Abstract
Purpose: This study aims to investigate the potential of Oregon grape root extracts to modulate the activity of P-glycoprotein. Methods: We performed 3H-CsA or 3H-digoxin transport experiments in the absence or presence of two sources of Oregon grape root extracts (E1 and E2), berberine or berbamine in Caco-2 and MDCKII-MDR1 cells. In addition, real time quantitative polymerase chain reaction (RT-PCR) was performed in Caco-2 and LS-180 cells to investigate the mechanism of modulating P-glycoprotein. Results: Our results showed that in Caco-2 cells, Oregon grape root extracts (E1 and E2) (0.1-1 mg/mL) inhibited the efflux of CsA and digoxin in a dose-dependent manner. However, 0.05 mg/mL E1 significantly increased the absorption of digoxin. Ten µM berberine and 30 µM berbamine significantly reduced the efflux of CsA, while no measurable effect of berberine was observed with digoxin. In the MDCKII-MDR1 cells, 10 µM berberine and 30 µM berbamine inhibited the efflux of CsA and digoxin. Lastly, in real time RT-PCR study, Oregon grape root extract (0.1 mg/mL) up-regulated mRNA levels of human MDR1 in Caco-2 and LS-180 cells at 24 h. Conclusion: Our study showed that Oregon grape root extracts modulated P-glycoprotein, thereby may affect the bioavailability of drugs that are substrates of P-glycoprotein.

Abstract
Ulcerative colitis (UC) with continuous and extensive inflammation is limited to the colon mucosa and can lead to abdominal pain, diarrhea, and rectal bleeding. Conventional therapies are associated with several limitations, such as systemic side effects, drug degradation, inactivation, and limited drug uptake, leading to poor bioavailability. These restrictions necessitate drug delivery to the colon so that the drug passes through the stomach unchanged and has selective access to the colon. The present study aimed to formulate 5-aminosalicylic acid (5-ASA) and berberine (BBR) in chitosan nanoparticles cross-linked by HPMCP (hydroxypropyl methylcellulose phthalate) as a colon drug delivery system for UC. Spherical nanoparticles were prepared. They showed appropriate drug release in the simulated intestinal fluid (SIF), while the release did not occur in the simulated gastric fluid (SGF). They improved disease activity parameters (DAI) and ulcer index, increased the length of the colon, and decreased the wet weight of the colon. Furthermore, histopathological colon studies showed an improved therapeutic effect of 5-ASA/HPMCP/CSNPs and BBR/HPMCP/CSNPs. In conclusion, although 5-ASA/HPMCP/CSNPs showed the best effect in the treatment of UC, BBR/HPMCP/CSNPs, and 5-ASA/BBR/HPMCP/CSNPs were also effective in vivo study, and this study anticipated they could be helpful in future clinical applications for the management of UC.

Abstract
Equine herpesvirus type 1 (EHV-1) poses a global threat to equines. The anticancer agent berbamine (BBM), a bioactive alkaloid, has been shown to inhibit viral infection. However, whether BBM can inhibit EHV-1 infection remains unclear. This study investigated the effect of BBM treatment on EHV-1 infection. Quantitative PCR (qPCR), immunoblotting, the Reed-Muench method, and pathological examination were employed to study the ability of BBM to inhibit EHV-1 infection, viral DNA replication, viral protein production, virion secretion, and cytopathogenesis in vitro and in vivo. The in vitro studies revealed that 10 μM BBM effectively suppressed EHV-1 viral entry into cells, viral DNA replication, and virion secretion, while the in vivo studies verified the ability of BBM to suppress EHV-1-induced damage of brain and lung tissues and animal mortality. These findings strongly suggest that BBM could be a serious contender in the therapeutic control of EHV-1 infection of equines.

Abstract
Sorafenib (SORA), a multi kinase inhibitor, is the standard first-line targeted therapy approved by the Food and Drug Administration for advanced hepatocellular carcinoma (HCC). However, emerging evidence from clinical practice indicates that SORA alone has only moderate antitumor effects and could not completely inhibit the progression of the disease. Therefore, it is very necessary and urgent to develop novel combination therapy to improve the clinical outcomes of SORA. The pharmacological study on the chemosensitizing effects of natural products has become a hotspot in recent years, which is commonly thought to be a potential way to improve the effectiveness of drugs in clinical use. Berbamine (BBM) has potential sensitizing effects in multiple chemotherapies and target therapy. However, it remains unclarified whether the combination of BBM and SORA as a treatment could exert a synergistic effect on HCC cell lines. In this study, we first investigated whether BBM can increase the sensitivity of HCC cell lines to SORA. The results revealed that the combination of BBM and SORA could synergistically inhibit the growth of two HCC cell lines and promoted their apoptosis. Mechanistically, our results showed that BBM exerted a dose-dependent inhibitory effect on the basal and IL-6-induced STAT3 activation of HCC cell lines. In addition, the combined treatment of BBM and SORA synergistically suppressed STAT3 phosphorylation at Tyr705 and knockdown of STAT3 abolished the sensitization effect of BBM, indicating that BBM's sensitization effect is mainly mediated by its inhibition of STAT3. These findings identify a new type of natural STAT3 inhibitor and provide a novel approach to the enhancement of SORA efficacy by blocking the activation of STAT3.

