Abstract
Toosendanin (TSN) is the main active compound derived from Melia toosendan Sieb et Zucc with various bioactivities. However, liver injury was observed in TSN limiting its clinical application. Lipid metabolism plays a crucial role in maintaining cellular homeostasis, and its disruption is also essential in TSN-induced hepatotoxicity. This study explored the hepatotoxicity caused by TSN in vitro and in vivo. The lipid droplets were significantly decreased, accompanied by a decrease in fatty acid transporter CD36 and crucial enzymes in the lipogenesis including ACC and FAS after the treatment of TSN. It was suggested that TSN caused lipid metabolism disorder in hepatocytes. TOFA, an allosteric inhibitor of ACC, could partially restore cell survival via blocking malonyl-CoA accumulation. Notably, TSN downregulated the LXRα/Lipin1/SREBP1 signaling pathway. LXRα activation improved cell survival and intracellular neutral lipid levels, while SREBP1 inhibition aggravated the cell damage and caused a further decline in lipid levels. Male Balb/c mice were treated with TSN (5, 10, 20 mg/kg/d) for 7 days. TSN exposure led to serum lipid levels aberrantly decreased. Moreover, the western blotting results showed that LXRα/Lipin1/SREBP1 inhibition contributed to TSN-induced liver injury. In conclusion, TSN caused lipid metabolism disorder in liver via inhibiting LXRα/Lipin1/SREBP1 signaling pathway.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Rosmarinic acid (RA), a natural polyphenol abundant in numerous herbal remedies, has been attracting growing interest owing to its exceptional ability to protect the liver. Toosendanin (TSN), a prominent bioactive compound derived from Melia toosendan Siebold & Zucc., boasts diverse pharmacological properties. Nevertheless, TSN possesses remarkable hepatotoxicity. Intriguingly, the potential of RA to counteract TSN-induced liver damage and its probable mechanisms remain unexplored. AIM OF THE STUDY This study is aimed at exploring whether RA can alleviate TSN-induced liver injury and the potential mechanisms involved autophagy. MATERIALS AND METHODS CCK-8 and LDH leakage rate assay were used to evaluate cytotoxicity. Balb/c mice were intraperitoneally administered TSN (20 mg/kg) for 24 h after pretreatment with RA (0, 40, 80 mg/kg) by gavage for 5 days. The autophagic proteins P62 and LC3B expressions were detected using western blot and immunohistochemistry. RFP-GFP-LC3B and transmission electron microscopy were applied to observe the accumulation levels of autophagosomes and autolysosomes. LysoTracker Red and DQ-BSA staining were used to evaluate the lysosomal acidity and degradation ability respectively. Western blot, immunohistochemistry and immunofluorescence staining were employed to measure the expressions of JAK2/STAT3/CTSC pathway proteins. Dual-luciferase reporter gene was used to measure the transcriptional activity of CTSC and RT-PCR was used to detect its mRNA level. H&E staining and serum biochemical assay were employed to determine the degree of damage to the liver. RESULTS TSN-induced damage to hepatocytes and livers was significantly alleviated by RA. RA markedly diminished the autophagic flux blockade and lysosomal dysfunction caused by TSN. Mechanically, RA alleviated TSN-induced down-regulation of CTSC by activating JAK2/STAT3 signaling pathway. CONCLUSION RA could protect against TSN-induced liver injury by activating the JAK2/STAT3/CTSC pathway-mediated autophagy and lysosomal function.

Abstract
In recent years, immunosuppressants have shown significant success in the treatment of autoimmune diseases. Therefore, there is an urgent need to develop additional immunosuppressants that offer more options for patients. Toosendanin has been shown to have immunosuppressive activity in vitro as well as effects on autoimmune hepatitis (AIH) in vivo. Toosendanin did not induce apoptosis in activated T-cells and affect the survival rate of naive T-cells. Toosendanin did not affect the expression of CD25 or secretion of IL-2 by activated T-cells, and not affect the expression of IL-4 and INF-γ. Toosendanin did not affect the phosphorylation of STAT5, ERK, AKT, P70S6K. However, toosendanin inhibited proliferation of anti-CD3/anti-CD28 mAbs-activated T-cells with IC50 of (10 ± 2.02) nM. Toosendanin arrested the cell cycle in the G0/G1 phase, significantly inhibited IL-6 and IL-17A secretion, promoted IL-10 expression, and inhibited the P38 MAPK pathway. Finally, toosendanin significantly alleviated ConA-induced AIH in mice. In Summary, toosendanin exhibited immunosuppressive activity in vivo and in vitro. Toosendanin inhibits the proliferation of activated T-cells through the P38 MAPK signalling pathway, significantly suppresses the expression of inflammatory factors, enhances the expression of anti-inflammatory factors, and effectively alleviates ConA-induced AIH in mice, suggesting that toosendanin may be a lead compound for the development of novel immunomodulatory agents with improved efficacy and reduced toxicity.

