Microbial Hydroxylation of Pregnenolone Derivatives
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 ...

Pregnenolone decreased the effect of Henkel 100-induced responses in the OE.
(A) Representative submerged EOG responses to Henkel 100 (1:5,000) were recorded from the surface of the septum of female mice. Pregnenolone preincubation (1 μM) temporarily reduced the response amplitude.
