Abstract The acid-catalyzed dehydration and rearrangement of three 17β-hydroxy-17α-methyl steroids to 17,17-dimethyl-Δ 13 -steroids is described. One of the rearranged compounds, 17,17-dimethyl-Δ 4,13 -gonadien-3-one (V), which had been previously unreported was examined in detail for hormonal and anti-hormonal activity. It proved to be less than 1/2000th as active as estrone by subcutaneous injection
摘要 描述了三种 17β-羟基-17α-甲基类
固醇在酸催化下脱
水和重排为 17,17-二甲基-Δ 13 - 类
固醇的过程。其中一种重排化合物 17,17-二甲基-Δ 4,13 -gonadien-3-one (V) 之前未报道过,详细检查了其激素和抗激素活性。在未成熟的雌性小鼠中进行皮下注射,证明其活性低于
雌酮的 1/2000,并且在通过注射或管饲给药时显示出显着的抗
雌激素活性。基于其抑制精囊
睾酮刺激的能力,它在去势小鼠中也是一种有效的抗雄激素。V 的环 A
酚类类似物 (VII) 先前在文献中报道为 10 Δ 16 - 化合物已显示为 17,17-二甲基-1,3,5(10),
