Abstract
Background Liver cancer had become the sixth most common cancer. Nitidine chloride (NC) has demonstrated promising anti-HCC properties; however, further elucidation of its mechanism of action is necessary. Methods The anti-HCC targets of NC were identified through the utilization of multiple databases and ChIPs data analysis. The GO and KEGG analyses to determine the specific pathway affected by NC. The Huh 7 and Hep G2 cells were subjected to a 24-h treatment with NC, followed by evaluating the impact of NC on cell proliferation and cell cycle. The involvement of the p53/14-3-3 Sigma/CDK1 axis in HCC cells was confirmed by qPCR and WB analysis of the corresponding genes and proteins. Results The GO and KEGG analysis showed the targets were related to cell cycle and p53 signaling pathways. In vitro experiments showed that NC significantly inhibited the proliferation of HCC cells and induced G2/M phase arrest. In addition, qPCR and WB experiments showed that the expression of p53 in HCC cells increased after NC intervention, while the expression of 14-3-3 Sigma and CDK1 decreased. Conclusion NC can inhibit the proliferation of HCC cells and induce G2/M cell cycle arrest, potentially by regulating the p53/14-3-3 Sigma/CDK1 axis.

Abstract
The objective of this work to study the programmed cell death (PCD) in hematological tumor cells induced by nitidine chloride (NC) and bufalin (BF). Hematological tumor cells were exposed to various doses of NC and BF to measure the level of growth inhibition. While inverted microscope is used to observe cell morphology, western blot technique is used to detect apoptosis-related protein expression levels. The effects of NC and BF on hematological tumor cells were different. Although abnormal cell morphology could be seen under the inverted microscope, the western blot results showed that the two medicines induced PCD through different pathways. Drug resistance varied in intensity across distinct cells. THP-1, Jurkat, and RPMI-8226 each had half maximum inhibitory concentrations (IC50) of 36.23 nM, 26.71 nM, and 40.46 nM in BF, and 9.24 µM, 4.33 µM, and 28.18 µM in NC, respectively. Different hematopoietic malignancy cells exhibit varying degrees of drug resistance, and the mechanisms by which apoptosis of hematologic tumor cells is triggered by NC and BF are also distinct.

Abstract
Nitidine chloride (NC) is effective on cancer in many tumors, but its effect on bladder cancer (BC) is unknown. We conducted cell function experiments to verify the antineoplastic effect of NC on BC cell lines (5637, T24, and UM-UC-3) in vitro. Then, mRNAs of NC-treated and NC-untreated BC cells were extracted for mRNA sequencing. Differentially expressed genes (DEGs), expression analysis, and drug molecular docking were conducted to discover the target gene of NC. Finally, functional enrichment was analyzed to explore the underlying mechanisms. NC dramatically inhibited proliferation, migration, and invasion, and it induced apoptosis and arrested the S and G2/M phases of BC cell lines. Lymphocyte antigen 75 (LY75) appeared to be the target of NC. LY75 was highly expressed and had the ability to distinguish BC tissue from non-cancerous tissue. Then, drug molecular docking confirmed the targeting relationship between NC and LY75. Gene enrichment analysis showed that the downregulated genes, after being treated with NC, were mainly enriched in pathways relevant to cell pathophysiological processes. NC inhibits BC cell proliferation, migration, and invasion, induces apoptosis, and arrests cell cycles by downregulating the expression of LY75. This study provides molecular and theoretical bases for NC treatment of BC.

