Applicazioni

4-Bromomethyl-6,7-dimethoxycoumarin was used as fluorescent labeling reagent for the reversed-phase HPLC separation and detection of carboxylic acids. It was also used as derivatization reagent:
  • for quantitation of clofibric, bezafibric and fenofibric acids in liver by liquid chromatography
  • in determination of the concentration of tripeptide glutathione by matrix-assisted laser desorption ionization time-of-flight mass spectrometry
  • for determination of carboxylic acids in chromatographic detection

Kinetic measurement of protein folding is limited by the method used to trigger folding. Traditional methods, such as stopped flow, have a long mixing dead time and cannot be used to monitor fast folding processes. Here, we report a compound

Equilibrium and kinetic fluorescence methods have been used to characterize the interactions between K+ and the Ca(2+)-ATPase of skeletal-muscle sarcoplasmic reticulum. K+ shifts the E2-E1 equilibrium of the ATPase towards E1 and increases the rate of Ca2+ binding to the

4-Bromomethyl-6,7-dimethoxy-coumarin labels the (Ca(2+)-Mg(2+)-ATPase of skeletal muscle sarcoplasmic reticulum at Cys-344. Resonance energy transfer has been used to measure the distance between this site and Lys-515 labelled with fluorescein isothiocyanate as about 37 A. The height of Cys-344 above the

1,2-Dimethylhydrazine (DMH) is a toxic environmental pollutant which was reported also to be a colon-specific carcinogen. This study was performed to study the effect of bis-1,7-(2-hydroxyphenyl)-hepta-1,6-diene-3,5-dione, a bisdemethoxycurcumin analog (BDMC-A) on DMH-induced colon carcinogenesis in male Wistar rats and effects

A reliable and validated reversed-phase high-performance liquid chromatography (HPLC) method using fluorescence detection is reported for the simultaneous quantitation of mycophenolic acid (MPA) and valproic acid (VPA) in human plasma. The method is based on the pre-column derivatization of valproic
