| Description | Pregnenolone (Arthenolone) is an endogenous steroid hormone synthesized from cholesterol, used in the treatment of Alzheimer's disease. |
| In vitro | Pregnenolone induces a large, dose-related increase of both the rate and extent of MAP2-induced tubulin assembly, whereas progesterone, inactive per se, counteracted the stimulatory effect of Pregnenolone. Pregnenolone-increased assembly of microtubules produces a completely normal structure. [1] Pregnenolone preserves microtubule abundance and promotes cell movement during epiboly. [2] Pregnenolone results in dramatic reduction in GR nuclear localization in mouse hippocampal cell line (HT-22). Pregnenolone has neuroprotective effects against both glutamate and amyloid beta protein neuropathology. [3] |
| In vivo | Pregnenolone sustains its proliferative activity in vivo and stimulates the growth of LNCaP-tumor xenografts in intact male SCID mice as well as in castrated animals. Pregnenolone is shown to activate transcription through the LNCaP androgen receptor (AR), but not the wild-type AR. [4] Pregnenolone results in a significant decrease in the accumulation of astrocytes in the proximity of the wound and in a decreased bromodeoxyuridine incorporation in reactive astrocytes of rats. [5] Pregnenolone administration results in elevations in downstream neurosteroids such as allopregnanolone, a molecule with neuroprotective effects that also increases neurogenesis, decreases apoptosis and inflammation, modulates the hypothalamic-pituitary-adrenal axis, and markedly increases GABA(A) receptor responses. Pregnenolone administration elevates pregnenolone sulfate, a neurosteroid that positively modulates NMDA receptors. [6] |

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, and a total of 10 animals are to be administered, using a formulation of 
10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH2O , the resulting working solution concentration would be 2 mg/mL.Dissolve 2 mg of the compound in 100 μL DMSO to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
1) Add 100 μL of the DMSO stock solution to 400 µL PEG300 and mix thoroughly until the solution becomes clear.
2) Add 50 µL Tween 80 and mix well until fully clarified.
3) Add 450 µL Saline,PBS or ddH2O and mix thoroughly until a homogeneous solution is obtained.
