The single Cys residue in the C-terminal domain of bovine eye lens a-crystallin was covalently labelled with 6-bromomethyl-2-(2-furanyl)-3-hydroxychromone. This novel SH-reactive two-band ratiometric fluorescent dye is characterized by excited state

We demonstrate that newly synthesised 7-acetamido-3-hydroxychromones, as well as their parent 3-hydroxychromone (3HC) analogues, exhibit excited-state intramolecular proton transfer reaction in polar protic media including water, resulting in well-re

Ratiometric fluorescent probes based on 3-hydroxyflavone (3HF) are highly sensitive tools for studying polarity, hydration, electronic polarizability, and electrostatics in different microheterogeneous systems, including protein molecules. In the pre

The interactions between an oligomeric heat-shock protein, alpha-crystallin, and its individual subunits with unfolded proteins were monitored by surface plasmon resonance. Immobilization at the sensor chip allowed us for the first time to study isol

The spectroscopic behavior of the 4'-dialkylamino-3-hydroxyflavones in protic environments is very unusual. Previous studies showed that in contrast to other solvatochromic dyes containing carbonyl group (coumarins, Nile Red, PRODAN, etc.), their Sto

3-Hydroxychromones (3HCs) are fluorescent dyes, which respond to solvent perturbations by shifts and changes in the relative intensity of the two well-separated bands in the emission spectra. These bands originate from an excited state intramolecular

Picosecond time-resolved fluorescence spectroscopy has been applied to the studies of excited-state intramolecular proton transfer (ESIPT) dynamics in two 4'-(dialkylamino)-3-hydroxyflavone derivatives (unsubstituted and substituted at the 6-position
