生物活性

Ipriflavone is a synthetic isoflavone derivative used to suppress bone resorption.

体外研究
(In Vitro)

Ipriflavone inhibits the proliferation and DNA synthesis of MDA-231 cells and blocks the ligand-induced phosphorylation of Tyr(845) of the EGFR. Ipriflavone does not promote apoptosis of MDA-231 cells[1]. Ipriflavone also promotes the deposition of calcium and the formation of mineralized nodules by newborn rat calvarial osteoblast-like cells as well as the activity of alkaline phosphatase[2].

体内研究
(In Vivo)

Daily oral administration of ipriflavone at 12 mg/mouse significantly inhibits the development of new osteolytic bone metastases and the progression of established osteolytic lesions, prolonging the life of tumor-bearing mice. Ipriflavone reduces the number of osteoclasts at the bone-cancer interface with no severe adverse effects on the host[1]. 1-month treatment with ipriflavone increases bone density and improves the biomechanical properties of adult rat male bones without altering mineral composition[3]

Cell Assay
[1]

Ipriflavone is dissolved in absolute ethanol and added to the medium at 1-50 μM. The final ethanol concentrations are <0.5% (v/v). MDA-231 cells are seeded in 35 mm culture dishes in DMEM supplemented with 10% FBS in the presence of ipriflavone (1, 10 or 50 μM) or ethanol. After 48 hr incubation, the medium is changed with fresh medium containing the same concentrations of ipriflavone or ethanol. After incubation for 24, 48, 72 and 96 hr from the initial seeding, cells are treated with trypan blue to estimate the number of viable cells[1].

Animal Administration
[1][3]

Rats: To assess the potential impact of ipriflavone on the biomechanical properties and mineral composition of bone, adult male rats are orally administered two doses (200 or 400 mg/kg bw) of ipriflavone for 1 month. Bone biomechanics are evaluated by vibration damping, an index of strain energy loss, and impact strength[3]. Mice: Ipriflavone is suspended in water containing 0.5% (w/v) methylcellulose and given to mice orally at 6 or 12 mg/0.2 mL daily, which is equivalent to 200 or 400 mg/kg body weight. MDA-231 cells are injected s.c. into the interscapular space of nude mice (on day 0), which are then given ipriflavone (6 or 12 mg/mouse) or the methylcellulose solution orally from day 1 to day 27. Tumor growth is analyzed twice a week by measuring the tumor volume[1].
