Novel ratiometric fluorescent probe with large Stokes shift for selective sensing and imaging of Zn in live cell.

A novel ratiometric fluorescent probe, namely 5-[(3-dicyanoylidene -5.5-dimethyl) cyclohexenyl-1-ethenyl] salicylaldehyde-3'-hydroxybenzohydrazone (DCSH) is presented for the selective sensing of Zn ion in acetonitrile/water (2/3, pH 7.4) solution.

A novel multi-functional fluorescent probe for dual-channel detection of SO and Hg and dynamic visualization of SO fluctuations in vivo upon mercury exposure.

Although there are many drugs used for the treatment of mercury poisoning, it is remains confused that pathological symptoms associated with Hg-induced oxidative stress. It is reported that SO can be generated as the anti-oxidant, and plays an important role in maintaining redox balance in cells. There has not yet been a study to precisely track the changes in SO during mercury ion poisoning.

Diethyl (Z,Z)-3,3'-(ethane-1,2-diyldiimino)dibut-2-enoate.

The title compound, C14H24N2O4, is an intermediate in the synthesis of the corresponding heterocyclic compounds. The molecule lies about a twofold axis and has a 'twist' conformation; it adopts the Z,Z configuration, which is shown to be governed mainly by intramolecular hydrogen bonds.
