Pyributicarb, a carbamate-type herbicide, is a potent activator of both CYP3A4 gene and human pregnane X receptor (hPXR).
Pyributicarb, a carbamate-type herbicide, is a potent activator of both CYP3A4 gene and human pregnane X receptor (hPXR). Pyributicarb is found to increase the CYP3A4 reporter activity at 0.1 to 1 μM more strongly than typical CYP3A4 inducer rifampicin. Expression of hPXR-siRNA clearly diminishes the Pyributicarb-stimulated CYP3A4 reporter activity in 3-1-10 cells and decreases the endogenous CYP3A4 mRNA levels in HepG2 cells[1]. Pyributicarb induces luciferase transcription via hPXR at low concentrations in the order of 10 nM. The relative potency of Pyributicarb for hPXR is 8.6-fold that of rifampicin (RIF)[2].
Pyributicarb causes enhancement of CYP3A4-derived reporter activity in mouse livers introduced with hPXR by adenovirus[1].
