Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 14248-66-9, is researched, Molecular C7H8N2O3, about Methyl-substituted 4-nitropyridine N-oxides as ligands: Structural, spectroscopic, magnetic and cytotoxic characteristics of copper(II) complexes, the main research direction is nitropyridine oxide methylated copper complex preparation antitumor activity; crystal structure copper methylnitropyridine oxide complex; MSBAR methylated nitropyridine copper complex antitumor activity.Electric Literature of C7H8N2O3.
Seven new mono- and dinuclear Cu(II) complexes containing various Me substituted 4-nitropyridine N-oxides as ligands were isolated and characterized physicochem. and biol. The characterization included elemental anal., magnetic and spectroscopic methods (diffuse reflectance and UV-visible absorption, IR, FIR). A single crystal x-ray diffraction anal. was performed for the complex with 2,5-dimethyl-4-nitropyridine N-oxide. Trans- and cis-square planar configuration around Cu ion was established for mono- and dinuclear species, resp. In methanolic solutions the dinuclear species decompose into mononuclear ones with increasing 4 → 6 coordination number with attachment of two solvent mols. The IR spectra showed that the strength of the Cu-ligand bond gauged by the degree of N-O elongation changed irregularly with position and number of Me groups. Cytotoxic studies on the MCF-7 human breast cancer line revealed a structure-activity relation: double blocking of the NO2 group with two CH3 groups rendered the complex completely inactive. The complexes were not significantly active against human cancer cell lines A549 (non-small cell lung carcinoma) and HL-60 (human promyelocytic leukemia) (no data).
