JOURNAL OF ETHNOPHARMACOLOGY 2024; 318:116959. [PMID: 37487965 DOI: 10.1016/j.jep.2023.116959] [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: 03/15/2023] [Revised: 05/22/2023] [Accepted: 07/21/2023] [Indexed: 07/26/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The Suxiao Jiuxin Pill (SJP) has been used for treating chronic stable angina (SA) for more than 40 years in China. SJP is composed of two Chinese herbs and has the effect of activating blood and promoting qi, according to traditional Chinese medicine (TCM) theory. AIM OF THE STUDY The study aims to determine the effects of adjunct SJP on conventional therapy in patients with SA which provides a complementary choice and its evidence for clinical medication for treating SA. MATERIALS AND METHODS Participants with SA were recruited and randomized 1:1 to either the SJP group or the control group for 24 weeks. Both groups received conventional treatment according to local tertiary hospital protocols, and the participants received additional SJP (composed of Ligusticum wallichii and Borneol) or placebo in treatment and control groups respectively. The primary outcome was the curative efficacy rate at week 4. Secondary outcomes are the curative efficacy rate, the total score of angina pectoris symptoms, CCS Angina Classification improvement, Seattle Angina Questionnaire (SAQ) score, TCM syndrome scores (TCMSS), and the curative efficacy rate of TCMSS. Adverse events and adverse drug reactions were observed and recorded for safety analysis. RESULTS A total of 324 participants with SA from 13 hospitals in China were enrolled in this trial. Compared with the control group, the curative efficacy rate of SA, the curative efficacy rate of TCMSS significantly increased, and the total score of angina pectoris symptoms and TCMSS significantly reduced in the SJP group at week 4, 12, and 24, accompanied by the statistically significant improvement in the curative efficacy rate based on CCS grade reduction (all P < 0.05). Furthermore, the SAQ score (physical limitation, angina stability, and treatment satisfaction) was evaluated as the quality of life significantly improved after treatment (P < 0.05). The medication compliance, concomitant medication, and rates of adverse events were similar between the two groups (P > 0.05). CONCLUSION The present prospective, multicenter, randomized, double-blind, placebo-controlled, clinical trial confirms that adjunct SJP to conventional treatment increased the curative efficacy and life quality of SA patients with no significant adverse drug reactions during the clinical application.

Zhang Y, Niu H, Liu J, Xie W, Jin Y, Zhang Z. Evaluation of the impact of vindoline, an active components of Catharanthus roseus, on rat hepatic cytochrome P450 enzymes by using a cocktail of probe drugs. PLoS One 2023; 18:e0289656. [PMID: 37535556 PMCID: PMC10399899 DOI: 10.1371/journal.pone.0289656] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2023] [Accepted: 07/23/2023] [Indexed: 08/05/2023] Open
Abstract
The objection of this study was to investigate the effects of vindoline(VDL) on the cytochrome P450 (CYP 450) isoforms (CYP1A2, 2B, 2C11, 2D1 and 3A) in rats. Firstly, the rats were randomly divided into VDL pretreatment group and blank group, each group had six rats. VDL pretreatment group was administrated VDL (20 mg·kg-1) by oral gavage for fifteen days consecutively, and the equivalent CMC-Na solution without VDL was given to the blank group by gavage. Secondly, a cocktail of caffeine, bupropion, diclofenac, dextromethorphan and midazolam was then administered on the sixteenth day. Finally, blood samples were collected at the specified time point, and the plasma concentration of the probe drug was determined by UHPLC-QTOF-MS/MS. The effects of VDL on the activity of these CYP enzymes in rats were evaluated by pharmacokinetic parameters. VDL pretreatment group compared with the blank group, accelerated the metabolism of diclofenac, and weakened the metabolism of caffeine. These results suggested that VDL could induce the activity of CYP2C11, and inhibits the activity of CYP1A2, but had no significant effects on CYP2B, CYP2D1 and CYP3A. The results in this study can provide beneficial information for the later clinical application of VDL.

