Liu Z, Li B, Cao M, Jiang J. Norcantharidin triggers apoptotic cell death in non-small cell lung cancer via a mitophagy-mediated autophagy pathway. ANNALS OF TRANSLATIONAL MEDICINE 2021; 9:971. [PMID: 34277771 PMCID: PMC8267262 DOI: 10.21037/atm-21-2360] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/31/2021] [Accepted: 06/02/2021] [Indexed: 01/29/2023]
Abstract
Background Norcantharidin (NCTD) is known to impact on cell progression in many cancers; however, its activity in non-small cell lung cancer (NSCLC) has not yet been characterized. In the present study, we set out to determine the cytotoxic effects of NCTD on the proliferation and apoptosis on A549 cells and their underlying mechanisms. Methods NSCLC cell line A549 cells were cultured. A549 cells were treated with different concentrations of NCTD. Cell proliferation was detected by MTT and cell clone formation assay. Cell cycle and apoptosis were detected by flow cytometry. After A549 cells were treated with NCTD for 24 hours, the mitochondrial membrane potential was measured. The protein expression of Bcl-2, Bax, light chain 3 (LC3), et al. was tested by western blot. The expression of LC3 and Tom20 protein was detected by immunofluorescence. Results NCTD suppressed the proliferation of NSCLC cells while decreasing mitochondrial membrane potential and inducing G2/M phase arrest. NCTD induced apoptosis, as demonstrated by increased B-cell lymphoma 2/Bcl-2-associated X protein and Bcl-2-associated X protein/myeloid cell leukemia 1 ratios. Aside from autophagy, NCTD induced mitophagy, with an increase in LC3 expression and a decrease in sequestosome 1 (p62) expression in the cytoplasm, accompanied by increased levels of Phospho-adenosine 5'-monophosphate -activated protein kinase (p-AMPK), Phospho-c-Jun NH2-Terminal Kinase (p-JNK), and Phospho-c-jun (p-c-jun) and a decreased level of Phospho-protein kinase B (p-AKT). Conclusions This study has elucidated that NCTD restrains NSCLC cell progression via regulation of AMPK/mammalian target of rapamycin (mTOR)/uncoordinated 51-like kinase 1 (ULK1)/JNK pathways. This evidence provides insight into a novel treatment for NSCLC.

Norcantharidin combined with 2-deoxy-d-glucose suppresses the hepatocellular carcinoma cells proliferation and migration. 3 Biotech 2021; 11:142. [PMID: 33708465 DOI: 10.1007/s13205-021-02688-w] [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: 10/01/2020] [Accepted: 02/12/2021] [Indexed: 10/22/2022] Open
Abstract
Present study aims to investigate the combined effect of anticancer drug, norcantharidin (NCTD) in combination with glycolytic inhibitor, i.e. 2-deoxy-d-glucose (2-DG) in liver cancer (HepG2 and Hepa 1-6) cells. Cell viability of NCTD and 2-DG exposed cells was determined by MTT assay, whereas, colony-forming efficiency and migration rate was determined by clonogenic assay and wound healing assay, respectively. Nuclear DAPI staining and Annexin V FITC-PI staining were used to study the apoptosis induction in cells. Fluorescence microscopy imaging was performed to detect the intracellular reactive oxygen species (ROS) generation and mitochondrial membrane potential by staining with DCFDA and JC-1 dye, respectively. Cell viability assay revealed that NCTD and 2-DG exposure in combination displays more cytotoxic effect than a single drug. Additionally, cells lose their colony formation efficiency, as well as the reduced migration rate ability was also observed upon combined exposure. Increased nuclear condensation and mitochondrial membrane depolarization are considered as key features for apoptosis induction in cancerous cells. Furthermore, oxidative stress produced in cells due to enhanced intracellular ROS generation is also major probability for cellular damage. Thus, from the initial data it can be concluded that further preclinical studies will be needed to prove the efficacy of NCTD and 2-DG in hepatocellular carcinoma therapy.

