Antitumor activity of irradiated riboflavin on human renal carcinoma cell line 786-O
(Springer, 2015-02-01)
Riboflavin (vitamin B-2) is a precursor for coenzymes involved in energy production, biosynthesis, detoxification, and electron scavenging. Previously, we demonstrated that irradiated riboflavin (IR) has potential antitumoral ...
Cost-effective composite electrode for the fast voltammetric screening and determination of riboflavin (B2) and pyridoxine (B6) in pharmaceuticals
(2013-09-23)
Different solid composites made by mechanical dispersions of graphite particles into heated paraffin (from 65 to 80% graphite, in mass) were prepared and assessed in order to optimize their use in electrochemical and ...
A dual control mechanism synchronizes riboflavin and sulphur metabolism in Bacillus subtilis
(2015-10-22)
Flavin mononucleotide (FMN) riboswitches are genetic elements, which in many bacteria control genes responsible for biosynthesis and/or transport of riboflavin (rib genes). Cytoplasmic riboflavin is rapidly and almost ...
Photo-induced generation of the riboflavin-tryptophan adduct and a vibrational interpretation of its structure
(1994)
A pure fraction of a riboflavin-tryptophan adduct was obtained for the first time from a mixture of products resulting from the anaerobic photoirradiation of riboflavin and tryptophan in solution. The procedure used to ...
EFFECTS OF PH AND IONIC MICELLES ON THE RIBOFLAVIN-SENSITIZED PHOTOPROCESSES OF TRYPTOPHAN IN AQUEOUS-SOLUTION
(ELSEVIER SCIENCE SA LAUSANNE, 1991)
The effects of pH and ionic micelles on the rates of product formation following irradiation of riboflavin in the presence of tryptophan were investigated by absorption and fluorescence spectroscopy. Under anaerobic ...
Visible light-induced photooxidation of glucose sensitized by riboflavin
(ELSEVIER SCIENCE INC, 1999)
Ne conducted this study to evaluate the oxidation of glucose induced by visible light in the presence of sensitizers such as methylene blue and flavins (i.e., flavin mononucleotide and riboflavin). The concentration of the ...
The superfamily keeps growing: Identification in trypanosomatids of RibJ, the first riboflavin transporter family in protists
(Public Library of Science, 2017-04)
Background: Trypanosomatid parasites represent a major health issue affecting hundreds of million people worldwide, with clinical treatments that are partially effective and/or very toxic. They are responsible for serious ...
