Nicotine 167-175 UDP glucuronosyltransferase family 1 member A4 Homo sapiens 156-162 20133892-6 2010 Nicotine was found to selectively inhibit UGT2B10 but not UGT1A4 activity. Nicotine 0-8 UDP glucuronosyltransferase family 1 member A4 Homo sapiens 58-64 17909004-3 2007 In the present study, microsomes of UGT2B10-overexpressing HEK293 cells exhibited high N-glucuronidation activity against both nicotine and cotinine with apparent KM"s that were 37- and 3-fold lower than that observed for microsomes of UGT1A4-overexpressing cells against nicotine and cotinine, respectively. Nicotine 127-135 UDP glucuronosyltransferase family 1 member A4 Homo sapiens 236-242 15470160-4 2005 Trans-3"-hydroxycotinine N-glucuronidation in human liver microsomes was significantly correlated with nicotine and cotinine N-glucuronidations, which are catalyzed mainly by UDP-glucuronosyltransferase (UGT)1A4 and was inhibited by imipramine and nicotine, which are substrates of UGT1A4. Nicotine 103-111 UDP glucuronosyltransferase family 1 member A4 Homo sapiens 204-211 16141602-5 2005 Nicotine and cotinine are glucuronidated to N-glucuronides mainly by UGT1A4 and partly by UGT1A9. Nicotine 0-8 UDP glucuronosyltransferase family 1 member A4 Homo sapiens 69-75 15470160-4 2005 Trans-3"-hydroxycotinine N-glucuronidation in human liver microsomes was significantly correlated with nicotine and cotinine N-glucuronidations, which are catalyzed mainly by UDP-glucuronosyltransferase (UGT)1A4 and was inhibited by imipramine and nicotine, which are substrates of UGT1A4. Nicotine 103-111 UDP glucuronosyltransferase family 1 member A4 Homo sapiens 282-288 14570768-9 2003 The glucuronidation of nicotine and cotinine by heterologously expressed UGT1A3, UGT1A4, and UGT1A9 was also determined. Nicotine 23-31 UDP glucuronosyltransferase family 1 member A4 Homo sapiens 81-87 14570768-13 2003 UGT1A4 Supersomes also catalyzed cotinine N-glucuronidation, but at one-tenth the rate of nicotine glucuronidation. Nicotine 90-98 UDP glucuronosyltransferase family 1 member A4 Homo sapiens 0-6 14570768-15 2003 Both propofol, a UGT1A9 substrate, and imipramine, a UGT1A4 substrate, inhibited the glucuronidation of nicotine and cotinine by human liver microsomes. Nicotine 104-112 UDP glucuronosyltransferase family 1 member A4 Homo sapiens 53-59 14570768-16 2003 Taken together, these data support a role for both UGT1A9 and UGT1A4 in the catalysis of nicotine and cotinine N-glucuronidation. Nicotine 89-97 UDP glucuronosyltransferase family 1 member A4 Homo sapiens 62-68 12433823-7 2002 Nicotine and cotinine N-glucuronidations in pooled human liver microsomes were competitively inhibited by bilirubin as a substrate for UGT1A1 (K(i) = 3.9 and 3.3 micro M), imipramine as a substrate for UGT1A4 (K(i) = 6.1 and 2.7 micro M), and propofol as a substrate for UGT1A9 (K(i) = 6.0 and 12.0 micro M). Nicotine 0-8 UDP glucuronosyltransferase family 1 member A4 Homo sapiens 202-208 12433823-10 2002 In conclusion, the involvement of UGT1A1 and UGT1A9 as well as UGT1A4 in nicotine and cotinine N-glucuronidations in human liver microsomes was suggested, although the contributions of each UGT isoform could not be determined conclusively.
