Morinda officinalis iridoid glycosides alleviate methotrexate-induced liver injury in CIA rats by increasing liver autophagy and improving lipid metabolism homeostasis. JOURNAL OF ETHNOPHARMACOLOGY 2024; 333:118486. [PMID: 38914148 DOI: 10.1016/j.jep.2024.118486] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/22/2024] [Revised: 06/18/2024] [Accepted: 06/20/2024] [Indexed: 06/26/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Morinda officinalis How. is a commonly used traditional Chinese herb with the pharmacological properties of tonifying liver and kidney, and enhancing bone and muscle. Iridoid glycosides are the predominant components of this plant, including monotropein, asperuloside, deacetylasperuloside and deacetylasperulosidic acid with their contents reaching more than 2%. Methotrexate (MTX) is the drug of choice for the treatment of rheumatoid arthritis (RA), but liver injury induced by MTX limits its wider use for RA. Morindaofficinalis iridoid glycoside (MOIG) is reported as having anti-RA and hepatoprotective effects, but the exact efficacy on MTX-induced liver injury and the underlying molecular mechanism remain unclear. AIM To elucidate the mitigating effect of MOIG against liver injury in RA rats treated with MTX, and explore the possible mechanism. MATERIALS AND METHODS The effect and mechanism of MOIG were investigated in Wistar rats with collagen-induced arthritis (CIA) which were then treated with MTX, and MTX-induced hepatocyte injury in vitro. Network pharmacological and transcriptomic analyses were conducted to predict the possible mechanisms of MOIG in mitigating MTX-induced liver injury, and lipidomic analysis was performed to further verify the regulatory effects of MOIG on lipid metabolism. BRL-3A hepatocytes were used to evaluate the regulatory effects of MOIG against MTX-associated liver injury. RESULTS MOIG treatment enhanced the anti-RA effect of MTX, and mitigated oxidative damage, inflammation and apoptosis of liver tissues in CIA rats treated with MTX. Network pharmacological and transcriptomic analyses demonstrated that MOIG attenuated liver injury by regulating autophagy and lipid metabolism. The result of lipidomic analysis showed that MOIG reversed the disturbance of lipid metabolism of the liver tissue in CIA rats after MTX treatment. In addition, MOIG also inhibited the apoptosis, reduced the levels of lactate dehydrogenase (LDH), aspartate aminotransferase (ALT) and alanine aminotransferase (AST), regulated oxidative stress, and increased the formation of autophagosome and translocation of LC3 in the nucleus and expression of autophagy regulatory genes Beclin-1, ATG5, LC3Ⅱ, ATG7 and ATG12 in hepatocytes subjected to MTX damage. CONCLUSION Our findings demonstrated that MOIG could ameliorate MTX-induced liver injury in the treatment of RA through increasing hepatocyte autophagy and improving lipid metabolism homeostasis.

Abstract
Metformin is a classical drug used to treat type 2 diabetes. With the development of research on metformin, it has been found that metformin also has several advantages aside from its hypoglycemic effect, such as anti-inflammatory, anti-aging, anti-cancer, improving intestinal flora, and other effects. The prevention of inflammation is critical because chronic inflammation is associated with numerous diseases of considerable public health. Therefore, there has been growing interest in the role of metformin in treating various inflammatory conditions. However, the precise anti-inflammatory mechanisms of metformin were inconsistent in the reported studies. Thus, this review aims to summarize various currently known possible mechanisms of metformin involved in inflammatory diseases and provide references for the clinical application of metformin.

