Lin D, Wang S, Yang B, Li G. Ameliorative effect of Schisandrol B against Diosbulbin B-induced hepatotoxicity via inhibiting CYP3A4-mediated bioactivation. Toxicol Appl Pharmacol 2024; 492:117116. [PMID: 39357680 DOI: 10.1016/j.taap.2024.117116] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2024] [Revised: 09/26/2024] [Accepted: 09/27/2024] [Indexed: 10/04/2024]
Abstract
Diosbulbin B (DBB), the major component isolated from herbal medicine Dioscorea bulbifera L. (DBL), can trigger severe hepatotoxicity. The previous studies demonstrated that DBB-induced hepatotoxicity is closely relevant to the bioactivation mediated by CYP3A4 and subsequent generation of adducts with cellular proteins. Schisandrol B (SchB), the primary lignan ingredient in herbal medicine Schisandra chinensis (SC), is able to inhibit CYP3A activity. The objective of this study is to investigate the protective effect of SchB against hepatotoxicity induced by DBB and to explore the underlying mechanism. Biochemical and histopathological analysis demonstrated that SchB exerted dose-dependent protective effect against DBB-induced hepatotoxicity. In vitro metabolism assay showed that the formation of pyrrole-glutathione (GSH) conjugates of DBB was inhibited by SchB in a concentration dependent manner, suggesting SchB inhibited the bioactivation of DBB in vitro. Pharmacokinetic studies demonstrated that SchB enhanced Cmax and AUCs of DBB in mouse blood and liver, resulting in accelerating the accumulation of DBB in the circulation. In addition, pretreatment with SchB alleviated DBB-induced hepatic GSH depletion, obviously facilitated the excretion of DBB in urine, and reduced the urinary excretion of DBB-GSH conjugates, indicating that SchB affected absorption, distribution, metabolism, and excretion (ADME) of DBB by inhibiting the bioactivation of DBB in vivo. In conclusion, our findings demonstrated the amelioration of SchB against DBB-induced hepatotoxicity was correlated with the inhibition of CYP3A4-mediated bioactivation of DBB. Thus, the findings indicated that SchB may serve as a potential candidate drug for the treatment of DBB intoxication.

Abstract
Peculiarities of accumulation of nutrients in the leaves of Schisandra chinensis (Turcz.) Baill. and rhizosphere soil under the conditions of its continuous monoculture have been studied. Comparative analysis of the distribution of nutrients in the leaves of plants under different soil and climatic conditions revealed significant differences. It was found that plants grown on podzolic chernozem of Kolomyia State Forest Fund (Otyniia, Ukraine) were characterized by more intensive absorption of such nutrients as Ca, Si, P, Cu, Zn and Mg. The content of P, K, S, Mn was much higher in the foliar tissues of S. chinensis plants cultivated on the territory of the M. Gryshko National Botanical Garden (Kyiv, Ukraine) in the conditions of dark grey forest soil. The high ability of plants to accumulate and release Mg into the rhizosphere soil was revealed, which is fully consistent with the selective ability of plants to release mineral elements into the soil environment in accordance with their ecomorphotypes. At the same time, the amount of Ca in the rhizosphere soil decreased significantly at the end of the vegetative period, which could be explained, on the one hand, by the intensive influx of Ca into plant tissues and, on the other hand, by participation in chemical balancing processes to reduce manganese and nitrogen mobility in the soil. Barrier-free accumulation of Fe, Ca, Mg, Al elements in S. chinensis leaves was revealed, which should be taken into account when developing plant cultivation technology. The studies of allelopathy activity of vegetative and generative organs of plants and rhizosphere soil have shown that phenolic substances accumulate in small amounts in the soil under S. chinensis, which is a prerequisite for successful cultivation of this fruit vine in the Forest-Steppe zone of Ukraine under conditions of continuous long-term cultivation. The largest amount of phenolic substances was in the upper soil horizons, which gradually decreased with depth, which is consistent with the course of redox processes for the studied soil profiles. The pool of free amino acids of S. chinensis plants growing in different soil and climatic conditions was analyzed, the concentration of amino acids in the leaves was the most indicative. Evaluation of the quantitative and qualitative distribution of free amino acids in plant tissues serves as a diagnostic sign of plant sensitivity to soil and climatic conditions.