The Synthesis, Anticancer Activity, Structure-Activity Relationships and Molecular Modelling Studies of Novel Isoindole-1,3(2H)-dione Compounds Containing Different Functional Groups. Anticancer Agents Med Chem 2020; 20:1368-1378. [DOI: 10.2174/1871520620666200410080648] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2019] [Revised: 02/20/2020] [Accepted: 03/02/2020] [Indexed: 11/22/2022]
Abstract
Background:
Isoindole-1,3(2H)-dione derivatives are known to have cytotoxic effects on many
cancer cells. The anticancer activity of these compounds varies depending on the substituents attached to them.
Therefore, the effect of substituents is very important when determining the anticancer activities of molecules.
We have recently reported an example of the substituent effect.
:
According to that work, the anticancer activity against HeLa, C6, and A549 cancer cell lines of isoindole-
1,3(2H)-dione compounds containing tert-butyldiphenylsilyl ether, azido, and hydroxyl groups was examined by
our group. It was found that an isoindole-1,3(2H)-dione compound containing both tert-butyldiphenylsilyl ether
group and azido groups showed higher anticancer activity than 5-fluorouracil and another isoindole-1,3(2H)-
dione compound containing both azido and hydroxyl groups.
:
After we discovered that tert-butyldiphenylsilyl ether group in the skeletal structure of isoindole-1,3(2H)-dione
exhibits anticancer activity against HeLa, C6, and A549 cancer cell lines, we wanted to examine the anticancer
activities of different silyl ether groups, i.e., OTMS, -OTBDPS, and -OTBDMS groups, and also -OH and -Br
groups, by comparing them with each other according to the structure–activity relationship.
Methods:
All of the synthesized compounds were characterized by 1H and 13C NMR spectra, IR spectroscopy,
and mass spectra measurements. The IC50 values of these compounds were calculated for all cancer cell lines
and compared with each other and cisplatin, which is a platinum-containing chemotherapeutic drug. Molecular
modelling studies were carried out using the MOE software package.
Results:
It was found that compounds 13 and 16, containing both silyl ether (-OTBDMS) and -Br groups,
showed higher anticancer activity than cisplatin against both Caco-2 and MCF-7 cell lines. Compounds 20 and
23 showed anticancer activity in MCF-7 cells and compounds 8, 9, 20, and 23 in Caco-2 cells. While
compounds 20 and 23 have only a silyl ether (-OTMS) group, compounds 8 and 9 have only a -OH group.
Molecular modelling studies indicated that compounds 8 and 13, as well as their analogs, may bind to the active
site of hRS6KB1 (pdb: 4l3j), compound 11 may bind to the active site of human mTOR (pdb: 4jt5) and
additionally, compounds 10-17 are expected to be both mutagenic and reactive according to the mutagenicity
and reactivity calculations.
Conclusion:
According to these results, the anticancer activities of isoindole-1,3(2H)-dione compounds (8 - 23)
vary depending on the groups they contain and these groups affect each other's activities. Silyl ethers
(-OTBDMS and -OTMS) and -OH and -Br groups in the skeletal structure of isoindole-1,3(2H)-dione can be
regarded as anticancer agents. In this sense, compounds 13 and 16, containing both silyl ether (-OTBDMS) and -
Br groups, may be regarded as alternative chemotherapeutic drugs. This work may lead to the synthesis of new
isoindole-1,3(2H)-dione compounds containing different silyl ether groups and studies evaluating their
anticancer activities or other biological properties.

Abstract
Novel polymer-drug conjugates (CNC) were prepared from carboxymethyl chitosan (CMCS) and norcantharidin (NCTD) via amidation reaction and characterized by FTIR and 1H NMR spectroscopy. The aim of this study was to elucidate the antitumor efficacy of CNC on gastric cancer and the possible underlying mechanisms. The CNC conjugates possessed significant inhibitory effects on the proliferation of SGC-7901 cells and suppressed the migration as well as tube formation of HUVECs. Besides, Hoechst 33258 staining and Annexin V-FITC/PI detection suggested that the conjugates were more effective in triggering apoptosis of SGC-7901 cells compared with free NCTD. Moreover, CNC remarkably reduced systemic toxicity and enhanced the antitumor efficacy in vivo with a tumor suppression rate of 59.57% against SGC-7901 gastric tumor in BALB/c nude mice. Further investigation about the underlying mechanisms indicated that CNC could upregulate expressions of TNF-α and Bax, and downregulate expressions of VEGF, Bcl-2, MMP-2 and MMP-9, thereby inhibiting tumor metastasis and inducing apoptosis in vivo. Overall, our results demonstrated that CNC might be a promising and feasible polymer therapeutics for gastrointestinal tumor therapy.

Abstract
Cantharidin, a natural toxin from blister beetles, has shown potent anticancer activities on many solid tumor cells. Recently, cantharidin and its analogue, norcantharidin, were also shown to suppress nonsolid tumors such as chronic myeloid leukemia, acute myeloid leukemia (AML), and leukemic stem cells. However, there is no available information to address the effects of cantharidic acid (CAC), a hydrolysis product of cantharidin, on human AML cells. The present study showed that CAC, at a range of concentrations (0-20 μM), concentration-dependently inhibited cell proliferation in the HL-60 AML cell line. Western blot and flow cytometric assays demonstrated that CAC induced several features of apoptosis such as sub G1-phase cell increase, phosphatidylserine (PS) externalization, and significantly activated proapoptotic signaling including caspase-8, -9, and -3 activation and poly(ADP-ribose) polymerase (PARP) cleavage in HL-60 AML cells. Moreover, treatment of HL-60 cells with CAC induced concentration- and time- dependent activation of p38 mitogen-activated protein kinase (p38 MAPK) and c-Jun N-terminal kinase (JNK). Only JNK-, but not p38 MAPK-specific inhibitor can reverse the CAC-induced activation of the caspase-8, -9, and -3. We concluded that CAC can induce apoptosis in human leukemic HL-60 cells via a caspases-dependent pathway, and that the apoptosis-inducing effect of CAC can be regulated by JNK activation signaling.

