The reaction of 2-hydroxybenzophenone derivatives with europium ions has afforded a new family of luminescent nonanuclear Eu(III) clusters. Crystal structure analysis of the clusters reveals that the metal core comprises two vertex-sharing square pyramidal units. Most of these complexes show emissions typical of Eu(3+) ion under visible light excitation (400-420 nm) at room temperature. Photoph...

The synthesis and the first X-ray structural characterization of a selenenyl selenocyanate, [o-(2,6-diisopropylphenyliminomethinyl)phenyl]selenenyl selenocyanate (), with a stable Se-Se bond are described. The isolation of stable , both in the solid state and in solution, is facilitated by strong intramolecular SeN interaction. The compound , an example of unsymmetrical diselenide, did not exhi...

Antioxidant capacity is the extent to which a compound can eliminate reactive oxygen species, and in vitro methods for its chemical evaluation have been proposed. Among these methods, radical absorbance (ORAC) assay comes close oxidation reaction living body because it generates species that mimic lipid peroxyl involved peroxidation of biological components react phosphate buffer. In this study...

Alkylating agents, mechlorethamine and N-methyl-N'-nitro-N-nitrosoguanidine, induce the production of plasminogen activator in U-87MG cells, an alkylation DNA repair deficient (Mer-) human glioblastoma strain. Enzyme induction was not observed, however, in U-178MG and SH-101 cells, alkylation repair proficient (Mer+) glioblastoma strains, or in HeLa cells, which reactivated and supported well t...

NHC-Pd-PEPPSI-catalyzed α-alkylation of ketones with primary alcohols and tandem Suzuki–Miyaura-coupling/α-alkylation reactions under borrowing hydrogen conditions were reported.

Phenolic and polyphenolic compounds are distributed in plant tissues as a secondary metabolite which compromised multiple imperative physiological phenomena. Herein, inhibition mechanism of human carbonic anhydrase isoform II, hCAII, with seven phenolic including phenol, catechol, resorcinol, 4-methyl vanillic acid, trans-cinnamic acid ortho-coumaric has been investigated using quantum mechanic...