Abstract
Since multiple myeloma (MM) remains a cureless malignancy of plasma cells to date, it becomes imperative to develop novel drugs and therapeutic targets for MM. We screened a small molecule library comprising 3633 natural product drugs, which demonstrated that Nitidine Chloride (NC), an extract from traditional Chinese medicine Zanthoxylum nitidum. We used Surface Plasmon Resonance-High Performance Liquid Chromatography-Protein Mass Spectrometry (SPR-HPLC-MS), Cellular Thermal Shift Assay (CETSA), molecular docking, and SPR assay to identify the potential targets of NC, in which ABCB6 was the unique target of NC. The effects of ABCB6 on cellular proliferation and drug resistance were determined by CCK8, western blot, flow cytometry, site-mutation cells, transmission electron microscopy, immunohistochemistry staining and xenograft model in vitro and in vivo. NC induced MM cell death by promoting ferroptosis. ABCB6 is the direct target of NC. ABCB6 expression was increased in MM samples compared to normal controls, which was significantly associated with MM relapse and poor outcomes. VGSK was the inferred binding epitope of NC on the ABCB6 protein. In the ABCB6-mutated MM cells, NC did not display cancer resistance, implying the vital role of ABCB6 in NC's bioactivity. Moreover, the silencing of ABCB6 significantly inhibited MM cell growth. Mechanistically, the direct binding of NC to ABCB6 suppressed PI3K/AKT signaling pathway to promote ferroptosis. In conclusion, ABCB6 can be a potential therapeutic target and prognostic biomarker in MM, while NC can be considered a novel drug for MM treatment.

Abstract
BACKGROUND As the increasing mortality and incidence of lung cancer (LC), there is an urgent need to discover novel treatment agent. In this study, we aimed to investigate the anti-LC effects of nitidine chloride (NC), a small molecular compound extracted from Chinese herbal medicine, while detailing its underlying mechanisms. METHODS Cell viability was detected by MTT assays and five cell death inhibitors, including ferrostatin-1 (Fer-1), Z-VAD-FMK, necrostatin-1 (Nec-1), disulfiram (DSF) and IM-54 were used to explore the type of cell death induced by NC. The microscopic features of NC-induced pyroptosis were assessed by transmission electron microscopy (TEM) and the pyroptotic-related proteins such as caspase and gasdermin family, were examined by western blot. Network pharmacology was employed to predict the potential mechanisms of NC in lung cancer treatment. CETSA and DARTs were used to determine the activity of NC binding to targeted protein. Xenograft mice model was established to further investigate the inhibitory effect and mechanism of NC against LC. RESULTS The pyroptosis inhibitor (DSF) and apoptosis inhibitor (Z-VAD-FMK) but not IM-54, necrostatin-1, or Ferrostatin-1 rescued NC-induced cell death. Morphologically, H1688 and A549 cells treated with NC showed notably pyroptotic features, such as cell swelling and large bubbles emerging from the plasma membrane. Gasdermin E (GSDME) rather than GSDMC or GSDMD was cleaved in NC-treated H1688 and A549 cells with an increased cleavage of caspase 3. Combined with network pharmacology and molecule docking, PI3K/Akt signaling axis was predicted and was further verified by CETSA and DARTs assay. In addition, the activation of PI3K is able to rescue the pyroptosis induced by NC in vitro. In xenograft model of LC, NC significantly hindered the transduction of PI3K-AKT pathway, inducing pyroptosis of tumor. CONCLUSION Our data indicated that NC is a potential therapeutic agent for the treatment of LC via triggering GSDME-dependent pyroptosis.