Abstract
BACKGROUND Cyclea peltata is one of the herbs mentioned in ancient scriptures of Ayurveda and is used in different types of Ayurvedic gritham preparations. Moreover, in traditional/tribal medicine C. peltata is used as digestive, anti-inflammatory, diuretic and to treat jaundice, digestive disorders, etc. OBJECTIVE: Activity guided fractionation of C. peltata and in correlation with the levels of bioactive compound tetrandrine. MATERIALS AND METHODS Preliminary phytochemical screening, estimation of total alkaloid content, preparation of different extracts of C. peltata (crude extract CP, hexane extract HCP, chloroform extract CCP, methanol extract MCP, alkaloid fraction ACP). In vitro anti-inflammatory studies using RAW 264.7 cells and in vitro antioxidant assays of the different extracts of C. peltata. HPTLC estimation of tetrandrine (TET) was carried out using solvent system toluene: ethyl acetate: diethylamine (7.2: 2: 0.8) and isolation of TET from ACP. RESULTS Preliminary phytochemical studies of C. peltata showed the presence of alkaloid content in all extracts. Whereas, saponins, steroids and terpenoids were detected in CP and CCP. ACP and TET showed significant in vitro anti-inflammatory and antioxidant activity when compared to other extracts. ACP and TET (100 μg/ml) treatment significantly inhibited the mRNA expression of iNOS, COX-2, TNF-α in LPS treated RAW 264.7 cells. HPTLC estimation of bioactive compound tetrandrine was highest in ACP-228.4 μg/mg followed by CP-29.62 μg/mg, CCP-23.46 μg/mg, MCP-18.82 μg/mg and HCP-1.25 μg/mg. TET has been isolated from ACP. CONCLUSION The results of the present in vitro assays revealed that the alkaloid fraction (ACP) is the most active fraction when compared to other extracts and has a positive correlation with the levels of bioactive compound tetrandrine.

Abstract
INTRODUCTION Post-trabeculectomy scarring due to excessive proliferation of human Tenon's fibroblasts (HTFs) often led to operation failure. Developing a new anti-fibrosis drug with high efficacy to inhibit HTF cell growth will greatly improve the effectiveness of trabeculectomy. OBJECTIVE This study aims to investigate the effect of berbamine (BBM) treatment on the cell growth and survival of HTFs. METHODS Cultured human fetal Tenon's fibroblasts (HFTFs) were treated with or without different concentrations of BBM. Cell morphology was observed with a phase contrast microscope. A CCK-8 method and Ki67 immunofluorescence were used to determine cell viability and cell proliferation. A scratch test was used to study cell migration. Flow cytometry and TUNEL staining were performed to detect cell apoptosis. The expression of BAX/BCL-2, ERK, and AKT/mTOR pathway components was determined by Western blotting. RESULTS BBM treatment disrupted HFTF normal morphology and inhibited its cell growth in a dose-dependent manner. Ki67 immunofluorescence and scratch assay showed BBM suppressed HFTF cell proliferation and migration. Importantly, BBM dose-dependently increased the BAX/BCL-2 ratio and induced apoptosis in HFTF cells. Western blotting showed BBM significantly inhibited the ERK and AKT/mTOR pathway, and PTEN inhibition ameliorated the inhibitory effect of BBM on cell viability and survival in HFTFs. CONCLUSIONS BBM potently inhibits the cell growth and survival of HTFs through AKT/mTOR and has the potential to serve as an anti-fibrosis drug after trabeculectomy.

Abstract
Background Small molecular inhibitors such as gefitinib (Gefi), which target EGF receptor (EGFR), are considered to be a viable pathway for the selective inhibition of pancreatic cancer (PC) development. However, the large difference in Gefi response between PC patient individuals and PC cell lines severely limits the clinical efficacy of Gefi. Berbamine (BBM) is a well-known natural-derived antitumor agent. However, no study yet exists on whether BBM can enhance the sensitivity of PC cells to Gefi or its underlying mechanisms. Methods MTS assay and clonogenic assay were used to determine whether BBM could enhance the anti-PC activity of Gefi by. Flow cytometric analysis was performed to study the cell cycle progression and rate of apoptosis after combined treatment with BBM and Gefi. Surface plasmon resonance (SPR) and Western blot experiments were carried out to detect the STAT3 binding affinity and the STAT3 inhibitory effect of BBM. Molecular docking and Molecular dynamic simulation were used to predicting the dominant interaction between BBM and STAT3. Results This study found that BBM synergizes with Gefi to inhibit cell growth and induce cell cycle arrest and PC cell apoptosis. Mechanistically, our results showed that BBM and Gefi have synergistic inhibitory effects on STAT3 phosphorylation, but have little effect on other EGFR downstream pathways, suggesting that BBM may exert sensitization through the inhibition of STAT3. Besides, BBM has a high affinity for STAT3 and a good inhibitory effect on STAT3 activation, further indicating that BBM was a potent direct STAT3 inhibitor. Molecular modeling between STAT3 and BBM suggested that BBM formed several key hydrophilic interactions with STAT3. Conclusion Our findings suggest that the combination of BBM and Gefi could be further developed as a potential PC therapy.

Abstract
Berberis vulgaris is a well-known herb in Iran that is widely used as a medicinal plant and a food additive. The aim of this study was to investigate the anti-inflammatory and immunomodulatory effects of Barberry and its main compounds. This narrative review was conducted by searching keywords such as B. vulgaris, Barberry, immunomodulatory, anti-inflammatory, medicinal herbs, plants, and extract, separately or combined in various databases, such as Web of Sciences, PubMed, and Scopus. According to the inclusion and exclusion criteria, just English language articles, which reported effective whole plants or herbal compounds, were included. 21 articles were reviewed in this study. In the in vivo models (mice, rats, and human cells) and in the in vitro models (some organ cells such as the spleen, kidney, blood, and brain), B. vulgaris and its main components showed anti-inflammatory effects in both models. The main mechanisms were the shift of cell immune response to Th2, T reg induction, inhibition of inflammatory cytokines (IL-1, TNF, and IFN-γ), and stimulation of IL-4 and IL-10. The induction of apoptosis in APCs and other effector cells was another important mechanism.

Abstract
The introduction of new crops and the development of the use of wild plants creates the potential to diversify global food production and better enable local adaptation to the diverse and changing environments that humans inhabit. Barberry is widely distributed worldwide and is recognized as a valuable plant. In this review, we summarize the functional compounds and nutraceutical features of barberry species. Barberry plants have fruits, flowers, leaves, stems and roots. All of these parts contain very important compounds, such as anthocyanins, alkaloids, flavonoids, phenolic compounds, vitamins and minerals, etc., which have been used for many years in traditional medicine. These compounds have a strong impact on human health and can be used as a painkiller, as well as for the relief of fever, diarrhea and vomiting. They are also useful for curing liver and vascular problems and preventing many diseases. One of the most important functional compounds in the barberry plant is berberine, which exists in its different parts. Studies have shown that berberine in barberry reduces cholesterol and blood glucose. It can help to prevent Alzheimer's and neoplastic diseases. Furthermore, it has antimicrobial, antifungal and antioxidant properties. According to the investigations, barberry plant derivations can be considered as useful additives and functional compounds in various industries, especially in the food industry. © 2019 Society of Chemical Industry.

