Two cancer cell lines (5637 and HeLa) were used for cyto-
toxic activity assays. 5637 and HeLa cells were cultured in
RPMI-1640 medium (Hyclone, Logan, UT, USA), supple-
mented with 10% fetal bovine serum (Hyclone) at 37 °C in
a humidifed atmosphere with 5% CO2. Cell viability was
determined by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphe-
nyltetrazolium bromide (MTT) assay [22]. A volume of 90
µL of adherent cells was seeded into each well of the 96-well
culture plates with initial destiny of 1× 104 cells/mL, and
cells were allowed to adhere for 24 h before addition of test
compounds. Then, test concentrations of compounds 1–11
(10 µL) were added to each well. Each cancer cell line was
then exposed to the test compounds at concentrations of 1,
5, 10, 25, 50, and 100 µM in triplicate for 24 h. After 24 h
of treatment, MTT solution (15 µL, 5 mg/mL) was added to
each well and the plates were incubated for 4 h at 37 °C. The
supernatant was then removed from formazan crystals and
DMSO (100 µL) was added to each well. The optical density
of the lysate was measured at 492 nm in a microplate reader.
Results were expressed as a percentage of the control, and
half maximal inhibitory concentration (IC50) values were
calculated. Cisplatin injection (5 mg/mL, Jiangsu Hansoh
Pharmaceutical Group Co., Ltd., Jiangsu, China) was used
as a positive control. The fnal concentration of DMSO used
to dissolve the test compounds was less than 0.1% (v/v).
