Metabolite identification and metabolite profiling are of major importance in the pharmaceutical and clinical context. However, highly polar and ionic substances are rarely included as analytical tools are missing. In this study, we present a new method for the determination of urinary sulfates, sulfonates, phosphates and other anions of strong acids. The method comprises a CE separation using an acidic BGE (pH

Synthesis of Sulfonated Peptides Using a Trifluoromethyltoluene-Protected Amino Acid.

J Org Chem

January 2025

Department of Surgery, Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, Massachusetts 02215, United States.

A scalable, seven step synthesis is reported for a trifluoromethyl toluene protected sulfonated phenylalanine building block whose utility was demonstrated in the synthesis of four CXCR4-derived sulfonopeptides. When compared to a conventional trichloroethyl protected building block, overall yield was improved by up to 4-fold. We believe this building block will prove to be of significant value for the synthesis of a variety of peptide targets containing phenylalanine sulfonate, a bioisostere of tyrosine sulfate, enabling orthogonal protection strategies and improving synthetic efficiency and yield.

In the electrocatalytic (EC) degradation process, challenges such as inefficient mass transfer, suboptimal mineralization rates, and limited current efficiency have restricted its broader application. To overcome these obstacles, this study synthesized spherical particle electrodes (FeNi@BC) with superior electrocatalytic performance using a bio-inspired preparation method. A three-dimensional electrocatalytic oxidation system based on FeNi@BC electrode, EC/FeNi@BC, showed excellent degradation efficiency of sulfamethoxazole (SMX), reaching 0.

Serum CS/DS, IGF-1, and IGFBP-3 as Biomarkers of Cartilage Remodeling in Juvenile Idiopathic Arthritis: Diagnostic and Therapeutic Implications.

Biomolecules

November 2024

Department of Clinical Chemistry and Laboratory Diagnostics, Faculty of Pharmaceutical Sciences in Sosnowiec, Medical University of Silesia, ul. Jedności 8, 41-200 Sosnowiec, Poland.

Cartilage destruction in juvenile idiopathic arthritis (JIA) is diagnosed, often too late, on basis of clinical evaluation and radiographic imaging. This case-control study investigated serum chondroitin/dermatan sulfate (CS/DS) as a potential biochemical marker of cartilage metabolism, aiming to improve early diagnosis and precision treatment for JIA. We also measured the levels of insulin-like growth factor-1 (IGF-1) and insulin-like growth factor-binding protein-3 (IGFBP-3) (using ELISA methods) in JIA patients ( = 55) both before and after treatment (prednisone, sulfasalazine, methotrexate, administered together), and analyzed their relationships with CS/DS levels.

Enhanced removal of sulfonamide antibiotics in water using high-performance S-nZVI/BC derived from rice straw.

J Environ Manage

January 2025

Key Laboratory of Jiangxi Province for Functional Biology and Pollution Control in Red Soil Regions, School of Life Science, Jinggangshan University, Ji'an, 343009, China. Electronic address:

Sulfonamide antibiotics (SAs) are widely used in the biomedical field but pose an environmental risk as ecotoxic pollutants. Developing eco-friendly methods to degrade SAs into harmless compounds is crucial. In this work, biochar (BC) was prepared from rice straw via pyrolysis and used to support S-nZVI, thereby forming the S-nZVI/BC composites.
