Dependence of channel activation on voltage and pregnenolone sulfate concentration.

open access: yes, 2019
(A) Channel open probability was measured as a function of membrane potential. Cytoplasmic solutions contained 0.1 μM free Ca2+. The pipette contained pregnenolone sulfate (0 μM to 75 μM as indicated) dissolved in an external solution that also contained

Microbial Hydroxylation of Pregnenolone Derivatives

open access: yesChemical and Pharmaceutical Bulletin, 2005
Pregnenolone and pregnenolone acetate were incubated with the fungi Cunninghamella elegans, Rhizopus stolonifer and Gibberella fujikuroi. Incubation of with C. elegans yielded metabolites, 3beta,7beta,11alpha-trihydroxypreg-5-en-20-one, 3beta,6alpha,11alpha,12beta,15beta-pentahydroxypreg-4-en-20-one and 3beta,6beta,11alpha-trihydroxypreg-4-en-20-one ...

Neuroactive steroids in depression and anxiety disorders: Clinical studies [PDF]

open access: yes, 2006
Certain neuroactive steroids modulate ligand-gated ion channels via non-genomic mechanisms. Especially 3 alpha-reduced pregnane steroids are potent positive allosteric modulators of the gamma-aminobutyric acid type A (GABA(A)) receptor.
