In the title mol-ecule, C(8)H(12)N(2)O(2)S, the imidazole ring forms a dihedral angle of 5.9 (2)° with the mean plane of the carboxyl-ate group. In the crystal, mol-ecules are linked by pairs of N-H⋯S hydrogen bonds, forming inversion dimers.

Photocatalytic C-H activation is an emerging area of research. While cerium chloride photocatalysts have been extensively studied, the role of alcohol additives in these systems remains a subject of ongoing discussion. It was demonstrated that the photocatalyst [NEt][CeCl] () produces •Cl and added alcohols exhibit zero-order kinetics.

Intervertebral disc degeneration (IDD) is a degenerative condition associated with impaired mitophagy. MANF has been shown to promote mitophagy in murine kidneys; however, its role in IDD remains unexplored. This study aimed to elucidate the mechanism by which MANF influences IDD development through the regulation of mitophagy.

A pair of aza-BODIPY isomers, 1,7-di--butyl-3,5-dinaphthyl (Nap-BDP) and 1,7-dinaphthyl-3,5-di--butyl (revNap-BDP), were prepared in this study. According to the single crystal X-ray analysis, Nap-BDP exhibited an orthogonal structure. Owing to the difference in orthogonality and -Bu rotation between Nap-BDP and revNap-BDP, their spectral performances, including maximum absorption and emission, full width at half maximum, fluorescence quantum yield, photostability, singlet oxygen generation and photothermal conversion efficiency, were obviously different.

Introduction: High-dose systemic prednisolone is the cornerstone treatment of many autoimmune- and inflammatory diseases. Since prednisolone shows non-linear protein binding at higher serum concentrations, quantification of the unbound prednisolone concentration is important to understand prednisolone pharmacokinetics. We developed a liquid chromatography-tandem mass spectrometry (LC-MS/MS) assay to quantify protein-unbound prednisolone in serum.
