A novel coumarin-based fluorescent probe for selective detection of bissulfite anions in water and sugar samples

An ‘OFF–ON’ fluorescent probe for specially recognize on Cys and its application in bioimaging

“…In our group, we always expect to obtain the specific probe for distinguishing among Cys, Hcy and GSH. We aimed excellent coumarin fluorophore and maleimide bonding groups to design a series of fluorescent probes [47][48][49][50]. The result is outstanding, we found that N-[4-Methylcoumarin-7-yl]maleimide can specially recognize on Cys, and Hcy, GSH did not disturb the determination of Cys.…”

A new fluorescent enhanced probe based on (E)-9-(2-nitrovinyl)-anthracene for the detection of bisulfite anions and its practical application

“…And in acid medium, it is a very effective antimicrobial agent [1,2]. But in recent years, it was discovered that certain concentration of bisulfite levels could cause asthmatic attacks and allergic reactions in some individuals.…”

“…Chao et al [1] developed a turn-off fluorescent probe for bisulfite detection based-on fluorescent Red GK. Yin et al [2] have successfully utilized a coumarin-based derivative to develop a turn-on fluorescent probe for bisulfite detection in water. Guo et al [36] reported a fluorescent turn-on probe for bisulfite based on hydrogen bond-inhibited C@N isomerization mechanism.…”

A fast‐responsive fluorescent probe for sulfite and its bioimaging

“…As an alternative, the fluorescence method has received much attention due its the advantages of convenience, high sensitivity, fast response and ease of live-cell imaging (14)(15)(16). Fluorescent probes for SO 3 2-have been mainly based on the addition to an aldehyde moiety or a nucleophilic addition (17)(18)(19)(20)(21)(22)(23)(24)(25), and levulinate cleavage mediated by SO 3 2- (26)(27)(28)(29)(30)(31)(32)(33)(34)(35). However, these probes suffer from low selectivity in the presence of biothiols such as cysteine, homocysteine, glutathione and a relatively long reaction time, which are not suitable for detecting or imaging SO 3 2-in living cells.…”