Abstract
Toosendanin (TSN) is the main active component in the traditional herb Melia toosendan Siebold & Zucc, which exhibits promising potential for development due to its diverse pharmacological properties. However, the hepatotoxicity associated with TSN needs further investigation. Previous research has implicated autophagy dysregulation in TSN-induced hepatotoxicity, yet the underlying mechanisms remain elusive. In this study, the mechanisms of signal transducer and activator of transcription 3 (STAT3) in TSN-induced autophagy inhibition and liver injury were explored using Stat3 knockout C57BL/6 mice and HepG2 cells. TSN decreased cell viability, increased lactate dehydrogenase (LDH) production in vitro, and elevated serum aspartate transaminase (AST) and alanine aminotransferase (ALT) levels as well as liver lesions in vivo, suggesting TSN had significant hepatotoxicity. TSN inhibited Janus kinase 2 (JAK2)/STAT3 pathway and the expression of cathepsin C (CTSC). Inhibition of STAT3 exacerbated TSN-induced autophagy inhibition and hepatic injury, whereas activation of STAT3 attenuated these effects of TSN. Mechanistically, STAT3 transcriptionally regulated the level of CTSC gene, which in turn affected autophagy and the process of liver injury. TSN-administered Stat3 knockout mice showed more severe hepatotoxicity, CTSC downregulation, and autophagy blockade than wildtype mice. In summary, TSN caused hepatotoxicity by inhibiting STAT3/CTSC axis-dependent autophagy and lysosomal function.

Abstract
The fall armyworm, Spodoptera frugiperda, is a destructive agricultural pest that seriously threatens global food security. Insecticide resistance of this pest has gradually formed in recent years due to improper usage, and alternative methods are badly needed. Toosendanin (TSN) is a botanical compound with broad-spectrum insecticidal activities against many pests. However, the effects of TSN on S. frugiperda are still unclear. In this study, the growth inhibition phenomenon, including weight loss and prolonged developmental duration, in the larvae with TSN exposure was clearly observed. Compared to the control group, a total of 450 and 3314 differentially expressed genes (DEGs) were identified by RNA-Seq in the larvae groups treated with 10 and 20 mg/kg TSN, respectively. Furthermore, the DEGs involved in the juvenile hormone and ecdysone signal pathways and downstream processes, including detoxifying enzyme genes, chitin synthesis and metabolism genes, and cuticular protein genes, were found. Our findings suggest that TSN regulates the expression of key genes in juvenile hormone and ecdysone signal pathways and a series of downstream processes to alter the hormone balance and cuticle formation and eventually inhibit larval growth, which laid the foundation for the molecular toxicological mechanism research of TSN on S. frugiperda larvae.

Abstract
BACKGROUND Extensive deposition of extracellular matrix (ECM) in idiopathic pulmonary fibrosis (IPF) is due to hyperactivation and proliferation of pulmonary fibroblasts. However, the exact mechanism is not clear. OBJECTIVE This study focused on the role of CTBP1 in lung fibroblast function, elaborated its regulation mechanism, and analyzed the relationship between CTBP1 and ZEB1. Meanwhile, the antipulmonary fibrosis effect and its molecular mechanism of Toosendanin were studied. METHODS Human IPF fibroblast cell lines (LL-97A and LL-29) and normal fibroblast cell lines (LL-24) were cultured in vitro. The cells were stimulated with FCS, PDGF-BB, IGF-1, and TGF-β1, respectively. BrdU detected cell proliferation. The mRNA expression of CTBP1 and ZEB1 was detected by QRT-PCR. Western blotting was used to detect the expression of COL1A1, COL3A1, LN, FN, and α-SMA proteins. An animal model of pulmonary fibrosis was established to analyze the effects of CTBP1 silencing on pulmonary fibrosis and lung function in mice. RESULTS CTBP1 was up-regulated in IPF lung fibroblasts. Silencing CTBP1 inhibits growth factor-driven proliferation and activation of lung fibroblasts. Overexpression of CTBP1 promotes growth factor-driven proliferation and activation of lung fibroblasts. Silencing CTBP1 reduced the degree of pulmonary fibrosis in mice with pulmonary fibrosis. Western blot, CO-IP, and BrdU assays confirmed that CTBP1 interacts with ZEB1 and promotes the activation of lung fibroblasts. Toosendanin can inhibit the ZEB1/CTBP1protein interaction and further inhibit the progression of pulmonary fibrosis. CONCLUSION CTBP1 can promote the activation and proliferation of lung fibroblasts through ZEB1. CTBP1 promotes lung fibroblast activation through ZEB1, thereby increasing excessive deposition of ECM and aggravating IPF. Toosendanin may be a potential treatment for pulmonary fibrosis. The results of this study provide a new basis for clarifying the molecular mechanism of pulmonary fibrosis and developing new therapeutic targets.

