Trypan blue dye exclusion method was used in experiment. X-ray single-crystal analysis has revealed that compound 1 （C32H32Cu2O10） crystallizes in the monoclinic system, space group C2/c, Mr = 703.66, a = 47.340（5）, b = 6.6613（4）, c = 22.028（2）A,β = 113.284（4）°, V = 6380.6（10） A^3, Z = 8, Dc= 1.465 g/cm^3, F（000） = 2896,μ = 1.388 mm^-11, the final R = 0.0515 and wR = 0.1172 for 5712 observed reflections with I 〉 2σ（I）. X-ray crystal structure analysis suggests that compound [CH2（C7H5O2）4（C2H6O）2] has a binuclear structure with two Cu（II） atoms coordinated by four benzoate groups and two ethanol molecules. The crystal packing is stabilized by intermolecular O-H...O hydrogen bonds. The compound inhibits the proliferation of K562 cells （chronic myeloid leukemic cells） significantly and dose-dependently in 48 h, and IC50 of K562 is 17.3μg/mL by trypan blue dye exclusion method.展开更多
