ABSTRACT:
A compound is provided for increasing the concentration of a parent isoflavone in a subject in vivo. The parent isoflavone has a skeletal structure including a 5 position and a 7 position, a 5 alkyl group, and a 7-hydroxy group with a 7-hydroxy oxygen appended to the 7 position and a 7-hydroxy hydrogen appended to the 7-hydroxy oxygen. The compound includes a substrate having the skeletal structure of the parent isoflavone, with a 5 position and a 7 position corresponding to the 5 and 7 positions respectively of the parent isoflavone. An alkyl group is appended to the 5 position. A promoiety is appended to the 7-hydroxy oxygen of the substrate as a substitute for the 7-hydroxy hydrogen of the parent isoflavone the promoiety and the 7-hydroxy oxygen establishing an alkylcarbonate ester. A related method also is provided.