Abstract
The aim of this study is to investigate the efficacy and the underlying mechanism of Veronica incana in osteoarthritis (OA) induced by intraarticular injection of monosodium iodoacetate (MIA). The selected major four compounds (A-D) of V. incana were found from fractions 3 and 4. Its structure elucidation was determined by liquid chromatography-electrospray ionization-mass spectrometry (LC-ESI-MS) data analysis and nuclear magnetic resonance (NMR) data comparison with literature. MIA (50 μL with 80 mg/mL) for the animal experiment was injected into the right knee joint. The V. incana was administered orally every day to rats for 14 days from 7 days after MIA treatment. Finally, we confirmed the four compounds: (A) verproside; (B) catalposide; (C) 6-vanilloylcatapol; and (D) 6-isovanilloylcatapol. When we evaluated the effect of V. incana on the MIA injection-induced knee OA model, there were a noticeable initial decreased in hind paw weight-bearing distribution compared to the Normal group (P < .001), but V. incana supplementation resulted in a significant increase in the weight-bearing distribution to the treated knee (P < .001). Moreover, the V. incana treatment led to a decrease in the levels of liver function enzymes and tissue malondialdehyde (P < .05 and .01). The V. incana significantly suppressed the inflammatory factors through the nuclear factor-kappa B signaling pathway and downregulated the expression of matrix metalloproteinases, which are involved in the degradation of the extracellular matrix (P < .01 and .001). In addition, we confirmed the alleviation of cartilage degeneration through tissue stains. In conclusion, this study confirmed the major four compounds of V. incana and suggested that V. incana could serve as an anti-inflammatory candidate agent for patients with OA.

The Potential Protective Effect of Iridoid Glycosides Isolated From Osmanthus fragrans Seeds Against the Development of Immune Liver Injury in Mice. Front Pharmacol 2021; 12:760338. [PMID: 34819861 PMCID: PMC8606819 DOI: 10.3389/fphar.2021.760338] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2021] [Accepted: 10/12/2021] [Indexed: 12/04/2022] Open
Abstract
Objective: The iridoid glycosides were extracted and separated from Osmanthus fragrans seeds, and the potential protective effect of Osmanthus fragrans seed extract on concanavalin A-induced immune liver injury in mice was studied. Methods:Osmanthus fragrans seeds were extracted by 95% ethanol reflux. Then, the iridoid glycosides were enriched by extraction refined through petroleum ether (60°C–90°C), ethyl acetate, and water-saturated n-butanol in sequence, so as to purify the n-butanol part (Osmanthus fragrans seed’s n-butanol extraction, OFSN) by macroporous resin. Specnuezhenide and Nuezhenoside G13 were used as the reference substances to determine the concentration of iridoid glycosides by HPLC. On this basis, a mouse immune liver injury model was established by tail intravenous concanavalin A (20 mg/kg); the contents of serum ALT, AST, IFN-γ, and TNF-α and the contents of liver tissue MDA and SOD were determined; the pathological changes of the liver by HE staining were observed; and the expression levels of p38MAPK and p-p38mapk in liver tissue were detected by WB. Results: The linearity, precision, repeatability, recovery, and stability of HPLC all met the requirements by validating with the methodology. The contents of Specnuezhenide and Nuezhenoside G13 in the n-butanol extracts were 39.20% and 39.88%, respectively. Actually, their contents can reach up to 82.56% and 87.9% after being purified by macroporous resin. The results of animal experiments show that OFSN could significantly reduce the liver and spleen index, reduce the ALT and AST contents in plasma and the MDA content in liver tissue, and then increase the SOD content. Besides, OFSN could also reduce the plasma IFN-γ and TNF-α levels. The HE staining result indicates that the pathological changes in the liver tissues of mice treated with OFSN are alleviated to different degrees while the WB result suggests that OFSN could significantly inhibit the expression of p-p38mapk. Conclusion:Osmanthus fragrans seeds are rich in iridoid glycosides, which has a good protective effect on mouse immune liver injury caused by concanavalin A. The mechanism may be related to inhibiting the phosphorylation of p38MAPK, inhibiting the release of inflammatory mediators, improving the antioxidant capacity of liver cells, and weakening the occurrence of lipid peroxidation.

