  • Metabolic 5-methyl-isoflavone-derivatives, process for the preparation thereof and compositions containing the same
    Patent number: 4163746
    Abstract: Nonestrogenic 5-methyl-alkoxy-isoflavone, namely, 5-methyl-7-methoxy-isoflavone, 5-methyl-7-ethoxy-isoflavone, 5-methyl-7-isopropoxy-isoflavone, and 5-methyl-7-(2-hydroxy-ethoxy)-isoflavone are useful as weight-gain promoters in feeds from which the 7-methoxy and 7-ethoxy isoflavones have been excluded because of estrogenic effects. They are more effective than 7-isopropoxy-isoflavone as well.
