Product inhibition of UDP-glucuronosyltransferase (UGT) enzymes by UDP obfuscates the inhibitory effects of UGT substrates.
Substrates that are specific for certain UDP-glucuronosyltransferase (UGT) isoforms are usually used as specific inhibitors to identify UGT isoforms responsible for the glucuronidation of drugs. 1-Naphthol and 4-nitrophenol are probe substrates for human UGT1A6. In the present study, we found that UGT1A1-catalyzed estradiol 3-O-glucuronide formation and UGT1A4-catalyzed imipramine N-glucuronide...
متن کاملInhibitory Effect of Sauchinone on UDP-Glucuronosyltransferase (UGT) 2B7 Activity.
Herb-drug interaction (HDI) limits clinical application of herbs and drugs, and inhibition of herbs towards uridine diphosphate (UDP)-glucuronosyltransferases (UGTs) has gained attention as one of the important reasons to cause HDIs. Sauchinone, an active lignan isolated from aerial parts of Saururus chinensis (Saururacease), possesses anti-oxidant, anti-inflammatory, and anti-viral activities....
متن کاملGenotyping of the UDP-glucuronosyltransferase (UGT) 1A7 gene revisited.
Readers are encouraged to write letters to the editor concerning articles that have been published in GASTROENTEROLOGY. Letters that include original, unpublished data will not be considered. Letters should be typewritten and submitted electronically to In 2001 and in 2003, we published 2 studies reporting the role of single nucleotide polymorphisms (SNPs) of the mu-tagen detoxifying UDP glucur...
متن کاملQuantitative analysis of UDP-glucuronosyltransferase (UGT) 1A and UGT2B expression levels in human livers.
UDP-glucuronosyltransferases (UGTs) catalyze glucuronidation of a variety of xenobiotics and endobiotics. UGTs are divided into two families, UGT1 and UGT2. The purpose of this study was to estimate the absolute expression levels of each UGT isoform in human liver and to evaluate the interindividual variability. Real-time reverse transcriptase-polymerase chain reaction analysis was performed to...
متن کاملATP serves as an endogenous inhibitor of UDP-glucuronosyltransferase (UGT): a new insight into the latency of UGT.
We have suggested that adenine-related compounds are allosteric inhibitors of UGT in rat liver microsomes (RLM) treated with detergent. To clarify whether the same occurs with a pore-forming peptide, alamethicin, the effects of adenine-related compounds on 4-metylumbelliferone (4-MU) glucuronidation were examined using RLM and human liver microsomes (HLM). ATP inhibited 4-MU glucuronidation whe...
