    25R-3 beta-Hydroxy-5 alpha-spirostan-12-one (hecogenin) and 11 alpha-hydroxypregn-4-ene-3,20-dione (11 alpha-hydroxyprogesterone) were used as starting materials for the synthesis of a series of 11- and 12-substituted derivatives of 5 xi-pregnanolone (3 alpha-hydroxy-5 alpha-pregnan-20-one and 3 alpha-hydroxy-5 beta-pregnan-20-one), the principal neurosteroid acting via gamma-aminobutyric acid (GABA). These analogues were designed to study the structural requirements of the corresponding GABA(A) receptor. Their biological activity was measured by in vitro test with [H-3]flunitrazepam as radio-ligand in which allopregnanolone and its active analogues stimulated the binding to the GABA(A) receptor. Analysis of the SAR data suggests dependence of the flunitrazepam binding activity on the hydrophobic-hydrophilic balance of the groups at the C-ring edge rather than on specific interactions between them and the receptor.
