  Suppressing aggressive behavior with analogs of allopregnanolone (epalon)

  摘要：

  3 alpha -Hydroxy-20-oxo-5 alpha -pregnan-21-yl hemisuccinate (8) was produced by partial acylation of 3 alpha ,21-dihydroxy-5 alpha -pregnan-20-one (14). 3 alpha -Fluoro-5 alpha -pregnan-20-one (9) was prepared by treatment of 3 beta -hydroxy-5 alpha -pregnan-20-one (11) with DAST and by solvolysis of tosylate 12 with tetrabutylammonium fluoride. A behavioral test on mice was performed using 3 alpha -hydroxy-5 alpha -pregnan-20-one (1) and compounds 8 and 9. Compound 8 was found to be inactive, while the fluoro derivative 9 selectively reduced aggressive behavior in mice more than the corresponding 3 alpha -hydroxy compound 1; locomotion and other behavioral features were not affected.

  Certain 3 alpha-hydroxy steroids have recently been shown to bind to the gamma-aminobutyric acid (GABA) receptor gated chloride ion channel with high affinity and to potentiate the inhibitory effects of GABA when measured both in vitro and in vivo. In the present study, a series of natural and synthetic 3 alpha-hydroxy steroids were tested for their ability to potentiate GABA-receptor-mediated chloride

  最近已显示某些3α-羟基类固醇以高亲和力与γ-氨基丁酸（GABA）受体门控的氯离子通道结合，并在体外和体内测量时均能增强GABA的抑制作用。在本研究中，测试了一系列天然和合成的3α-羟基类固醇增强GABA受体介导的氯离子（Cl-）摄入大脑皮层突触神经小体的能力。天然代谢产物3α-羟基-5α-pregnan-20-one（allopregnanolone）和3 alpha，21-dihydroxy-5α-pregnan-20-one（allotetrahydroDOC）被发现在增加GABAA-中最活跃。受体介导的Cl摄取。具有5β-孕烷构型的相应异构体的药理活性降低，部分但不是全部降低，侧链的修饰。这些类固醇增强muscimol刺激的Cl吸收的能力由于在C3处乙酰化，在C9（11）处引入不饱和度，转化为3β-羟基异构体或在C17处构型转化而丧失。据报道，一种简便的方法可以合成未标记和tri标