Abstract
While Nasopharyngeal carcinoma (NPC) is uncommon in western countries, it is endemic in Southeast Asia and Southern China. Previous study of norcantharidin (NCTD), isolated from blister beetles, has proved its anticancer effect on various tumors. However, the effect of NCTD in NPC has never been studied. The purpose of this study is to inspect the suppression activity of NCTD on NPC, along with the underlying mechanism. NPC cell line NPC-BM was treated with NCTD. NCTD remarkably inhibited proliferation and induce apoptosis in NPC-BM cell. Activation of caspase-3, -8, -9 was observed through western blotting. The expression of antiapoptotic protein Bcl-XL was significantly reduced, but expression of proapoptotic protein Bak was increased after treatment of NCTD. The cytotoxic effect of NCTD on NPC-BM cell is mainly due to apoptosis, mediated by caspase and mitochondrial pathway. These results suggested that NCTD could be a potential anticancer agent for NPC.

Abstract
To identify an agent with specific activity against B-lineage leukaemia stem cells (B-LSCs), we generated norcantharidin (NCTD)-encapsulated liposomes modified with a novel humanised anti-human CD19 monoclonal antibody, Hm2E8b (Hm2E8b-NCTD-liposomes). These liposomes were specially designed to recognise and kill B-LSCs in vitro, and to decrease non-specific cytotoxicity to untargeted cells. Hm2E8b-NCTD-liposomes selectively ablated B-LSCs through targeting hepatic leukaemia factor (HLF), which is implicated in haematopoietic stem cell regulation and is overexpressed in LSCs. Hm2E8b-NCTD-liposomes decreased HLF protein levels and induced apoptosis in the HAL-01 cell line harbouring the oncoprotein E2A-HLF. This resulted in modulation of the expression of several molecules that govern survival pathways, including HLF, SLUG, NFIL3 and C-Myc, thereby causing the induction of p53 and the mitochondrial caspase cascade. Therefore, the potent in vitro effect of Hm2E8b-NCTD-liposomes on B-LSC activity and survival pathways have the potential to be exploited clinically with appropriate drug combinations.

Abstract
Norcantharidin (NCTD), a demethylated analog of cantharidin derived from Chinese traditional medicine blister beetle, has been currently used as an anticancer drug for various cancers including hepatocellular carcinoma (HCC). In this study, for a more comprehensive understanding of the targets of NCTD in HCC, next-generation RNA-Seq was utilized. We revealed that the expression of FAM46C, which has been reported as a tumor suppressor for multiple myeloma, was enhanced after NCTD treatment. Re-analysis of TCGA (The Cancer Genome Atlas) LIHC (liver hepatocellular carcinoma) dataset demonstrated that FAM46C expression was significantly lower in HCC tissues than in normal liver tissues. NCTD injection or FAM46C overexpression could mitigate diethylnitrosamine (DEN)-initiated HCC in mice. Ectopic expression of FAM46C in two HCC cell lines, SMCC-7721 and SK-Hep-1, significantly repressed cell proliferation, and increased cells population in G2/M phase and cell apoptotic rate. We also found that FAM46C overexpression caused a notable decrease in Ras expression, MEK1/2 phosphorylation and ERK1/2 phosphorylation. More importantly, FAM46C knockdown significantly weakened the biological effects of NCTD on HCC cells, which suggested NCTD exerted the anticancer functions partially through up-regulating FAM46C. In conclusion, FAM46C, a tumor suppressor for HCC, is important for the anti-proliferation and proapoptotic effects of NCTD.

[PMID: 26755751 PMCID: PMC5616112 DOI: 10.1177/1533034615624583] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2015] [Revised: 11/01/2015] [Accepted: 11/19/2015] [Indexed: 12/21/2022] Open
Abstract
Norcantharidin, a low-toxic analog of the active anticancer compound cantharidin in Mylabris, can inhibit proliferation and induce apoptosis of multiple types of cancer cells. However, the anticancer activities of norcantharidin with respect to neuroblastoma, and its underlying mechanisms, have not been investigated. Therefore, our study was designed to determine the efficacy of norcantharidin on SK-N-SH neuroblastoma cell death and to elucidate detailed mechanisms of activity. In the present study, norcantharidin suppressed the proliferation and cloning ability of SK-N-SH cells in a dose-dependent manner, apparently by reducing the mitochondrial membrane potential and arresting SK-N-SH cells at the G2/M stage, accompanied by elevated expressions of p21 and decreased expressions of cyclin B1 and cell division control 2. Treatment by norcantharidin induced significant mitophagy and autophagy, as demonstrated by a decrease in Translocase Of Outer Mitochondrial Membrane 20 (TOM20), increased beclin1 and LC3-II protein expression, reduced protein SQSTM1/p62 expression, and accumulation of punctate LC3 in the cytoplasm of SK-N-SH cells. In addition, norcantharidin induced apoptosis through regulating the expression of B-cell lymphoma 2-associated X protein/B-cell lymphoma 2 and B-cell lymphoma 2-associated X protein/myeloid cell leukemia 1 and activating caspase-3 and caspase-9-dependent endogenous mitochondrial pathways. We also observed an increase in phosphor-AMP-activated protein kinase accompanied with a decrease in phosphor-protein kinase B and mammalian target of rapamycin expression after treatment with norcantharidin. Subsequent studies indicated that norcantharidin participates in cellular autophagy and apoptosis via activation of the c-Jun NH2-terminal kinases/c-Jun pathway. In conclusion, our results demonstrate that norcantharidin can reduce the mitochondrial membrane potential, induce mitophagy, and subsequently arouse cellular autophagy and apoptosis; the AMP-activated protein kinase, protein kinase B/mammalian target of rapamycin, and c-Jun NH2-terminal kinases/c-Jun signaling pathways are widely involved in these processes. Thus, the traditional Chinese medicine norcantharidin could be a novel therapeutic strategy for treating neuroblastoma.

