Flavonols 121-130 UDP glucuronosyltransferase family 1 member A9 Homo sapiens 74-80 21068207-3 2011 This article aims to construct position (3-OH)-specific comparative molecular field analysis (CoMFA) models to describe UDP-glucuronosyltransferase (UGT) 1A9-mediated glucuronidation of flavonols, which can be used to design poor UGT1A9 substrates. Flavonols 186-195 UDP glucuronosyltransferase family 1 member A9 Homo sapiens 120-157 21068207-4 2011 The kinetics of recombinant UGT1A9-mediated 3-O-glucuronidation of 30 flavonols was characterized, and kinetic parameters (K(m), V(max), CL(int)) were obtained. Flavonols 70-79 UDP glucuronosyltransferase family 1 member A9 Homo sapiens 28-34 21068207-6 2011 To model UGT1A9-mediated glucuronidation, 30 flavonols were split into the training (23 compounds) and test (7 compounds) sets. Flavonols 45-54 UDP glucuronosyltransferase family 1 member A9 Homo sapiens 9-15 21068207-10 2011 In conclusion, the approach of coupling CoMFA analysis with a pharmacophore-based structural alignment is viable for constructing a predictive model for regiospecific glucuronidation rates of flavonols by UGT1A9.
