The interactions of bifendate (DDB) or analogs (Bicyclol, I, II and III) with catalase are analyzed by spectrophotometric methods. The fluorescence spectra results show the intrinsic fluorescence of catalase is strongly quenched by DDB or analogs with a static quenching procedure. The binding constants are obtained at three temperatures. The thermodynamics(More)
A simple, rapid, and sensitive stopped-flow kinetic fluorometric approach was established for the assay of DNA in synthetic samples and real samples by using the measures of initial reaction rate. The increased initial reaction rate is in proportion to the concentration of DNA in the range of 2.0x10(-8)M to 2.1x10(-6)M. The optimum conditions for various(More)
BACKGROUND/AIM To investigate the role of kidney injury molecular 1 (KIM-1) in high glucose-induced autophagy and apoptosis in renal tubular epithelial cells. METHODS Human renal tubular epithelial cells (HK2) were treated with normal glucose (NG, D -glucose 5.6 mmol/L), high glucose (HG, 30 mmol/L), high osmotic (HO, D-glucose 5.6 mmol/L + D-mannitol(More)
The interactions between Trypsin and bifendate (DDB) or analogs (I, II and III) were investigated by fluorescence, UV-visible absorption, resonance light scattering, synchronous fluorescence and 3D spectroscopy under mimic physiological conditions. The results revealed that DDB and analogs caused the fluorescence quenching of Trypsin by the formation of(More)
This work was designed to study the interaction between bovine serum albumin (BSA) and Biphenyldicarboxylate (DDB) or analogs (I, II and III) of DDB by UV-visible and fluorescence spectroscopic methods for the first time. Results showed that both DDB and analogs had a strong ability to quench the intrinsic fluorescence of BSA through a static quenching(More)