Abstract
OBJECTIVE Nitidine chloride (NC), a natural small molecular compound from traditional Chinese herbal medicine zanthoxylum nitidum, has been shown to exhibit anti-tumor effect. However, its role in autoimmune diseases such as rheumatoid arthritis (RA) is unknown. Here, we investigate the effect of NC in controlling fibroblast-like synoviocytes (FLS)-mediated synovial inflammation and joint destruction in RA and further explore its underlying mechanism(s). METHODS FLSs were separated from synovial tissues obtained from patients with RA. Protein expression was analyzed by Western blot or immunohistochemistry. Gene expression was measured using quantitative RT-PCR. ELISA was used to measure the levels of cytokines and MMPs. Cell proliferation was detected using EdU incorporation. Migration and invasion were evaluated by Boyden chamber assay. RNA sequencing analysis was used to identify the target of NC. Collagen-induced arthritis (CIA) model was used to evaluate the in vivo effect of NC. RESULTS NC treatment reduced the proliferation, migration, invasion, and lamellipodia formation but not apoptosis of RA FLSs. We also demonstrated the inhibitory effect of NC on TNF-α-induced expression and secretion of IL-6, IL-8, CCL-2, MMP-1 and MMP-13. Furthermore, we identified KCNH1, a gene that encodes ether-à-go-go-1 channel, as a novel targeting gene of NC in RA FLSs. KCNH1 expression was increased in FLSs and synovial tissues from patients with RA compared to healthy controls. KCNH1 knockdown or NC treatment decreased the TNF-α-induced phosphorylation of AKT. Interestingly, NC treatment ameliorated the severity of arthritis and reduced synovial KCNH1 expression in mice with CIA. CONCLUSIONS Our data demonstrate that NC treatment inhibits aggressive and inflammatory actions of RA FLSs by targeting KCNH1 and sequential inhibition of AKT phosphorylation. Our findings suggest that NC might control FLS-mediated rheumatoid synovial inflammation and joint destruction, and be a novel therapeutic agent for RA.

Abstract
Background The development of novel and effective drugs for targeted human hepatocellular carcinoma still remains a great challenge. The alkaloid nitidine chloride (NC), a component of a traditional Chinese medicine, has been shown to have anticancer properties, but doses at therapeutic levels have unacceptable side effects. Here we investigate folic acid modified D-α-tocopheryl polyethylene glycol 1000 succinate (TPGS-FA) as a potential carrier for controlled delivery of the drug. Methods Synthesized TPGS-FA was characterized by FTIR, UV-visible and 1H NMR spectroscopy, and TPGS loaded with NC was evaluated for its ability to induce apoptosis in Huh7 cells by Annexin V/PI and MTT assays, and observed by laser scanning confocal microscopy and inverted phase contrast microscopy. Results TPGS-FA/NC complexes were prepared successfully, and were homogenious with a uniform size of ~ 14 nm diameter. NC was released from the TPGS-FA/NC complexes in a controlled and sustained manner under physiological conditions (pH 7.4). Furthermore, its cytotoxicity to hepatocarcinoma cells was greater than that of free NC. Conclusions TPGS-FA is shown to be useful carrier for drugs such as NC, and TPGS-FA/NC could potentially be a potent and safe drug for the treatment of hepatocellular carcinoma.

Abstract
Nitidine chloride (NC) possesses anticancer properties in various types of human malignancies. However, the effects of NC on lung cancer cells have not been elucidated. Moreover, the molecular mechanism of NC-involved antitumor activity is unclear. Therefore, we aimed to determine the biological effect of NC and the underlying molecular insights in lung cancer cells. The antineoplastic function of NC was assessed by MTT assays, Annexin V-FITC/PI apoptosis assay, wound healing analysis, and Transwell chamber migration and invasion assay in lung cancer cells. NEDD4 modulation was evaluated by western blotting assays of lung cancer cells after NC treatments. NEDD4 overexpression and downregulation were employed to validate the critical role of NEDD4 in the NC-mediated tumor suppressive effects. We found that NC suppressed cell viability, migration and invasion, but induced apoptosis in lung cancer cells. Mechanistic exploration revealed that NC exhibited its antitumor effects by reducing NEDD4 expression. Furthermore, our rescue experiments dissected that overexpression of NEDD4 abrogated the NC-mediated antineoplastic effects in lung cancer cells. Consistently, downregulation of NEDD4 enhanced the NC-induced anticancer effects. Thus, NC is a promising antitumor agent in lung cancer, indicating that NC might have potential therapeutic applications in the treatment of lung cancer.

