The neuroprotective effect of fullerenols on a model of Parkinson’s disease in Drosophila melanogaster

Abstract Neuroprotective properties of fullerenols С60(OH)30#nbsp;and С70(OH)30#nbsp;have been shown in a Drosophila melanogaster model of Parkinson’s Disease (PD). Fullerenols used in this work demonstrated negligible toxicity even at high concentrations as a result of a specifically developed manufacturing process. It has been shown that the drugs promote restoration of dopamine levels, reduce oxidative stress in… Continue reading The neuroprotective effect of fullerenols on a model of Parkinson’s disease in Drosophila melanogaster

Fullerenol C60(OH)16 prevents amyloid fibrillization of Aβ40-in vitro and in silico approach

The generation of Aβ amyloid aggregates in the form of senile plaques in the brain is one of the pathological hallmarks of Alzheimer’s disease (AD). There is no cure for AD and one of the recent treatment strategies is focused on the inhibition of amyloid fibrillization of Aβ peptide. Fullerene C60 has been proposed as… Continue reading Fullerenol C60(OH)16 prevents amyloid fibrillization of Aβ40-in vitro and in silico approach

Fullerenol nanoparticles decrease ischaemia-induced brain injury and oedema through inhibition of oxidative damage and aquaporin-1 expression in ischaemic stroke

Background:#nbsp;We examined the possible protective effects of fullerenol nanoparticles on brain injuries and oedema in experimental model of ischaemic stroke through inhibition of oxidative damage and aquaporin-1 (AQP-1) expression. Methods:#nbsp;Experiment was done in three groups of rats (N = 66): sham, control ischaemia and ischaemic treatment. Ischaemia was induced by 90-minutes middle cerebral artery occlusion… Continue reading Fullerenol nanoparticles decrease ischaemia-induced brain injury and oedema through inhibition of oxidative damage and aquaporin-1 expression in ischaemic stroke

Preferential binding of fullerene and fullerenol with the N-terminal and middle regions of amyloid beta peptide: an in silico investigation

Amyloid beta (Aβ) deposits are implicated in the pathogenesis of debilitating neurodegenerative disorders such as Alzheimer’s disease. In the present study, the interactions of carbon-based nanoparticles (NPs) such as fullerene and fullerenol having different surface chemistry with Aβ were investigated using molecular dynamics simulations and docking studies. A detailed analysis of docking results showed that… Continue reading Preferential binding of fullerene and fullerenol with the N-terminal and middle regions of amyloid beta peptide: an in silico investigation

Distinct Binding Dynamics, Sites and Interactions of Fullerene and Fullerenols with Amyloid-β Peptides Revealed by Molecular Dynamics Simulations

The pathology Alzheimer’s disease (AD) is associated with the self-assembly of amyloid-β (Aβ) peptides into β-sheet enriched fibrillar aggregates. A promising treatment strategy is focused on the inhibition of amyloid fibrillization of Aβ peptide. Fullerene C60#nbsp;is proved to effectively inhibit Aβ fibrillation while the poor water-solubility restricts its use as a biomedicine agent. In this… Continue reading Distinct Binding Dynamics, Sites and Interactions of Fullerene and Fullerenols with Amyloid-β Peptides Revealed by Molecular Dynamics Simulations

Amphiphilic surface chemistry of fullerenols is necessary for inhibiting the amyloid aggregation of alpha-synuclein NACore

Featuring small sizes, caged structures, low cytotoxicity and the capability to cross biological barriers, fullerene hydroxy derivatives named fullerenols have been explored as nanomedicinal candidates for amyloid inhibition. Understanding the surface chemistry effect of hydroxylation extents and the corresponding amyloid inhibition mechanisms is necessary for enabling applications of fullerenols and also future designs of nanomedicines… Continue reading Amphiphilic surface chemistry of fullerenols is necessary for inhibiting the amyloid aggregation of alpha-synuclein NACore
