Compounds 9 and 11 were isolated from S. divaricate for the first time. The chromon derivatives -(1-6) were evaluated for their cytotoxic activity against HL-60 human promyclocytic leukemia cells. Compound 1 (3'-O-angeloylhamaudol) showed the most potent cytotoxic activity with an IC₅₀ value of 4.41 μM and was found to induce apoptotic cell death in HL-60 cells. The loss of mitochondrial membrane potential, release of cytochrome c into the cytoplasm, and activation of caspase-9 in the 1-treated HL-60 cells suggests that I induces apoptosis through the mitochondial-dependent apoptotic pathway. | | Planta Med . 2011 Sep;77(13):1531-1535. | | Intestinal permeability of the constituents from the roots of Saposhnikovia divaricata in the human Caco-2 cell monolayer model[Pubmed: 21308612] | | The bidirectional intestinal permeability of the active constituents from the roots of Saposhnikovia divaricata, including four coumarins, anomalin (1), 5-methoxy-7-(3,3-dimethylallyloxy)coumarin (2), decursin (3), and decursinol angelate (4), as well as four chromones, cimifugin (5), prim-O-glucosylcimifugin (6), 3'- O-angeloylhamaudol (7), and sec-O-glucosylhamaudol (8), was studied by using the Caco-2 cell monolayer. These compounds were assayed by HPLC, and their transport parameters, including apparent permeability coefficients (P(app)), were then calculated. The bidirectional P(app) values of the compounds were compared with those of the markers, propranolol and atenolol. Compounds 1-5 and 7 were assigned to well-absorbed compounds, while 6 and 8 were assigned to moderately absorbed compounds. The transport of 1-7 increased linearly as a function of time up to 180 min and concentration within the test range of 10-200 μM, thus their passive diffusion mechanism was proposed. The results provided some useful information for predicting the intestinal absorption in vivo of these compounds. |