Abstract
Nitidine chloride (NC) was recently reported to exhibit a wide range of pharmacological properties for several diseases, including cancer. Here we report for the first time that NC is a potential therapeutic agent for mucoepidermoid carcinoma (MEC) occurring in the head and neck because it suppresses X chromosome-linked inhibitor of apoptosis protein (XIAP) in human MEC in vitro and in vivo. The antitumor effects of NC were evaluated by trypan blue exclusion assay, western blotting, live/dead assay, 4',6-diamidino-2-phenylindole (DAPI) staining, human apoptosis antibody array, immunofluorescence staining, immunohistochemistry, small interfering RNA assay, transient transfection of XIAP overexpression vector, terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay, and histopathological examination of organs. NC inhibited cell viability and induced caspase-dependent apoptosis in vitro. A human apoptosis antibody array assay showed that XIAP is suppressed by NC treatment. XIAP was overexpressed in oral squamous cell carcinoma (OSCC) tissues that arose from the head and neck, and high XIAP expression was correlated with poor prognosis in OSCC patients. XIAP depletion significantly increased apoptosis, and ectopic XIAP overexpression attenuated the apoptosis induced by NC treatment. NC suppressed tumor growth in vivo at a dosage of 5 mg/kg/day. The number of TUNEL-positive cells increased and the protein expression of XIAP was consistently downregulated in NC-treated tumor tissues. In addition, NC caused no histopathological changes in the liver or kidney. These findings provide new insights into the mechanism of action underlying the anticancer effects of NC and demonstrate that NC is a promising therapeutic agent for the treatment of human MEC of the head and neck. KEY MESSAGES: • Nitidine chloride induces caspase-dependent apoptosis in MEC of the head and neck. • High XIAP expression correlates with poor prognosis of OSCC patients. • Nitidine chloride suppresses tumor growth in vivo without any systemic toxicities. • Targeting XIAP is a novel chemotherapeutic strategy for MEC of the head and neck.

Abstract
Nitidine chloride (NC), a quaternary ammonium alkaloid, exhibits multiple biological activities, including antimalarial, antifungal, and antiangiogenesis. Recently, NC has been characterized to perform antitumor activity in a variety of malignancies. NC has been identified to suppress cell proliferation, stimulate apoptosis, and induce cell cycle arrest, retard migration, invasion and metastasis. Moreover, NC is reported to sensitize cancer cells to chemotherapeutic drugs. In this review article, we describe the functions of NC in human cancers and discuss the molecular insight into NC-involved antitumor feature. This review article will stimulate the deeper investigation for using NC as a potent agent for the management of cancer patients.

Abstract
Nitidine chloride (NC) has reported tumor suppressive activities for various human cancers, including hepatocellular carcinoma (HCC). Nevertheless, the pharmacological mechanism of NC on HCC has not previously been elucidated. SMMC7721 HCC cell lines, before and after the treatment of NC, were injected into nude mice for a subcutaneous tumor xenograft model. MiRNA and mRNA sequencing were performed for both control and treated xenograft tissues to further analyze differential expressed miRNAs (DEmiRNAs) and mRNAs (DEmRNAs). The ten most significant DEmiRNAs were selected for prediction of transcription factors (TFs) and target genes. We constructed an interconnected network composed of TFs the ten most significant DEmiRNAs, the 100 most significant DEmRNAs, and selected target genes from online programs. Hub genes chosen from a protein-to-protein interaction network of hub genes were validated by correlation analysis, expression analysis, and Kaplan-Meier survival analysis. The five most up-regulated miRNAs (hsa-miR-628-5p, hsa-miR-767-5p, hsa-miR-767-3p, hsa-miR-1257, and hsa-miR-33b-3p) and the five most down-regulated miRNAs (hsa-miR-378d, hsa-miR-136-5p, hsa-miR-451a, hsa-miR-144-5p, and hsa-miR-378b) were singled out from the DEmiRNAs. Functional annotations indicated that potential target genes of the top five up-regulated miRNAs were mainly clustered in molecular processes concerning epithelial-to-mesenchymal transition. Hub genes, such as ITGA6 and ITGB4, were validated as up-regulated in HCC; both IFIT2 and IFIT3 were revealed by Kaplan-Meier survival curves as good prognostic factors for HCC. In summary, the regulating axes of NC-DEmiRNAs-DEmRNAs and TFs-DEmiRNAs-DEmRNAs in HCC that were discovered in this study may shed light on the possible molecular mechanism of NC in HCC.