Hua W, Zhang S, Lu Q, Sun Y, Tan S, Chen F, Tang L. Protective effects of n-Butanol extract and iridoid glycosides of Veronica ciliata Fisch. Against ANIT-induced cholestatic liver injury in mice. JOURNAL OF ETHNOPHARMACOLOGY 2021; 266:113432. [PMID: 33011367 DOI: 10.1016/j.jep.2020.113432] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/30/2019] [Revised: 06/15/2020] [Accepted: 09/27/2020] [Indexed: 06/11/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Veronica ciliata Fisch. is a traditional medical herb that present in more than 100 types of Tibetan medicine prescriptions, most of which are used for liver disease therapy. Iridoid glycosides have been identified as the major active components of V.ciliata with a variety of biological activities. AIMS OF THE STUDY The aim of this study is to explore the protective effect and potential mechanism of n-Butanol extract (BE) and iridoid glycosides (IG) from V.ciliata against ɑ-naphthyl isothiocyanate (ANIT)-induced hepatotoxicity and cholestasis in mice. MATERIALS AND METHODS Mice were intragastrically (i.g.) given BE and IG at different dose or positive control ursodeoxycholic acid (UCDA) once a day for 14 consecutive days, and were treated with ANIT to cause liver injury on day 12th. Serum levels of hepatic injury markers and cholestasis indicators, liver index and liver histopathology were measured to evaluate the effect of BE and IG on liver injury caused by ANIT. The protein levels of tumor necrosis factor-α (TNF-α), nuclear factor kappa B(NF-κB), interleukin-6 (IL-6), Na+/taurocholate cotransporting polypeptide (NTCP), bile salt export pump (BSEP), multidrug resistance-associated protein 2 (MRP2), and the levels of oxidative stress indicators in liver tissue were investigated to reveal the underlying protective mechanisms of BE and IG against ANIT-induced hepatotoxicity and cholestasis. RESULTS The n-Butanol extract (BE) and iridoid glycosides (IG) isolated from V.ciliata significantly decreased serum level of cholestatic liver injury markers aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), γ-glutamyl transferase (GGT), total bile acid (TBA), total bilirubin (TBIL), and direct bilirubin (DBIL) in ANIT-treated mice. Histopathology of the liver tissue showed that pathological damages were relieved upon BE and IG treatment. Meanwhile, the results indicated BE and IG notably restored relative liver weights, inhibited oxidative stress induced by ANIT through increasing hepatic level of superoxide dismutase (SOD), reduced glutathione (GSH), catalase (CAT) and decreasing hepatic content of malondialdehyde (MDA). Western blot revealed that BE and IG inhibited the expression of pro-inflammatory factors TGF-α, IL-6 and NF-κB. Furthermore, the decreased protein expression of bile acid transporters NTCP, BSEP, MRP2 were upregulated by BE and IG in a dose-dependent manner. CONCLUSION The results have demonstrated that BE and IG exhibited a dose-dependently protective effect against ANIT-induced liver injury with acute intrahepatic cholestasis in mice, which might be related to the regulation of oxidative stress, inflammatory response and bile acid transport. In addition, these findings pointed out that iridoid glycosides as main active components of V.ciliata play a critical role in hepatoprotective effect of V.ciliata.

Abstract
Antioxidants play an essential role in human health, as they have been found to be capable of lowering the incidence of many diseases, such as cancer and angiocardiopathy. Currently, more attention is paid to natural antioxidants because of the possible insecurity of synthetic antioxidants. Thus, the development of efficient techniques or methods to separate antioxidants from natural sources is requested urgently. High-speed counter current chromatography (HSCCC) is a unique support-free liquid-liquid chromatographic technique and has been widely applied in the field of separation of natural products. In this review, we summarize and analyze the related researches on the application of HSCCC in the separation of various natural antioxidants so far. The purpose of the article is to provide a certain theoretical support for the separation of natural antioxidants by HSCCC, and to make full use of advantages of HSCCC in the separation of bioactive components. In particular, some key problems associated with the separation strategies, the structural categories of natural antioxidants, solvent system choices, and the application of different elution modes in HSCCC separation, are summarized and commented. We expect that the content reviewed can offer more evidence for the development of the field of natural antioxidants separation, so as to achieve large-scale preparation of natural antioxidants.

