The purpose of this paper is to summarize mode of action of cisplatin on the tumor cells, a brief outlook on the metallocene compounds as antitumor drugs as well as the future tendencies for the use of the latter in anticancer chemotherapy. Molecular mechanisms of cisplatin interaction with DNA, DNA repair mechanisms, and cellular proteins are discussed. Molecular background of the sensitivity ...

The reactions of (eta(5) - C(5)H(5))(2)MCl(2) (M = Ti, Zr, or Hf) with mercaptoazoles (LH(2)), namely, bis(mercaptotriazoles), bis(mercap- tooxadiazoles), and bis(mercaptothiadiazoles) in 2 : 1 molar ratio, respectively, have been studied in dry tetrahydrofuran in the presence of n-butylamine and the binuclear complexes of the type [{(eta - C(5)H(5))(2) M}(2)(L)] (M = Ti/Zr/Hf) are obtained. Te...

in present studies the synthesis, characterization and biological properties ofoxovanadium(iv) coordination compounds of 4[n-(4′-ethylbenzalidene)amino] antipyrinethiosemicarbazone (ebaapts) and 4[n-(2′,4′-dimethylbenzalidene)amino] antipyrinethiosemicarbazone (dmbaapts) with the general composition vox2l (x = c1-, br-, i-, no3-or ncs-) and vo(cio4)2(l)h2o (l = ebaapts or dmbaapts) are describe...

the vo(iv) complexes of tridentate ono schiff base ligands derived from 2- aminobenzoicacid and salicylaldehyde derivatives were synthesized and characterized by ir, uv–vis and elemental analysis. electrochemical properties of the vanadyl complexes were investigated by cyclic voltammetry. a good linear correlation was observed between the oxidation potentials and the electron-withdrawing charac...

Covalent organic framework (COF) particles with hydroxy groups and well-defined micropores have been synthesized used as novel carriers to load a metallocene catalyst—Cp2ZrCl2. The resulting supported catalyst, which had high specific surface area, demonstrated higher catalytic activity, better thermal tolerance, unique nanoconfinment effect during ethylene polymerization, producing polyethylen...

We report a numerical investigation on the catalytic growth mechanism of a single-walled carbon nanotube (SWNT) inside a template SWNT, that is, formation of a double-walled carbon nanotube (DWNT). The molecular dynamics simulations together with complementary ab inito calculations suggest that the DWNT formation from thermally annealed metallocene-encapsulating SWNT goes through formation of m...

This article presents the impact assessment results for spay-dressing of different Metallocene compound fertilizers containing chelated microelements on yield and quality winter wheat seeds Kazanskaya 560 variety. The research was carried out grey forest soils in Kama region Republic Tatarstan 2017–2020. plants were dressed with autumn spring summer period. In autumn, we used fertilizer mangane...