Abstract
Psoriasis is a common dermatosis causing considerable inconvenience to 4% of the general population. Traditional psoriasis treatments often cause side effects, drug resistance and complications, necessitating development of safer and more effective treatments. In this study, we screened over 600 natural compounds to identify viability inhibitors of human HaCaT keratinocytes cultured in vitro. The results showed that nitidine chloride was a highly effective inhibitor. Further studies revealed that nitidine chloride inhibited HaCaT proliferation and induced S phase cell cycle arrest; these effects were associated with reduced DNA synthesis, decreased Ki67, cyclin A, and cyclin D1 levels, and increased p53 protein expression. Nitidine chloride also significantly downregulated bcl-2 and upregulated bax, cleaved caspase-9 and cleaved caspase-3. Mechanistic studies revealed that nitidine chloride-induced apoptosis involved the c-Jun N-terminal kinase (JNK) pathway. More importantly, in 12-O-tetradecanoyl-phorbol-13-acetate (TPA)- and imiquimod (IMQ)-induced epidermal hyperplasia and inflammation models, nitidine chloride inhibited topical edema in mouse ear and back skin, substantially reducing tissue thickness and weight. In some cases, nitidine chloride also ameliorated conditions caused by TPA and IMQ, such as angiogenesis and infiltration of large numbers of inflammatory cells around blood vessels. Additionally, nitidine chloride inhibited the expression of various proinflammatory cytokines in the two animal models. In conclusion, our results are the first to demonstrate that nitidine chloride inhibits the proliferation of HaCaT cells, induces apoptosis partly via the JNK signaling pathway in vitro and ameliorates skin lesions and inflammation in vivo, making it an appropriate candidate for psoriasis treatment.

Abstract
The treatment of bovine and equine piroplasmosis is limited to diminazene aceturate (DA) and imidocarb dipropionate. To address this challenge, we need to explore novel drug compounds and targets. Topoisomerases are potential drug targets because they play a vital role in solving topological errors of DNA strands during replication. This study documented the effectiveness of topoisomerase inhibitors, nitidine chloride (NC) and camptothecin (Cpt), on the growth of Babesia and Theileria parasites. The half maximal inhibitory concentrations (IC50s) against B. bovis, B. bigemina, B. caballi, and T. equi were 1.01 ± 0.2, 5.34 ± 1.0, 0.11 ± 0.03, and 2.05 ± 0.4 μM for NC and 11.67 ± 1.6, 4.00 ± 1.0, 2.07 ± 0.6, and 0.33 ± 0.02 μM for Cpt, respectively. The viability experiment revealed that 4, 10, and 4 μM treatments of NC or 48, 8, and 8 μM treatments of Cpt were sufficient to stop the in vitro regrowth of B. bovis, B. bigemina, and B. caballi, respectively. However, T. equi regrew in all of the concentrations used. Moreover, increasing the concentration of NC and Cpt to 16 μM and 1.2 μM (8 × IC50) did not eliminate T. equi. The micrographs of B. bigemina and B. caballi taken at 24 h and 72 h showed deformed merozoites and remnants of parasites within the red blood cell (RBC), respectively. The treatments of 25 mg/kg DA and 20 mg/kg NC administered intraperitoneally and 20 mg/kg NC given orally showed 93.7, 90.7, and 83.6% inhibition against Babesia microti (B. microti), respectively, compared to the untreated group on day 8. In summary, NC and Cpt were effective against Babesia and Theileria parasites in vitro. Moreover, 20 mg/kg NC administered intraperitoneally was as effective as 25 mg/kg DA against B. microti in mice and showed no toxic symptoms in mice. The results indicate that NC may, after further evaluations, prove to be an alternative drug against bovine and equine piroplasmoses.

