10058-F4 inhibits the growth of leukemic cells and dimerization of the c-Myc/Max heterodimerization to control the cell proliferation, apoptosis, and differentiation, and its aberrant expression. 10058-F4 increased FOXO1 mRNA in MedB-1 cells. 10058-F4 is most efficient in inducing neuronal differentiation and lipid accumulation in MYCN-amplified neuroblastoma cells. 10058-F4 could markedly suppresse the wild-type LKB1 loss-induced cell invasiveness. 10058-F4 increased the chemosensitivity of HepG2 cells to low-dose doxorubicin, 5-fluorouracil and cisplatin.
|Cell lines||PC-3 and DU145 cells|
|Preparation method||MTT assay
PC-3 cells (2 × 104 cells in logarithmic growth) were plated into 96-well culture plates and allowed to adhere to the plates for 24 h prior to the addition of 10058-F4 in medium containing 1% ethanol such that the final concentrations in the wells were 0.1-100 μM in medium containing 0.3% ethanol. After 72 h, 50 μl of 1 mg/ml MTT was added to each well. The cells were washed with medium and phosphate buffered saline, and 150 μl of DMSO was added to each well, followed by shaking for 5 min. The absorbance at 570 nm was read on DYNEX MRX Revelation microplate reader (Dynex, Vienna, VA, USA). Results were compared to wells containing cells treated with vehicle alone and were expressed as % inhibition. The IC50 was calculated using the Hill equation, the program ADAPT II, and data from three separate experiments.
|Incubation time||72 h|
|Animal models||SCID mice bearing DU145 or PC-3 xenografts|
|Formulation||cremophor EL:ethanol:saline (1:1:8 v/v/v) at a final concentration of 2 or 3 mg/ml|
|Dosages||20 or 30 mg/kg daily for 5 days for 2 weeks|
|Body Surface Area (m2)||0.007||0.025||0.15||0.05||0.02||0.5|
|Animal A (mg/kg) = Animal B (mg/kg) multiplied by||Animal B Km|
|Animal A Km|
For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
|Solubility||DMSO 40 mg/mL|
