Background: An intensive development of the Fast Liquid Chromatography (FLC) has been recently observed. It makes possible to reduce time analysis and improve resolution as well as sensitivity. The aim of this study was to separate the chosen antioxidants optimization using the FLC method.
Material And Methods: The three various procedures for antioxidants analysis were compared. Mobile phases containing aqueous solution of formic acid, acetic acid, acetonitrile, and methanol were tested. Limit of detection (LOD), limit of quantification (LOQ), linearity and repeatability of each procedures were determined.
Results: Developed procedure enabled to separate all analytes and allowed to get low LOD levels and good repeatability. This procedure was used for antioxidants analysis in buckwheat and buckwheat products.
Conclusion: Fast Liquid Chromatography allows to reduce time analysis and obtain good validation parameters.

This study aimed to investigate the potential hypoglycemic mechanism of red ginseng acidic polysaccharides (RGAP) from the perspective of fatty acid (FA) regulation. A high-glucose/high-fat diet in conjunction with streptozotocin administration was employed to establish type 2 diabetes mellitus (T2DM) rat models, and their fecal FAs were detected using the liquid chromatography-mass spectrometry (LC-MS) method. RGAP treatment alleviated the polyphagia, polydipsia, weight loss, and hyperglycemia observed in T2DM rats.

Cross-coupling reactions are indispensable for the construction of complex molecular scaffolds. In this work, we developed a sustainable methodology for the cross-coupling reaction of arene thianthrenium salts with aryl boronic acids, which can be effectively realized under mechanochemical conditions. Liquid-assisted grinding (LAG) enabled fast and high-yielding synthesis of a range of biaryls via Pd/RuPhos-catalyzed cross-coupling.

Background: Contezolid (CZD) is an analog of Linezolid (LZD) that has demonstrated potent in vitro and in vivo activity against tuberculosis (TB) while presenting a safer side-effect profile. In this study, we evaluated the early bactericidal activity (EBA) of CZD compared to LZD, with LZD serving as a control.
Methods: Naive, smear-positive pulmonary TB patients were enrolled and randomly assigned to receive either a 14-day monotherapy regimen of 600 mg LZD once daily (QD) or 800 mg CZD twice daily (BID).

Bosentan is a dual endothelin receptor antagonist widely used in the treatment of pulmonary artery hypertension. However, there are few reports on the pharmacokinetics (PK) and bioequivalence of bosentan dispersible tablets (32 mg) in the Chinese population. This study aimed to evaluate the PK characteristics and bioequivalence of the test and reference formulations of bosentan dispersible tablets in healthy Chinese volunteers under fasting and fed conditions.

To evaluate the bioequivalence and safety of oral rivaroxaban tablets between a test formulation and a reference formulation in healthy Chinese subjects, a randomized, open, 2-formulation, 4-cycle, complete repeat crossover study was conducted under both fasting and fed states. Thirty-six healthy participants were enrolled separately for the fasting and fed groups, and each subject received a single oral dose of 20 mg of the test or reference formulation of rivaroxaban tablets per cycle. Blood samples were collected at specified intervals, and rivaroxaban was analyzed using liquid chromatography-tandem mass spectrometry.
