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.

How to use
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).
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. 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. 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.
