Abstract
Flavone glycosides, their aglycones, and metabolites are the major phytochemicals in dietary intake. However, there are still many unknowns about the cellular utilization and active sites of these natural products. Uridine diphosphate glucuronosyltransferases (UGTs) in the endoplasmic reticulum have gene polymorphism distribution in the population and widely mediate the absorption and metabolism of endogenous and exogenous compounds by catalyzing the covalent addition of glucuronic acid and various lipophilic chemicals. Firstly, we found that rutin, a typical flavone O-glycoside, has a stronger UGT2B7 binding effect than its metabolites. After testing a larger number of flavonoids with different aglycones, their aglycones, and metabolites, we demonstrated that typical dietary flavone O-glycosides generally have high binding affinities towards UGT2B7 protein, but the flavone C-glycosides and the phenolic acid metabolites of flavones had no significant effect on this. With the disposition of 4-methylumbelliferone examined by HPLC assay, we determined that 10 μM rutin and nicotifiorin could significantly inhibit the activity of recombinant UGT2B7 protein, which is stronger than isovitexin, vitexin, 3-hydroxyphenylacetic acid and 3,4-dihydroxyphenylacetic acid. In addition, in vitro experiments showed that in normal and doxorubicin-induced lipid composition, both flavone O-glycosides rutin and flavone C-glycosides isovitexin at 10 μM had no significant effect on the expression of UGT1A1, UGT2B4, UGT2B7, and UGT2B15 genes for 24 h exposure. The obtained results enrich the regulatory properties of dietary flavone glycosides, aglycones, and metabolites towards the catalysis of UGTs and will contribute to the establishment of a precise nutritional intervention system based on lipid bilayers and theories of nutrients on endoplasmic reticulum and mitochondria communication.

Abstract
Morinda officinalis How (MO) is one of the best-known traditional herbs and is widely cultivated in subtropical and tropical areas for many years, especially in southern China. Oligosaccharides are the major constituents in the roots of MO, which is well known for its therapeutic effects with anti-depression, anti-osteoporosis, memory-enhancing, ect. To date, the main gene families that regulate the biosynthetic pathway of MO oligosaccharides metabolism yet have been published. In our study, six cDNA libraries generated from six plants of MO were sequenced utilizing an Illumina HiSeq 4000 platform. Corresponding totals of more than 132.60 million clean reads were obtained from the six libraries and assembled into 25,812 unigenes with an average length of 1288 bp. Moreover, 6036 unigenes were found to be allocated to 26 pathways maps using several public databases, and 2538 differential expression genes (DEGs) were screened. Among them, 25 genes from three families were selected as the mainly candidate genes related to MO oligosaccharides biosynthesis. Then, the expression patterns of six DEGs closely related to MO oligosaccharides biosynthesis were verified by quantitative real-time PCR (qRT-PCR). Besides, the MO was clustered more closely to Coffea arabica of Rubiaceae. In summary, the transcriptomic analysis was used to investigate the differences in expression genes of oligosaccharides biosynthesis, with the notable outcome that several key gene families were closely linked to oligosaccharides biosynthesis.

Abstract
Herbs are often administered in combination with therapeutic drugs, raising the possibility for herb-drug interactions (HDIs). Furoquinoline alkaloids are found in Rutaceae plants, which are structurally similar and have many medicinal properties. This study aims to investigate the inhibition of four furoquinoline alkaloids on the activity of UDP-glucuronosyltransferases (UGTs).The recombinant UGTs-catalyzed glucuronidation metabolism of 4-methylumbelliferone (4-MU) was utilized to investigate the inhibition potential. Inhibition type and parameters were determined, and in silico docking was employed to elucidate the inhibition difference of furoquinoline alkaloids towards UGTs.Dictamine, haplopine, γ-fagarine and skimmianine strongly inhibited UGT1A3, UGT1A7, UGT1A9 and UGT2B4, respectively. Among them, dictamnine inhibited more than 70% of the four UGTs. Inhibition kinetics determination showed that they all exerted competitive inhibition, and the inhibition kinetic constant (Ki) was determined to be 8.3, 7.2, 3.7 and 33.9 μM, respectively. In vitro-in vivo extrapolation (IVIVE) was employed to demonstrate the inhibition possibility for four alkaloids. Skimmianine was proved to be more suitable for clinical application. In silico docking study indicated that the hydrophobic interactions played a key role in the inhibition of furoquinoline alkaloids towards three of the four UGTs. In conclusion, monitoring the interactions between furoquinoline alkaloids and drugs mainly undergoing UGTs-catalyzed metabolism is necessary.
