General description

Pregnenolone is present in adrenal gland, gonads and placenta and is synthesized form cholesterol in the presence of mitochondrial enzyme, cytochrome P450 family 11 subfamily A member 1(CYP11A1).
Pregnenolone is a steroid hormone precursor. It is produced from cholesterol in the steroidogenic tissues, like adrenal gland, gonads and placenta.

Application

Pregnenolone is suitable for use as a steroid standard.

Biochem/physiol Actions

Pregnenolone and its derivatives pregnenolone sulfate and allopregnenolone enhance the memory and alleviate depression improving brain cognitive functions. Pregnenolone inhibits cannabinoid receptor and associated pathway and elicits protective function during cannabis intoxication. It plays neuroprotective role in Alzheimer′s disease(AD), schizophrenia and multiple sclerosis. Pregnenolone is a neurosteroid with memory-enhancing property. It modulates excitatory glutamatergic N-Methyl-D-aspartate (NMDA) and γ-aminobutyric acid type A receptors.
Pregnenolone serves as a precursor (inactive) for steroid hormones. Pregnenolone is involved in the synthesis of neurosteroids in the brain and its active form exists as a sulfate derivative. The complex of adrenodoxin reductase (AdR), adrenodoxin (Adx) and P450scc (P450 side chain cleavage) enzymes, mediate the conversion of cholesterol to pregnenolone in mitochondria. Pregnenolone acts as an antagonist for type-1 cannabinoid (CB1) receptor.
It stimulates immunosuppression. Pregnenolone also has anti-inflammatory and antifatigability properties.
