Cationic Ru II complexes derived from coumarin hybrids and bipyridine have shown greater cytotoxicity than the free ligands. Our findings been associated to strongest ability of interact with DNA.
The condensation reaction between aminoguanidine bicarbonate and benzoic acid produced 1,2,4-triazole which, after with zinc(II) chloride, led to the formation of a complex, Zn(II)-1,2,4-triazole. This complex decomposes into chloroform leading by-product identified by multinuclear NMR (13C 1H) as benzoate. Subsequently, theoretical study, using Hartree-Fock DFT methods, was applied validate benzoate byproduct decomposition through calculation magnetic shielding tensor (NMR), well address...
A capacidade dos microrganismos, em especial, das bactérias se tornarem resistentes, tem sido amplamente abordada diversas publicações, e as plantas são uma fontes para busca de novos medicamentos, que a cada dia vem tornando mais necessário. Este trabalho, teve por objetivo avaliar formas preparação extratos Brassica oleracea var. capitata testá-las frentes cepa Staphylococcus aureus utilizando ensaio meio sólido difusão ágar, líquido placa ELISA. Os testes revelaram obtidos decocção...
Compounds of Cu(II) and Zn(II) with 3-R-1H-1,2,4-triazole-5-amine {R = methyl (mta), phenyl (pta)} were prepared characterized by infrared spectroscopy (IR), multinuclear NMR (1H, 13C), electronic (UV-VIS), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), microanalyses melting point. Dimeric, monomeric, polymeric materials synthesized in this work. The Zn(II)-1,2,4-triazole derivatives have the metal ion at center two geometric arrangements, being a tetrahedron for...
The condensation reaction between aminoguanidine bicarbonate with carboxylic acids led to the formation of 3-methyl-1H-1,2,4-triazole-5-amine (mta), 3-methyl-1H-1,2,4l4-triazole-5-amine acetate (Hmta) and 3-phenyl-1H-1,2,4-triazole-5-amine (pta). compound N-(3-methyl-1H-1,2,4-triazole-5-yl)propan-2-imine (mpta) was obtained by reacting mta acetone, upon an attempt purifying in this solvent. excess acetic acid Hmta during preparation mta. These compounds were characterised infrared...