Liu X, Wang Q, Chen M, Tao J, Wang J, Liu S, Hou J, Li D, Wang R. Interaction between Changan Granule and its main components in the plasma and CYP450 enzymes. JOURNAL OF ETHNOPHARMACOLOGY 2023; 308:116303. [PMID: 36841379 DOI: 10.1016/j.jep.2023.116303] [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: 12/05/2022] [Revised: 02/16/2023] [Accepted: 02/17/2023] [Indexed: 06/18/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Changan Granule (CAG) is a Chinese patent drug developed based on an empirical prescription in accordance with the formulation theory of Traditional Chinese Medicine. The prescription is composed of eight herbal drugs which have been traditionally used by Chinese people for a long history. It has effects of invigorating spleen and supplementing qi, as well as regulating liver and ceasing diarrhea, and is indicated for the treatment of irritable bowel syndrome (IBS). AIM OF THE STUDY This study was aimed to investigate the interaction between CAG and its main components and cytochrome P450 (CYP450) enzymes so as to characterize the major metabolites and metabolic enzymes and evaluate the safety concerns to its clinical use. MATERIALS AND METHODS Both in vivo and in vitro experiments using such as diarrhea-predominant IBS (IBS-D) rat model, HepG2 cells, and human liver microsomes (HLM) were carried out to investigate the interaction between CAG and its main components and CYP450 enzymes. Real-time quantitative PCR (qPCR), ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS), and cocktail probes were employed to qualitatively or quantitatively measure the metabolites and metabolic enzymes. RESULTS CAG inhibited the enzyme activities of CYP1A2, CYP2E1, CYP2D6, CYP2C9, and CYP3A4 and the mRNA expressions of CYP2E1, CYP2C9, CYP3A4, and CYP2D6 in vitro. CAG down-regulated the increased expression of CYP1A2 and up-regulated the decreased expression of CYP3A1 in vivo. Twenty-two metabolites were characterized from the main components of CAG after incubation with HLM in vitro. CYP2D6, CYP2E1, CYP3A4 and CYP2C9 were identified as the characteristic metabolic enzymes. CONCLUSIONS This study provides a reference for clinical application of CAG in safety. CAG and CYP450 enzymes are interacted. CAG is mainly metabolized by CYP2E1 and CYP2D6. The expression of CYP2E1 and CYP2D6 are more susceptible to be influenced by CAG in comparison with that of CYP3A4, CYP2C9 and CYP1A2. It implies the potential risk of interaction when CAG is taken together with the drugs metabolized by CYP2E1 and CYP2D6.

JOURNAL OF ETHNOPHARMACOLOGY 2023; 312:116529. [PMID: 37086873 DOI: 10.1016/j.jep.2023.116529] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/01/2022] [Revised: 04/17/2023] [Accepted: 04/18/2023] [Indexed: 05/03/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The Suxiao Jiuxin pill (SJP) is a Chinese medical patent drug on the national essential drug list of China, with well-established cardiovascular protective effects in the clinic. However, the mechanisms underlying the protective effects of SJP on cardiovascular disease have not yet been elucidated clearly, especially its relationship with the gut microbiota. AIM OF THE STUDY This study aimed to investigate the cardioprotective effect of SJP against isoproterenol-induced acute myocardial infarction (AMI) by integrating the gut microbiome and metabolome. METHODS A rat model of AMI was generated using isoproterenol. Firstly, the effect of antibiotic (ABX) treatment on the blood absorption and excretion of the main components of SJP were studied. Secondly, 16S rRNA sequencing and untargeted metabolomics were used to discover the improvement of SJP treatment on gut microbiota and host metabolism in AMI rats. Finally, targeted metabolomics was used to verify the effects of SJP treatment on host metabolism in AMI rats. RESULT The results showed that ABX treatment could affect the blood absorption and fecal excretion of the main active components of SJP. At the same time, SJP can restore the richness and diversity of gut microbiota, and multiple gut microbiota (including Jeotgalicoccus, Lachnospiraceae, and Blautia) are significantly associated with fatty acids. Untargeted metabolomics also found that SJP could restore the levels of various fatty acid metabolites in serum and cecal contents (p < 0.01, FC > 1.5 and VIP >1). Targeted metabolomics further confirmed that 41, 21, and 39 fatty acids were significantly altered in serum, cecal contents, and heart samples, respectively. Interestingly, these fatty acids belong to the class of eicosanoids, and SJP can significantly downregulate these eicosanoids in AMI rats. CONCLUSION The results of this study suggest that SJP may exert its cardioprotective effects by remodeling the gut microbiota and host fatty acid metabolism.