[PMID: 27351942 DOI: 10.1016/j.pharep.2016.04.010] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/29/2016] [Revised: 04/12/2016] [Accepted: 04/15/2016] [Indexed: 12/21/2022]
Abstract
BACKGROUND Norcantharidin, a modified pure compound from blister beetles, was previously demonstrated to induce apoptosis of cancer cells. This study investigated its anti-cancer activity in prostate cancer cells and the mechanisms involved. METHODS Two human prostate cancer cell lines, 22Rv1 and Du145, were treated with norcantharidin at concentrations ranging from 3 to 30μg/ml. Cytotoxic effect of norcantharidin was determined by use of the 3-(4,5-dimethylthiazol-yl)-diphenyl tetrazoliumbromide (MTT) assay. The effects of apoptosis were evaluated by cell death assay, Caspase-3, -8, -9 activity and cytochrome c release. The apoptotic related protein expressions (Bcl-2 family and inhibitor of apoptosis proteins) were determined using western blotting. RESULTS An MTT assay revealed that norcantharidin induced cytotoxicity against both prostate cancer cells in dose- and time-dependent manners. Treatment with norcantharidin at 3μg/ml or higher significantly increased oligonucleosomal formation with concomitant appearance of PARP cleavage, implicating the induction of apoptosis. Norcantharidin intrinsically elevated cytosolic cytochrome c levels and activated caspase-3, -8, and -9. Extrinsically, it upregulated the expression of not only the death receptors Fas and DR5 in 22Rv1 cells, but also of RIP and TRADD adaptor proteins in Du145 cells. Mechanistically, norcantharidin increased ratios of pro-/anti-apoptotic proteins and decreased expression of IAP family member proteins, including cIAP1 and survivin, regardless of the distinct status of androgen receptor expression in both cells. CONCLUSIONS Norcantharidin exhibited cytotoxicity against 22Rv1 and Du145 prostate cancer cells by inducing both intrinsic and extrinsic apoptotic pathways and could thus potentially be a remedy for prostate cancer.

Norcantharidin inhibits Wnt signal pathway via promoter demethylation of WIF-1 in human non-small cell lung cancer. Med Oncol 2015; 32:145.

Abstract
Wingless-type (Wnt) family of secreted glycoproteins is a group of signal molecules implicated in oncogenesis. Abnormal activation of Wnt signal pathway is associated with a variety of human cancers, including non-small cell lung cancer (NSCLC). Wnt antagonists, such as the secreted frizzled-related protein (SFRP) family, Wnt inhibitory factor-1 (WIF-1) and cerberus, inhibit Wnt signal pathway by directly binding to Wnt molecules. Norcantharidin (NCTD) is known to possess anticancer activity but less nephrotoxicity than cantharidin. In this study, we found that NCTD inhibited cell proliferation, induced apoptosis, arrested cell cycle and suppressed cell invasion/migration in vitro. Additionally, Wnt signal pathway transcription was also suppressed. NCTD treatment blocked cytoplasmic translocation of beta-catenin into the nucleus. Alterations of apoptosis-related proteins, such as Bax, cleaved caspase-3 (pro-apoptotic) and Bcl-2 (anti-apoptotic), had been detected. Furthermore, the expression levels of WIF-1 and SFRP1 were significantly increased in NCTD-treated groups compared with negative control (NC) groups. Abnormal methylation was observed in NC groups, while NCTD treatment promoted WIF-1 demethylation. The present study revealed that NCTD activated WIF-1 via promoter demethylation, inhibiting the canonical Wnt signal pathway in NSCLC, which may present a new therapeutic target in vivo.

Abstract
This study aimed to evaluate the effects of cantharidins, a traditional Chinese medicine, in chemotherapy for the treatment of hepatoma. From August 2011 to December 2012, 96 patients with hepatoma, who were eligible for transcatheter hepatic arterial chemoembolization and received cantharidins, were selected for comparison with the control group of 95 patients without cantharidins. The treatment effect, clinical symptoms and adverse effects were analyzed. The results of the study showed that the cantharidins group had a higher overall efficient rate than the control group (p < 0.001). The improvement rate of the Karnofsky score in the cantharidins group was significantly higher than that of the control group (p = 0.014). In the cantharidins group, there was a decrease in white blood cell (WBC) count and gastrointestinal response rates were lower than those of the control group (p < 0.05). Therefore, the traditional Chinese medicine cantharidins showed effects of easing the progress of liver cancer, relieving side effects of chemotherapy and improving the quality of life in the treatment of hepatoma.

