In view of the significant effect of biothiols, quantitative evaluation and discrimination of intracellular Cys\/Hcy and GSH in complex biological environments is very important. In this study, probe CDS-NBD, synthesized by attaching 2,4-dinitrobenzenesulfonate (DNBS, site 1) and nitrobenzoxadiazole (NBD, site 2) as the highly sensitive and selective dual response site for thiols onto the coumarin derivative 7-hydroxycoumarin-4-acetic acid, exhibited large separation of the emission wavelengths, fast response, notable fluorescence enhancement, excellent sensitivity and selectivity to Cys\/Hcy and GSH over other biological species. Additionally, CDS-NBD could make a distinction between two different fluorescent signals, GSH (an obvious blue fluorescence) and Cys\/Hcy (a mixed blue-green fluorescence). Further study on imaging of Cys\/Hcy and GSH in vivo by employing probe CDS-NBD could also be successfully achieved.<\/jats:p>","DOI":"10.3390\/bios12111056","type":"journal-article","created":{"date-parts":[[2022,11,22]],"date-time":"2022-11-22T02:59:22Z","timestamp":1669085962000},"page":"1056","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Dual Response Site Fluorescent Probe for Highly Sensitive Detection of Cys\/Hcy and GSH In Vivo through Two Different Emission Channels"],"prefix":"10.3390","volume":"12","author":[{"given":"Huiling","family":"Hou","sequence":"first","affiliation":[{"name":"Achievement Transformation Center, Qiqihar Medical University, Qiqihar 161006, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qi","family":"Liu","sequence":"additional","affiliation":[{"name":"Research Institute of Medicine & Pharmacy, Qiqihar Medical University, Qiqihar 161006, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiangbao","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Pharmacy, Qiqihar Medical University, Qiqihar 161006, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuang","family":"Fu","sequence":"additional","affiliation":[{"name":"College of Pharmacy, Qiqihar Medical University, Qiqihar 161006, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9247-9968","authenticated-orcid":false,"given":"Hongguang","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Pharmacy, Qiqihar Medical University, Qiqihar 161006, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuang","family":"Li","sequence":"additional","affiliation":[{"name":"College of Pharmacy, Qiqihar Medical University, Qiqihar 161006, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Song","family":"Chen","sequence":"additional","affiliation":[{"name":"College of Pharmacy, Qiqihar Medical University, Qiqihar 161006, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peng","family":"Hou","sequence":"additional","affiliation":[{"name":"College of Pharmacy, Qiqihar Medical University, Qiqihar 161006, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"127914","DOI":"10.1016\/j.molstruc.2020.127914","article-title":"A novel boranil-based turn-on fluorescent probe for imaging of biothiols in living cells","volume":"1209","author":"Ren","year":"2020","journal-title":"J.