Abstract
BACKGROUND Many studies have shown effective protection from myocardial ischemia-reperfusion injury (MIRI) in animal models, but few, if any, treatments have yielded a substantial reduction in clinical. Several studies showed significant therapeutic effects for the Chinese patent medicine Suxiao Jiuxin Pill (SJP) in MIRI, although the specific molecular mechanisms remain undefined. Recently, increasing evidence indicates an important role for m6A modification in autophagy regulation in MIRI, and SJP has not been investigated in this regard. METHODS In vivo experiments were performed in a Wistar rat MIRI model. In vitro assays were conducted in hypoxia/reoxygenation (H/R)-treated H9c2 cells. H9c2 cells with ALKBH5 and GSK3β silencing were constructed by lentivirus transfection. TUNEL and Annexin V/PI assays were carried out for apoptosis detection. Then, m6A modification was detected with the EpiQuik m6A RNA methylation quantification kit, and GFP-RFP-LC3B was used to observe dynamic changes in autophagy. The autophagosome structure was assessed by Transmission electron microscopy. qPCR and immunoblot were performed for mRNA and protein analyses, receptively. RESULTS SJP significantly mitigated MIRI in rats, reducing infarct size and myocardial apoptosis, and improving left ventricular function. In addition, SJP inhibited autophagy through the GSK3β/mTOR pathway in MIRI rats. In cultured H9c2 cells, SJP significantly inhibited H/R- related apoptosis and autophagic activity through the GSK3β/mTOR pathway. Additionally, SJP enhanced ALKBH5 expression in H/R cardiomyocytes, which is important in impaired m6A modification. Interestingly, ALKBH5 knockdown enhanced autophagy and apoptosis in H/R-induced cells, whereas SJP reversed these effects. Further experiments showed that autophagic activity and apoptosis enhanced by ALKBH5 deficiency are GSK3β/mTOR pathway dependent in H/R-treated H9c2 cells. After SJP administration the above effects were alleviated, suggesting SJP inhibited autophagy through the ALKBH5/GSK3β/mTOR pathway in H/R-induced cardiomyocytes. These effects of SJP were common to its two main constituents, including tetra-methylpyrazine (TMP) and borneol (BOR). CONCLUSION SJP improves MIRI in rats and alleviates autophagy and apoptosis in H9c2 cells through the ALKBH5/GSK3β/mTOR pathway, thanks to its two major constituents TMP and BOR.

Kinetic Characteristics of Curcumin and Germacrone in Rat and Human Liver Microsomes: Involvement of CYP Enzymes. Molecules 2022; 27:molecules27144482. [PMID: 35889364 PMCID: PMC9317718 DOI: 10.3390/molecules27144482] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2022] [Revised: 07/03/2022] [Accepted: 07/06/2022] [Indexed: 02/05/2023] Open
Abstract
Curcumin and germacrone, natural products present in the Zingiberaceae family of plants, have several biological properties. Among these properties, the anti-NSCLC cancer action is noteworthy. In this paper, kinetics of the two compounds in rat liver microsomes (RLMs), human liver microsomes (HLMs), and cytochrome P450 (CYP) enzymes (CYP3A4, 1A2, 2E1, and 2C19) in an NADPH-generating system in vitro were evaluated by UP-HPLC–MS/MS (ultrahigh-pressure liquid chromatography–tandem mass spectrometry). The contents of four cytochrome P450 (CYP) enzymes, adjusting by the compounds were detected using Western blotting in vitro and in vivo. The t1/2 of curcumin was 22.35 min in RLMs and 173.28 min in HLMs, while 18.02 and 16.37 min were gained for germacrone. The Vmax of curcumin in RLMs was about 4-fold in HLMs, meanwhile, the Vmax of germacrone in RLMs was similar to that of HLMs. The single enzyme t1/2 of curcumin was 38.51 min in CYP3A4, 301.4 min in 1A2, 69.31 min in 2E1, 63.01 min in 2C19; besides, as to the same enzymes, t1/2 of germacrone was 36.48 min, 86.64 min, 69.31 min, and 57.76 min. The dynamic curves were obtained by reasonable experimental design and the metabolism of curcumin and germacrone were selected in RLMs/HLMs. The selectivities in the two liver microsomes differed in degradation performance. These results meant that we should pay more attention to drugs in clinical medication–drug and drug–enzyme interactions.
