Pregnenolone 16α-carbonitrile BiologicalActivity
| Description | Pregnenolone 16α-carbonitrile is an orally active prototypical and effective rodent-PXR activator. Pregnenolone 16α-carbonitrile, a synthetic steroid, induces cytochrome P4503A expression. Pregnenolone 16α-carbonitrile exhibits increased resistance to subsequent stressful insults[1][2][3]. |

| In Vitro | Pregnenolone 16α-carbonitrile (20 μM; 9 days) directly inhibits rat hepatic stellate cell (HSCs) transdifferentiation to a profibrogenic phenotype, although the cells did not express the PXR (in contrast with hepatocytes)[4]. |
| In Vivo | Pregnenolone 16α-carbonitrile (40 mg/kg/day; i.p.; for two days) induces the expression of Cyp3a11 and Cyp2b10 at the mRNA, protein, and enzymatic levels in WT mice[1]. Pregnenolone 16α-carbonitrile (100 mg/kg; ip; single dose) induces the expression of CYP3A mRNA in adult female Sprague-Dawley rats weighing 150-200 g[2]. Pregnenolone 16α-carbonitrile (35 mg/kg; gavage; once daily for three days) increase in Pgp expression in male Sprague-Dawley rats, aged approximately 100 days and weighing 250-400 g[3]. Animal Model: WT and Pxr-/- mice[1] Dosage: 40 mg/kg Administration: IP; per day for two days Result: Induced the expression of Cyp3a11 and Cyp2b10 at the mRNA, protein, and enzymatic levels in WT mice. Had little effect on the expression of Cyp3a11 in Pxr-/- mice |