Abstract
BACKGROUND Nitidine chloride (NC) is known to exert anticancer and anti-metastatic effects on a variety of tumors. Recently, NC has also been shown to inhibit PIK3/AKT/mTOR axis in U87 human glioma cells. METHODS The study shows NC employing pDok2, caspase 3 dependent cell death in C6 rat glioma and U87 human malignant glioblastoma cells. The effect of NC on glioblastoma cell lines was accessed by MTT, clonogenic and wound healing assays. Cell cycle analysis was performed by FACS. Moreover, the effect of NC on downstream target proteins, such as caspase3, pDok2, PARP, and Gsk3 beta, were measured by western blotting. RESULTS Overexpressed pDok2 protein has recently been reported as a prognostic marker with poor outcomes for human glioblastoma multiformae. We found that NC inhibits pDok2 in U87 cells in a concentration-dependent way. We further showed that cleaved PARP and cleaved caspase 3 protein expressions were increased in C6 cells treated with NC in a dose-dependent way. NC effectively attenuated C6 cells growth and colony formation at 8μM (micromoles) concentration. Cell cycle arrest in G2/M phase was further confirmed by flow cytometry. NC also exhibited its inhibitory effect on Gsk3 beta, which has been proven to be altered in glioma biology. CONCLUSIONS Collectively, we predicted that NC could be employed as a potential anti-glioma mediator that needs attention to explore the mechanisms of its activity.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Fagara tessmannii is a shrub of the African rainforests used to treat bacterial infections, cancers, swellings and inflammation. In the present study, the methanol extract from the leaves (FTL), bark (FTB), and roots (FTR) of this plant as well as fractions (FTR1-5) and compounds isolated from FTR namely β-sitosterol-3-O-β-d-glucopyranoside (1), nitidine chloride (2) and buesgenine (3), were tested for their antimicrobial activities against a panel of Gram-negative bacteria including multidrug resistant (MDR) phenotypes. MATERIALS AND METHODS The broth microdilution method was used to determine the minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) of the above samples; Column chromatography was used for the fractionation and purification of the roots extract whilst the chemical structures of compounds were determined using spectroscopic techniques. RESULTS Results of the MIC determinations indicated that the crude extracts from the roots as well as fraction FTRa4 were active on all the 26 tested bacterial strains. MIC values below 100µg/mL were obtained with roots, leaves and bark extract respectively against 30.8%, 15.4% and 11.5% tested bacteria. The lowest MIC value below of 8µg/mL was obtained with extract from the roots against Escherichia coli MC100 strain. The lowest MIC value of 4µg/mL was also obtained with compound 3 against E. coli AG102 and Klebsiella pneumoniae ATCC11296 CONCLUSIONS: The present study demonstrates that F. tessmannii is a potential source of antimicrobial drugs to fight against MDR bacteria. Benzophenanthrine alkaloids 2 and 3 are the main antibacterial consituents of the roots of the plant.

Abstract
Nitidine Chloride (NC) has been shown to have anti-cancer effects on various tumors. However, whether NC could exert anti-metastasis activity in renal cancer cells and the underlying mechanisms have not been elucidated. In this work, our data demonstrated the anti-metastasis effects of NC on renal cancer cells in vitro. With scratch assay and transwell assays, we found that NC potently suppressed the migration and invasion of 786-O and A498 cells. Mechanistically, we presented that NC significantly decreased phosphorylation of AKT, accompanied by down-regulation of MMP-2 and MMP-9. Furthermore, a specific AKT inhibitor, LY294002, could enhance the anti-metastasis effects of NC, which indicated that NC suppressed metastasis of renal cancer cells partly via inhibition of AKT activity. Taken together, our results imply that NC can be developed as a potential anti-metastasis agent to renal cancer.