Abstract
This research attempted to study the effect of lipophilicity on the anticancer activity of N-substituted norcantharimide derivatives. Twenty-three compounds were synthesized and their cytotoxicities against five human cancer cell lines studied. The lipophilicity of each derivative was altered by its substituent, an alkyl, alkyloxy, terpenyl or terpenyloxy group at the N-position of norcantharimide. Further, among all synthesized derivatives studied, the compounds N-farnesyloxy-7-oxabicyclo[2.2.1]heptane-2,3-dicarboximide (9), and N-farnesyl-7-oxabicyclo[2.2.1]heptane-2,3-dicarboximide (18), have shown the highest cytotoxicity, anti-proliferative and apoptotic effect against human liver carcinoma HepG2 cell lines, yet displayed no significant cytotoxic effect on normal murine embryonic liver BNL CL.2 cells. Their overall performance led us to believe that these two compounds might be potential candidates for anticancer drugs development.

Abstract
Norcantharidin (NCTD), a demethylated analog of cantharidin derived from blister beetles, has attracted considerable attentions in recent years due to their definitely toxic properties and the noteworthy advantages in stimulating bone marrow and increasing the peripheral leukocytes. Hence, it is worth studying the anti-tumor effect of NCTD on human prostate cancer cells DU145. It was found that after the treatment of NCTD with different concentrations (25-100 μM), the cell proliferation was significantly inhibited, which led to the appearance of micronucleus (MN). Moreover, the cells could be killed in a dose-/ time-dependent manner along with the reduction of PCNA (proliferating cell nuclear antigen) expression, destruction of mitochondrial membrane potential (MMP), down-regulation of MnSOD, induction of ROS, depletion of ATP, and activation of AMPK (Adenosine 5‘-monophosphate -activated protein kinase) . In addition, a remarkable release of cytochrome c was found in the cells exposed to 100 μM NCTD and exogenous SOD-PEG could eliminate the generation of NCTD-induced MN. In conclusion, our studies indicated that NCTD could induce the collapse of MMP and mitochondria dysfunction. Accumulation of intercellular ROS could eventually switch on the apoptotic pathway by causing DNA damage and depleting ATP.

Abstract
Norcantharidin (NCTD) is currently used for anticancer therapy but the exact mechanism of action remains unknown. Pre-replicative complexes (pre-RCs) are essential for cell DNA replication and highly related to malignant proliferation. Here, we examined the inhibitory effect of NCTD on pre-RC components in HepG2 cells. We showed that NCTD induced degradation of Cdc6 and Mcm2 in a dose-dependent manner. Under 100 μM NCTD concentration, about 70% of Cdc6 and 50% of Mcm2 were degraded. In addition, the nuclear translocation of Mcm6 was inhibited by NCTD. Further studies aiming at G1 synchronous cells showed that, NCTD reduced the chromatin-bound Cdc6, Mcm2 and Mcm6. Moreover, the cells were blocked from entering the S phase and accumulated at the G1 phase when released synchronously into the cell cycle. Consistently, the DNA replication was inhibited by NCTD. Finally, the combination NCTD with Cdc6 depletion lead to more severe cytotoxicity (88%) than NCTD (52%) and Cdc6 depletion (39%) alone. A synergic cytotoxicity was observed between Cdc6 depletion and NCTD. In conclusion, our results demonstrate that NCTD inhibits pre-RC assembly; subsequently blocks the G1 to S transition; and inhibits DNA replication in HepG2 cells. Pre-RCs are an intriguing target for cancer therapy, which merits further investigations for anticancer development.

EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2013; 2013:461487.

Abstract
This study aimed to elucidate the antitumor activity of norcantharidin (NCTD) against human mantle cell lymphoma (MCL). Cell proliferation and apoptosis were examined by MTS and flow cytometry. Caspase-3, -8, and -9 activities were detected with a colorimetric caspase protease assay. Apoptotic proteins—including PARP, cyclin D1, Bcl-2 family proteins, XIAP, and cIAP I—were studied by western blot. The phosphoinositide 3 kinase (PI3K) inhibitor LY294002 was used to investigate the involvement of the PI3K/Akt signaling pathway. In vivo studies were performed using Z138 cell xenografts in nude mice. NCTD inhibited proliferation and induced apoptosis of Z138 and Mino cells, both in vitro and in vivo. PI3Kp110α and p-Akt expressions were downregulated by NCTD treatment. NCTD downregulated NF-κB activity by preventing NF-κB phosphorylation and nuclear translocation. This effect was correlated with the suppression of NF-κB-regulated gene products, such as cyclin D1, BAX, survivin, Bcl-2, XIAP, and cIAP. This phenomenon was blocked by the PI3K inhibitor LY294002. Our results demonstrated that NCTD can induce growth arrest and apoptosis in MCL cells and that the mechanism may involve the PI3K/Akt/NF-κB signaling pathway. NCTD may have therapeutic and/or adjuvant therapeutic applications in the treatment of MCL.