Abstract
Tetrandrine is a broadly used bisbenzylisoquinoline alkaloid component of traditional Chinese medicine that has antitumor effects in some cancer types. In this study, we investigated the effects of tetrandrine on leukemia in vitro and in vivo. The results showed that tetrandrine effectively induced differentiation and autophagy in leukemia cells. In addition, tetrandrine treatment activated the accumulation of reactive oxygen species (ROS) and inhibited c-MYC protein expression. Further, we found that treatment with the ROS scavengers N-acetyl-L-cysteine (NAC) and Tiron as well as overexpression of c-MYC reduced tetrandrine-induced autophagy and differentiation. Moreover, a small molecular c-MYC inhibitor, 10058-F4, enhanced the tetrandrine-induced differentiation of leukemia cells. These results suggest that ROS generation and c-MYC suppression play important roles in tetrandrine-induced autophagy and differentiation, and the results from in vivo experiments were consistent with those from in vitro studies. Therefore, our data suggest that tetrandrine may be a promising agent for the treatment of leukemia.

Abstract
Multiple myeloma (MM) remains incurable despite the development and the use of new agents. In our studies, we found that 4-chlorbenzoyl berbamine (BBMD9), a novel synthetic derivative of berbamine, inhibited the proliferation of MM cells in dose- and time-dependent manners. Flow cytometric (FCM) analysis revealed that MM cells were arrested in the G1 phase and that apoptotic cells increased in a time-dependent manner. Moreover, the BBMD9 treatment downregulated IKKα and IKKβ, inhibited p-IκBα, and blocked p65 nuclear localization. Consistently, NF-κB downstream targets, such as cyclinD1 and survivin, were also reduced. In addition, BBMD9 phosphorylated the activity of JNK and c-Jun.

Abstract
UNLABELLED Certain members of the Arenaviridae family are category A agents capable of causing severe hemorrhagic fevers in humans. Specific antiviral treatments do not exist, and the only commonly used drug, ribavirin, has limited efficacy and can cause severe side effects. The discovery and development of new antivirals are inhibited by the biohazardous nature of the viruses, making them a relatively poorly understood group of human pathogens. We therefore adapted a reverse-genetics minigenome (MG) rescue system based on Junin virus, the causative agent of Argentine hemorrhagic fever, for high-throughput screening (HTS). The MG rescue system recapitulates all stages of the virus life cycle and enables screening of small-molecule libraries under biosafety containment level 2 (BSL2) conditions. The HTS resulted in the identification of four candidate compounds with potent activity against a broad panel of arenaviruses, three of which were completely novel. The target for all 4 compounds was the stage of viral entry, which positions the compounds as potentially important leads for future development. IMPORTANCE The arenavirus family includes several members that are highly pathogenic, causing acute viral hemorrhagic fevers with high mortality rates. No specific effective treatments exist, and although a vaccine is available for Junin virus, the causative agent of Argentine hemorrhagic fever, it is licensed for use only in areas where Argentine hemorrhagic fever is endemic. For these reasons, it is important to identify specific compounds that could be developed as antivirals against these deadly viruses.

Abstract
Colon cancer is one of the most common malignancies, causes considerable morbidity and mortality. The current treatment for colon cancer is more modest than had been hoped. There is an urgent clinical need to explore new agents or adjuvants for colon cancer treatment. Natural products and their derivates act as one of the major source for anticancer agent. In the present study, we investigated the anti-proliferation and chemoprevention effects of tetrandrine (Tet) on colon cancer cells to uncover the possible molecular basis of this effect. We found that Tet can inhibit proliferation and induce apoptosis in LoVo cells. With dimethylhydrazine (DMH) and dextran sodium sulfate (DSS) induced colon cancer model, we found that Tet can prevent or inhibit DMH plus DSS induced aberrant crypt foci (ACF) and colon cancer formation, as well as suppress tumor growth in the xenograft colon cancer model. Tet can downregulate the expression of IGFBP-5 in LoVo cells. Exogenous expression of IGFBP-5 can attenuate the anti-cancer activity of Tet, while IGFBP-5 knockdown potentiates this effect of Tet on LoVo cells. Tet can inhibit Wnt/β-catenin signaling transduction, which can be partly reversed by exogenous expression of IGFBP-5, but is enhanced by IGFBP-5 knockdown. Our results demonstrated that the anticancer activity of Tet in colon cancer cells may be mediated partly by downregulating the expression of IGFBP-5, thus inactivating Wnt/β-catenin signaling transduction.

Abstract
Tetrandrine, a bisbenzylisoquinoline alkaloid, is known to inhibit tumor cell proliferation and induce apoptosis in cancer models in vitro and in vivo. In the present study, tetrandrine significantly inhibited the proliferation of mouse endothelial cells (EOMA cell) and induced G1/S arrest in EOMA cells, in which the expressions of cyclin D and cyclin E and CDKs were downregulated. Tetrandrine treatment also caused intracellular accumulation of reactive oxygen species (ROS). Pretreatment with NAC, which is a ROS inhibitor, blocked G1/S cell arrest and cyclin regulation induced by tetrandrine, implying that ROS generation plays an important role in tetrandrine-induced cell cycle arrest. Furthermore, a decreased phospho-Akt protein level after tetrandrine treatment was reversible with the removal of the intracellular ROS by NAC. Notably, overexpression of Akt decreased tetrandrine-induced G1/S arrest. Finally, we verified the antiangiogenic effects of tetrandrine in vivo in a liver cancer xenograft model in nude mice. In conclusion, tetrandrine inhibits EOMA cell growth through the ROS/Akt pathway, and it could be a promising compound for cancer therapy as an inhibitor of tumor vascular growth.

