  Neurosteroid analogues. Part 13: Synthetic methods for the preparation of 2β-hydroxygonane derivatives as structural mimics of ent-3α-hydroxysteroid modulators of GABAA receptors

  摘要：

  Many different 3 alpha-hydroxysteroids in the androstane and pregnane steroid series enhance the actions of gamma-aminobutyric acid (GABA) at GABA type-A (GABA(A)) receptors in the mammalian central nervous system. Recent studies have shown that (3 alpha,5 alpha)-3-hydroxy-androstan-17- one (androsterone) is less active at these receptors than its enantiomer ent-androsterone. Further structure-activity relationship (SAR) studies are needed to explore the structural features of ent-androsterone that are important for its enhanced action at these receptors. Molecular modeling shows that 2 beta-hydroxysteroids are similar in three-dimensional shape to the enantiomers of 3 alpha-hydroxysteroids. The development of synthetic methods to gain access to C-17-substituted analogues of 2 beta-hydroxygonanes for SAR studies is demonstrated with the synthesis of (2 beta,5 alpha,14 beta)-2-hydroxygonan-17-one.
