PF-PLC micelles ameliorate cholestatic liver injury via regulating TLR4/MyD88/NF-κB and PXR/CAR/UGT1A1 signaling pathways in EE-induced rats.
    International journal of pharmaceutics, 2022, Mar-05, Volume: 615

    Paeoniflorin (PF) has a certain therapeutic effect on cholestasis liver injury. To further improve the bioavailability of PF and play its pharmacological role in liver protection, PF-phospholipid complex micelles (PF-PLC micelles) were prepared based on our previous research on PF-PLC. The protective effects of PF and PF-PLC micelles on cholestasis liver injury induced by 17α-ethynylestradiol (EE) were compared, and the possible mechanisms were further explored. Herein, we showed that PF-PLC micelles effectively improved liver function, alleviated liver pathological damage, and localized infiltration of inflammatory cells. Mechanism studies indicated that PF-PLC micelles treatment could suppress the TLR4/MyD88/NF-κB pathway, and further reduce the levels of pro-inflammatory factors. Meanwhile, our experimental results demonstrated that the beneficial effect of PF-PLC micelles on EE-induced cholestasis may be achieved by the upregulation of nuclear receptors and metabolic enzymes (PXR/CAR/UGT1A1). All these results indicate that PF-PLC micelles have great potential in the treatment of cholestatic liver disease.

Paeoniflorin attenuates ANIT-induced cholestasis by inhibiting apoptosis in vivo via mitochondria-dependent pathway.
    Biomedicine & pharmacotherapy = Biomedecine & pharmacotherapie, 2017, Volume: 89

    Apoptosis induced by the bile acids in the liver is considered to play a pivotal role in the pathogenesis of cholestatic disease. Increasing evidence has demonstrated that Paeoniflorin (PF) exerts therapeutic effect on severe cholestatic liver diseases. However, whether PF could protect against alpha-naphthylisothiocyanate (ANIT)-induced cholestasis by inhibiting apoptosis remains unclear. In this study, we mainly investigated the effect and anti-apoptosis mechanism of PF on cholestasis. Experimental results indicated that PF pretreatment could attenuate liver damage and cholestasis by ANIT in rats, lift the biliary excretion in addition to decrease serum indices (ALT, AST, DBIL, TBIL, TBA, ALP and ϒ-GT) and conspicuous neutrophil infiltration and cell apoptosis in liver evidenced by TUNEL staining. Furthermore, the pro-apoptosis genes expression of Bax, Caspase-9 and Caspase-3 increased by ANIT were prominently reduced after PF treatment. The increase of anti-apoptosis gene and main regulator Bcl-2 in mitochondria by ANIT was largely reversed by PF pre-treatment. In summary, our study demonstrated that PF pre-treatment not only significantly attenuated ANIT-induced cholestasis and liver injury, but also largely reduced cell apoptosis in liver, thus may act as a potential therapeutic agent for cholestasis disease.

Serum Metabolomic Profiling in a Rat Model Reveals Protective Function of Paeoniflorin Against ANIT Induced Cholestasis.
    Phytotherapy research : PTR, 2016, Volume: 30, Issue:4

    Cholestasis is a leading cause of hepatic accumulation of bile acids resulting in liver injury, fibrosis, and liver failure. Paeoniflorin displays bright prospects in liver protective effect. However, its molecular mechanism has not been well-explored. This study was designed to assess the effects and possible mechanisms of paeoniflorin against alpha-naphthylisothiocyanate-induced liver injury. Ultraperformance liquid chromatography coupled with quadrupole time-of-flight combined with principle component analysis and partial least squares discriminant analysis were integrated to obtain differentiating metabolites for the pathways and clarify mechanisms of disease. The results indicated that paeoniflorin could remarkably downregulate serum biochemical indexes and alleviate the histological damage of liver tissue. Different expression of 14 metabolites demonstrated that paeoniflorin mainly regulated the dysfunctions of glycerophospholipid metabolism and primary bile acid biosynthesis. Moreover, several pathways such as arginine and proline metabolism, ether lipid metabolism, and arachidonic acid metabolism were also related to the efficacy. In conclusion, paeoniflorin has indicated favorable pharmacological effect on serum biochemical indexes and pathological observation on cholestatic model. And metabolomics is a promising approach to unraveling hepatoprotective effects by partially regulating the perturbed pathways, which provide insights into mechanisms of cholestasis.

