In the asymmetric unit of the title compound, C13H13N3O3, the 2-(2-methoxphen-yl)ethenyl unit is connected to the methyl-nitro-imidazole 1-methyl-4-nitro-1H-imidazole moiety. The mol-ecule is quasi-planar and the planes of the two rings form a dihedral angle of 0.92 (11)°. The crystal packing can be described as layers parallel to the (011) plane, stabilized by inter-molecular C-H⋯O hydrogen bo...

Reduction currents for H2O2 at a heme peptide (HP)-modified electrodes are suppressed by inhibitors, such as imidazole derivatives. Although this inhibition effect allows determinations of the total inhibition ability of imidazole derivatives, it has no selectivity. In this study the selectivity control of HP-modified electrodes for imidazole derivatives was performed utilizing the thermorespon...

INTRODUCTION In recent years, studies of the reaction rates of small molecules in the presence of synthetic polymers containing catalytically active functions have contributed significantly to the understanding of the mechanism of enzyme behaviour1. Of particular interest in the field of polymeric catalysis have been the studies of the solvolyses of esters catalyzed by polymers containing pende...

p38α mitogen-activated protein kinase (MAPK) is activated in cancer cells in response to environmental factors, oncogenic stress, radiation, and chemotherapy. p38α MAPK phosphorylates a number of substrates, including MAPKAP-K2 (MK2), and regulates the production of cytokines in the tumor microenvironment, such as TNF-α, interleukin-1β (IL-1β), IL-6, and CXCL8 (IL-8). p38α MAPK is highly expres...

A three-step synthesis of 1-{(1S,2S,4R)-7,7-dimethyl-1-[(pyrrolidin-1-yl)methyl]bicyclo[2.2.1]heptan-2-yl}-1H-benzo[d]imidazole, prepared from camphor derived diamine, is disclosed. The absolute configuration at the chiral center bearing benzo[d]imidazole moiety was confirmed by NOESY. structure a newly synthesized compound 1H- and 13C-NMR, 2D NMR, IR spectroscopy, high resolution mass-spectrom...

Cellulose sulfuric acid is an efficient metal-free catalyst for the synthesis of 1,3,5-trisubstituted pyrazoles via the condensation of 1,3-diketones and hydrazines. The reaction was carried out in Solvent-free condition at room temperature and the products were isolated in good to excellent yields. Mild reaction conditions, as well as ease of operation and workup are some advantages of the pro...
