General description

Lumichrome (7,8-Dimethylalloxazine) is a natural metabolite of riboflavin. It is a flourescent photoproduct of riboflavin degradation. It is known to be an effective photosensitizer and a fluorescent dye.

Application

Lumichrome is suitable as a fluorescence probe, metal ion sensor, and may be used for the inactivation of biological contaminants. Its applications are also seen in memory and semiconductor devices.

The spectroscopic behavior of lumichrome (7,8-dimethyl-alloxazine, LC) in aqueous solutions in a pH range from -1.08 to 14.6 is studied. Absorption spectra, fluorescence quantum distributions, quantum yields, and lifetimes are determined. The ionization stage of ground-state LC changes with rising

Extracellular hydrogen peroxide can induce oxidative stress, which can cause cell death if unresolved. However, the cellular mediators of H2O2-induced cell death are unknown. We determined that H2O2-induced cytotoxicity is an iron-dependent process in HAP1 cells and conducted a CRISPR/Cas9-based

We report on photophysical studies of lumichrome (Lc) in water at different pHs, and interacting with the human serum albumin (HSA) protein and β-cyclodextrin (β-CD) in neutral aqueous solutions. We used steady-state and picosecond time-resolved emission spectroscopy to investigate the

Many bacteria use quorum sensing (QS) as an intercellular signaling mechanism to regulate gene expression in local populations. Plant and algal hosts, in turn, secrete compounds that mimic bacterial QS signals, allowing these hosts to manipulate QS-regulated gene expression in
