Berberine is an isoquinoline alkaloid with multiple pharmacological actions, including anti-inflammatory activity. The aims of this study were to examine the effect of berberine on the mucosal healing process and to investigate whether berberine can inhibit the increased production of interleukin-8 in trinitrobenzene sulfonic acid-induced colitis in rats. Berberine was administered orally for 3...
New sulfonic acid functionalized ionic liquids (SAFILs) with bis(trifluoromethylsulfonyl)imide anions were synthesized. These ionic liquids are strong Brønsted acids and can solubilize metal oxides. Water-immiscible SAFILs were used as organic phases in solvent extraction studies.
Методами спектроскопии ИК- и ЯМР Н С с использованием теоретических расчетов (программы ChemDrawUltra, Marvin, ACD/Labs) изучены спектральные характеристики L-цистеинсульфоновой кислоты (L-cysSOH) в растворах виде частично протонированной формы (SO)CHCH(NH)COO-(рН=3) депротонированного иона(SO-)CHCH(NH)COO-(рН=10). Установлено, что отличие от спектров кислоты, спектрах не наблюдается сильного с...
The designed aromatic amide discotic molecule with sulfonic acid groups at its periphery exhibits a hexagonal supramolecular columnar liquid crystalline phase, which leads to the achievement of anisotropic ionic conductivity through macroscopically aligning the ionic channels.
Time-resolved EPR spectra of UV-irradiated Nafion reveal the formation of spin-polarized excited triplet states and allow the detection of photoinduced triplet-triplet energy transfer processes through hydrogen bonds between water and sulfonic acid groups.