Abstract
The old adage says, "you are what you eat." And although it is a banality repeated by many with a grain of salt, it also has quite a bit of truth in it, as the products we eat have a considerable impact on our health. Unfortunately, humanity is eating worse from one year to another, both in terms of product quality and eating habits. At the same time, it is brought up frequently that plant products should form the basis of our diet. This issue was also reflected in the new version of the food pyramid. Iridoids and anthocyanins are groups of plant compounds with proven beneficial effects on health. Both groups affect the cardiovascular system and the liver functions. Although many mechanisms of action and the therapeutic effects of these compounds have already been learned, intensive animal and clinical research is still underway to explore their new curative mechanisms and effects or to broaden our knowledge of those previously described. In this article, we review the effects of natural iridoids and anthocyanins on selected parameters of liver and cardiovascular system functions.

Abstract
Veronica is the largest genus in the flowering plant family Plantaginaceae and comprises approximately 500 species. The genus was formerly placed in the Scrophulariaceae family, some species of which have been used in traditional medicine for the treatment of influenza, respiratory diseases, hemoptysis, laryngopharyngitis, cough, hernia, cancer, edema, and wounds. This review comprehensively summarizes the current information on the traditional uses, phytochemistry, and pharmacology of the genus Veronica on the basis of articles published from 1970 to 2018. More than 260 compounds have been isolated, and chemotaxonomic investigations of Veronica have revealed that iridoid glucosides - including aucubin, catalpol, and 6-O-catalpol derivatives - are characteristic of this genus. Modern pharmacological studies and clinical practice have demonstrated that extracts or monomeric compounds from Veronica have several pharmacological actions, such as anti-inflammatory, anti-oxidative, anticancer, antibacterial, anti-angiogenic, antineurodegenerative, neuroprotective, and hepatoprotective effects both in vivo and in vitro.

Abstract
Iridoids are a class of active compounds that widely exist in the plant kingdom. In recent years, with advances in phytochemical research, many compounds with novel structure and outstanding activity have been identified. Iridoid compounds have been confirmed to mainly exist as the prototype and aglycone and Ι and II metabolites, by biological transformation. These metabolites have been shown to have neuroprotective, hepatoprotective, anti-inflammatory, antitumor, hypoglycemic, and hypolipidemic activities. This review summarizes the new structures and activities of iridoids identified locally and globally, and explains their pharmacokinetics from the aspects of absorption, distribution, metabolism, and excretion according to the differences in their structures, thus providing a theoretical basis for further rational development and utilization of iridoids and their metabolites.

Pharmaceutics 2019; 11:pharmaceutics11070355. [PMID: 31336576 PMCID: PMC6681058 DOI: 10.3390/pharmaceutics11070355] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2019] [Revised: 07/18/2019] [Accepted: 07/19/2019] [Indexed: 01/06/2023] Open
Abstract
Catalposide, an active component of Veronica species such as Catalpa ovata and Pseudolysimachion lingifolium, exhibits anti-inflammatory, antinociceptic, anti-oxidant, hepatoprotective, and cytostatic activities. We characterized the in vitro metabolic pathways of catalposide to predict its pharmacokinetics. Catalposide was metabolized to catalposide sulfate (M1), 4-hydroxybenzoic acid (M2), 4-hydroxybenzoic acid glucuronide (M3), and catalposide glucuronide (M4) by human hepatocytes, liver S9 fractions, and intestinal microsomes. M1 formation from catalposide was catalyzed by sulfotransferases (SULTs) 1C4, SULT1A1*1, SULT1A1*2, and SULT1E1. Catalposide glucuronidation to M4 was catalyzed by gastrointestine-specific UDP-glucuronosyltransferases (UGTs) 1A8 and UGT1A10; M4 was not detected after incubation of catalposide with human liver preparations. Hydrolysis of catalposide to M2 was catalyzed by carboxylesterases (CESs) 1 and 2, and M2 was further metabolized to M3 by UGT1A6 and UGT1A9 enzymes. Catalposide was also metabolized in extrahepatic tissues; genetic polymorphisms of the carboxylesterase (CES), UDP-glucuronosyltransferase (UGT), and sulfotransferase (SULT) enzymes responsible for catalposide metabolism may cause inter-individual variability in terms of catalposide pharmacokinetics.

