Studies on Macromolecular Complexing Agents

The role of certain microbial metabolites as specific complexing agents.

The discovery of microbial metabolites—macrotetrolides, siderochromes and boromycin—is reviewed. The structures of these and related compounds provide instructuve examples of how Nature has solved the problem of cornplexing certain rarer elements, such as potassium, iron and boron. The common structural features of these highly specific, natural complexing agents are briefly discussed. It was e...

Release of weak and strong copper-complexing agents by algae1

By means of potentiometric titrations, the copper-complcxing properties of organic compounds released by 21 algal species are characterized. Most eucaryotic species relcascd measurablc amounts (lo-” M) of copper-complexing agents that could be modeled as weak organic acids with log{*&.,,,} = 0.5. Of seven blue-green algal species studied, four produced about 5 x lo+ M concentrations of strong c...

Molecular docking studies on xanthohumol derivatives as novel ‎anticancer agents ‎

A set of Xanthohumol derivatives were selected and molecular docking studies of these ‎compounds on thioredoxin reductase were conducted. Based on new structural patterns using in ‎silico-screening study, new potent lead compounds were designed. The results due to validated ‎docking protocols lead to find that Thr58, Gly57, Gly21, Asp334, Glu163, Ala130, IIe332, ‎Val44 and Gly132 are the main a...

Effect of kidney damage on the mobilisation of mercury by thiol-complexing agents.

Effect of complexing agents on the electrochemical performance of LiFePO4/C prepared by sol-gel method

LiFePO4/C is synthesized via sol-gel method using Fe3+ as iron sources and different complexing agents, followed by sintering at high temperature for crystallization. The amount of carbon in these composites is less than 6.8 wt.%, and the X-ray diffraction experiment confirms that all samples are pure single phase indexed with the orthorhombic Pnma space group. The particle size of the LiFePO4/...
