Associations of UGT2B7 with chemical compounds

  • PURPOSE: Ketoconazole has been shown to inhibit the glucuronidation of the UGT2B7 substrates zidovudine and lorazepam [18].
  • UGT2B7 was demonstrated to glucuronidate estrogens, catechol estrogens, and androstane-3alpha,17beta-diol more efficiently than any other human UGTB isoform [19].
  • Human uridine diphosphate-glucuronosyltransferase UGT2B7 conjugates mineralocorticoid and glucocorticoid metabolites [13].
  • For the first time, a significant difference between the two allelic variants of UGT2B7 is described, because UGT2B7H((268)) possesses an 11-fold higher aldosterone glucuronidation efficiency (ratio Vmax((app.))/Km((app.))) than UGT2B7Y((268)) [13].
  • Valproic acid inhibited UGT1A9 catalyzed propofol glucuronidation in an uncompetitive manner and UGT2B7 catalyzed AZT glucuronidation competitively (K(i)=1.6+/-0.06mM) [20].
  • Both UGT2B7 polymorphisms and co-medications significantly influenced AcMPAG production, but cyclosporin and tacrolimus hindered the phenotypic impact of this trait [21].

Physical interactions of UGT2B7


Enzymatic interactions of UGT2B7


Regulatory relationships of UGT2B7

  • Addition of CYP3A4 to untreated COS microsomes expressing UGT2B7 had no or minor effects on morphine glucuronidation [23].
  • Vmax for 1A9 was fourfold higher than that measured for UGT2B7, 92 compared with 21 pmol min(-1) mg(-1), respectively, but UGT1A9 was expressed at approximately twofold higher level than the UGT2B7 in the recombinant cell lines [25].

Other interactions of UGT2B7

  • UGT2B4 demonstrates reactivity toward 5alpha-reduced androgens and catechol estrogens, but at a significantly lower level than UGT2B7, 2B15, and 2B17 [19].
  • These results imply that concomitant chronic intake of therapeutic drugs and dietary components that are UGT2B7 and/or UGT1A9 substrates may interfere with estragole metabolism [1].
  • The activity supported by UGT2B7 and UGT2B15 was very low and restricted to cis-resveratrol [26].
  • Immunoblot analysis demonstrated the presence of UGT1A6 and UGT2B7 in stomach and throughout the intestine [27].
  • Kinetic analysis showed that UGT2B7 exhibits much higher glucuronidation efficiency (Vmax/Km) with ibuprofen, ketoprofen, and others, compared to UGT1A3 [28].
