Exploring Mn-doped ZnS quantum dots for the room-temperature phosphorescence detection of enoxacin in biological fluids.

He Y, Wang HF, Yan XP.SourceResearch Center for Analytical Sciences, College of Chemistry, Nankai University, 94 Weijin Road, Tianjin 300071, China.
Analytical chemistry.Anal Chem.2008 May 15;80(10):3832-7. doi: 10.1021/ac800100y. Epub 2008 Apr 12.
While most research works focus on the development of quantum dots (QDs)-based fluorescence sensors, much less attention is paid to the phosphorescence properties of QDs and their potential for phosphorescence detection. In this work, the phosphorescence property of Mn-doped ZnS QDs is explored to d

Ceftezole, a cephem antibiotic, is an alpha-glucosidase inhibitor with in vivo anti-diabetic activity.

Lee DS, Lee JM, Kim SU, Chang KT, Lee SH.SourceDepartment of Microbiology, Kyungpook National University, Daegu 702-701, Korea.
International journal of molecular medicine.Int J Mol Med.2007 Sep;20(3):379-83.
Using a high throughput-compatible assay to screen for potential alpha-glucosidase inhibitors, we found that the beta-lactam antibiotic ceftezole exhibited potent alpha-glucosidase inhibitory activity. In in vitro alpha-glucosidase assays, ceftezole was shown to be a reversible, non-competitive inhi