Abstract
BACKGROUND Toosendanin (TSN) exhibits potent antitumor activity against various tumor cell lines. However, its efficacy against oral squamous cell carcinoma (OSCC) remains unknown. Here, we investigated the effects of TSN on OSCC cells in vitro and verified them in vivo using a patient-derived xenograft (PDX) model. METHODS The effect of TSN on OSCC cells was investigated by cytotoxicity assays and flow cytometry. The expression of proteins was detected by western blotting. An OSCC PDX model was constructed to further investigate the role of TSN in regulating the function of OSCC. RESULTS The cell viability of CAL27 and HN6 cells decreased as the concentration of TSN increased within the experimental range. Compared with controls, TSN at lower doses inhibited cell proliferation and induced apoptosis through S-phase cell cycle arrest. TSN inhibited OSCC cell proliferation by downregulating the STAT3 pathway through the inhibition of STAT3 phosphorylation. After successful construction of the OSCC PDX model with high pathological homology to the primary tumor and treatment with an intraperitoneal injection of TSN, we showed that TSN significantly reduced the tumor size of the PDX model mice without obvious toxicity. CONCLUSIONS Both in vitro and in vivo, TSN significantly inhibits the proliferation and promoted apoptosis of OSCC cells. Furthermore, TSN demonstrates potent inhibition of STAT3 phosphorylation, indicating its potential as a promising therapeutic agent for OSCC. Therefore, TSN holds great promise as a viable drug candidate for the treatment of OSCC.

Abstract
Toosendanin (TSN), extracted from Melia. toosendan Sieb.et Zucc. and Melia. azedarach L., has been developed into an ascaris repellent in China. However, with the improvement of public health protection, the incidence of ascariasis has been reduced considerably, resulting in limited medical application of TSN. Therefore, it is questionable whether this old ascaris repellent can develop into a drug candidate. Modern studies have shown that TSN has strong pharmacological activities, including anti-tumor, anti-botulinum, anti-viral and anti-parasitic potentials. It also can regulate fat formation and improve inflammation. These researches indicate that TSN has great potential to be developed into a corresponding medical product. In order to better development and application of TSN, the availability, pharmacodynamics, pharmacokinetics and toxicology of TSN are summarized systematically. In addition, this review discusses shortcomings in the current researches and provides useful suggestions about how TSN developed into a drug candidate. Therefore, this paper illustrates the possibility of developing TSN as a medical product, aimed to provide directions for the clinical application and further research of TSN.

Abstract
The fall armyworm, Spodoptera frugiperda, is a polyphagous pest worldwide and feeds on many grain and cash crops, which threatens the safety of agriculture and forestry production. Toosendanin (TSN) is a commercial insecticidal active ingredient used to manage various pests in the field and showed adverse effects against S. frugiperda, while the effects of TSN on the larval midguts are not yet known. In this study, the effects of 10 and 20 mg/kg TSN exposures on the larval midguts were analyzed. The structural changes of the larval midgut induced by TSN treatments were also determined by hematoxylin-eosin staining. Besides, TSN treatments also changed the enzyme activities of three digestive enzymes (α-amylase, lipase, and trypsin) and two detoxification enzymes (CarE and GST). A total of 2868 differentially expressed genes (DEGs) were identified by RNA-Seq in the larval midguts with 20 mg/kg TSN treatment, and the DEGs responsible for food digestion and detoxification were further examined. Our findings revealed the preliminary modes of action of TSN on the larval midguts of S. frugiperda, which provide a preliminary rationale for controlling S. frugiperda with TSN in the field.

Abstract
Toosendanin (TSN) is an active compound from the fruit of Melia toosendan Sieb et Zucc. TSN has been shown to have broad-spectrum anti-tumour activities in human cancers. However, there are still many gaps in the knowledge of TSN on canine mammary tumours (CMT). CMT-U27 cells were used to select the optimal acting time and best concentration of TSN to initiate apoptosis. Cell proliferation, cell colony formation, cell migration and cell invasion were analysed. The expression of apoptosis-related genes and proteins were also detected to explore the mechanism of action of TSN. A murine tumour model was established to detect the effect of TSN treatments. The results showed that TSN decreased cell viability of migration and invasion, altered CMT-U27 cell morphology, and inhibited DNA synthesis. TSN-induced cell apoptosis by upregulating BAX, cleaved caspase-3, cleaved caspase-9, p53 and cytochrome C (cytosolic) protein expression, and downregulating Bcl-2 and cytochrome C (mitochondrial) expression. In addition, TSN increased the mRNA transcription levels of cytochrome C, p53 and BAX, and decreased the mRNA expression of Bcl-2. Furthermore, TSN inhibited the growth of CMT xenografts by regulating the expression of genes and proteins activated by the mitochondrial apoptotic pathway. In conclusion, TSN effectively inhibited cell proliferation, migration and invasion activity, as well as induced CMT-U27 cell apoptosis. The study provides a molecular basis for the development of clinical drugs and other therapeutic options.

