence turn-on K+ sensor exhibiting high selectivity toward K+ over other biologically
在本报告中,公开了一种极大改进的 [2.2.3]-三氮杂密码体 (TAC) 合成方法,该方法是一种出色的 K+ 选择性密码体,该方法提供了更短的合成路线,总产率提高了 5 倍以上。在改进合成的基础上,开发了用于 K+ 传感的 TAC-BODIPY 偶联物。TAC-BODIPY 是一种荧光开启 K+ 传感器,与其他生物相关金属阳离子相比,对 K+ 表现出高选择性。介绍了细胞成像研究并证明 TAC-BODIPY 适用于活细胞中的动态 K+ 传感。
