چکیده

This paper shows for the first time that the spectral features of the ternary complex of tyrosinase/O2/phenol, trapped at low temperature using the very slow substrate 3,5-difluorophenol, are those of a mu-eta2:eta2-peroxidodicopper(II) species, and that this remains the only enzyme species under turnover and substrate saturation conditions.

In vitro and in silico studies of the inhibitory effects of some novel kojic acid derivatives on tyrosinase enzyme

Objective(s): Tyrosinase is a key enzyme in pigment synthesis. Overproduction of melanin in parts of the skin results in hyperpigmentation diseases. This enzyme is also responsible for the enzymatic browning in fruits and vegetables. Thus, its inhibitors are of great importance in the medical, cosmetic and agricultural fields. Materials and Methods: A series of twelve kojic acid derivatives wer...

Studies on the Enantioselective Iminium Ion Trapping of Radicals Triggered by an Electron-Relay Mechanism

A combination of electrochemical, spectroscopic, computational, and kinetic studies has been used to elucidate the key mechanistic aspects of the previously reported enantioselective iminium ion trapping of photochemically generated carbon-centered radicals. The process, which provides a direct way to forge quaternary stereocenters with high fidelity, relies on the interplay of two distinct cat...

Synthesis and Trapping of 3,4,3',4'-Tetradehydrobiphenyl (Bisbenzyne)

3,3'-Dicarboxy-4,4'-diaminobiphenyl was synthesized from Onitrobenzoic acid following standard procedures. Diazotization of this compound with isoamylnitrite, under approtic condition gave diphenyl-4,4'-bis-diazonium-3,3'-dicarboxylate and subsequent thermal decomposition of this diazonium compound produced 3,4,3',4'-tetradehydrobiphenyl (bisbenzyne) as a reactive intermediate. Bisbenzyne w...
