The synthesis of a maltol-derived hydrazide is described which, once attached to a cell surface, induces rapid multicellular aggregation selectively in the presence of Fe(3+) ions. Heterocellular aggregates are also reported.

     In this study a new simple selective and sensitive spectrophotometric procedure for determination of Fe(III) is described. It is based on the formation of a colored complex between ferric iron and ethyl maltol, a strong and highly selective ligand for Fe(III). After mixing sample and reagent, and incubating at the room temperature, Fe(III)-ethyl maltol complex was extracted with different ...

a b s t r a c t   zinc deficiency in man is characterized by skin lesion, alopecia and has been linked to growth retardation and mental disturbance. for supplementation purposes zinc is currently presented as its sulfate salt, from which uptake by the body is poor, necesseting the administration of high doses. this leads to a range of unpleasant side effects. in order to increase the bioavailab...

earth’s crust and has been implicated as an etiologic factor in neurological disorders including Alzheimer’s disease, Parkinson’s dementia syndrome, and dialysis encephalopathy syndrome. In fact, some evidence supports the selective accumulation of Al within neurons containing neurofibrillay tangles in patients with Alzheimer’s disease and within the aging human brain. Meiri et al., have also r...

As part of a study to characterize the detailed coordination behavior of Pu(IV), single crystal X-ray diffraction structures have been determined for Pu(IV) and Ce(IV) complexes with the naturallyoccurring ligand maltol (3-hydroxy-2-methyl-pyran-4-one) and its derivative bromomaltol (5-bromo-3-hydroxy-2-methyl-pyran-4-one). Although Ce(IV) is generally accepted as a structural analog for Pu(IV)...

Diabetic nephropathy is one of the serious complications in patients with either type 1 or 2 diabetes mellitus but current treatments remain unsatisfactory. Results of clinical research studies demonstrate that Panax ginseng can help adjust blood pressure and reduce blood sugar and may be advantageous in the treatment of tuberculosis and kidney damage in people with diabetes. The heat-processin...

objectives: iron chelators, such as maltol and kojic acid, have antioxidant and anti-inflammatory properties. they may have beneficial effects on inflammatory bowel disease (ibd) because iron can develop and aggravate inflammation in ibd. in the present study, the effect of selected iron chelators and anti-oxidants were evaluated on a model of trinitrobenzene sulfonic acid (tnbs)-induced coliti...
