Fulerenol – właściwości i zastosowanie w naukach biomedycznych

ABSTRACT Fullerenols, the water-soluble derivatives of fullerenes, are currently being recently intensively studied in the context of the possibility of their application in the biomedicine. Due to their hydrophilic properties and the ability to eliminate free radicals, fullerenols may in the future provide a solid alternative to currently used pharmacological methods in chemotherapy, treatment of neurodegenerative diseases and radiobiology. Depending on the research protocol
applied, fullerenols may also act as pro oxidants. The dualistic nature of fullerenols may
contribute to finding new biomedical applications of these agents in the future, by exerting
a cytotoxic or protective effect respectively against cancer cells or healthy cells. Because of
the encapsulated structure of fullerenols, there exists the possibility of their application in
medical diagnostics in the transfer of contrast agents or in the drug transport.
During the planning of an experiment designed to investigate the effects of radiation in
combination with derivatives of water-soluble fullerenes, the possibility of appearance of the
“dose-response effect” should be taken into consideration since it significantly contributes to
one of the two possible effects: protection or sensitization. The same applies to the possibility
of using these compounds as potential neuroprotectors. Fullerenol may protect neurons in
the particular areas of the brain but in the definedcertain doses it may also induce cell death.
A giant leap in the field of nanotechnology not only leads scientists to search for new applications
of nanomaterials such as fullerenols, but also raises the question about their harmful
effect on the environment. High utilization of hardly biodegradable fullerenols increases the
likelihood of their accidental release into natural systems and their bioaccumulation.
Despite convincing evidences about the potential applications of fullerenols in biomedicine,
we still have insufficient knowledge about the mechanism of action of these molecules and
their possible side effects.

    ABSTRACT: We provide the first evidence that a fullerene derivative can be extensively mineralized under environmental conditions by direct photolysis. Dissolved inorganic carbon (DIC) was identified as a major photoproduct of fullerenol, a hydroxylated C(60) molecule and the ratio of moles DIC produced to moles of fullerenol reacted reached 28 or approximately 47% of complete mineralization on extensive irradiation by simulated solar radiation. The direct photoreaction kinetics of fullerenol in dilute aqueous solution can be described by pH-dependent biexponential rate expressions. This photoreaction slowed by a factor of 2 in nitrogen-saturated water. The oxygen dependence is attributed to photoinduced electron or hydrogen atom transfer from fullerenol to oxygen to produce superoxide ions with a quantum yield of 6.2 x 10(-4). Fullerenol can photosensitize the production of singlet oxygen ((1)O(2)) in dilute aqueous solution with quantum yields ranging from 0.10 in acidic water to 0.05 in neutral and basic solution. However our results indicate that chemical reactions involving diffusive encounters between (1)O(2) or superoxide and fullerenol are too slow to significantly contribute to the fast component of fullerenol photoreaction in sunlight. The pH dependence of the direct and sensitized photoreactions is attributed to changes in intramolecular hemiketal formation in fullerenol.

    ABSTRACT: Parkinson's disease (PD) results primarily from the death of dopaminergic neurons in the substantia nigra. Current PD medications treat symptoms; none halt or retard dopaminergic neuron degeneration. The main obstacle to developing neuroprotective therapies is a limited understanding of the key molecular events that provoke neurodegeneration. The discovery of PD genes has led to the hypothesis that misfolding of proteins and dysfunction of the ubiquitin-proteasome pathway are pivotal to PD pathogenesis. Previously implicated culprits in PD neurodegeneration, mitochondrial dysfunction and oxidative stress, may also act in part by causing the accumulation of misfolded proteins, in addition to producing other deleterious events in dopaminergic neurons. Neurotoxin-based models (particularly MPTP) have been important in elucidating the molecular cascade of cell death in dopaminergic neurons. PD models based on the manipulation of PD genes should prove valuable in elucidating important aspects of the disease, such as selective vulnerability of substantia nigra dopaminergic neurons to the degenerative process.

    ABSTRACT: Parkinson's disease (PD) is one of the most common neurodegenerative disorders. Sources of data Literature search using Medline with keywords Parkinson's disease supplemented with previously published papers known to the author. There have been significant recent advances in the understanding of the pathogenesis of the disease. There has also been a greater realization that the disorder may be associated with significant non-motor disturbances in addition to the more commonly recognized motor complications. Although there is growing circumstantial evidence, it remains to be proven whether any of the current treatments for PD have a neuroprotective effect. Although there is no cure, there are several management options for the early treatment of PD. As the disease progresses, further treatment options are available; however, the management of late-stage motor complications and non-motor symptoms remains particularly challenging and will benefit from further clinical research.
