parent compounds of benzene nitrile 苯腈类母体化合物
Therefore we have selected and designed monohydroxy- isoflavones with 1-4 methoxy group(s) (2a and 2d-f), dihydroxyisoflavone (daidzein, 2b), and trihydroxyisoflavone (genistein, 2e) as the parent compounds for research.
因此我们选择和设计了分别含有一、二、三、四个甲氧基的单羟基异黄酮(2a及2d-f)、二羟基异黄酮(大豆异黄酮，2b)和三羟基异黄酮(金雀异黄酮，2c)作为研究的母体化合物。
