| 1 | Sensing carboxylesterase 1 in living systems by a practical and isoformspecific fluorescent probe显示文摘Carboxylesterase 1(CES1), one of the most abundant serine hydrolases in mammals, has drawn much attentions in recent years, owing to this enzyme involves in many physiological processes via hydrolysis of both endogenous esters and xenobiotic esters. Herein, to real-time monitor the activities of CES1 in various biological systems, a practical and iso form-specific fluorescent probe was developed on the basis of the substrate preference of CES1, as well as the structural and optical properties of BODIPY dyes. After screening of a panel of BODIPY ester derivatives, probe 1 displayed the best combination of specificity,sensitivity, enzymatic kinetics and applicability for monitoring CES1 activities in real samples. This probe was successfully used to detect CESl activities in several biological systems including tissue preparations,living cells, tissue slices and zebrafish. Furthermore, the biomedical applications of probe 1 for screening of CES1 inhibitors were also demonstrated using tissue preparations or living cells as enzyme sources. In summary, a practical and broadly applicable tool for real-time monitoring CES1 in biological systems was developed and well-characterized, which held great promise for further investigations on CES1-associated drug discovery, clinical practice and fundamental research. | Lele Ding Zhenhao Tian Jie Hou Tongyi Dou Qiang Jin Dandan Wang Liwei Zou Yadi Zhu Yunqing Song Jingnan Cui Guangbo Ge | 2019 | Chinese Chemical Letters2019，30，3： | 2 |
