Achiral, diamagnetic Ni(II) complexes 1 and 3 have been synthesized from Ni(II) salts and the Schiff bases, generated from glycine and PBP (7) and PBA (11), respectively, in MeONa/MeOH solutions. The requisite carbonyl-derivatizing agents pyridine-2-carboxylic acid(2-benzoyl-phenyl)-amide 7 (PBP) and pyridine-2-carboxylic acid(2-formyl-phenyl)-amide 11(More)
We report here a facile preparation of highly water-soluble derivatives C(70)[p-C(6)H(4)(CH(2))(n)COOH](8) (n = 2, 3) starting from readily available chlorinated [70]fullerene precursors C(70)Cl(8) and C(70)Cl(10). The synthesized fullerene derivatives showed pronounced antiviral activity in vitro, particularly against human immunodeficiency virus (HIV) and(More)
We report for the first time the application of chlorofullerene C60Cl6 as a substrate for straightforward preparation of highly water-soluble fullerene derivatives, promising compounds for investigation of the biological action of fullerenes in vitro and in vivo. Methyl esters of phenylacetic and benzylmalonic acids were used as reagents in the(More)
The composition of fluids used in “electronic cigarettes” was studied without preliminary preparation procedures using one- and two-dimensional homo- and heteronuclear 1H and 13C NMR spectroscopy in addition to electrospray ionization mass spectrometry (ESI-MS). It was shown that the main components of the mixtures were non-tobacco products.
Tuberculosis is one of the most common infectious diseases known to man. About 37% of the world's population (about 1.86 billion people) are infected with Mycobacterium tuberculosis. According to the World Health Organization, every year approximately 8 million people develop active tuberculosis and almost 2 million of those die from the disease. The(More)
We report a general synthetic approach to the preparation of highly functionalized amine and amino acid derivatives of [60]fullerene starting from readily available chlorofullerene C(60)Cl(6). The synthesized water-soluble amino acid derivative of C(60) demonstrated pronounced antiviral activity, while the cationic amine-based compound showed strong(More)
Chlorofullerene C(60)Cl(6) undergoes highly selective reactions with thiols forming compounds C(60)[SR](5)H with high yields. These reactions open up straightforward synthetic routes to many functionalized fullerene derivatives, e.g. water-soluble compounds showing interesting biological activities.
Here we report the investigation of photophysical properties and photodynamic action of two novel water soluble hybrid molecular structures based on [60]fullerene dyads bearing covalently attached residues of anthracycline antibiotic "ruboxyl". Molecular structures of the designed compounds were confirmed by IR and UV-VIS absorption spectroscopy,(More)
The synthesis, characterization and photovoltaic study of two novel derivatives of [70]fullerene, phenyl-C₇₁-propionic acid propyl ester ([70]PCPP) and phenyl-C₇₁-propionic acid butyl ester ([70]PCPB), are reported. [70]PCPP and [70]PCPB outperform the conventional material (6,6)-phenyl-C₇₁-butyric acid methyl ester ([70]PCBM) in solar cells based on(More)
We studied 15-crown-5 ether mono- and bis(styryl) derivatives of 2,2'-bipyridine ( and ) as a scaffold to construct photoresponsive complexes possessing metallodendrimer structure. The synthesis and optical properties of one dimensional (1D) Ca(2+)-containing and octahedral 3D Zn(2+)-containing complexes with crowned styryl derivatives of 2,2'-bipyridine(More)
