Quantification of creatinine in biological samples based on the pseudoenzyme activity of copper–creatinine complex

Ferrate(VI) Oxidation of Pharmaceuticals in Hydrolyzed Urine: Enhancement by Creatinine and the Role of Fe(IV)

“…Several studies − have found that imidazole and CRE, when complexed with specific metal ions (e.g., Cu 2+ and Fe 3+ ), can display peroxidase activity to activate H 2 O 2 and generate hydroxyl radical ( · OH). It is also interesting to note that Fe­(III) and H 2 O 2 are considered two major products generated from the self-decay of Fe­(VI), as well as the reaction of Fe­(VI) with organic substrates .…”

Assessment of antidiabetic activity and acute toxicity of leaf extracts from Physalis peruviana L. in guinea-pig

“…WBC and RBC count were determined by hematocytometer method using Türck's solution and saline solution [13,14] . BUN was measured by Berthelot colorimetric method [15] . The determination of creatinine was made by the method of Jaffe using picric acid and 0.4 mol/ L NaOH [16] .…”

A novel cerium(iii)–isatin Schiff base complex: spectrofluorometric and DFT studies and application as a kidney biomarker for ultrasensitive detection of human creatinine

“…The low LOD value was considered as verication of the extreme sensitivity of the applied approach. The contrast between the analytical performance of the current work and other published methods [26][27][28][29][30][31] for creatinine determination is presented in Table 3. From the comparison evaluation, it can be noted that this method exhibited a fast response time, high sensitivity, high accuracy and precision, good reproducibility, applicability, good recovery and effectiveness, a wider linear range and lower values of LOD and LOQ in comparison with other reports.…”

“…The most popular methods used for the analysis of creatinine are based on colorimetry or enzymatic colorimetric methods by Jaffé's reaction, 24 chromatographic methods, 25 LC-UV, 26 low-capacity cation-exchange chromatography, 27 UV/vis spectrophotometry of a copper/creatinine complex, 28 amperometric methods, 29 electrochemical impedance spectroscopy 30 and cyclic voltammetric methods. 31 Herein, we report a Ce-complex C1, which was constructed from the reaction of Schiff base L1 and cerium chloride by a hydrothermal method.…”
