Pregnenolone monosulfate is a key precursor to various steroid hormones, including steroid hormones, and possesses multiple biological functions[1-2]. Pregnenolone monosulfate can be utilized in neuroscience research and related nervous system disorders[3-4].
In vitro, Pregnenolone monosulfate (5-300μM) was applied to GH3 pituitary cells for 1 minute, Pregnenolone monosulfate induced a rapid and transient increase in intracellular calcium ion ([Ca²⁺]i) levels. Pregnenolone monosulfate activated L-type voltage-gated calcium channels, mediating extracellular calcium influx[5]. In neonatal rat cerebellar Purkinje cells (P4–10), Pregnenolone monosulfate (25μM) enhanced glutamate release by promoting presynaptic calcium influx through transient receptor potential (TRP) channels, Pregnenolone monosulfate significantly increased AMPA receptor-mediated miniature excitatory postsynaptic currents (AMPA-mEPSCs)[6].
In vivo, in dopamine transporter knockout (DAT-KO) mice (8-10 weeks old), Pregnenolone monosulfate (40 or 80mg/kg; administered either as a single injection or daily for 10 consecutive days via intraperitoneal injection). Pregnenolone monosulfate significantly suppressed hyperlocomotion and stereotypic behaviors, rescued prepulse inhibition deficits, and improved cognitive impairments in novel object recognition and social food preference tests. The therapeutic effects of Pregnenolone monosulfate were mediated through the AKT/GSK3β pathway and increased expression of the hippocampal NMDA receptor NR1 subunit[7]. In wild-type mice (9-10 weeks old), a single subcutaneous injection of Pregnenolone monosulfate (6mg/kg), Pregnenolone monosulfate antagonized Δ9-tetrahydrocannabinol (THC)-induced psychotic-like behaviors, significantly blocked THC-induced cognitive impairments, sensory gating deficits, and reduced social interaction[8].

| Cell experiment [1]: | |
Cell lines | GH3 cells (rat pituitary clonal cell line) |
Preparation Method | GH3 cells were cultured as monolayers on glass coverslips in Dulbecco’s modified Eagle medium supplemented with 10% fetal bovine serum at 37°C, 5% CO₂. Cells were loaded with Fura-2/AM (5μM) for 30 min and perfused with physiological buffer. Pregnenolone monosulfate (5–300μM) was applied via perfusion for 1min. |
Reaction Conditions | 5–300μM; 1min |
Applications | Pregnenolone monosulfate induced a rapid, dose-dependent increase in intracellular Ca²⁺ ([Ca²⁺]ᵢ) in GH3 cells, with an EC₅₀ of ~32μM. The [Ca²⁺]ᵢ surge was abolished in Ca²⁺-free medium or in the presence of inorganic Ca²⁺ channel blockers (La³⁺, Co²⁺). Organic L-type voltage-gated Ca²⁺ channel (VGCC) blockers (nicardipine, D600) inhibited the response, indicating that the Ca²⁺ influx is primarily mediated through L-type VGCCs. Co-application with the VGCC agonist Bay K 8644 potentiated the effect, suggesting synergistic modulation of Ca²⁺ channels. |
| Animal experiment [2]: | |
Animal models | C57BL/6-N mice (9–10 weeks old) |
Preparation Method | Mice were subcutaneously (s.c.) administered Pregnenolone monosulfate (6mg/kg) either 10 minutes before or 30 minutes after intraperitoneal (i.p.) injection of Δ9-tetrahydrocannabinol (THC; 0.3–10mg/kg). Behavioral tests (e.g., spontaneous alternation, social interaction, prepulse inhibition, locomotion, and "reality testing") were conducted at specified time points post-THC administration (45–120 minutes). |
Dosage form | 6mg/kg; s.c.; Acute single injection. |
Applications | Pregnenolone monosulfate blocked a wide spectrum of THC-induced psychotic-like behaviors, including cognitive deficits, reduced prepulse inhibition, decreased social interaction, hyperlocomotion, and impaired "reality testing" (a measure of mental sensory representations). |