Abstract
BACKGROUND Although molecular targets such as HER2, TP53 and PIK3CA have been widely studied in esophageal cancer, few of them were successfully applied for clinical treatment. Therefore, it is urgent to discover novel actionable targets and inhibitors. Eukaryotic translational elongation factor 2 (eEF2) is reported to be highly expressed in various cancers. However, its contribution to the maintenance and progression of cancer has not been fully clarified. METHODS In the present study, we utilized tissue array to evaluate eEF2 protein expression and clinical significance in esophageal squamous cell carcinoma (ESCC). Next, we performed knockdown, overexpression, RNA-binding protein immunoprecipitation (RIP) sequence, and nascent protein synthesis assays to explore the molecular function of eEF2. Furthermore, we utilized compound screening, Surface Plasmon Resonance (SPR), Isothermal Titration Calorimetry (ITC) assay, cell proliferation and Patient derived xenograft (PDX) mouse model assays to discover an eEF2 inhibitor and assess its effects on ESCC growth. RESULTS We found that eEF2 were highly expressed in ESCC and negatively associated with the prognosis of ESCC patients. Knocking down of eEF2 suppressed the cell proliferation and colony formation of ESCC. eEF2 bond with the mRNA of Topoisomerase II (TOP1) and Topoisomerase II (TOP2) and enhanced the protein biosynthesis of TOP1 and TOP2. We also identified Toosendanin was a novel inhibitor of eEF2 and Toosendanin inhibited the growth of ESCC in vitro and in vivo. CONCLUSIONS Our findings show that Toosendanin treatment suppresses ESCC growth through targeting eEF2 and regulating downstream TOP1 and TOP2 biosynthesis. eEF2 could be supplied as a potential therapeutic target in the further clinical studies.

Abstract
Toosendanin (TSN) is the main active compound of Melia toosendan Sieb et Zucc with various bioactivities. In this study, we investigated the role of ferroptosis in TSN-induced hepatotoxicity. The characteristic indicators of ferroptosis were detected including reactive oxygen species (ROS), lipid-ROS, glutathione (GSH), ferrous ion and the expression of glutathione peroxidase 4 (GPX4), which showed that TSN caused ferroptosis in hepatocytes. The results of qPCR analysis and western blotting assay showed that TSN-induced activation of protein kinase R-like endoplasmic reticulum kinase (PERK)- eukaryotic initiation factor 2 α subunit (eIF2α)- activation transcription factor 4 (ATF4) signaling pathway resulted in increasing activation transcription factor 3 (ATF3) expression, which upregulated the expression of transferrin receptor 1 (TFRC). Furthermore, TFRC mediated iron accumulation leading to ferroptosis in hepatocytes. To clarify whether TSN triggered ferroptosis in vivo, male Balb/c mice were treated with the different doses of TSN. The results of hematoxylin-eosin (H&E) staining, 4-hydroxynonenal (4-HNE) staining, malondialdehyde (MDA) content and the protein expression of GPX4 showed that ferroptosis contributed to TSN-induced hepatotoxicity. Iron homeostasis relative protein and PERK- eIF2α- ATF4 signaling pathway also involved in hepatotoxicity of TSN in vivo.

Abstract
Toosendanin (TSN) is a natural anti-cancer compound that is isolated from the traditional Chinese herbal Melia toosendan Sieb et Zucc. However, the research effect of TSN in the treatment of Triple negative breast cancer (TNBC) is still far from ideal. In this work, we investigated TSN and its derivatives in terms of their actions against MDA-MB-231 and HCC1806 TNBC cell lines. The results indicated that TSN and its derivative 11 showed excellent antitumor activity. Preliminary mechanistic studies showed that both compounds TSN and 11 induced S-phase arrest and G2/M phase cell number decrease in HCC1806 cells. Also, TSN and 11 significantly reduced the protein level of the well-known cancer suppressor gene p53, reduced the phosphorylation of AKT and ERK, and also induced the accumulation of phosphorylated p38 and p21.

Abstract
Disruption of the balance between osteoclasts and osteoblasts could lead to bone diseases including osteoporosis. It's well known that RANKL-RANK signaling plays a vital role in activating osteoclasts. Herein, we explored the therapeutic effects of toosendanin (TSN) in osteoporosis, showing that TSN attenuated RANKL-stimulated osteoclastogenesis and osteoclast-specific gene expression in vitro. Bioinformatics predicted that TSN could interfere p38 subunits and regulate the MAPK cascade, and we further verified and demonstrated that TSN significantly inhibited RANKL-induced p38 signaling through western blot. In ovariectomized mouse model, TSN effectively inhibited the formation of TRAP-positive osteoclasts and exhibited protective effect against bone loss. Altogether, these data indicate that TSN targeted p38 activation to inhibit osteoclastogenesis, suggesting the possible therapeutic use of TSN in osteoporosis in the future.