Study on the effect of active components of Schisandra chinensis on liver injury and its mechanisms in mice based on network pharmacology. Eur J Pharmacol 2021; 910:174442. [PMID: 34492285 DOI: 10.1016/j.ejphar.2021.174442] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2021] [Revised: 07/30/2021] [Accepted: 08/24/2021] [Indexed: 02/06/2023]
Abstract
The aim of this study was to analyze the active components of Schisandra chinensis on liver injury and its mechanism in mice by network pharmacology. The active components of S. chinensis were found through Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and their corresponding targets were predicted. The targets of liver injury were searched through Therapeutic Targets Database (TTD), DisGeNET and drugbank databases, and the Venn diagram was constructed to obtain the action targets. The "drug-active component-target" network and protein-protein interaction network (PPI) were constructed by using STRING database and Cytoscape software, and the key targets were further screened by the enrichment analysis of relevant KEGG pathways. Finally, a CCl4-induced mouse liver injury model was established to verify the efficacy and related targets of S. chinensis and clarify its mechanism. Eight active components and 56 related targets of S. chinensis were screened out based on their oral bioavailability (OB) and drug likeness (DL). Five targets of S. chinensis related to liver injury were found by using the Venn diagram. The key targets, namely Ptgs2 and Nos2 genes, were further screened out by constructing a PPI network, and Schisandrol B (SCB) was considered the key component most closely related to the liver injury in S. chinensis. The results indicate that SCB may play a role in the treatment of the CCl4-induced liver injury by down-regulating the expression of iNOS and COX-2, and regulating the expression of NF-κB and IL-17 signaling pathway to inhibit the expression of proinflammatory factors.

Pan MH, Zhu SR, Duan WJ, Ma XH, Luo X, Liu B, Kurihara H, Li YF, Chen JX, He RR. "Shanghuo" increases disease susceptibility: Modern significance of an old TCM theory. JOURNAL OF ETHNOPHARMACOLOGY 2019; 250:112491. [PMID: 31863858 DOI: 10.1016/j.jep.2019.112491] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/10/2019] [Revised: 12/16/2019] [Accepted: 12/17/2019] [Indexed: 02/08/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE "Shanghuo", a concept based on Traditional Chinese Medicine (TCM) theory, describes a status of Yin-Yang imbalance when Yang overwhelms Yin. The imbalance of Yin-Yang resembles the breaking of homeostasis and manifests by the impaired physiological functions, which leads to the onset, recurrence, and progression of diseases. Since ancient times, Chinese Materia Medica (CMM), such as herbal tea, has been applied as a treatment for "Shanghuo". AIM OF THE STUDY This review is aimed to describe the origin of "Shanghuo" from the Yin-Yang theory in TCM, as well as explore the relevance and correlations between "Shanghuo" and diseases susceptibility from the perspective of modern medicine. We also propose several strategies from CMM to improve the status of "Shanghuo" for the purpose of treating diseases. METHODS Systematic research of articles with keywords including Shanghuo, Yin-Yang, emotional stress and disease susceptibility was done by using the literature databases (Web of Science, Google Scholar, PubMed, CNKI). Related books, PhD and master's dissertations were also researched. Full scientific plant names were validated by "The Plant List" (www.theplantlist.org). RESULTS To date, a large number of publications have reported research on sub-health status, but studies about the theory or intervention of "Shanghuo" are rarely found. The articles we reviewed indicate that accumulated emotional stress is critical for the cause of "Shanghuo". As a status similar to sub-health, "Shanghuo" is also manifested by impaired physiological functions and decreased nonspecific resistance, which increase susceptibility to various diseases. What's more, some studies highlight the importance of TCM treatment towards "Shanghuo" in maintaining normal physiological functions, such as immunity, lipid metabolism and ROS clearance. CONCLUSIONS Researches on "Shanghuo" and its mechanism are every rare currently and are in need of investigation in the future. Studies on disease susceptibility recently are mostly about susceptible genes that relate to a few parts of people, however, for most of the people, accumulated emotional stress or other stressors is accountable for the susceptibility of diseases. Given that emotional stress plays an important factor in the causation of "Shanghuo", we reviewed the articles about this relevance and discussed the connection of "Shanghuo" with disease susceptibility in a novel perspective. In addition, we have reviewed the disease susceptibility model of restraint stress from its biochemical manifestation to application in CMM assessment. Although it would be a breakthrough in evaluating CMM efficacy of attenuating disease-susceptibility, understanding the comprehensive theory and establishing more models of "Shanghuo" would be required in further investigation.

