چکیده
the dried plant was extracted with dichloromethane and after defatting with hexane, transferred repeatedly on silica columns using dichloromethane-hexane and ethyl acetate-hexane as mobile phases. finally the fractions were purified by high performance liquid chromatography using a pack-sil column and hexane: ethyl acetate as mobile phase. the structures of the isolated compounds included: cycloart-25-ene-3β, 24-diol (1), cycloart-23(z)-ene-3β, 25-diol (2), cycloart-23(e)-ene-3β, 25-diol (3), and 24-methylene-cycloart-3β-ol (4) were elucidated by 13c- and 1h-nmr as well as ir and by the aid of mass fragmentation pattern and comparing with the literature. the biological effects of the compounds were done by the mtt assay on two different cancer cell lines including mda-mb48 and mcf-7. among these compounds, cycloart-23(e)-ene-3β,25-diol (3) was the most active compound on mda-mb468 cell line (ld50 = 2.05 μgml-1 ) and cycloart-23(z)-ene-3β, 25-diol (2) was the most active compound on mcf-7 cell line (ld50 = 5.4 μgml-1).

متن کاملCell Kinetic Study of Tamoxifen Treated MCF-7 and MDA-MB 468 Breast Cancer Cell Lines
Apoptosis could be a major mechanism of antitumor effect of tamoxifen. Therefore this study is designed to characterize the kinetic behavior of tamoxifen-induced apoptosis in the estrogen receptor positive (ER+) and negative (ER-) cell lines, MCF-7 and MDA-MB-468. Frequency of cell death was examined by trypan blue and acridine orange staining. Annexin V-Fluorescein/PI was used in flow cytometr...