Abstract
BACKGROUND Cisplatin (DDP) resistance is prevalent in ovarian cancer (OC) patients and contributes to the poor prognosis. Therefore, it is of great significance to develop new agent to intervene and even reverse DDP resistance in OC. Toosendanin (TSN), a triterpenoid extracted from the bark or fruits of Melia toosendan Sieb et Zucc, has been proved to possess significant antitumor activities. However, the efficacy of TSN on DDP resistance in OC has not been reported yet. PURPOSE The aim of this study is to investigate the effects of TSN on DDP resistance in OC and explore the molecular mechanism in vitro and in vivo. METHODS Human OC cell line (SKOV3) and DDP-resistant cell line (SKOV3/DDP) were used. Cell proliferation was measured by CCK-8 and colony formation assay. Annexin V/PI double staining and hoechst 33342 nuclear staining were employed to detect cell apoptosis. Transwell and wound-healing assay were used to determine the invasion and migration potential of cells respectively. Quantitative real-time PCR (qPCR) and western blotting were performed to detect the expression of molecules related to miR-195/ERK/β-catenin pathway. The effects and mechanism of TSN on DDP resistance of OC in vivo was investigated using xenograft model, TUNEL staining assay and immunohistochemistry. RESULTS TSN improved the DDP sensitivity of SKOV3/DDP cells in vitro and in vivo, reflected in promoting inhibition of proliferation, invasion, migration and epithelial mesenchymal transformation (EMT) as well as induction of apoptosis by DDP. TSN could modulate the miR-195/ERK/β-catenin axis by upregulating the miR-195-5p expression and then suppressing ERK/GSK3β/β-catenin pathway which were activated in SKOV3/DDP cells. Moreover, co-treatment of β-catenin pathway activator LiCl or miR-195-5p silencing partially recovered the DDP resistance which was previously repressed by TSN. CONCLUSION Both in vitro and in vivo data demonstrated that TSN could reduce DDP resistance in OC through regulating the miR-195/ERK/β-catenin pathway, highlighting the potential of TSN as an effective agent for favoring overcoming clinical DDP resistance in OC.

Abstract
Colorectal cancer (CRC) is one of the most common gastrointestinal cancers worldwide. This complex and often fatal disease has a high mortality rate. The Hedgehog (Hh) signaling pathway is crucial in CRC. Many studies have indicated that Shh is overexpressed in cancer stem cells (CSCs), and shh overexpression is positively correlated with CRC tumorigenesis. New drugs that kill CRC cells through the Hh pathway are needed. Toosendanin (TSN), a natural triterpenoid saponin extracted from the bark or fruit of Melia toosendan Sieb. et Zucc, can inhibit various tumors. Here, we investigated the effects of TSN in CRC and explored the possible targets and mechanisms. Shh-Light Ⅱ cells were treated with TSN and tested by dual luciferase reporter assays to determine the relationship with the Hh pathway. Cell Counting Kit-8 (CCK-8) assays were used to test the inhibitory effects of TSN on CRC cells. The expression of Hh components after TSN treatment was detected using western blots and quantitative reverse transcription polymerase chain reaction. Cellular thermal shift assays confirmed the targets of TSN. The same effects of TSN on xenograft tumor growth were investigated in vivo. The average weight, volume of the finally resected tumor, and the expression of Shh in the TSN-treated groups were significantly lower than those of the control group. This result strongly suggested that TSN administration inhibited CRC growth in vivo. Our research preliminarily demonstrated that the target of TSN was Shh and that TSN inhibits CRC cell growth by inhibiting the Hh pathway, identifying a new anticancer molecular mechanism of TSN in CRC.

Abstract
Background Triple-negative breast cancer (TNBC) is a highly aggressive subtype of breast cancer that develops resistance to chemotherapy frequently. Autophagy has been reported as a pro-survival response to chemotherapeutic drugs in TNBC, and suppression of autophagy can be a strategy to overcome drug resistance. Methods The efficacy of toosendanin (TSN) in blocking autophagy flux was measured by western blot analysis of autophagy markers, and the fluorescent imaging of RFP-GFP-LC3 probe. The co-localization of autophagosomes and lysosomes was analyzed by fluorescent imaging. Then, lysosome function was determined by measuring the lysosomal pH value and the activity of lysosomal hydrolytic proteases. For in vitro study, human triple-negative breast cancer MDA-MB-231 and MDA-MB-436 cell lines were used for evaluating the anti-proliferative effect. For in vivo study, the RFP-GFP-LC3 MDA-MB-231 xenograft nude mice received intraperitoneal injection of irinotecan (10 mg/kg), TSN (0.5 mg/kg) or a combination, and the autophagy activity and cell apoptosis were determined in tumor tissue. The degree of pathological injury of tissue was evaluated by liver index. Results The natural autophagy inhibitor TSN, a triterpenoid extracted from Melia toosenda Sieb. et Zucc, potently inhibited late-stage autophagy in TNBC cells. This effect was achieved via elevating lysosome pH rather than blocking the fusion of autophagosomes and lysosomes. We further investigated the effects of TSN on the in vitro and in vivo TNBC models, in combination with chemotherapeutic drug irinotecan (or its active metabolite 7-ethyl-10-hydroxycamptothecin), a topoisomerase I inhibitor showing therapeutic potential for TNBC. The data showed that TSN blocked 7-ethyl-10-hydroxycamptothecin (SN-38)/irinotecan-induced protective autophagy, and significantly induced apoptosis in TNBC cells and tumor xenograft models when compared to SN-38/irinotecan alone group.