Abstract
Tetrandrine, a constituent of Chinese herb Stephania tetrandra, causes cell death in prostate cancer, but the molecular mechanisms leading to apoptosis is not known. Here we demonstrated that tetrandrine selectively inhibits the growth of prostate cancer PC3 and DU145 cells compared to normal prostate epithelial PWR-1E cells. Tetrandrine-induced cell death in prostate cancer cells is caused by reactive oxygen species (ROS)-mediated activation of c-Jun NH2-terminal kinase (JNK1/2). JNK1/2-mediated proteasomal degradation of c-FLIPL/S and Bcl2 proteins are key events in the sensitization of prostate cancer cells to Fas- and mitochondria-mediated apoptosis by tetrandrine. Tetrandrine-induced JNK1/2 activation caused the translocation of Bax to mitochondria by disrupting its association with Bcl2 which was accompanied by collapse of mitochondrial membrane potential (MMP), cytosolic release of cytochrome c and Smac, and apoptotic cell death. Additionally, tetrandrine-induced JNK1/2 activation increased the phosphorylation of Bcl2 at Ser70 and facilitated its degradation via the ubiquitin-mediated proteasomal pathway. In parallel, tetrandrine-mediated ROS generation also caused the induction of ligand-independent Fas-mediated apoptosis by activating procaspase-8 and Bid cleavage. Inhibition of procaspase-8 activation attenuated the cleavage of Bid, loss of MMP and caspase-3 activation suggest that tetrandrine-induced Fas-mediated apoptosis is associated with the mitochondrial pathway. Furthermore, most of the signaling effects of tetrandrine on apoptosis were significantly attenuated in the presence of antioxidant N-acetyl-l-cysteine, thereby confirming the involvement of ROS in these events. In conclusion, the results of the present study indicate that tetrandrine-induced apoptosis in prostate cancer cells is initiated by ROS generation and that both intrinsic and extrinsic pathway contributes to cell death.

Abstract
Cissampelos sympodialis Eichl is a plant from the Northeast and Southeast of Brazil. Its root infusion is popularly used for treatment of inflammatory and allergic diseases. We investigated whether warifteine, its main alkaloid, would have anti-inflammatory effect due to a blockage of neutrophil function. In vivo warifteine treatment inhibited casein-induced neutrophil migration to the peritoneal cavity but did not inhibit neutrophil mobilization from the bone marrow. Analysis of the direct effect of warifteine upon neutrophil adherence and migration in vitro demonstrated that the alkaloid decreased cell adhesion to P and E-selectin-transfected cells. In addition, fLMP-induced neutrophil migration in a transwell system was blocked by warifteine; this effect was mimicked by cAMP mimetic/inducing substances, and warifteine increased intracellular cAMP levels in neutrophils. The production of DNA extracellular traps (NETs) was also blocked by warifteine but there was no alteration on PMA-induced oxidative burst or LPS-stimulated TNFα secretion. Taken together, our data indicate that the alkaloid warifteine is a potent anti-inflammatory substance and that it has an effect on neutrophil migration through a decrease in both cell adhesion and migration.

Abstract
Lysosomes are acidic organelles that have a crucial role in degrading intracellular macromolecules and organelles during the final stage of autophagy. Tetrandrine (Tet), a bisbenzylisoquinoline alkaloid, was reported as an autophagy activator. Here, in contrast with previous studies, we show that Tet is a potent lysosomal deacidification agent and is able to block autophagic flux in the degradation stage. Single-agent Tet induces significant apoptosis both in vitro and in xenograft models. In the presence of Tet, apoptosis was preceded by a robust accumulation of autophagosomes and an increased level of microtubule-associated protein 1 light chain 3, type II (LC3-II). However, Tet increased the level of sequestosome 1 and decreased the turnover of LC3, indicating the blockade of autophagic flux in the degradation stage. As blockade of autophagic flux decreases the recycling of cellular fuels, Tet reduces the uptake of glucose in cancer cells. These effects lead to insufficient substrates for tricarboxylic acid (TCA) cycle and impaired oxidative phosphorylation. Blunting autophagosome formation using 3-methyladenine or genetic knockdown of Beclin-1 failed to rescue cells upon Tet treatment. By contrast, addition of methyl pyruvate to supplement TCA substrates protected Tet-treated tumor cells. These results demonstrate that energetic impairment is required in Tet-induced apoptosis. Tet, as a potent lysosomal inhibitor, is translatable to the treatment of malignant tumor patients.

Abstract
BACKGROUND Berberis vulgaris is a well known plant with traditional herbal medical history. The aims of this study was to bioscreen and compare the in vitro biological activity (antioxidant, cholinergic, antidaibetic and the anticancer) of barberry crude extract and berberine active compound. METHODS The effect of B. vulgaris extract and berberine chloride on cellular thiobarbituric acid reactive species (TBARS) formation, diphenyle-α-picrylhydrazyl (DPPH) oxidation, cellular nitric oxide (NO) radical scavenging capability, superoxide dismutase (SOD), glutathione peroxidase (GPx), acetylcholinesterase (AChE) and α-gulcosidase activities were spectrophotometrically determined. On the other hand, the effect of extract and berberine as anticancer was estimated on three different cell lines which were MCF-7, HepG-2, and Caco-2 cells by using neutral red uptake assay which compared with control normal cells (PBMC). RESULTS Our results showed that barberry crude extract contains 0.6 mg berberine/mg crude extract. Barberry extract showed potent antioxidative capacity through decreasing TBARS, NO and the oxidation of DPPH that associated with GPx and SOD hyperactivation. Inhibitory effect of berberis crude extract on α-glucosidase was more potent than that of berberine chloride, while both had the same AChE inhibitory effect. Besides, different concentrations of both berberine chloride and barberry ethanolic extract showed to have no growth inhibitory effect on normal blood cells (PBMC). Otherwise, both berberine chloride and barberry ethanolic extract showed to have inhibitory effect on the growth of breast, liver and colon cancer cell lines (MCF7, HepG2 and CACO-2, respectively) at different incubation times starting from 24 hrs up to 72 hrs and the inhibitory effect increased with time in a dose dependent manner. CONCLUSION This work demonstrates the potential of the barberry crude extract and its active alkaloid, berberine, on suppressing lipid peroxidation, suggesting a promising use in the treatment of hepatic oxidative stress, Alzheimer and idiopathic male factor infertility. Beside, berberis vulgaris ethanolic extract is safe non-toxic extract as it was not inhibit the growth of PBMC that can induce cancer cell death that could return to its powerful antioxidant activity.