The Preventive Effects and the Mechanisms of Action of Navel Orange Peel Hydroethanolic Extract, Naringin, and Naringenin in N-Acetyl-p-aminophenol-Induced Liver Injury in Wistar Rats. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2019; 2019:2745352. [PMID: 31049130 PMCID: PMC6458942 DOI: 10.1155/2019/2745352] [Citation(s) in RCA: 52] [Impact Index Per Article: 10.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/28/2018] [Accepted: 12/24/2018] [Indexed: 01/14/2023]
Abstract
N-Acetyl-p-aminophenol (APAP) or acetaminophen is the most common drug ingredient worldwide. It is found in more than 600 different over-the-counter and prescription medicines. Its long-term and overdose use is highly toxic and may result in liver injury. Thus, this study was designed to assess the preventive effects and to suggest the mechanisms of action of the navel orange peel hydroethanolic extract, naringin, and naringenin in APAP-induced hepatotoxicity in male Wistar rats. APAP was administered to male Wistar rats at a dose level of 0.5 g/kg body weight (b.w.) by oral gavage every other day for 4 weeks. APAP-administered rats were treated with the navel orange peel hydroethanolic extract (50 mg/kg b.w.), naringin (20 mg/kg b.w.), and naringenin (20 mg/kg b.w.) by oral gavage every other day during the same period of APAP administration. The treatments of APAP-administered rats with the peel extract, naringin, and naringenin produced a significant decrease in the elevated serum AST, ALT, ALP, LDH, and GGT activities as well as total bilirubin and TNF-α levels while they induced a significant increase in the lowered serum albumin and IL-4 levels. The treatments also resulted in a significant decrease in the elevated liver lipid peroxidation and enhanced the liver GSH content and SOD, GST, and GPx activities as compared with APAP-administered control; the peel extract was the most potent in improving the liver LPO, GSH content, and GPx activity. In addition, the three treatments significantly downregulated the elevated hepatic proapoptotic mediators p53, Bax, and caspase-3 and significantly upregulated the suppressed antiapoptotic protein, Bcl-2, in APAP-administered rats. In association, the treatments markedly amended the APAP-induced liver histopathological deteriorations that include hepatocyte steatosis, cytoplasmic vacuolization, hydropic degeneration, and necrosis together with mononuclear leucocytic and fibroblastic inflammatory cells' infiltration. In conclusion, the navel orange peel hydroethanolic extract, naringin, and naringenin may exert their hepatopreventive effects in APAP-administered rats via enhancement of the antioxidant defense system and suppression of inflammation and apoptosis.

Abstract
Acetaminophen (APAP) overdose is the leading cause of drug-induced acute liver failure in many developed countries. Mitochondrial oxidative stress is considered to be the predominant cellular event in APAP-induced liver injury. Accordingly, N-acetyl cysteine, a known scavenger of reactive oxygen species (ROS), is recommended as an effective clinical antidote against APAP-induced acute liver injury (AILI) when it is given at an early phase; however, the narrow therapeutic window limits its use. Hence, the development of novel therapeutic approaches that can offer broadly protective effects against AILI is clearly needed. To this end, it is necessary to better understand the mechanisms of APAP hepatotoxicity. Up to now, in addition to mitochondrial oxidative stress, many other cellular processes, including phase I/phase II metabolism, endoplasmic reticulum stress, autophagy, sterile inflammation, microcirculatory dysfunction, and liver regeneration, have been identified to be involved in the pathogenesis of AILI, providing new targets for developing more effective therapeutic interventions against APAP-induced liver injury. In this review, we summarize intracellular and extracellular events involved in APAP hepatotoxicity, along with emphatic discussions on the possible therapeutic approaches targeting these different cellular events.

