AB  - The effects of twelve weeks of supplementation with fullerene C60 olive/coconut oil solution on a broad spectrum of parameters in rats were examined. The tissue bioaccumulation of C60 was shown to be tissue-specific, with the liver, heart, and adrenal glands being the organs of the greatest, and the kidney, brain, and spleen being the organs of the smallest accumulation. C60 did not change aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase serum activities level, nor the damage of liver cells DNA. There were no effects of fullerene on prooxidant-antioxidant balance in the liver, kidney, spleen, heart, and brain, nor any visible harmful effects on the liver, heart, aorta, spleen, kidney, and small intestine histology. Fullerene changed the gut microbiota structure towards the bacteria that ameliorate lipid homeostasis, causing a serum triglycerides concentration decrease. However, C60 significantly increased the insulin resistance, serum ascorbate oxidation, and brain malondialdehyde and advanced oxidation protein products level. The deteriorative effects of C60 on the brain and serum could be attributed to the specific physicochemical composition of these tissues, potentiating the C60 aggregation or biotransformation as the key element of its pro-oxidative action.

AB  - An efficient encapsulation of the fullerene into two hydrophobized and one native polysaccharide provided water soluble supramolecular hybrids. After covalent modification of polysaccharides by cholesterol, noncovalent hybrids were prepared by a three-step procedure, including mixing of individual aqueous solutions of hydrophobized, as well as native sugar with solution of the fullerene in pyridine, dialysis and lyophilization. Although the degree of the fullerene incorporation into hydrophobized substrates, cholesterol-levan and cholesterol-pullulan, was lower in comparison to the native polysaccharide levan, hydrophobization provided nanoparticles with improved properties. The particle size distribution, studied by dynamic light scattering and scanning electron microscopy revealed formation of moderately polydisperse aggregates, with the diameter contraction in comparison to the corresponding free polysaccharide, especially in the case of hydrophobized substrates. The morphological examination, done by scanning electron microscopy indicated the self-organization of the fullerene-native polysaccharide to round individual structures, while fullerene-hydrophobized polysaccharide hybrids tend to form networks. The antioxidant activity of the synthesized polysaccharide-C60 noncovalent hybrids versus starting polysaccharides was investigated by the DPPH radical scavenging and the β-carotene-linoleic acid bleaching methods. In all three complexes, the radical scavenging ability of the fullerene remained preserved, and a positive effect of levan hydrophobization was observed.

AB  - The reactivity of the C-2v-symmetric pentakisadduct of C-60 with azomethine ylides and conjugated dienes was studied experimentally and computationally. This derivative possesses four [6,6] double bonds, each with unique electrophilicity. The Diels-Alder reaction studied is a regiospecific, kinetically and thermodynamically guided [4 + 2] process producing [5:1]-hexaadducts with an octahedral addition pattern. The kinetically controlled Prato reaction gives a mixture of regioisomeric [5:1]-hexaadducts. The synthesis of geometrically well-defined supramolecular architectures may benefit from these new types of highly functionalized [5:1]-hexaadducts.

AB  - The synthesis, characterization and behaviour of two novel Leigh-type amide [2]rotaxanes are reported. NMR study shows that fullerosteroidal and disteroidal rotaxanes occur in a peptide co-conformation in CDCl3. [D-6]DMSO induces fast unthreading of disteroidal rotaxane, which includes steroid co-conformers as intermediates. On the other hand, fullerosteroidal rotaxane undergoes predominantly a shuttling process occupying the stacked co-conformation, whereas unthreading is very slow in comparison with its disteroidal analogue (25% after 7 days). Moreover, organogelation and self-organization properties were studied. It was found that disteroidal rotaxane is an organogelator and its SEM image shows that it forms a branched film-like network in a PhMe/EtOAc 1 : 1 mixture.

AB  - A series of N-substituted fulleropyrrolidines containing peptide side chain was synthesized by the quantitative, TFA-mediated deprotection of the corresponding tert-butyl esters. The structures of all compounds were determined by comparative analysis of spectroscopic and spectrometric data. The electrochemical characterization, conducted by cyclic voltammetry at room temperature confirmed slightly attenuated reducibility in comparison to pristine C-60 and a weak long-range electron-accepting effect of the Gly(3)-fragment. The introduction of the peptide subunit led to improved solubility and enabled examination of the antioxidant properties in water environment. A notable radical scavenging activity of the fullerene subunit remained almost unchanged in all compounds. The investigation of the supramolecular self-assembling, performed by the scanning electron microscopy revealed an influence of the side chain, particularly the fraction of the hydrophobic residue, as well as the substrate structure on the final morphology. Most of the compounds underwent highly ordered multi-stage hierarchical assembling to the attractive, flower-shaped supramolecular aggregates during both the precipitation and slow evaporation of the solvent.

