英文摘要bisphenol a (bpa), the important endocrine-disrupting chemical (edc), has been reported to be able to induce various toxicity. the present study aims to understand the toxicity behavior of bisphenol a through evaluating the inhibition profile of bisphenol a towards udp-glucuronosyltransferase (ugt) isoforms. in vitro recombinant ugts-catalyzed 4-methylumbelliferone (4-mu) glucuronidation reaction was employed as probe reaction for all the tested ugt isoforms. the results showed that bisphenol a exerted stronger inhibition towards ugt2b isoforms than ugt1a isoforms. furthermore, the inhibition kinetic type and parameters (k-i) were determined for the inhibition of bisphenol a towards ugt2b4, 2b7, 2b15, and 2b17. bisphenol a exhibited the competitive inhibition towards ugt2b4, and noncompetitive inhibition towards ugt2b7, 2b15 and 2b17. the inhibition kinetic parameters (k-i) were calculated to be 1.1, 32.6, 5.6, and 19.9 mu m for ugt2b4, 2b7, 2b15 and 2b17, respectively. in combination with the in vivo concentration of bisphenol a, the elevation of exposure dose was predicted to increase by 29.1%, 1%, 5.7%, and 1.6% for ugt2b4, 2b7, 2b15, and 2b17, indicating the high influence of bisphenol a towards the in vivo ugt2b isofroms-mediated metabolism of xenobiotics and endogenous substances. all these data provide the supporting information for deeper understanding of toxicology of bisphenol a.
