Anwendung

• Simultaneous determination of eight arginine-related metabolites in cellular extracts using liquid chromatography-tandem mass spectrometry.: This study utilized the Chromolith^® RP-18 endcapped column to achieve high-resolution separation of arginine-related metabolites in cellular extracts. The method demonstrated excellent reproducibility and sensitivity, highlighting the column′s effectiveness in complex biological sample analysis (Amatya S et al., 2020).


• Rapid Determination of 30 Polyphenols in Tongmai Formula, a Combination of Puerariae Lobatae Radix, Salviae Miltiorrhizae Radix et Rhizoma, and Chuanxiong Rhizoma, via Liquid Chromatography-Tandem Mass Spectrometry.: The Chromolith^® RP-18 endcapped column was employed for the rapid and efficient determination of polyphenols in a traditional Chinese medicine formula. The column′s high throughput and robust performance facilitated the simultaneous analysis of multiple compounds, demonstrating its application in natural product research (Wang FR et al., 2017).


• Simultaneous Liquid Chromatographic Determination of Ebastine with Two Sympathomimetic Drugs Using a Monolithic Column.: This research applied the Chromolith^® RP-18 endcapped column to the simultaneous chromatographic determination of ebastine and two sympathomimetic drugs. The study underscored the column′s ability to provide rapid and efficient separations in pharmaceutical analysis, ensuring accurate quantification of drug components (Ibrahim F et al., 2017).

Biochem./physiol. Wirkung

Quercetin ist ein Flavonoid mit Anti-Krebs-Aktivität. Quercetin ist eine mitochondriale ATPase und ein Phosphodiesterase-Inhibitor. Es hemmt die Aktivität von PI3-Kinase und in geringerem Maß die Aktivität von PIP-Kinase. Quercetin hat eine proliferationshemmende Wirkung auf Krebszelllinien, verringert das Wachstum von Krebszellen über Typ-II-Östrogenrezeptoren und hält den Zellzyklus von leukämischen T-Zellen des Menschen in der späten G1-Phase an. Außerdem hemmt Quercentin möglicherweise die Aktivität von Fettsäure-Synthase.