Schisandra Lignan Extract Protects against Carbon Tetrachloride-Induced Liver Injury in Mice by Inhibiting Oxidative Stress and Regulating the NF- κB and JNK Signaling Pathways. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2017; 2017:5140297.

Abstract
Schisandra chinensis (S. chinensis) is a traditional Chinese herbal medicine widely used for the treatment of liver disease, whose main active components are lignans. However, the action mechanisms of the lignans in S. chinensis remain unclear. This study aimed to investigate the protective effect and related molecular mechanism of Schisandra lignan extract (SLE) against carbon tetrachloride- (CCl4-) induced acute liver injury in mice. Different doses of SLE at 50, 100, and 200 mg/kg were administered daily by gavage for 5 days before CCl4 treatment. The results showed that SLE significantly decreased the activities of serum ALT/AST and reduced liver pathologic changes induced by CCl4. Pretreatment with SLE not only decreased the content of MDA but increased SOD, GSH, and GSH-Px activities in the liver, suggesting that SLE attenuated CCl4-induced oxidative stress. The expression levels of inflammatory cytokines TNF-a, IL-1β, and IL-6 were decreased after oral administration of SLE, probably because lignans inhibited the NF-κB activity. Additionally, SLE also inhibited hepatocyte apoptosis by suppressing JNK activation and regulating Bcl-2/Bax signaling pathways. In conclusion, these results suggested that SLE prevented CCl4-induced liver injury through a combination of antioxidative stress, anti-inflammation, and antihepatocyte apoptosis and alleviated inflammation and apoptosis by regulating the NF-κB, JNK, and Bcl-2/Bax signaling pathways.

Abstract
HIV-1 reverse transcriptase (RT) is still an extremely attractive pharmaceutical target for the identification of new inhibitors possibly active on drug resistant strains. Medicinal plants are a rich source of chemical diversity and can be used to identify novel scaffolds to be further developed by chemical modifications. We investigated the ability of the main lignans from Schisandra chinensis (Turcz.) Baill. fruits, commonly used in Traditional Chinese Medicine, to affect HIV-1 RT functions. We purified 6 lignans from Schisandra chinensis fruits and assayed their effects on HIV-1 RT and viral replication. Among the S. chinensis fruit lignans, Schisandrin B and Deoxyschizandrin selectively inhibited the HIV-1 RT-associated DNA polymerase activity. Structure activity relationship revealed the importance of cyclooctadiene ring substituents for efficacy. In addition, Schisandrin B was also able to impair HIV-1 RT drug resistant mutants and the early phases of viral replication. We identified Schisandrin B and Deoxyschizandrin as new scaffold for the further development of novel HIV-1 RT inhibitors.

Abstract
To investigate the possible drug interaction, this study is designed to evaluate the ability of Schisandrin B (Sch B) to modulate cytochrome P450 3A activity (CYP3A) in vivo and to alter the pharmacokinetic profiles of CYP3A substrate (midazolam) in treated rats. Rats were repeated administered with physiological saline (negative control group), ketoconazole (75 mg/kg, positive control group) or varied doses of Sch B (experimental groups) for three consecutive days. Subsequently, changes in hepatic microsomal CYP3A activity and the pharmacokinetic profiles of midazolam and 1'-hydroxy midazolam in plasma were studied to evaluate CYP3A activity. The results indicated that Sch B significantly dose-dependently inhibited rat hepatic microsomal CYP3A activity with Ki value of 16.64 mg/kg and showed the characteristic of a noncompetitive inhibitor. Oral administration of Sch B for 3 days in rats produced significant effect on the pharmacokinetics of oral midazolam. Sch B resulted in a significant, dose-dependent increase in midazolam AUC0-∞ except at the dose of 2 mg/kg, while AUC0-∞ increased by 26.1% (8 mg/kg) and 60.6% (16 mg/kg), respectively. In the pharmacokinetic profiles of 1'-hydroxy midazolam, the significant, dose-dependent decrease in AUC0-∞ was observed except at the dose of 2 mg/kg, while AUC0-∞ reduced by 44.5% (8 mg/kg) and 49.2% (16 mg/kg), respectively. These results suggested that 3-day treatment of Sch B could increase concentration and oral bioavailability of drug metabolized by CYP3A. When the drug, consisting of Sch B, is used in the clinic for more than 3 days, the possible drug-drug interactions should be taken into consideration.