Active Fragment of Veronica ciliata Fisch. Attenuates t-BHP-Induced Oxidative Stress Injury in HepG2 Cells through Antioxidant and Antiapoptosis Activities. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2017; 2017:4727151. [PMID: 29362666 PMCID: PMC5736906 DOI: 10.1155/2017/4727151] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/22/2017] [Accepted: 10/04/2017] [Indexed: 01/05/2023]
Abstract
Excessive amounts of reactive oxygen species (ROS) in the body are a key factor in the development of hepatopathies such as hepatitis. The aim of this study was to assess the antioxidation effect in vitro and hepatoprotective activity of the active fragment of Veronica ciliata Fisch. (VCAF). Antioxidant assays (DPPH, superoxide, and hydroxyl radicals scavenging) were conducted, and hepatoprotective effects through the application of tert-butyl hydroperoxide- (t-BHP-) induced oxidative stress injury in HepG2 cells were evaluated. VCAF had high phenolic and flavonoid contents and strong antioxidant activity. From the perspective of hepatoprotection, VCAF exhibited a significant protective effect on t-BHP-induced HepG2 cell injury, as indicated by reductions in cytotoxicity and the levels of ROS, 8-hydroxydeoxyguanosine (8-OHdG), and protein carbonyls. Further study demonstrated that VCAF attenuated the apoptosis of t-BHP-treated HepG2 cells by suppressing the activation of caspase-3 and caspase-8. Moreover, it significantly decreased the levels of ALT and AST, increased the activities of acetyl cholinesterase (AChE), glutathione (GSH), superoxide dismutase (SOD), and catalase (CAT), and increased total antioxidative capability (T-AOC). Collectively, we concluded that VCAF may be a considerable candidate for protecting against liver injury owing to its excellent antioxidant and antiapoptosis properties.

Multiple UDP-Glucuronosyltransferase and Sulfotransferase Enzymes are Responsible for the Metabolism of Verproside in Human Liver Preparations. Molecules 2017; 22:molecules22040670. [PMID: 28441724 PMCID: PMC6154560 DOI: 10.3390/molecules22040670] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2017] [Revised: 04/17/2017] [Accepted: 04/19/2017] [Indexed: 02/05/2023] Open
Abstract
Verproside, an active iridoid glycoside component of Veronica species, such as Pseudolysimachion rotundum var. subintegrum and Veronica anagallis-aquatica, possesses anti-asthma, anti-inflammatory, anti-nociceptive, antioxidant, and cytostatic activities. Verproside is metabolized into nine metabolites in human hepatocytes: verproside glucuronides (M1, M2) via glucuronidation, verproside sulfate (M3) via sulfation, picroside II (M4) and isovanilloylcatalpol (M5) via O-methylation, M4 glucuronide (M6) and M4 sulfate (M8) via further glucuronidation and sulfation of M4, and M5 glucuronide (M7) and M5 sulfate (M9) via further glucuronidation and sulfation of M5. Drug-metabolizing enzymes responsible for verproside metabolism, including sulfotransferase (SULT) and UDP-glucuronosyltransferase (UGT), were characterized. The formation of verproside glucuronides (M1, M2), isovanilloylcatalpol glucuronide (M7), and picroside II glucuronide (M6) was catalyzed by commonly expressed UGT1A1 and UGT1A9 and gastrointestinal-specific UGT1A7, UGT1A8, and UGT1A10, consistent with the higher intrinsic clearance values for the formation of M1, M2, M6, and M7 in human intestinal microsomes compared with those in liver microsomes. The formation of verproside sulfate (M3) and M5 sulfate (M9) from verproside and isovanilloylcatalpol (M5), respectively, was catalyzed by SULT1A1. Metabolism of picroside II (M4) into M4 sulfate (M8) was catalyzed by SULT1A1, SULT1E1, SULT1A2, SULT1A3, and SULT1C4. Based on these results, the pharmacokinetics of verproside may be affected by the co-administration of relevant UGT and SULT inhibitors or inducers.
