A thioflavin T-based fluorescent probe was synthesized by using o-aminobenzenethiol and copper reagent as raw materials. The results showed that it exhibited relatively high sensitivity and selectivity to Hg2+, and the common metal ions hardly interfered in the determination. The probe could be used for the visual detection of Hg2+ and applied to image intracelluar Hg2+ in living Hela cells. © 2014 Chinese Chemical Society & SIOC, CAS. Source

The title complex [Ni (DTPB)H2Cl]Cl (BF4)2·4H2O (DTPB=1, 1, 4, 7, 7-pentakis(1H-benzimidazol-2-ylmethyl)-1, 4, 7-triazaheptane) has been synthesized and structurally characterized, and its superoxide dismutase (SOD) catalytic activity was investigated by UV spectra. The results showed that the title complex exhibited distorted octahedron geometry, it can inhibit pyrogallol oxidation, IC50 of the complex was 29.8 mg·L-1, and its SOD activity was affected by reaction temperatures and pH values.

The title complex [Cu(BBA)(NO3)](NO3)2 (BBA = [2-(benzotriazol-1-yl)ethyl][2-(benzotriazol-2-yl)ethyl] amine) has been synthesized and structurally characterized. Its crystallizes in triclinic, space group P- 1 with a = 10.003(3), b = 11.399(3), c = 18.186(5) Å, α = 77.184(4), β = 88.573(5), γ = 72.306(5)°, V = 1924.4(9) Å3, Z = 2, F(000) = 894, D c = 1.493 Mg/m3, Mr = 865.31, μ = 0.644 mm-1, the final R = 0.0733 and wR = 0.1722 for 4349 observed reflections with I > 2σ(I). Its polyphenol oxidase (PPO) mimic activity was studied spectroscopically by using pyrogallol as the substrate. The results showed that the kinetics of pyrogallol catalyzed by the complex obeyed the Michaelis-Mentent equation, showing that the PPO catalytic activity of the complex increased with increasing the reaction temperature and pH values.

A dinuclear copper complex [Cu2LCl2](ClO 4)2 (L = 2,2-(piperazine-1,4-Diyl)bis- (N,N-Bis(pyridine-2-ylmethyl)ethan-1-Amine)) has been synthesized and structurally characterized. It crystallizes in triclinic, space group P1 with a = 8.5707(9), b = 10.5083(12), c = 11.4878(13) Å, a = 76.197(2), ß = 88.271(2), γ = 87.855(2)°, V = 1003.81(19) Å3 Z = 1, F(000) = 478, Dc = 1.544 Mg/m3 Mr = 933.60, μ = 1.383 mm-1, the final R = 0.0669 and wR = 0.1486 for 3675 observed reflections with I > 2σ(I). Its catechol oxidase mimic activity was studied spectroscopically by using 3,5-Di-tert-Butylcatechol (3,5-DTBC) as the substrate. The results showed that the kinetics ofcatechol catalyzed by the complex accorded with the Michaelis-Mentent equation, and the catechol oxidase catalytic activity of the complex increased with increasing the pH values.

A zinc-complex [Zn2(L)Cl3]2[ZnCl4] · CH3CN CH3OH · 3H2O (L=1,1,4,7,7-Pentakis (2-pyridyl-methyl) diethylenetriamine) has been synthesized and structurally characterized, and its catalytic activity was investigated by using p-nitrophenyl phosphate(PNPP) as the substrate. The results showed that one zinc) of the complex was coordinated in a distorted trigonal-bipyramidal geometry, and the coordination geometry around another zinc was distorted octahedron. Its catalytic hydrolysis of N was consistent with Michaelis-Mentent model. Several kinetic parameters Vmax, Km and Kcat were examined under different conditions, and maximal catalytic activity of zinc(II)-complex was observed at a temperature of 30 °C and pH=8.0. Source
