Article Abstract
A bottom-up approach to achieve full oligosaccharide and glycan characterization has been described that is based on an MSn fragment spectral library and associated tools. The library, identified as FragLib, was initiated with known standards and commercially available oligomers prepared as methylated derivatives. As a component of this effort a set of software tools has been written for storing, organizing, and comparing spectral files, including the identification of isobaric mixtures. These tools provide a facile and objective evaluation of structural details including interresidue linkage, monomer identification, anomeric configuration, and branching. The tools are components of a web-based data sharing interface for sample tracking, spectral searching, and structural confirmation. Applications have been detailed with unknown samples and previously characterized glycoconjugates.

Unlabelled: The global health crisis caused by SARS-CoV-2 underscores the urgent need for effective antiviral therapeutics. The SARS-CoV-2 main protease (Mpro) is a crucial enzyme in viral replication, making it a prime target for drug development. In this study, we designed and evaluated peptide inhibitors targeting Mpro by introducing systematic mutations in the Nsp10/11 cleavage site peptide (QLMPER).

Nitrogen-containing heterocyclic compounds (NHCs), widely present in industrial wastewater, pose significant environmental and health risks, yet their identification and characterization remain poorly understood. Herein, we developed a diagnostic fragment list comprising 20 nitrogen-containing fragments for NHCs, by integrating chemical information from Pubchem with the NIST mass spectral library. Leveraging this list, we employed a diagnostic fragment-assisted nontarget screening approach and identified 151 NHCs in iron and steel industry wastewater.

Water contamination by micropollutants is a global issue, yet there is limited information from low-income regions. To address this, we evaluated surface water quality in rapidly growing Sub-Saharan area of Malawi lacking wastewater treatment. Integrated assessment of passive sample extracts representing wet and dry seasons combined effect-based approach with in vitro bioassays, target and non-target chemical analyses (NTS).
