Abstract
UGT1A9 was found to catalyze the production of four luteolin glucuronides including three known monoglucuronides and a novel 3′ 4′diglucuronide Ko143 a potent specific inhibitor of BCRP significantly inhibited efflux of luteolin monoglucuronides from HeLa1A9 cells and increased their intracellular levels in a dosedependent manner The formation of luteolin diglucuronide was observed when intracellular concentration of total monoglucuronides went above 007 nMLan Tang Ye Li Southern Medical University and Guangzhou University of Chinese Medicine contributed equally to this paper This work was in part supported by the Programs for Fundamental Research and Development 973 program 2009CB522800 Project of National Natural Science Foundation of China 81001690 the key Project of National Natural Science Foundation of China U1203204 the Key International Joint Research Project of National Natural Science Foundation of China 81120108025 as well as the Program for Pearl River New Stars of Science and Technology in Guangzhou 2012J2200048 WJ and MH were supported by The National Institutes of Health grant NIH GM070737 The authors report no declaration of interest