Abstract
Norcantharidin is the demethylated analog of cantharidin isolated from blister beetles (Mylabris phalerata Pall.). In this study, we evaluated whether norcantharidin exhibits anticancer effects against the human non-small cell lung cancer cell lines A549 (epidermal growth factor receptor (EGFR) mutation-negative) and PC9 (EGFR mutation-positive). Our results revealed that norcantharidin dose-dependently retards cell growth, arrests cell cycle at G2/M phase, reduces cell migration, and even induces apoptosis at the concentration of 100 µM. Moreover, we found that norcantharidin enhances the anticancer effects of gefitinib and cisplatin. Norcantharidin exhibited similar potency of anticancer effects against the two cell lines with different EGFR mutation status and did not affect EGF-induced EGFR phosphorylation, suggesting that the EGFR signaling may not be the target of norcantharidin. In conclusion, our results suggest that norcantharidin exhibits anticancer effects against non-small cell lung cancer cells in vitro and support its potential as a chemotherapeutic agent for treating non-small cell lung cancer.

Abstract
Norcantharidin (NCTD), a chemically modified form of cantharidin, is a potential anticancer drug. In this study, the effects of NCTD on the cellular viability, reactive oxygen species (ROS), mitochondrial membrane potential (MMP), and DNA damage in the human breast cancer cell line Bcap-37 were investigated with confocal and fluorescence microscopy. The cell cycle was further analyzed using the CellQuest software of a Becton-Dickinson FACS flow cytometer. The results indicated that the cellular viability was decreased with the growing concentrations of NCTD and time exposure. Moreover, the fluorescence intensity of ROS was increased, whereas the MMP was decreased in Bcap-37 cells with the growing concentrations of NCTD. NCTD induced a dose-dependent DNA damage and reduced the G1 peak in Bcap-37 cells. The G2/M peak of Bcap-37 was also decreased by the higher concentration of NCTD.

Abstract
Norcantharidin (NCTD) is the demethylated form of cantharidin, which is the active substance of mylabris, and is known to have anticancer potentials. The aim of this paper was to assess the apoptosis-inducing effect of NCTD on HL-60 cells. Methods. The effects of NCTD were detected by flow cytometer on the cell toxicity, cell cycle, and apoptosis of HL-60 cells cultured in vitro. Results. After 48-hour treatment with NCTD, the growth of HL-60 cells was inhibited significantly. The summit of apoptosis appeared after 24 hours. The percentage of the cells in G1 phase decreased and then increased in S and G2+ M phase, while the S and G2+ M phases were blocked after treatment with 5, 10, and 50 μmol/L NCTD for 24 hours. Conclusions. NCTD can induce the apoptosis of HL-60 cells and inhibit the fissiparism, and the domino effect was obviously correlated with the time and dosage.

Abstract
Multi-drug resistance (MDR), an unfavorable factor compromising treatment efficacy of anticancer drugs, involves upregulated ATP binding cassette (ABC) transporters and activated Sonic hedgehog (Shh) signaling. By preparing human breast cancer MCF-7 cells resistant to doxorubicin (DOX), we examined the effect and mechanism of norcantharidin (NCTD), a small-molecule synthetic compound, on reversing multidrug resistance. The DOX-prepared MCF-7R cells also possessed resistance to vinorelbine, characteristic of MDR. At suboptimal concentration, NCTD significantly inhibited the viability of DOX-sensitive (MCF-7S) and DOX-resistant (MCF-7R) cells and reversed the resistance to DOX and vinorelbine. NCTD increased the intracellular accumulation of DOX in MCF-7R cells and suppressed the upregulated the mdr-1 mRNA, P-gp and BCRP protein expression, but not the MRP-1. The role of P-gp was strengthened by partial reversal of the DOX and vinorelbine resistance by cyclosporine A. NCTD treatment suppressed the upregulation of Shh expression and nuclear translocation of Gli-1, a hallmark of Shh signaling activation in the resistant clone. Furthermore, the Shh ligand upregulated the expression of P-gp and attenuated the growth inhibitory effect of NCTD. The knockdown of mdr-1 mRNA had not altered the expression of Shh and Smoothened in both MCF-7S and MCF-7R cells. This indicates that the role of Shh signaling in MDR might be upstream to mdr-1/P-gp, and similar effect was shown in breast cancer MDA-MB-231 and BT-474 cells. This study demonstrated that NCTD may overcome multidrug resistance through inhibiting Shh signaling and expression of its downstream mdr-1/P-gp expression in human breast cancer cells.

Abstract
INTRODUCTION Norcantharidin (7-oxabicyclo [2.2.1] heptane-2,3-dicarboxylic anhydride) is the demethylated form of cantharidin. Norcantharidin not only has strong anticancer activity, but also eliminates most side-effects in the urinary system, does not cause myelosuppression and increases the number of white blood cells. With structural modification, norcantharidin analogues show potential anticancer activities. AREAS COVERED A comprehensive patent review of norcantharidin analogues from 2006 to 2010 is presented. Protein phosphatase 1, 2A, 2B and 5 inhibitors are described. The review summarizes the new compounds and lays the foundation for seeking more effective anticancer compounds. EXPERT OPINION Although norcantharidin has improved activity and toxicity, the effects routinely do not satisfy the current clinical need. Exploring better analogues is vital for changing the current situation, but norcantharidin is a good lead compound.