AB  - Due to their unique physicochemical and electronic properties, emerging fromhighly conjugated π-system, derivatives of the fullerene C60 are interesting buildingblocks in the synthesis of the more complex target molecules. Diverse derivatizationsof hydrophobic carbone sphere provide a wide range of products for the use inmatherial, supramolecular and medicinal chemistry. Since the increase of the numberof addends on the carbon core improves the solubility and varies the stereoelectronicproperties, each method of the controlable multiple derivatization of fullerenes ishighly useful.Prato's reaction is one of the most common methodes for the covalentmodification of fullerenes. The fulleropyrrolidines, products with well definedstructures, are frequently used as intermediers in further chemical transformations offullerenes. This reaction is limited with the easy and unselective formation of bis- andtris(pyrrolidino) adducts and, hence, decrease of the yields and the purity ofmonoadducts. On the other hand, bisadducts are very useful in some aspects of themedicinal and electrochemistry. During the recent period, the regioselective synthesisof the fullerene bisadducts via templated supstrates has been the topic of interest ofseveral researcher groups.In this work, a series of alkyl-tethered diglycines were synthesized andunderwent the Prato's biscycloaddition conditions in aim to obtain templatedbis(pyrrolidino)fullerenes. The first part of the work refers to the optimization of thebiscycloaddition conditions on the octamethylene-tethered substrate.

AB  - Michael addition of aldehydes to nitro-olefins is an effective method to obtain useful chiral gamma-nitroaldehydes. gamma-Nitroaldehydes are precursors for chiral gamma-aminobutyric acid analogues, which have numerous pharmacological activities and are used for the treatment of neurological disorders. A whole-cell system based on recombinantly expressed 4-oxalocrotonate tautomerase (4-OT) was developed and shown to be an effective biocatalyst for the Michael addition of branched aldehydes to beta-nitrostyrenes. The aim of this study was to investigate the influence of the substitution of the N-terminal proline with lysine and arginine, both containing a reactive epsilon-amino group, on the Michael addition catalyzed by 4-OT. First, the effects of these mutations were examined by in silico analysis, followed by the generation of three terminal lysine mutants. The generated mutants, 4-OT_K, 4-OT_PK and 4-OT_KK were tested for their ability to utilise beta-nitrostyrene (1), (E)-1-nitro-2-(2-thienyl)ethene (2) and trans-p-chloro-beta-nitrostyrene (3) as Michael acceptors with isobutanal (2-methylpropanal) as the donor. For comparison, the lithium salt of lysine was used in the same organocatalytic reactions. In general, the introduction of lysine had a negative effect on Michael additions based on overall product yields. However, additional lysine residues at the N-terminus of the protein resulted in structural changes that enhanced the activity towards 2 and 3. Therefore, the N-terminal proline is important for 4-OT-catalysed Michael-additions, but it is not essential.

AB  - We synthesized three dumbbell-like compounds 2a-c, each containing two C-60 groups at the periphery and pyromellitic diimide (PMDI) in the middle, and examined their electronic as well as assembly characteristics with both experimental and computational methods. Cyclic voltammetry (CV) measurements revealed that each of three electron-accepting (AAA) triads could accommodate up to eight electrons. Computational studies (density functional theory, DFT) of 2a-c at PBEPBE/6-311G(d, p) level of theory, with B3LYP/6-31G(d) optimized geometries, revealed that HOMO-LUMO energy gaps are similar to those of the model compound [6,6]-phenyl-C-61-butyric acid methyl ester (PCBM). Compounds 2a-c were also found to assemble into vesicles and nanoparticles on the copper grid (100-300 nm, TEM), while giving more sizeable aggregates after a deposition on the glass (SEM,  gt  5 mm). Understanding the packing of 2a-c on various solid substrates, as well as the assembly characteristics in general, is important for tuning the properties and fabrication of electronic/optical devices. On the basis of the results of conformational analysis (MM and DFT calculations), we deduced that different alkyl spacers in 2a-c ought to play a role in pi-pi interactions between the aromatic components of the triad to guide the packing and therefore morphology of the material.

AB  - Two different alpha,omega-diglicynes linked by linear polyoxaalkyl chains in the presence of formaldehyde underwent Prato reaction to the fullerene C-60. The shorter linker templated formation of only cis-bisadducts, while the longer one afforded a mixture of four bisadducts (all cis and the equatorial) and difullerene dumbbell compound. Their structures were confirmed by the extensive analysis of the spectral data and molecular symmetry, as well. All compounds expressed an ability to arrange into hierarchically ordered supramolecular aggregates, the form of which depended both on the addition pattern and the spacer structure. The attenuated electron-accepting affinity, examined by cyclic voltammetry was in agreement with diminished delocalization of the pi-electronic system. In addition, all compounds exerted a notable radical scavenging activity.

