During the course of our systematic investigation of the metabolism of flavonoids, the polymethoxyflavone nobiletin, occurring in the fruits of Citrus depressa, was orally administered to rats. The urinary metabolites were separated and identified by three-dimensional HPLC equipped with a photodiode array detector and the structure was determined by spectroscopic methods to be 4'-hydroxy-3',5,6,7,8-pentamethoxyflavone (1).

Chitosan nanoencapsulation of Turbinaria triquetra metabolites in the management of podocyturia in nephrotoxic rats.

Sci Rep

January 2025

Chemistry of Natural and Microbial Products Department, Pharmaceutical and Drug Industries Research Institute , National Research Centre, Dokki, Cairo, 12622, Egypt.

Cisplatin is a chemotherapeutic drug, which exhibits undesirable side effects. Chitosan nanoparticles are promising for drug delivery. The aim of this study was to determine the effect of the brown alga Turbinaria triquetra ethyl acetate fraction and polysaccharides, either loaded on chitosan nanoparticles or free, against podocyturia and cisplatin nephrotoxicity in rats.

Chronic kidney disease (CKD) stands as a formidable global health challenge, often advancing to end-stage renal disease (ESRD) with devastating morbidity and mortality. At the central of this progression lies podocyte injury, a critical determinant of glomerular dysfunction. Compound K (CK), a bioactive metabolite derived from ginsenoside, has emerged as a compelling candidate for nephroprotective therapy.

Dissecting the genetic mechanisms underlying urinary metabolite concentrations can provide molecular insights into kidney function and open possibilities for causal assessment of urinary metabolites with risk factors and disease outcomes. Proton nuclear magnetic resonance metabolomics provides a high-throughput means for urinary metabolite profiling, as widely applied for blood biomarker studies. Here we report a genome-wide association study meta-analysed for 3 European cohorts comprising 8,011 individuals, covering both people with type 1 diabetes and general population settings.

Key Laboratory of Soil Environment and Pollution Remediation, Institute of Soil Science, Chinese Academy of Sciences, Nanjing 210008, China. Electronic address:

Chinese people are experiencing phthalate exposure risks. However, temporal and regional phthalate internal exposure variations amongst Chinese have not been established. To address this gap, we integrated our 69 adult participants' bio-monitored urinary phthalate metabolite (UPM) concentration data by high-performance liquid chromatography with mass spectrometry in Xi'an and Nanjing and the data from 35 literature (total sample size: 18768).

The interplay between multiple organs, known as inter-organ crosstalk, represents a complex and essential research domain in understanding the mechanisms and therapies for kidney diseases. The kidneys not only interact pathologically with many other organs but also communicate with other systems through various signaling pathways. It is of paramount importance to comprehend these mechanisms for the development of more efficient therapeutic strategies.