Abstract
Antibody-targeting therapy has drawn great interests to the hematologists and oncologists. Many antibodies have been studied for their potential targeting for hematopoietic malignancies. A few have been proved to be very effective for patients with these diseases. However, more antibodies are needed for clinical use. CD45 and its isoforms may convey clinical potential in terms of targeting therapy. Zhejiang Children's Hospital (ZCH)-6-3A4 (3A4), a novel antibody that can recognize an isoform of CD45 has been found to react with restricted cell components in hematopoietic system, which may have the potential for targeting therapy. Herein, we conducted an in vitro study of our newly prepared antibody 3A4 using various cellular and immunocytological methods. The results showed that the antibody 3A4 (murine IgG1κ) was a new clone of anti-CD45RA. It could block the binding to an epitope of CD45RA recognized by a standard anti-CD45RA antibody (Clone name L48). The reactivity of the 3A4 to both fresh leukemia cells from patients and well-defined leukemia cell lines was largely similar to those of L48, but the former recognized more leukemia cells than the latter. Cytometric analysis after papain treatment showed that the internalization rate of the 3A4 antibody to the target cells was as high as 71.3% after incubation at 37°C for 4 h, which was significantly higher than that of L48 (20.4%). The norcantharidin (NCTD)-conjugated immunotoxin (NCTD-3A4) was generated using an active ester method. The targeting inhibition rate on KG1a was as high as 61.10% after 96 h incubation in a dose-dependent manner, which was significantly higher than that (3.56%, P < 0.01) with 3A4-negative Nalm-6 cells. In conclusion, our new anti-CD45RA antibody 3A4 is probably a new target molecule of leukemia cells and holds a targeting therapeutic potential for hematopoietic malignancies, which warrants further development of this agent.

Abstract
Refractory and relapsed leukemia is a major problem during cancer therapy, which is due to the aberrant activation of Wnt/β-catenin signaling pathway. Activation of this pathway is promoted by wingless (Wnt) proteins and induces co-activator β-catenin binding to lymphoid enhancer factor (LEF)/T-cell factor protein (TCF). To provide a convenient system for the screening of anti-Wnt/β-catenin agents, we designed a bi-functional pGL4-TOP reporter plasmid that contained 3X β-catenin/LEF/TCF binding sites and a selectable marker. After transfection and hygromycin B selection, HEK 293-TOP and Jurkat-TOP stable clones were established. The luciferase activity in the stable clone was enhanced by the recombinant Wnt-3A (rWnt-3A; 100-400 ng/mL) and GSK3β inhibitor (2'Z,3'E)-6-bromoindirubin-3'-oxime (BIO; 5 µM) but was inhibited by aspirin (5 mM). Using this reporter model, we found that norcantharidin (NCTD; 100 µM) reduced 80% of rWnt-3A-induced luciferase activity. Furthermore, 50 µM NCTD inhibited 38% of BIO-induced luciferase activity in Jurkat-TOP stable cells. Employing ³H-thymidine uptake assay and Western blot analysis, we confirmed that NCTD (50 µM) significantly inhibited proliferation of Jurkat cells by 64%, which are the dominant β-catenin signaling cells and decreased β-catenin protein in a concentration-dependent manner. Thus, we established a stable HEK 293-TOP clone and successfully used it to identify the Wnt/β-catenin signaling inhibitor NCTD.

Abstract
The effects of norcantharidin (NCTD), an anticancer drug in China, on the growth and migration in human lung cancer cells were investigated by in vitro and ex vivo assays. NCTD significantly inhibited the in vitro and ex vivo growth of human non-small cell lung cancer A549 cells in dose- and time-dependent manners. Western blot analysis indicated that NCTD dose-dependently down-regulated the expression of anti-apoptotic protein Bcl-2 and up-regulated the level of pro-apoptotic protein Bax, eventually leading the reduction of ratio of Bcl-2/Bax proteins in A549 cells. Moreover, NCTD significantly suppressed the A549 cell migration in the case of without reducing the cell viability. More importantly, NCTD significantly enhanced the anticancer activity of anticancer agents such as trichostatin A (the histone deacetylase inhibitor), celecoxib (the inhibitor of cyclooxygenase-2) and lovastatin (the inhibitor of HMG-CoA reductase) by strongly reducing the viability and/or the ratio of Bcl-2/Bax protein in A549 cells. Our findings suggest that NCTD may have the wide therapeutic and/or adjuvant therapeutic application in the treatment of human lung cancer.

Abstract
AIMS This study examined the in vitro and in vivo angiogenic effects of norcantharidin (NCTD), a synthetic, small-molecule antitumor compound. MAIN METHODS Syngeneic colorectal adenocarcinoma CT26 cells were implanted in mice to examine the effect of NCTD on VEGF production and renal and hepatic toxicity. Human umbilical endothelial cells (HUVECs) were used to examine the in vitro effect of NCTD on viability, chemotaxis, vascular network tube formation, adhesive ability, anoikis, and mitogen-activated protein kinase (MAPK) signaling. A protein array was used for analysis of angiogenic factors released from NCTD-treated HUVECs. KEY FINDINGS NCTD suppressed plasma VEGF levels of tumor-bearing mice, without renal or hepatic toxicity. In vitro, NCTD inhibited viability of normal HUVECs to a lesser extent than CT26 cancer cells. At concentrations less than those inhibiting 50% of the cells, NCTD inhibited migration and capillary-like tube formation of HUVECs. The anti-angiogenic effect of NCTD was accompanied by anoikis, down-regulation of integrin beta1, and breakdown of vimentin. NCTD decreased MAPK expression of phosphorylated (p)-JNK and p-ERK. P-P38 expression or P38 inhibitor SB203580 did not impair the effect of NCTD on viability or adhesion of HUVECs. In addition, NCTD inhibited the release of pro-angiogenic factors from HUVECs, but not from CT26 cells. SIGNIFICANCE NCTD is a synthetic, small-molecule compound possessing anti-angiogenetic activity with potential use in anti-cancer therapy as an anti-metastatic and anti-angiogenic agent.

