Incubation of [16,16,19-2H3][19-3H]-19-oxoandrost-4-ene-3,17-dione (2a) with microsomal aromatase gave inter alia[16,16-2H2]-10β-hydroxyestr-4-ene-3,17-dione (1), whose analogue (1b) on incubation with the aromatase gave 10β, 17β-dihydroxyestr-4-en-3-one (1d)(ca. 10%) and no estrogens which would indicate that (1b) is not an obligatory estrogen precursor.
的[16,16,19-孵育2 ħ 3 ] [19- 3 H] -19-氧代雄甾-4-烯-3,17-二酮(2A)与微粒体芳香化酶,得到特别[16,16- 2 H ^ 2 ]-10β-hydroxyestr-4-ene-3,17-dione(1),与芳香化酶温育后的类似物(1b)得到10β,17β-dihydroxyestr-4-en-3-one(1d)(约10 %),没有雌激素,这表明(1b)不是必需的雌激素前体。