Paeoniflorin ameliorates ANIT-induced cholestasis by activating Nrf2 through an PI3K/Akt-dependent pathway in rats.
    Phytotherapy research : PTR, 2015, Volume: 29, Issue:11

    Cholestasis causes hepatic accumulation of bile acids leading to liver injury, fibrosis and liver failure. Paeoniflorin, the major active compound isolated from the roots of Paeonia lactiflora pall and Paeonia veitchii Lynch, is extensively used for liver diseases treatment in China. However, the mechanism of paeoniflorin's hepatoprotective effect on cholestasis has not been investigated yet. In this study, we administered paeoniflorin to rats for 3 days prior to alpha-naphthylisothiocyanate (ANIT) administration for once, then went on administering paeoniflorin to rats for 3 days. The data demonstrated that paeoniflorin significantly prevented ANIT-induced change in serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphates (ALP), serum total bilirubin (TBIL), direct bilirubin (DBIL), total bile acid (TBA) and gamma-glutamyl transpeptidase (γ-GT). Histology examination revealed that paeoniflorin treatment rats relieved more liver injury and bile duct proliferation than ANIT-administered rats. Moreover, our data indicated that paeoniflorin could restore glutathione (GSH) and its related synthase glutamate-cysteine ligase catalytic subunit (GCLc) and glutamate-cysteine ligase modifier subunit (GCLm) in ANIT-treated group. In addition, the RNA and protein expression of Akt and nuclear factor-E2-related factor-2 (Nrf2) were also activated by paeoniflorin in ANIT-induced rats. These findings indicated that paeoniflorin protected ANIT-induced cholestasis and increased GSH synthesis by activating Nrf2 through PI3K/Akt-dependent pathway. Therefore, paeoniflorin might be a potential therapeutic agent for cholestasis.

Paeoniflorin protects against ANIT-induced cholestasis by ameliorating oxidative stress in rats.
    Food and chemical toxicology : an international journal published for the British Industrial Biological Research Association, 2013, Volume: 58

    Paeoniflorin, one of the primary bioactive components in Chi shao, are widely used in traditional Chinese medicine. A lot of evidences suggest that Paeoniflorin has potential anti-oxidant effects. However, whether Paeoniflorin plays roles in cholestasis is unclear. In this study, we examined the protective effect of Paeoniforin against alpha-naphthylisothicaynate (ANIT)-induced cholestasis in rats. Our data demonstrated that the high (0.2 g/kg body weight) and medium (0.1 g/kg body weight) doses of Paeoniflorin significantly prevented ANIT-induced changes in bile flow and the serum levels of total bilirubin, direct bilirubin, total bile acid, γ-glutamyltranspeptidase, glutamate-pyruvate transaminase, glutamate-oxaloacetic transaminase and alkaline phosphatase. Moreover, we also found that Paeoniflorin significantly inhibited nitric oxide and malondialdehyde production, and restored glutathione decrease induced by ANIT. EPR data further indicated that Paeoniflorin inhibited ANIT-mediated reactive oxygen species (ROS) production. The overexpression of NADPH oxidase 4 induced by ANIT were significantly reversed when treated with Paeoniflorin, suggesting that Paeoniflorin could scavenge ROS via inhibiting NADPH oxidase 4 expression. Paeoniflorin treatment could also relieve ANIT-induced liver pathological injuries as indicated by histological assay. These findings indicate that Paeoniflorin exerts a dose-dependent protective effect on ANIT-induced cholestatic liver injury in rats, and the mechanism of this activity is related to its attenuation of oxidative stress in liver tissue.

Comparative pharmacokinetic study of paeoniflorin and albiflorin after oral administration of Radix Paeoniae Rubra in normal rats and the acute cholestasis hepatitis rats.
    Fitoterapia, 2012, Volume: 83, Issue:2

    A comparative study was designed and conducted to compare the pharmacokinetic difference of paeoniflorin and albiflorin after oral administration of Radix Paeoniae Rubra to normal rats and the acute cholestasis hepatitis rats induced by alpha-naphthylisothiocyanate (ANIT). UPLC-ESI-MS/MS method was employed to determine the level of paeoniflorin and albiflorin in rat plasma using geniposide as the internal standard (IS). Unpaired Student's t-test was used for the statistical comparison. The investigation showed that there were significant differences between the normal rats and the acute cholestasis hepatitis rat groups in calculated parameters, such as AUC(0-t), AUC(0-∞), T(max) and CLz/F. The results indicated that acute liver injury in rats could alter the pharmacokinetics of drug. Since patients are the final users of the drug, it is essential to investigate the pharmacokinetics of the drug in disease status. Therefore, we used normal rats and the acute cholestasis hepatitis rats to study pharmacokinetics of Radix Paeoniae Rubra with the purpose of examining the influence of disease on the metabolic course.
