biochanin A (4) compounds and their analogues were synthesized from phloroglucinol. The structures of all the synthesized compounds were established by the combined use of , , IR spectral data, and mass spectrometry; their antioxidantactivities were investigated. Most of the synthesized compounds show moderate-to-high activity; only two compounds exhibit no significant activity.
从间苯三酚合成了一系列天然存在的染料木黄酮 (3) 和 biochanin A (4) 化合物及其类似物。所有合成化合物的结构均由 、 、红外光谱数据和质谱联用确定;研究了它们的抗氧化活性。大多数合成的化合物表现出中到高的活性;只有两种化合物没有显着的活性。

methods for the synthesis of hydroxylated isoflavones were reported during the past fifty years, none is suitable for the preparation of isoflavones containing 5,7-dihydroxyl functions. This paper reports a simple, large scale preparation of 5,7-dihydroxy-3-(4-nitrophenyl)-4H-1-benzopyran-4-one (2a) by the condensation of the readily available 4-nitrobenzyl 2,4,6-trihydroxyphenyl ketone (1a) and acetic-formic
尽管在过去的五十年中已经报道了几种合成方法来合成羟基化的异黄酮,但没有一种方法适合于制备具有5,7-二羟基官能团的异黄酮。本文报告了一种简单的大规模制备5,7-二羟基-3-(4-硝基苯基)-4 H -1-苯并吡喃-4-酮(2a)的方法,该方法是通过将现成的4-硝基苄基2,4缩合1,6-三羟苯基酮(1a)和乙甲酸酐的收率很高。类似异黄酮,如7-羟基-3-(4-硝基苯基)-4- ħ -1-苯并吡喃-4-酮(2B)也可在类似的方式良好的产率获得。

We report the preparation and antiparasitic activity in vitro and in vivo of a series of isoflavone derivatives related to genistein. These analogues retain the 5,7-dihydroxyisoflavone core of genistein: direct genistein analogues (2-H isoflavones), 2-carboethoxy isoflavones, and the precursor deoxybenzoins were all evaluated. Excellent in vitro activity against Cryptosporidium parvum was observed for both classes of isoflavones in cell cultures, and the lead compound 19, RM6427, shows high in vivo efficacy against an experimental infection.
