Starting from 4-amino-antipyrine, six new compounds were synthesized and characterized. The new compounds contain moieties with particular properties, such are ionophore (benzo-15-crown-5), fluorescent (nitrobenzofurazan), stable free radical (nitroxide), or other types of biological active residues, like nitroderivatives, antipyrine or isoniazid residues. They were fully characterized by appropriate means (1H and 13C NMR, IR, UV–Vis, fluorescence, EPR, elemental analysis) and some of their biological properties were evaluated. Hydrophobicity (RM0, log P), total antioxidant capacity (TAC), and antimicrobial properties are also presented and discussed. 相似文献

Micromanipulation measurements of biological materials 总被引:9,自引:0,他引:9
Micromanipulation enables the mechanical properties of microscopic biological particles to be measured in particular cells. It is capable of measurements at high deformations, including up to cell bursting. Particles as small as 1 m, with breaking forces as low as 1 N, can be characterised. The method can be enhanced by mechanical modelling to allow intrinsic mechanical properties such as the cell wall elastic modulus to be estimated. Present and potential applications include studying yeast and bacterial cell disruption, mechanical damage to animal cells in suspension cultures and filamentous microorganisms in submerged fermentations, plant cell behaviour in food processing, and flocculation processes. 相似文献
