The development of low-cost catalytic systems that mimic the activity of tyrosinase enzymes (Catechol oxidase) is of great promise for future biochemistry technologic demands. Herein, we report the synthesis of new biomolecules systems based on hydrazone derivatives containing a pyrazole moiety (L1-L6) with superior catecholase activity. Crystal structures of L1 and L2 biomolecules were determi...
Two mononuclear copper(II) ibuprofenate adducts with imidazole or 2-methylimidazole and two binuclear copper(II) ibuprofenate adducts with metronidazole or caffeine have been prepared and characterized. Elemental analyses, UV-VIS, IR, EPR, and magnetic moment data for imidazole or 2-methylimidazole adducts are consistent with mononuclear square planar complexes that contain two ibuprofenato lig...
To make low-cost catalytic materials that mimic the activity of tyrosinase enzymes 29 (Catechol oxidase) is an exciting challenge of biochemical technology. Herein, we report the 30 synthesis of a series of acylhydrazone-pyrazoles based biomolecule materials (L1-L7) with superior 31 catecholase activity. These biomolecules were synthesized by a one pot chemical condensation 32 between 5-methyl-...
Two structurally related compounds, phenyl dithiocarbamate sodium salt (I) and p-phenylene-bis (dithiocarbamate) sodium salt (II) were prepared by reaction of the parent aniline and p-phenylenediamine with CS₂ in the presence of sodium hydroxide. These water soluble compounds were characterized by spectroscopic techniques, IR, ¹H NMR and elemental analysis. The inhibitory effects of both compou...