Abstract
Tetrandrine, a bisbenzylisoquinoline alkaloid component of broadly used traditional Chinese medicine, has antitumor effects against some cancers. In our study, we investigated the effects of tetrandrine on the human hepatocellular carcinoma (HCC) in vitro and in vivo. The results showed that tetrandrine effectively induced apoptosis of liver cancer cell in a dose- and time-dependent manner accompanied by alteration of cell morphology, chromatin fragmentation and caspase activation. Tetrandrine treatment also induced intracellular accumulation of reactive oxygen species (ROS), and ROS scavengers (LNAC and GSH) completely blocked the effects of tetrandrine-induced apoptosis, suggesting that the generation of ROS plays an important role in tetrandrine-induced apoptosis. Although the activities of JNK and ERK were inhibited significantly by tetrandrine treatment, JNK and ERK are not involved in the tetrandrine-induced apoptosis. In contrast, Akt activity was found to be closely related to tetrandrine-induced apoptosis. The data demonstrated that Akt activity inhibitor LY294002 synergistically promoted tetrandrine-induced apoptosis of HCC, whereas ectopic expression of Akt contrastly abrogated partial of the tetrandrine-induced apoptosis. These data suggest that Akt signal is the downstream event of ROS generation in the tetrandrine-induced HCC cell apoptosis. Moreover, the results of xenograft in nude mice were consistent with that of the in vitro studies. Therefore, our data suggest that tetrandrine may be a promising agent for the treatment of HCC as a regulator of ROS/Akt pathway.

Abstract
One hundred twenty-six 19-d-old male broiler chickens were used to determine the effects of berberine on the magnitude of the acute inflammatory response induced by Escherichia coli lipopolysaccharide (LPS). The birds were weighed and randomly allotted to 1 of 3 treatments at d 19 (3 treatments x 7 replicates x 6 birds). The treatments comprised a control group in which saline was injected at d 21, an LPS-treated group in which LPS (3 mg/kg of BW) was injected at d 21, and finally a berberine and LPS-treated group in which berberine (15 mg/kg of BW) was orally administered from d 19 to d 24 with LPS injection (3 mg/kg of BW) at d 21. Injection of LPS alone decreased (P < 0.01) weight gain, feed intake, and feed conversion compared with the control and the berberine-administered group. Relative liver weight was increased (P < 0.05) in the LPS-treated group 72 h postinjection compared with the control and the berberine-treated group. Total counts of white blood cells and lymphocytes were also increased (P < 0.05) in the LPS-treated group 72 h postinjection. The heterophil concentration of the LPS-treated group was greater (P < 0.05) than that of both the control and the berberine-administered group 24 h postinjection. Broilers in the LPS-treated group had greater (P < 0.05) total serum protein compared with birds in the control and the berberine-administered group both 24 and 72 h postinjection. In addition, the plasma interleukin-6 level of the LPS-treated group was significantly elevated (P < 0.01) at 24 h compared with that of the control and the berberine-administered group. Our results indicate that LPS injection initiated a series of physiological changes typical of an acute phase response in broiler chickens. These effects were largely mitigated by oral administration of berberine.

Abstract
Tetrandrine (TET), a bis-benzylisoquinoline alkaloid isolated from the dried root of Hang-Fang-Chi (Stephania tetrandra S. Moore), is well known to possess activities including antioxidant, anti-inflammation, anti-fibrotic and anticancer. It is used clinically to treat hypertension and silicosis. In the present study, the anti-proliferative and apoptotic effects of TET were evaluated on three different hepatoma cell lines, namely Hep G2, PLC/PRF/5 and Hep 3B. Using XTT assay, results showed that the IC50 values of TET were 4.35 microM for Hep G2, 9.44 microM for PLC/PRF/5 and 10.41 microM for Hep 3B cells. The CC50 of TET against BNL-CL.2 mouse normal liver cells was 31.12 microM. Interestingly, TET exhibited a lower IC50 value and better selectivity against Hep G2 and PLC/PRF/5 cells than cisplatin. Microscopic observation study, DNA fragmentation assay and flow cytometric analysis further supported apoptotic effect of TET on both PLC/PRF/5 and Hep 3B cells. The cell cycle of PLC/PRF/5 treated with TET appeared to arrest at G2/M phase in a dose-dependent manner, whereas no effect was noted on the cell cycle of Hep 3B cells. The present study concludes that TET exhibited anti-proliferative effect on Hep G2, PLC/PRF/5 and Hep 3B cells in a dose-dependent manner. TET also possesses a lower IC50 and better SI value than cisplatin against Hep G2 and PLC/PRF/5 cells. The effect of TET on cell cycle progression was found to vary with the type of hepatoma cells, suggesting the genetic make-up of the cells play an important role in the response to drug treatment.

Abstract
Crude preparations of Stephania tetrandra (ST), a traditional herbal medicine, have been used safely for arthritis and silicosis in China. The concentration of granulocyte elastase - alpha 1 protease inhibitor complex in plasma is enhanced in inflammatory processes, e.g. in septicaemia and rheumatoid arthritis (RA), being an expression of granulocyte activation during inflammatory response. It has previously been reported that ST showed beneficial and immunomodulatory effects in the treatment of relatively mild RA. After the administration of ST for 12 weeks, the proportion of granulocytes and the granulocyte count in peripheral blood decreased significantly. The lipid peroxide and human granulocyte elastase levels of stored plasma declined significantly. Furthermore, both the leukocyte/elastase ratio and granulocyte/elastase ratio increased significantly. The findings of this study suggest that the suppressive effect of ST administration on excessive granulocyte activation resulted in the improvement of inflammation with rheumatoid arthritis.

