Toxic Effect of Fullerene and Its Derivatives upon the Transmembrane β2-Adrenergic Receptors

open access: yesMolecules, 2022
Numerous experiments have revealed that fullerene (C60) and its derivatives can bind to proteins and affect their biological functions. In this study, we explored the interaction between fullerine and the β2-adrenergic receptor (β2AR).

Recursive generation of IPR fullerenes [PDF]

open access: yes, 2015
We describe a new construction algorithm for the recursive generation of all non-isomorphic IPR fullerenes. Unlike previous algorithms, the new algorithm stays entirely within the class of IPR fullerenes, that is: every IPR fullerene is constructed by ...

Occurrence of natural fullerene C60 from the iridium-rich Cretaceous-Paleogene (K-Pg) boundary layers of the Um-Sohryngkew river section, Meghalaya, India

open access: yesCarbon Trends, 2023
The presence of fullerene C60 in the iridium-rich Cretaceous-Palaeogene (K-Pg) boundary layer from the Um-Sohryngkew river section of Meghalaya is reported here for the first time. Different analytical methods, including transmission electron microscopy (

Fullerene derivatives and fullerene superconductors [PDF]

open access: yesJournal of Physics and Chemistry of Solids, 1993
Abstract A series of 1:1 C 60 cycloaddition adducts, C 60 A (A = anthracene, butadiene, cyclopentadiene and methylcyclopentadiene), has been synthesized. The products are cleanly separated and characterized by use of TGA, 1 H-NMR, IR, and mass spectrometry. Among these adducts, C 60 , (methylcyclopentadiene) showed the highest thermal stability and

Fullerene Black: Relationship between Catalytic Activity in n-alkanes Dehydrocyclization and Reactivity in Oxidation, Bromination and Hydrogenolysis

open access: yesEurasian Chemico-Technological Journal, 2001
The reactivity of fullerene black in oxidation (by air oxygen or ions MnO4–or Cr2O7 2– in solution), bromination (by Br2 or (C4H9)4NBr3) and hydrogenolysis (without hydrogenation catalyst) are studied.

Fullerenes: Characteristics of the substance, biological effects and occupational exposure levels

open access: yesMedycyna Pracy, 2016
Fullerenes are molecules composed of an even number of carbon atoms of a spherical or an ellipsoidal, closed spatial structure. The most common fullerene is the C60 molecule with a spherical structure – a truncated icosahedron, compared to a football ...

Biogenic fullerenes?

open access: yesInternational Journal of Astrobiology, 2003
If the discoveries of C60 and C70 fullerenes in terrestrial hard rocks are real, then some of these may have formed in the solid state by dehydrogenation-driven ‘zip-up’ of C60Hn and C70Hm progenitors. At three sites of such fullerene discoveries the building blocks for these large molecules may have come from algal remains.
