Ratiometric and intensity-based zinc sensors built on rhodol and rhodamine platforms.

چکیده
A xanthene-forming condensation reaction yields rhodol and rhodamine dyes carrying a zinc-binding ligand that includes the aniline-type nitrogen donor of the fluorophores. Upon zinc coordination in neutral aqueous solution, rhodol RF3 behaves as a ratiometric sensor, and rhodamine RA1 acts as a turn-off intensity-based indicator. Both fluorescent compounds bind the divalent zinc cation with micromolar affinity.

Spirolactamized benzothiazole-substituted N,N-diethylrhodol: a new platform to construct ratiometric fluorescent probes.
A new rhodol dye with an ESIPT unit has been successfully developed, which can serve as a convenient and universal platform for developing ratiometric sensing systems based on the unique spirocyclic ring-opening process. As a model platform, rhodol hydrazide (4) was prepared and it showed ratiometric response toward Cu(2+).
متن کاملA Ratiometric Tetrazolylpyridine-Based “Turn-On” Fluorescent Chemosensor for Zinc(II) Ion in Aqueous Media
Zinc, an essential trace element, is the second most abundant metal in the human body that plays a vital role in numerous biological processes, such as peptide synthesis, DNA synthesis, RNA transcription, metabolism of cells, metalloenzyme regulation, and neurophysiology, and it also induces the formation of b-amyloid, which is related to neurological function. More than 100 enzymes, such as pe...
متن کاملPeptide-Based, Two-Fluorophore, Ratiometric Probe for Quantifying Mobile Zinc in Biological Solutions
Small-molecule fluorescent sensors are versatile agents for detecting mobile zinc in biology. Capitalizing on the abundance of validated mobile zinc probes, we devised a strategy for repurposing existing intensity-based sensors for quantitative applications. Using solid-phase peptide synthesis, we conjugated a zinc-sensitive Zinpyr-1 derivative and a zinc-insensitive 7-hydroxycoumarin derivativ...
متن کاملRhodol Derivatives as Selective Fluorescent Probes for the Detection of HgII Ions and the Bioimaging of Hypochlorous Acid
Two sensors, 1 with a spirolactone group and 2 with a spirolactam group containing a phenyl isothiocyanate moiety, based on rhodol, were designed and synthesized in order to obtain materials with excellent optical properties for the detection of environmentally and biologically important Hg2+ and hypochlorous acid (HClO) ions. The crystal structure of 1 revealed two moieties, a rhodamine-like p...
متن کاملA Novel Ratiometric Probe Based on Nitrogen-Doped Carbon Dots and Rhodamine B Isothiocyanate for Detection of Fe3+ in Aqueous Solution
A ratiometric probe for determining ferric ions (Fe(3+)) was developed based on nitrogen-doped carbon dots (CDs) and rhodamine B isothiocyanate (RhB), which was then applied to selective detection of Fe(3+) in PB buffer solution, lake water, and tap water. In the sensing system, FePO4 particles deposit on the surface of CDs, resulting in larger particles and surface passivation. The fluorescenc...