Abstract
Toosendanin (TSN) is a crucial component from Toosendan Fructus with a promising anti-tumor capacity. It is also the primary suspect hepatotoxic component of Toosendan Fructus. However, the mechanisms underlying TSN-induced liver injury are still largely unknown. In present study, we evaluated the hepatotoxicity of TSN on zebrafish and explored the role of inflammation, autophagy, and apoptosis in TSN-induced hepatotoxicity. We found that TSN treatment decreased the area and fluorescence intensity of zebrafish liver in time- and dose-dependent manners at nonlethal concentrations. The ALT and AST activities were increased after TSN treatment. Severe cytoplasmic vacuolation and nuclear shrank were found in the liver of TSN-treated zebrafish. The expression profile of genes demonstrated that inflammation, autophagy and apoptosis pathways were involved in TSN-induced hepatotoxicity. Our study demonstrated for the first time that TSN treatment gave rise to liver injury in zebrafish, and inflammation, autophagy, apoptosis played a role in TSN-induced hepatotoxicity.

Abstract
BACKGROUND Toosendanin (TSN) is a triterpenoid compound mainly used as an ascaris repellant. Recent studies have shown that it possesses antitumor effects in many types of tumor cells. However, the effects of TSN on glioma cells have rarely been reported. METHODS Different assays were performed to investigate the effects of TSN on the different glioma cell lines including U87MG and LN18. The assays included colony formation, wound healing, and transwell assays. Furthermore, Hoechst 33342 staining, flow cytometry, and western blotting analysis were performed to investigate the apoptotic activities of TSN. Finally, the results were confirmed using a xenograft tumor model that comprised of nude mice. RESULTS In vitro, the CCK-8 and colony formation assays showed that TSN effectively inhibited glioma cell proliferation. Moreover, the inhibitory effects on glioma cell migration and invasion were demonstrated through the wound healing and transwell assays, respectively. Hoechst 33342 staining, flow cytometry, and western blotting assays demonstrated the significant effect of TSN in the apoptosis induction of glioma cells. Furthermore, the anti-glioma effect of TSN was exerted through the inhibition of the PI3K/Akt/mTOR signaling pathways as demonstrated by western blotting analysis. In addition, the effects of TSN on glioma cell viability, apoptosis, cell cycle arrest, migration, and invasion were reversed by 740Y-P, a PI3K activator. Finally, the mouse xenograft model confirmed the suppressive effect of TSN on tumor growth in vivo. CONCLUSION Our results suggest that TSN is a promising chemotherapeutic drug for patients with glioma.

Abstract
Toosendanin (TSN) is a triterpenoid extracted from the bark or fruits of Melia toosendan Sieb et Zucc, which is a traditional Chinese medicine and mainly grows in China and India. TSN has been verified to possess antitumor activities on various human cancers, whereas the effects of TSN on ovarian cancer (OC) has not been reported yet. Here, TSN was shown to significantly inhibit proliferation of SKOV3 and OVCAR3 cell lines in a dose- and time-dependent manner. Treatment of OC cells with TSN resulted in colony formation reduction, S and G2/M phase arrest, cell apoptosis, and dramatic decrease in mitochondrial membrane potential. Furthermore, TSN suppressed invasion and migration of OC cells. Research on molecular mechanism indicated that the above efficacy of TSN was associated with decreased expression of survivin, PARP-1, Bcl-2, Bcl-xl, caspase-3, caspase-9, MMP-2 and MMP-9 and increased expression of cleaved PARP-1, Bax, cleaved caspase-3 and cleaved caspase-9. Finally, in vivo results showed that TSN suppressed OC xenograft tumor growth by inducing apoptosis and regulating the related protein expression levels of SKOV3 cells in transplanted tumors. Taken together, our data provide new insights into TSN as a potentially effective reagent against human OC through caspase-dependent mitochondrial apoptotic pathway.

Abstract
Drug-induced liver injury (DILI) is a major side effect, sometimes can't be exactly evaluated by current approaches partly as the covalent modification of drug or its reactive metabolites (RMs) with proteins is a possible reason. In this study, we developed a rapid, sensitive, and specific analytical method to assess the hepatotoxicity induced by drug covalently modified proteins based on the quantification of the modified amino acids using toosendanin (TSN), a hepatotoxic chemical, as an example. TSN RM-protein adducts both in rat liver and blood showed good correlation with the severity of hepatotoxicity. Thus, TSN RM-protein adducts in serum can potentially serve as minimally invasive biomarkers of hepatotoxicity. Meanwhile, large-scale chemical proteomics analysis showed that at least 84 proteins were modified by TSN RMs in rat liver, and the bioinformatics analysis revealed that TSN might induce hepatotoxicity through multi-target protein-protein interaction especially involved in energy metabolism. These findings suggest that our approach may serve as a valuable tool to evaluate DILI and investigate the possible mechanism, especially for complex compounds.

