摘 要:It has previously been shown that Dendrostellera lessertii(Thymelaeaceae)has stronganticancer *** this study,the antileukemic activity of another new compound from the same plantextract is ***(NB4 and HL-60)and erythroleukemia(K562)cells were cultured in thepresence of various concentrations of the new compound(0.5-3.0 μtg/ml)for *** cell numbers werethen determined by trypan blue exclusion *** new compound inhibited growth and proliferation ofNB4,HL-60 and K562 with IC50values of 1.5,2.0 and 2.5μg/ml,*** also found that the newcompound inhibited cell proliferation in a dose-and time-dependent *** low concentrations and after48h of treatment,approximately 50%-70% of NB4 and HL-60 cells were differentiated to monocyte/macrophage lineage and approximately 30%-40% of the treated K562 cells were differentiated in the mega-karyocytic lineage,as evidenced by morphological changes and nitro blue tetrazolium reduction *** of Hoechst 33258 staining also indicated that the new compound induced NB4 and HL-60 cellapoptosis at their respective IC50values after 72h of *** on the present data,the new com-pound seems a good candidate for further evaluation as an effective chemotherapeutic agent acting throughinduction of differentiation and apoptosis.
