In vitro study | Ipriflavone can regulate the differentiation and biosynthesis properties of human bone marrow stromal osteoprogenitor cells (BMC) by enhancing the expression of certain important matrix proteins and promoting the mineralization process. Treatment with Ipriflavone at a dose of 10 μm significantly inhibited glycosylation end product (AGE) enhanced bone resorption in cultured mouse undifferentiated bone cells. In addition, Ipriflavone treatment was able to effectively enhance calcium absorption by duodenal cells. Ipriflavone dose-dependently inhibited proliferation and DNA synthesis of MDA-231 cells and blocked ligand-induced phosphorylation of Tyr845 in EGFR. Treatment with Ipriflavone at a dose of 50 μm did not cause apoptosis of MDA-231 cells. |
In vivo study | For bone metastases, Ipriflavone, administered orally at a dose of 12 mg instead of 6 mg, significantly inhibits the development of new osteolytic bone metastases of MDA-231 cells and inhibits the progression of established osteolytic lesions, and reduce the number of osteoclasts adjacent to cancer cells. Consistent with in vitro activity, Ipriflavone treatment at doses of 6 or 12 mg/kg significantly inhibited tumor growth in MDA-231 xenografts compared to untreated mice, the treated mice were reduced by 25% and 45% in volume and 47% and 63% in weight, respectively, and the life span of tumor-bearing mice was prolonged. LD50: mice> 2.5 g/kg (intraperitoneal injection),>5 g/kg (subcutaneous injection),>10 g/kg (Gavage); rats> 2.5 g/kg (intraperitoneal injection),>5 g/kg (subcutaneous injection),>10 g/kg (Gavage) |

anhydrous zinc chloride was dissolved in anhydrous ether and resorcinol was added. With stirring and cooling in an ice bath, dry hydrogen chloride gas was introduced to saturation, and phenylacetonitrile was added slowly with stirring, and then hydrogen chloride was passed through and allowed to stand. The upper ether layer was poured off, hydrochloric acid was added, and the mixture was stirred for a while. After standing, the upper layer of acid solution was decanted, water was added, and the mixture was stirred and refluxed. Cool with vigorous stirring until the oil is completely converted to solid particles. Drying gave the compound. The obtained compound, anhydrous potassium carbonate, 2-Bromopropane and dimethylformamide were stirred at 110 ° C., and the obtained compound, triethyl orthoformate, morpholine, glacial acetic acid and dimethylformamide were reacted by heating with stirring. The obtained crude product was recrystallized with ethanol to obtain ipriflavone.