Abstract
Objective: To investigate the relationship between toosendanin(TSN) and CTP synthase(CTPS) cytoophidium formation in gastric cancer MKN-45 cells. Methods: In this study, the experimental material is MKN-45 human gastric cancer cells. It contains 7 treatment groups of 0, 20, 40, 60, 80, 100, and 120 nmol/L TSN. Each group was treated in triplex privately for 24、48 and 72 hours. Cell counting kit-8 (CCK8) was used to detect the inhibitory effect of TSN on the proliferation of MKN-45 cells. After immunofluorescence detection, the morphology of CTPS cells was observed by a laser confocal microscope. The effect of TSN on MYC gene expression was detected by qRT-PCR. In addition, it contains 2 treatment groups of 1 mmol/L DON and 1 mmol/L MPA, each group was treated in triplex privately for 6 hours and then the cytoophidium morphology was detected by immunofluorescence. Results: The results of immunofluorescence showed that CTPS formed a filamentous cytoophidium structure after treating MKN-45 cells with 1 mmol/L DON and 1 mmol/L MPA, which means that the cells have the ability to form CTPS cytoophidium; The cell proliferation rate of TSN treatment group was significantly lower than that of 0 nmol / L TSN group (P<0.01); Immunofluorescence results showed that CTPS cytoophidium was the most abundant in MKN-45 cells after treated with 80 nmol/L TSN for 72 h. The results of qRT-PCR showed that MYC expression in cells was significantly decreased after treated with 80 nmol/L TSN for 24 h (P<0.05), and MYC expression was significantly increased after 48 h (P<0.01), and then decreased. Conclusion: Toosendanin may affect intracellular cytoophidium assembling by regulating the expression of MYC.

Abstract
Toosendanin (TSN), as an important Chinese traditional insecticide, has been registered and commercialized in China. In this report, the residual analytical methods, residue dynamics and final residues of TSN in tobacco, cabbage and soil under field condition were studied by IC-ELISA and HPLC. The sensitivity, precision and repeatability of IC-ELISA method were more suitable in comparison with HPLC for the demand of TSN residue analysis. Using IC-ELISA, the half-lives (t1/2) of TSN were found to be 1.30 days in cabbage, 1.70 days in tabacco and 0.71 days in soil, respectively. At the recommended dose, the final residues of TSN detection by IC-ELISA was 0.009 mg·kg-1 in cabbage and 0.043 mg·kg-1 in tobacco, as well as was not detected in soil. Therefore, TSN is easily degradable, and IC-ELISA could be a convenient and supplemental analytical tool for monitoring TSN residue in crops and environment.

Abstract
Toosendanin (TSN), which is extracted from the root bark of Melia toosendan Siebold and Zuccarini, has multiple modes of action against insects. Especially, this compound has a potent stomach poisoning activity against several lepidoptera pests. In this paper, the signs of toxicity, digestive enzymes activity, the histopathological changes and immuno-electron microscopic localization of TSN in the midgut epithelium of Mythimna separate Walker larvae were investigated for better understanding its action mechanism against insects. The bioassay results indicated that TSN has strong stomach poisoning against the fifth-instar larvae of M. separata (LC50 = 252.23 μg/mL). The typical poisoned symptom were regurgitation and paralysis. Activities of digestive enzymes had no obvious changes after treatment with LC80 dose of TSN. The midgut epithelial cells of insect were damaged by TSN, showing the degeneration of microvilli, hyperplasia of smooth endoplasmic reticulum and condensation of chromatin. Immunohistochemical analysis revealed that the gold particles existed on the microvilli of columnar cells and goblet cells, and gradually accumulated with the exacerbation of poisoning symptoms, showing that TSN targets on the microvilli of the midgutcells. Therefore, TSN acts on digestive system and locates in the microvilli of midgutcells of M. separata.

Abstract
Africa Trypanosomiasis remains a serious health problem, but the approved drugs for this disease are so few that novel trypanocidal compounds are demanded. In search for trypanocidal principles from medicinal plants, we found MeOH extracts of Meliae Cortex with potent activity through the screening from about 300 kinds of methanolic extract. By bioassay-guided fractionation from this extract through the liquid-liquid partition and subsequent chromatographic technique using silica gel and ODS, finally we disclosed toosendanin (1) and its relatives as active principles. These active congeners showed not only potent trypanocidal activity but also little cytotoxicity to display the excellent selective index. Taking the isolated amount as well as trypanocidal activity into consideration, 1 was disclosed to be the responsible active principle in Meliae Cortex. Additionally, the derivatives of 1 were chemically prepared from 1 and bioactivity of them were also evaluated. Through the comparison with their trypanocidal activity among the isolated relatives and the synthesized derivatives of 1, the epoxide moiety was revealed to be essential for their potent trypanocidal activity. Furthermore, 3-O-acetyl group and 7-hydroxyl group were presumed to be important functional groups and introduction of methylpropionyl group into hemiacetal hydroxy moiety was clarified to enhance their typanocidal activity.