Abstract
Roots and barks of various Berberis species are used as folk remedy for the treatment of various inflammatory diseases such as lumbago, rheumatism and to reduce fever. Six isoquinoline alkaloids namely berberine, berbamine, palmatine, oxyacanthine, magnoflorine, and columbamine were isolated as the main components of alkaloidal fraction from the roots of Turkish Berberis species and effects were studied using various in vivo models in mice. All alkaloids inhibited inflammations in varying degrees, among them berberine, berbamine and palmatine were shown to possess significant and dose-dependent inhibitory activity against serotonin-induced hind paw oedema both on oral and topical applications and acetic acid-induced increase in vascular permeability on oral administration. Moreover, these three alkaloids were also shown to possess dose-dependent antinociceptive activity, which assessed by using the model based on the inhibition of p-benzoquinone-induced writhing movements as well as antipyretic activity on FCA-induced increased rectal temperature on subacute administration. However, all alkaloids induced gastric lesions in varying degrees.

Abstract
Extracts obtained from the roots and barks of various Berberis species are used as folk remedy worldwide for the treatment of various inflammatory ailments including lumbago, rheumatism and to reduce fever. Effects of the extracts and fractions from the roots of Berberis crataegina DC. (Berberidaceae) were studied using various in vivo models of inflammation in mice and rats and observed potent inhibitory activity against carrageenan- and serotonin-induced hind paw oedema, acetic acid-induced increased vascular permeability, castor oil-induced diarrhoea, and Freund's complete adjuvant-induced (FCA) arthritis models. Through bioassay-guided fractionation berberine was isolated as the main active ingredient. Moreover, a dose-dependent analgesic activity was determined, which assessed by using the model based on the inhibition of acetic acid-induced writhing reflexes, as well as antipyretic activity on FCA-induced increased body temperature. Acute and subchronic toxicity studies were also performed.

Abstract
Complement-mediated mode of action of bisbenzylisoquinoline alkaloid fangchinoline was investigated in vivo and in vitro. The application of fangchinoline intraperitoneally (i.p.) to complement normal mice, strain ICR, inhibited the complement activity in serum and peritoneal exudate. The substance activated serum complement of C5-deficient DBA/2 mice. Fangchinoline was able to provoke local inflammatory reaction in both strains after subcutaneous (s.c.) injection. The alkaloid suppressed paw swelling induced by live Candida albicans in ICR and DBA/2 mice. Its effect depended on the dose and time of injection prior to inflammatory reaction. The in vitro experiments proved the interference of fangchinoline action with post-C5 reactions. The substance augmented C5-convertase formation and functional activity. These results are in correspondence with our previous investigations, proving the complement-mediated action of fangchinoline. The antiinflammatory effect could be a consequence of the caused complement exhaustion.

Abstract
The ability of aporphinoid alkaloid oxoglaucine to influence T- and B-cell immune response was studied in mice models. The substance inhibited in vitro mitogen-induced lymphocyte proliferation and suppressed antibody response to sheep red blood cells (SRBC) and lipopolysaccharide (LPS) in vivo effectively. The action depended on the relative timing of antigen and oxoglaucine administration. The substance manifested stimulatory effect in popliteal lymph node (PLN) reaction and LPS-induced B-cell activation. In the chronic inflammatory model of adjuvant arthritis oxoglaucine exhibited stimulatory or suppressive action related to the kinetics of the process. At low doses (1 or 2 mg kg-1) oxoglaucine improved the outcome of Klebsiella pneumoniae infection, while at higher doses (10 or 20 mg kg-1) the substance caused an impairment of host resistance to infectious agent. The comparison with cyclophosphamide in some tests showed that oxoglaucine was effective in manifold lower doses. In conclusion, oxoglaucine exerted immunomodulatory effects in vivo in a dose-dependent and protocol-dependent manner. Yet, its overall action might be attributed to the different sensitivity of the cells involved in the developing immune response.

Abstract
Coriolus versicolor polysaccharide peptide (CVP) and the bis-benzylisoquinoline alkaloids, tetrandrine (TET) and berbamine (BER), the active ingredients isolated from Chinese medicinal herbs known to possess antitumor activities, concentration-dependently inhibited the proliferation of human leukemic HL-60 cells. CVP did not affect the growth of normal human peripheral blood lymphocytes (PBL), whereas TET elicited concentration-dependent cytotoxic effects. Morphological observation and DNA analysis revealed that CVP elicited no effect on the morphological features of HL-60 cells and did not cause DNA fragmentation, but TET and BER caused cell shrinkage with the formation of apoptotic bodies, and showed clear evidence of DNA fragmentation. These findings indicate that TET and BER, but not CVP, inhibited the proliferation of HL-60 cells via induction of apoptosis.

Abstract
The antimicrobial and immunological properties of ethanol extracts, non-alkaloid, tertiary alkaloid and quaternary alkaloid fractions, obtained from roots and aerial parts of Isopyrum thalictroides were examined. The non-alkaloid fraction from aerial parts inhibited the growth of seven test microorganisms and was the most effective suppressor of classical pathway (CP) complement activity in normal human serum (NHS) and guinea pig serum (GPS). The alkaloid fractions, containing quaternary alkaloids expressed suppressive effect on mitogen-induced splenocyte proliferation. The in vitro antibody response against sheep red blood cells (anti-SRBC) was inhibited by ethanol extracts and quaternary alkaloid fraction. The intraperitoneal (i.p.) application of ethanol extract and tertiary alkaloid fraction from aerial parts showed that they possess in vivo effect on alternative pathway (AP) complement activity, anti-SRBC response and delayed type hypersensitivity (DTH).

Abstract
Extracts obtained from the roots of Berberidaceae species have been used in Eastern and Bulgarian folk medicine in rheumatic and other chronic inflammatory disorders. The investigations of the chemical composition and immunological properties show that their activity is mainly due to the alkaloid constituents. In the present study the anti-inflammatory properties of total ethanol extract (TEE), three alkaloid fractions, a major alkaloid berberine and oxyacanthine isolated from Berberis vulgaris roots were compared. All these were applied in acute inflammation (carrageenan- and zymosan-induced paw oedema), as the TEE showed the highest reducing effect. Their ability to alter in vivo and in vitro complement activity was determined. Also, the TEE was most effective in a chronic inflammatory model of adjuvant arthritis. The protoberberine fractions Bv2, Bv3 and berberine suppressed a delayed type hypersensitivity (DTH) reaction. Fraction Bv1 and berberine diminished antibody response against SRBC in vivo. The in vitro treatment of splenocytes with berberine showed that the anti-SRBC antibody synthesis was influenced in a different manner depending on the time course of its application. Oxyacanthine was less effective than berberine in the tests used.