Abstract
The effects of norcantharidin (NCTD) on the growth of highly-metastatic human breast cancer cells were investigated by in vitro and ex vivo assays. Our results indicated that norcantharidin inhibited the in vitro growth of human breast cancer MDA-MB-231 cell line in dose- and time-dependent manners after the cancer cells were treated with norcantharidin at the concentrations of 6, 30 and 60 mumol/L for 24, 48 and 72 h. Moreover, the sera from the NCTD-treated rabbits after intravenous injection of NCTD at 15 and 30 min significantly suppressed the growth of the cancer cells ex vivo. The analyses by Hoechst 33258 staining and flow cytometry showed that the typical apoptotic morphological changes appeared and cell cycles arrested at G2/M phase in MDA-MB-231 cells after the cells were treated for 48 h with NCTD. In addition, NCTD down-regulated the expressions of anti-apoptotic protein Bcl-2 and up-regulated the expressions of pro-apoptotic protein Bax, eventually leading to the reduction of Bcl-2/Bax ratio in MDA-MB-231 cells. Furthermore, NCTD at concentrations of 6, 30 and 60 mumol/L dose-dependently reduced the phosphorylation of Akt and NF-kappaB expression in the breast cancer cell line. Induction of apoptosis and cell cycle arrest as well as reduction of Bcl-2/Bax ratio by NCTD may be the important mechanisms of action of NCTD suppressing the growth of MDA-MB-231 cells, which are associated with inhibition of the Akt and NF-kappaB signaling. Our findings suggest that norcantharidin may have a wide therapeutic and/or adjuvant therapeutic application in the treatment of human breast cancer.

Abstract
Dried Coptidis Rizoma was extracted with boiling water. Conditioned medium was prepared by stimulating human peripheral blood mononuclear cells with Coptidis Rizoma extract (CR). The conditioned medium was then added to human leukemic U937 cells suspension for investigating the antiproliferation effect and the induction of apoptosis. Apparent DNA fragmentation and morphological changes occurred in U937 cells after incubating for 48 h to 72 h with the conditioned medium that had been prepared with 400 microg CR solids/mL. Flow cytometric analysis revealed that the percentage of apoptotic U937 cells increased in a time- and concentration-dependent manner. The upregulation of Bax expression, the downregulation of Bcl-2 and procaspase-3 expression, and the release of cytochrome c from the mitochondria in U937 cells were all observed. Reverse transcription-polymerase chain reaction detected cytokine-related mRNA expressions in human mononuclear cells incubated with CR. An increase in the concentration of CR in culturing medium downregulated granulocyte macrophage colony-stimulatory factor mRNA expression while upregulated interleuken-2 mRNA expression. All the above-mentioned evidences suggest that CR induces the apoptosis of human leukemic U937 cells via the changes in cytokine profile and protein expressions in mitochondria pathway and that CR has the potential to be used in the therapy of leukemia due to its strong apoptosis-promoting effect.

Abstract
AIMS To evaluate potential agents of therapeutic value in tissue inflammation, we studied norcantharidin (NCTD) and its derivatives for their effects on immune responses of human peripheral blood mononuclear cells (PBMC) in vitro. MAIN METHODS PBMC proliferation was evaluated by tritiated thymidine uptake method. The production and gene expression of cytokines were determined with enzyme immunoassays (EIA) and reverse transcription-polymerase chain reaction (RT-PCR), respectively. KEY FINDINGS Five derivatives from NCTD had no significant effect on cell proliferation in PBMC. NCTD inhibited PBMC proliferation induced by phytohemagglutinin (PHA) with a 50% inhibitory concentration (IC(50)) 42.1+/-2.3 microM. The inhibitory action of NCTD did not involve direct cytotoxicity. To localize the point in the PBMC proliferation where arrest occurred, a set of key regulatory events leading to the cell proliferation, including cell cycle progression, production and gene expression of interleukin-2 (IL-2), IL-4, IL-10, and interferon-gamma (IFN-gamma) and cyclins was examined. Data demonstrated NCTD arrested the cell cycle progression of activated PBMC from the G1 transition to the S phase. The cyclin D3, E, A, and B transcripts and protein production in PHA-treated PBMC was reduced by NCTD. Whereas NCTD exerted no effect on IL-4 and IFN-gamma production, it significantly alleviated the production and mRNA expression of IL-2 and IL-10 in activated PBMC. SIGNIFICANCE The suppressant effects of NCTD on proliferation of PBMC activated by PHA therefore appear to be mediated, at least in part, through inhibition of cyclins and IL-2 production and arrest of cell cycle progression in the cells.
