Fourteen of the compounds studied inhibited both bilirubin and estradiol glucuronidation (Table 1). Among these 14 compounds, ritonavir, anthraflavic acid, levothyroxine, riluzole, baicalein, farnesol, 4′-OH-phenytoin, 4-methylumbelliferone, raltegravir, and 1-naphthol exhibited very similar IC50 values (differences less than 2-fold) on both bilirubin glucuronidation and estradiol-3-glucuronidation (Table 1). Ketoconazole, carvedilol, and niflumic acid exhibited more disparity with respect to inhibition of the two reactions in that these compounds exhibited at least a 2-fold higher IC50 value against bilirubin glucuronidation than against estradiol-3-glucuronidation. SN-38 only weakly inhibited bilirubin glucuronidation (IC50 = 356 μM) and seemed to be a partial inhibitor of estradiol-3-glucuronidation. |

This study indicates that hepatocyte nuclear factor 1alpha (HNF1alpha) bound to the proximal promoter motif not only enhances the basal reporter activity of UGT1A1, including the distal (-3570/-3180) and proximal (-165/-1) regions, but also influences the transcriptional regulation of UGT1A1 by CAR, PXR, GR, and AhR to markedly enhance reporter activities. |

Human UDP-glucuronosyltransferase (UGT)1A1 is a critical enzyme responsible for detoxification and metabolism of endogenous and exogenous lipophilic compounds, such as potentially neurotoxic bilirubin and the anticancer drug irinotecan SN-38, via conjugation with glucuronic acid. A 290-bp distal enhancer module, phenobarbital-responsive enhancer module of UGT1A1 (gtPBREM), fully accounts for constitutive androstane receptor (CAR)-, pregnane X receptor (PXR)-, glucocorticoid receptor (GR)-, and aryl hydrocarbon receptor (AhR)-mediated activation of the UGT1A1 gene. |