Abstract
1. Previously it has been shown that tetrandrine (TET), a bis-benzylisoquinoline alkaloid, isolated from a Chinese herb Stephania tetrandra, can block non-voltage-operated Ca2+ entry activated by intracellular Ca2+ store depletion induced by thapsigargin (TSG) and can release intracellular Ca2+ in HL-60 cells. The present study attempted to identify the chemical group(s) of the TET molecule responsible for these dual effects. The effects of TET and its closely related analogues, hernandezine (HER) and berbamine (BER), on Ca2+ entry and Ca2+ release were compared in fura-2-loaded HL-60 cells. 2. Berbamine was much less potent (IC50 = 200 mumol/L) than TET and HER (both IC50 values = 25 mumol/L) in inhibiting Ca2+ entry activated by TSG. Furthermore, at 100 mumol/L, BER was much less effective than TET and HER in suppressing TSG-induced Mn2+ entry. At 30-100 mumol/L, BER was significantly less effective than both TET and HER in causing Ca2+ release from internal stores. However, only BER was able to cause store depletion-activated Ca2+ entry (or the so-called 'capacitative Ca2+ entry') upon Ca2+ readmission. 3. Taken together, the data from this structure-activity relationship study reveal that the -OCH3 group of one particular benzene ring of TET, which distinguishes TET from BER, in part produces the dual pharmacological actions of TET.

Abstract
Tetrandrine was shown to significantly inhibit uveitis induced by endotoxin and interleukin-1 alpha (IL-1 alpha) in rats. The dose-response curve of IL-1 alpha-induced uveitis was inhibited in a non-competitive manner. The maximum inflammation induced by IL-1 alpha was suppressed to 58.4%, 38.3% and 18.3% of the control peak by 5 mg/kg, 10 mg/kg and 20 mg/kg t.i.d. of tetrandrine, respectively. The maximum inflammation induced by endotoxin was suppressed to 56.5% and 38.0% by 5 mg/kg and 10 mg/kg t.i.d. of tetrandrine, respectively. The mechanism of tetrandrine's anti-inflammation could involve numerous pathways of inflammation processes and multiple inflammatory mediators. The results of this study indicate that tetrandrine appears to be a broad spectrum, non-steroidal, novel ocular anti-inflammatory agent.

Abstract
Extensive pharmacological investigations on tetrandrine, one of the traditional medicinal alkaloids, are reviewed. Tetrandrine has been used clinically in China for centuries in the treatment of many diseases. A recent series of studies has revealed major mechanisms underlying its multiple pharmacological and therapeutic actions. One of the most interesting discoveries is that tetrandrine is a new kind blocker of the voltage-activated, L-type Ca2+ channel in a variety of excitable cells, such as cardiac, GH3 anterior pituitary and neuroblastoma cells, as well as in rat neurohypophysial nerve terminals. Although tetrandrine does not belong to any of the three classical Ca2+ channel blocker groups, electrophysiological and radioligand binding studies show that tetrandrine is an L-type Ca2+ channel blocker with its binding site located at the benzothiazepine receptor on the alpha 1-subunit of the channel. In addition, tetrandrine is a blocker of the voltage-dependent T-type Ca2+ channel. It is clear that tetrandrine's actions in the treatment of cardiovascular diseases, including hypertension and supraventricular arrhythmia, are due primarily to its blocking of voltage-activated L-type and T-type Ca2+ channels. Furthermore, this alkaloid is a potent blocker of the Ca(2+)-activated K+ (K(Ca)) channels of neurohypophysial nerve terminals. The blocking kinetics of tetrandrine on the K(Ca) channel is quite different from that of typical K(Ca) channel blockers such as tetraethylammonium and Ba2+. Although the clinical role of tetrandrine as a blocker of the K(Ca) channels is unclear, it is a promising ligand for the study of K(Ca) channel function.

Abstract
Two isoquinoline plant alkaloids, tetrandrine (1) and berbamine (2), have been evaluated for anti-inflammatory activity in an acute paw oedema assay and in adjuvant-induced arthritis in rats. 1 but not 2 suppressed the chronic inflammation in the arthritis model but neither compound was active in the acute inflammation assay. In the adjuvant-induced polyarthritis, 1 was not effective when given at the time of inoculation (Day 0), nor just before (Day 7-10) signs of arthritis were evident. However, when given on a therapeutic dose schedule (Days 10-13) or continually (Day -1 to +14) on a prophylactic schedule, signs of arthritis including weight loss due to cachexia were significantly reduced. Given orally, 1 was considerably more potent than aspirin but not gastro-irritant and may be a promising lead for the development of a safe and effective treatment of chronic inflammatory diseases.

Abstract
The bisbenzylisoquinoline alkaloid berbamine has been used in China and Japan for the therapy of leukopaenic complications of cancer. Mice treated with non-toxic doses showed significant enhancement of neutrophil and lymphocyte counts in the circulation, but a decrease in the numbers of bone marrow stem cells in a dose-dependent manner after two weeks. Similar findings were observed in cyclophosphamide-treated mice. These results indicate that berbamine acts by stimulating the maturation and release of leukocyte progenitors, and may have value in leukopaenic patients.

Abstract
The bisbenzylisoquinoline analogues, tetrandrine and berbamine, were investigated for their effects on guineapig airway microvascular leakage, an animal model of asthma and allergic inflammation. Significant inhibition of microvascular leakage by tetrandrine was observed with all four allergic mediators used in these experiments. By contrast, berbamine was able to suppress microvascular leakage induced by platelet-activating factor and bradykinin, but not by leukotriene D4 or histamine. These results indicate that tetrandrine has broad-spectrum inhibitory activity on allergic mediators, and may have value for the therapy of diseases in which these mediators have a role in pathogenesis.

