| Description | Ipriflavone, a derivative of isoflavone, is a calcium metabolism regulator useful in thetreatment of primary and secondary osteoporosis, as well as disorders of osteogenesis. Itappears to be without significant side-effects. |
| Chemical Properties | white powder |
| Originator | Chinoin (Japan) |
| Uses | 7-Isopropoxy-3-phenyl-4H-1-benzopyran-4-one (Ipriflavone) has been used as a model drug in a study to functionalize the mesoporous bioactive glasses (MBG). Study suggested that since ipriflavone is a hydrophobic anti-osteoporotic drug, it easily attaches to the surface of MBG and results in long-term drug delivery. |
| Uses | anabolic |
| Definition | ChEBI: Ipriflavone is a member of the class of isoflavones that is isoflavone in which the hydrogen at position 7 is replaced by an isopropoxy group. A synthetic isoflavone, it was formerly used for the treatment of osteoporosis, although a randomised controlled study failed to show any benefit. It is still used to prevent osteoporosis in post-menopausal women. It has a role as a bone density conservation agent. It is a member of isoflavones and an aromatic ether. |
| Brand name | Osten |
| benefits | Ipriflavone is used clinically to treat osteoporosis. Bodybuilders also use ipriflavone, but enough experimental data supports this purpose. It has been shown to have anti-inflammatory and antioxidant activity. It helps to reduce bone loss, increase bone density, and reduce the risk of developing osteoporosis. It has also been found to help reduce neuroinflammation . In addition, it has been found to help reduce the risk of certain types of cancer, improve cognitive function and reduce the risk of depression. |
| General Description | 7-Isopropoxy-3-phenyl-4H-1-benzopyran-4-one (Ipriflavone), a synthetic flavonoid, is reported to stimulate the activity of osteoblasts. It is reported to promote the deposition of calcium and the formation of mineralized nodules by newborn rat calvarial osteoblast-like (ROB) cells as well as the activity of alkaline phosphatase. Ipriflavone, an isoflavone derivative, is a new drug used to decrease bone loss in osteoporosis. |
| Side effects | Ipriflavone should be taken under medical supervision only. It can produce side effects such as stomach pain, diarrhoea, dizziness, etc. It may have a sudden increase in the WBC count if administered for six months or more. When the treatment with Ipriflavone is on, it is suggested that the WBC count should be monitored. |
| Synthesis | 13057-72-2 75-26-3 35212-22-7 General procedure for the synthesis of epoxyflavone from 7-hydroxy-3-phenyl-4H-benzopyran-4-one and 2-bromopropane: To a 30 ml DMF solution of 2.50 g of 7-hydroxy-3-phenyl-4H-benzopyran-4-one (10.5 mmol) was added 1.80 g of anhydrous K2CO3 (13.0 mmol) and 3.0 ml of 2-bromopropane ( 32.0 mmol). The reaction mixture was stirred at 80 °C for 4 h. After completion of the reaction, the mixture was poured into ice water. The precipitate was collected by filtration and washed with a small amount of water and dried to give the crude product. The crude product was purified by Sephadex LH-20 column chromatography (eluent: chloroform:methanol = 7:3), and the fraction containing the target product was collected, concentrated, and recrystallized from acetone to give 1.05 g of epsilon-flavonoid crystals with a yield of 42% (w/w) and a melting point of 110-111 °C. The product structure was determined by 1H NMR. The structure of the product was confirmed by 1H NMR, 13C NMR and mass spectrometry (MS).1H NMR (DMSO-d6) δ: 1.33 (-CH3), 1.34 (-CH3), 4.86 (m, 1H, >CH2-), 7.05 (dd, 1H, J = 8.86, 2.20 Hz, 6-H), 7.16 (d, 1H, J = 2.50 Hz, 8-H), 7.38 (t, 1H, J = 6.78 Hz, 4'-H), 7.44 (t, 2H, J = 7.76, 1.6 Hz, 3',5'-H), 7.59 (d, 2H, J = 8.09, 1.6 Hz, 2',6'-H), 8.22 (d, 1H, J = 8.86 Hz, 5-H), 8.46 (s, 1H 128.1 (C-3',5'), 128.9 (C-2',6'), 132.0 (C-4'), 154.0 (C-2), 157.5 (C-9), 162.0 (C-7), 174.1 (C-4). , 279.5 (M-H)-. Elemental analysis (C18H16O3) calculated values: C, 77.12; H, 5.75. measured values: C, 76.50; H, 5.69. |
| 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. 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. |
| in vivo | Ipriflavone ameliorated the host inflammatory response associated with activation of NLRP3 inflammasomes at the implantation site, which was characterised by inflammatory cell infiltration and reduced levels of the pro-inflammatory cytokine interleukin-1β. 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-month treatment with ipriflavone increases bone density and improves the biomechanical properties of adult rat male bones without altering mineral composition. |