Abstract
Developing new drugs for killing colorectal cancer (CRC) cells is urgently needed. Here, we explored the antitumor effects of toosendanin (TSN) in CRC, as well as explored its antitumor mechanisms and direct targets. Cell proliferation and apoptosis were analyzed by CCK8, colony formation, real-time cell impedance and flow cytometry. The signaling pathway and Wnt activity were analyzed by Wnt luciferase activity assay, quantitative real-time PCR and western blot. The interaction between TSN and the κ-opioid receptor was analyzed by a molecular docking simulation. BALB/c nude mice were used to detect the effects of TSN on tumor growth in vivo. We found that TSN inhibited proliferation, induced G1 phase arrest and caused caspase-dependent apoptosis in both 5-FU-sensitive and 5-FU-resistant CRC cells. Moreover, TSN effectively inhibited CRC growth in vivo. In terms of the mechanism, TSN inhibited Wnt/β-catenin signaling in CRC cells, and the molecular docking results showed that TSN could bind to κ-opioid receptors directly. Additionally, TSN-induced apoptosis and β-catenin decline were both reversed by the selective κ-opioid receptor agonist U50,488H. Our data demonstrate that TSN-induced apoptosis in CRC cells is associated with the κ-opioid receptor/β-catenin signaling axis, and TSN has promising potential as an antitumor agent for CRC treatment.

Abstract
Toosendanin (TSN), a triterpenoid extracted from the bark of fruit of Melia toosendan Sieb et Zucc, has been proven to have various biological activities including anti-inflammatory activity. But its effects on experimental colitis remain unreported. Herein, we investigated the role and potential mechanisms of TSN in dextran sulfate sodium (DSS) induced colitis in mice. The results showed that, TSN reduced colitis-associated disease activity index (DAI), shortened colon length, and weakened the pathological damage of the colon tissues in murine colitis models. Further studies disclosed that, TSN inhibited the secretion of proinflammatory cytokines and oxidative stress, and suppressed M1 macrophage polarization and the activation of NLR family pyrin domain containing 3 (NLRP3) inflammasome, but upregulated HO-1/Nrf2 expression in murine colitis. In addition, TSN maintained intestinal barrier by regulating zonula occludens-1 (ZO-1) and occludin expression. In conclusion, our findings demonstrated that, TSN alleviates DSS-induced experimental colitis by inhibiting M1 macrophage polarization and regulating NLRP3 inflammasome and Nrf2/HO-1 signaling, and may provide a novel Chinese patent medicine for the treatment of murine colitis.

Abstract
BACKGROUND Toosendan Fructus is traditionally used as an insecticide or digestive tract parasiticide for treating digestive parasites in China. It is recorded to have little toxicity in Chinese Pharmacopoeia and has been found to cause severe liver injury during clinical practice. PURPOSE This study aims to identify candidate serum microRNAs (miRNAs) as potential toxicological biomarkers for reflecting the hepatotoxicity induced by toosendanin (TSN), which is the main toxic compound isolated from Toosendan Fructus METHODS: Alanine/aspartate aminotransferase (ALT/AST) activities detection and liver histological observation were performed to evaluate the liver injury induced by TSN or other hepatotoxicants in mice. miRNAs chip analysis and Real-time PCR assay were conducted to identify the altered miRNAs in serum from TSN-treated mice RESULTS: The results of serum ALT/AST and liver histological evaluation showed that TSN (10 mg/kg) induced hepatotoxicity in mice. The results of miRNAs chip showed that the expression of 81 serum miRNAs was obviously altered in mice treated with TSN for 12 h, and 22 of them have passed the further validation in serum from mice treated with TSN for both 6 h and 12 h. These 22 miRNAs were supposed to be the candidate toxicological biomarkers for TSN-induced hepatotoxicity with more sensitivity as compared to the alteration of AST or ALT activity. Moreover, the expression of miRNA-122-3p and mcmv-miRNA-m01-4-3p was not only increased in TSN-treated mice, but also increased in mice treated with other hepatotoxicants including acetaminophen (APAP), monocrotaline (MCT) and diosbuibin B (DB). Only the expression of serum miRNA-367-3p was increased in TSN-treated mice but not changed in the liver injury induced by APAP, MCT or DB CONCLUSION: miR-122-3p and mcmv-miRNA-m01-4-3p may be two commonly sensitive biomarkers for reflecting the hepatotoxicity induced by exogenous hepatotoxicants, and miR-367-3p may be a specific biomarker for reflecting the liver injury induced by TSN.

Abstract
Toosendanin (TSN) is a triterpenoid purified from the medicinal herb Melia toosendan Sieb. et Zucc and has been used as an insecticide for decades. Recent studies have attracted increasing interest of TSN due to its novel anti-cancer effect in diverse cancer models. The broad spectrum anti-cancer activity suggests that TSN inhibits multiple pathways/targets that are critical for cancer cell survival and proliferation. Our recent study indicated that TSN has anti-cancer effect in glioblastoma through induction of estrogen receptor β (ERβ) and p53. This review highlights the anti-cancer efficacy of TSN and provides proof-of-principle insight into the underlying mechanisms.