AB  - The potential use of amphiphilic fullerene derivatives as a bionanomaterial was investigated by cyclic voltammetry (CV), scanning electron microscopy (SEM), and the ferrous ion oxidation-xylenol orange (FOX) method. Despite the disrupted delocalization of the pi-electronic system over the C-60 sphere, its antioxidant capacity remained high for all twelve derivatives. The compounds expressed up to two-fold and 5-12-fold better peroxide quenching capacity as compared to pristine C-60 and standard antioxidant vitamin C, respectively. During precipitation and slow evaporation of the solvent, all compounds underwent spontaneous self-assembly giving ordered structures. The size and morphology of the resulting particles depend primarily on the sample concentration, and somewhat on the side chain structure.

AB  - The one-pot bistycloaddition of alkyl-tethered diglycines to C-60 provided five series of bridged bis(pyrrolidino)fullerenes with good regioselectivity, giving mainly cis-2 and cis-3 products. An influence of the bridge length and addition pattern on spectroscopic properties, as well as on the shape of hierarchically organized supramolecular structures was observed. Additional investigation of all synthesized compounds confirmed their strong in vitro antioxidant activity 4-10-fold better than the standard antioxidant vitamin C.

AB  - Four fullerosteroidal conjugates, previously confirmed to express two- to threefold better antioxidant activity in vitro than C-60, were subjected to additional studies, including electrochemical, theoretical, and morphological examination. All tested compounds underwent reversible, diffusion-controlled reductions. A notable influence of the solvent properties on the reduction potential, the level of aggregation, and the lowest unoccupied molecular orbital (LUMO) energy was observed. Theoretical calculations indicated that the energy gain obtained by an intermediate formation, together with compounds' polarizability, polarity, and lipophilicity contributed to the radical quenching capacity. Very large supramolecular aggregates of all fullerosteroidal esters with no hierarchical arrangement were observed in precipitated samples, while solvent induced self-assembling led to round nanoplates, which further arranged to flower-shaped hierarchically ordered architectures or uniformly distributed discoid particles. As in electrochemical studies, fine tuning of the aggregation level was achieved by the solvent.

Previously synthesized fulleropyrrolidinic acid and pregnenolone were connected by peptide linker using a multistep DCC/DMAP and/or EDC/HOBT esterification/amidation procedure. The hybrids were characterized by comparative analysis of spectroscopic data obtained from FUR, UV-vis, HRMS, and extensive NMR experiments (H-1, C-13, COSY, HSQC, and HMBC). The self-assembling properties and morphology of triads samples prepared by drop-drying method were examined by scanning electron microscopy (SEM).

AB  - Synthesis of gamma-nitroaldehydes from branched chain aldehydes and a range of alpha,beta-unsaturated nitroalkenes was achieved by a whole-cell biocatalytic reaction using 4-oxalocrotonate tautomerase as catalyst. Under mild conditions, cyclic and acyclic branched aldehydes were converted into synthetically valuable quaternary carbon containing gamma-nitroaldehydes. The yields of the desired products were influenced by reaction condition parameters such as organic solvent, temperature and pH. The whole-cell biocatalytic approach to the generation of alpha,alpha-substituted gamma-nitroaldehydes was compared to the organocatalytic approach involving the lithium salt of phenylalanine as a catalyst. As the resulting gamma-nitroaldehydes exhibited moderate antifungal activity and mild in vitro cytotoxicity against human fibroblasts (0.2-0.4 mM) they could further be examined as potentially useful pharmaceutical synthons.

abstract = "Synthesis of gamma-nitroaldehydes from branched chain aldehydes and a range of alpha,beta-unsaturated nitroalkenes was achieved by a whole-cell biocatalytic reaction using 4-oxalocrotonate tautomerase as catalyst. Under mild conditions, cyclic and acyclic branched aldehydes were converted into synthetically valuable quaternary carbon containing gamma-nitroaldehydes. The yields of the desired products were influenced by reaction condition parameters such as organic solvent, temperature and pH. The whole-cell biocatalytic approach to the generation of alpha,alpha-substituted gamma-nitroaldehydes was compared to the organocatalytic approach involving the lithium salt of phenylalanine as a catalyst. As the resulting gamma-nitroaldehydes exhibited moderate antifungal activity and mild in vitro cytotoxicity against human fibroblasts (0.2-0.4 mM) they could further be examined as potentially useful pharmaceutical synthons.",
