RationaleIn order to improve upon the pharmacological properties of the neuroactive steroid ganaxolone, it was used as the starting point in the design of novel neurosteroids that replace the 17β-acetyl side chain with an isoxazole bioisostere.ObjectivesUCI-50027 (3-[3α-hydroxy-3β-methyl-5α-androstan-17β-yl]-5-(hydroxymethyl)isoxazole) was designed as an orally active neuroactive steroid specifically targeted at the gamma-aminobutyric acid(A) receptor (GABAAR).MethodsUCI-50027 was tested in…

Although drug interactions depended on the constituent drugs, the combination tested, and the behavioral endpoint; a combination was identified that would be predicted to result in supra-additive anxiolytic-like effects with predominantly additive discriminative stimulus effects.

The remarkable potency of Co 152791 as a positive allosteric modulator of GABAA receptors may be explained by its interaction with an auxiliary binding pocket in the neuroactive steroid binding site and hinders metabolism of the 3alpha-hydroxy group contributing to the exceptional anticonvulsant potency of this compound relative to other neuroactive steroids.
