dendrostellera lessertii (thymelaeaceae) is a toxic plant that grows in parts of iran. the anti-proliferative properties of its crude methanol extract and one of its active components, 3-hydrogenkwadaphnin (3-hk), have been established using several cancer cell lines. methods: in a further attempt to determine the mode of action, two groups of synchronously growing cells were treated with a sin...

3-Hydrogenkwadaphnin (3-HK) is a daphnane-type diterpene ester isolated from Dendrostellera lessertii (Thymelaeaceae) with high differentiation and apoptotic potency in leukemic cells without any measurable adverse effects on normal cells (Moosavi et al., 2005b). In this study, we report that 3-HK (12 nM) has the ability to cease proliferation, induce differentiation and apoptosis in chronic my...

Recently, we have reported that 3-hydrogenkwadaphnin (3-HK), a diterpene ester isolated from Dendrostellera lessertii (Thymealeaceae), is very effective against leukemia cell lines without any detectable effects on normal cells (Moosavi et al., 2005b). In this study, we report that 3-HK induces G1 cell-cycle arrest, differentiation and apoptosis in APL NB4 cell line. Indeed, the drug between 24...

3-Hydrogenkwadaphnin (3-HK) is a new diterpene ester, recently isolated from the leaves of Dendrostellera lessertii with potent anti-tumoral and anti-metastatic activities. Herein, we report that 3-HK induces differentiation and apoptosis in HL-60 cells. The drug at 2.5 - 40 nM inhibited proliferation of HL-60 cells after 24 - 96 h of treatment. Cell viability was also decreased by 57 % after 9...
