Isoflavones are modified by esterification at one or more of the C4′, C5, C6, and C7 positions to promote bioavailability, and especially to enhance solubility over the corresponding unesterified isoflavones. Preferred modifications produce a carboxylic acid hemiester or a phosphate ester which is biologically hyrolyzable. Preferred starting isoflavones are genistin and daidzin, and still more preferably comprises an aglycone form such as genistein or daidzein. Esterified isoflavones may be employed therapeutically or prophylactically for a variety of conditions, provided as a dietary supplement, or added to natural or processed food-stuffs.
异黄酮通过在C4'、C5、C6和C7位置中的一个或多个位置进行酯化修饰,以促进生物利用度,特别是提高其溶解度,相较于对应的未酯化异黄酮。首选的修饰产生一个羧酸半酯或磷酸酯,这些酯在生物上可水解。首选的起始异黄酮是根黄素和黛黄素,更好的是包括一种裸醣形式,如根黄素或黛黄素。酯化的异黄酮可以在治疗或预防各种疾病时使用,作为膳食补充剂提供,或添加到天然或加工食品中。