Abstract
Delayed administration of tetrandrine, a novel broad-spectrum anti-inflammatory agent, to BB rats at a dosage schedule of 20 mg kg-1 day-1 from 79 days of age reduced the cumulative incidence of diabetes from 73.1 to 41.7% (p < 0.01). Brief treatment with the potent immunosuppressive agent FK506 at a dosage schedule of 0.5 mg kg-1 day-1 from 79 days of age for 5 days had no significant effect on the cumulative incidence of diabetes (66.7%, p > 0.1). However, the combination of tetrandrine and FK506 in the afore-mentioned dosage schedules reduced the incidence of diabetes to only 3.6% (p < 0.001). These results suggest that the strong synergy between tetrandrine and FK506 may offer a safe and effective therapeutic strategy for the treatment of patients with recent onset or imminent IDDM.

Abstract
The bisbenzylisoquinoline (BBI) alkaloids, chondocurine, tetrandrine, isotetrandrine and cepharanthine, were tested for immunosuppressive activity in mice. A plaque-forming cell (PFC) response to a T-cell-dependent antigen, sheep red blood cell, was significantly suppressed by a 7 day treatment of chondocurine or tetrandrine at 1 mg/kg/day and of isotetrandrine at 50 mg/kg/day, but not suppressed by cepharanthine treatment. The suppressive effect of chondocurine was greater when it was given after immunization rather than before or concurrently. However, it did not affect the PFC response to a T-cell-independent antigen, lipopolysaccharide. A delayed-type hypersensitivity was also suppressed by chondocurine treatment. There was no significant change in lymphocyte number and proportion of T-cell subsets in the BBI alkaloid-treated mice. These data suggest that there is selective inhibition by chondocurine and tetrandrine of the T-cell-dependent immune reactions.

Abstract
The effects of the bisbenzylisoquinoline alkaloids tetrandrine and berbamine on the action of IL-1, TNF and PAF were investigated in the rat subcutaneous air pouch model of inflammation. Both compounds were equipotent in the suppression of leukocyte infiltration into air pouches induced by IL-1 and TNF, with ED50 values in the range 20-30 mg/kg/3 days. Both were also equipotent in suppression of PMN infiltration induced by PAF with ED50 values in the same range as that for IL-1 and TNF. However, tetrandrine was more potent than berbamine as a suppressant of PAF-induced MNC infiltration, but much less potent than berbamine in carageenen-induced PMN infiltration. These results suggest that these bisbenzylisoquinolines may have value in the therapy of chronic inflammatory diseases where IL-1, TNF and PAF have a role in pathogenesis.

Abstract
This paper focuses on eosinophil activation and its selective inhibition. Superoxide anion (O2-) production by human eosinophils, an indicator of their activation, was induced by a variety of activators. Several compounds which are known to inhibit protein kinase C (staurosporine, K252a, sphingosine) inhibited O2- production induced by phorbol ester (PMA) but failed to inhibit O2- production induced by IgG coupled to Sepharose beads. Inhibition of O2- production by other agents (plasma-activated zymosan, fMLP, and leukotriene B4 (LTB4), was intermediate. By contrast, wortmannin, a compound which has been previously reported to inhibit O2- production in neutrophils via a protein kinase-independent pathway, potently inhibited O2- production in eosinophils which had been activated by IgG and by Platelet-Activating Factor but was virtually inactive against PMA-induced O2- production. Taken together, the results indicate that, as a minimum, there must be two pathways of induction of O2- production in eosinophils. Moreover, the intermediate levels of inhibition in cells which had been activated with serum-activated zymosan, FMLP, and LTB4 suggest that these agents may either be acting via both of these pathways or that yet other pathways may exist.

Abstract
Tetrandrine and berbamine are bisbenzylisoquinoline compounds which differ from each other in a minor way in terms of chemical structure, yet tetrandrine is 6-18 times more potent than berbamine in terms of inhibitory effects on production of interleukin-1 and tumor necrosis factor (TNF alpha) by monocytes and macrophages, and TNF beta production by lymphocytes. Moreover, tetrandrine significantly suppressed phosphoinositide turnover while berbamine did not. These findings may provide important insights into structure-activity relationships and the design of novel analogues and congeners useful in the therapy of chronic inflammatory and auto-immune diseases.

Abstract
Comparison of the bisbenzylisoquinolines tetrandrine and berbamine shows that both drugs are equipotent in terms of enhancement of antibody responses and suppression of delayed-type hypersensitivity (DTH) responses to sheep red blood cell antigens. Both compounds are also equally active when given to mice during the induction and expression phases of DTH. Using a model of experimental brucellosis in mice, it was found that both compounds did not affect antibody responses, while they caused equipotent suppression of DTH. By contrast, berbamine but not tetrandrine caused significant suppression of spleen weight. Also, berbamine caused a significantly greater enhancement of spleen colony counts of Brucella abortus than tetrandrine. Short-term toxicology studies showed no toxic effects at bioactive doses.

Abstract
A novel flavonoid compound baohuoside-1 (3,5,7-trihydroxy-4'-methoxyl-8-prenylflavone-3-O-alpha-L-rhamnopy ranoside) was investigated for immunopharmacological properties in vitro. The results show that baohuoside-1 has significant suppressive effects on neutrophil chemotaxis, mitogen-induced lymphocyte transformation, mixed-lymphocyte culture, NK-cell cytotoxicity and IL-2 production. These dose-dependent inhibitory effects were found to be significant at concentrations of less than 1 microgram/ml, compared with greater than 94% cell viability at concentrations of 10 micrograms/ml. These results suggest that baohuoside-1 may have potential as an anti-inflammatory/immunosuppressive agent.

Abstract
Tetrandrine, a bisbenzylisoquinoline alkaloid, was found to cause death of malignant lymphoid and myeloid cells but not of Epstein-Barr virus-transformed lymphoblastoid cells. The death took the form of apoptosis (programmed cell death), the nature of the process being confirmed by DNA gel electrophoresis and electron microscopy. The induction of apoptosis by tetrandrine was much more rapid in CEM-C7 cells (4 h) than in the same cells treated with glucocorticoids (40 h), and did not require de novo protein synthesis. These results suggest that the anti-inflammatory and immunosuppressive properties of tetrandrine are mediated by novel mechanisms worthy of further investigation. They also indicate that tetrandrine may have value as an anti-neoplastic agent.
