Complex 2, structurally characterized by single-crystal X-ray crystallography, crystallizes in the monoclinic space group P21/c in a unit cell of a = 0.85257(12) nm, b=2.5358(4) nm, c=1.15151(13) nm, β=118.721(8)°, V=2.183.2(5) nm^3, Z=4, Dc=1.624 gocm 3, μ= 1.367 mm^-1. The complexes, free ligands and chloride copper(II) salt were each tested for their ability to inhibit the growth of two gram-positive (B. subtilis and S. aureus) and two gram-negative (Salmonella and E. coli) bacteria. The complexes showed good antibacterial activities against the microorganisms. The interaction between the com- plexes and calf thymus DNA in aqueous solution was investigated adopting electronic absorption spectroscopy, fluorescence spectroscopy, viscosity measurements and cyclic voltammetry. Results suggest that the two complexes can bind to DNA by intercalative mode. In addition, the result of agarose gel electrophoresis suggested that the complexes can cleave the plasmid DNA at physiological pH and room temperature. Mechanistic studies with different inhibiting reagents reveal that hydroxyl radicals, and a singlet oxygen-like copper-oxo species are all involved in the DNA scission process mediated by the complexes.展开更多

The as-synthesized PSL/MnFe204@SiO2-(CH2)3-NH2 catalyst exhibits enhanced catalytic activity for resolving racemic CLP-4-HTHP to the corresponding optically pure (2R,4S)-CLP-4-HTHP compared to the free PSL. The ees for the former is 2.3 times larger than that for the latter under optimized conditions (99.4% and 44.1%, respectively), although the eep for them are same (99.2%). Meanwhile, the PSL/MnFe204@SiO2-(CH2)3-NH2 catalyst possesses a high saturate magnetization of 59.7 emu/g and could be easily recovered by magnetic separation and reused. The catalytic activity in six recycling tests did not significantly decrease, suggesting its great potential for industrial applications.展开更多
