In vitro toxicity of latex, its terpenoidal fractions and isolated phorbol esters from Euphorbia umbellata (Pax) Bruyns on monocytic and melanoma cells. Fitoterapia 2024; 176:105987. [PMID: 38703916 DOI: 10.1016/j.fitote.2024.105987] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2023] [Revised: 04/26/2024] [Accepted: 05/01/2024] [Indexed: 05/06/2024]
Abstract
In Brazil, latex from Euphorbia umbellata (African milk tree) has been increasingly used in folk medicine to treat several types of cancer, including melanoma. The effect of lyophilized latex (LL), its hydroethanolic extract (E80), triterpene (F-TRI)- and diterpene (F-DIT)-enriched fractions, along with six isolated phorbol esters from LL and phorbol 12-myristate 13-acetate (PMA) on J774A.1, THP-1, SK-MEL-28, and B16-F10 cell line viability were evaluated by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) method. The compounds were identified by 2D-NMR and HRESIMS. The effect of the LL, extract and fractions on cell viability was also assessed through a resazurin reduction assay. At 100 μg/ml, LL, and its fractions moderately inhibited J774A.1 (37.5-59.5%) and THP-1 (12.6-43.6%) metabolism. LL (IC50 70 μg/ml) and F-TRI (IC50 68 μg/ml) were barely more effective against B16-F10 cells, and only F-TRI exerted an inhibitory effect on SK-MEL-28 cells (IC50 66-75 μg/ml). The samples did not effectively inhibit THP-1 growth (IC50 69-87 μg/ml, assessed by MTT). B16-F10 was susceptible to PMA (IC50 53 μM) and two 12-phenylacetate esters (IC50 56-60 μM), while SK-MEL-28 growth was inhibited (IC50 58 μM) by one of these kinds of esters with an additional 4β-deoxy structure. Synagrantol A (IC50 39 μM) was as effective as PMA (IC50 47 μM) in inhibiting J774A.1 growth in a dose-dependent manner. Furthermore, an in silico study with target receptors indicated a high interaction of the compounds with the PKC proteins. These results provide useful knowledge on the effect of tigliane-type diterpenes on tumor cell from the perspective of medicinal chemistry.

Abstract
Endophytic fungi live asymptomatically inside vegetal tissues, and such uncommon habitat contributes to their exceptional chemical diversity. Isolating natural products from endophytic fungi could fail due to silent biosynthetic gene clusters under ordinary in vitro culture conditions, and co-culturing has been assayed to trigger their metabolism. We carried out single and dual cultures with 13 endophyte strains isolated from Euphorbia umbellata leaves. Multivariate statistics applied to untargeted metabolomics compared the chemical profiles of all endophyte cultures. PCA analysis guided the selection of the Aspergillus pseudonomiae J1 - Porogramme brasiliensis J9 dual culture for its most significant chemical differentiation: Five compounds were putatively annotated in the J1-J9 culture according to UHPLC-HRMS data, kojic acid, haliclonol and its diastereoisomer, caffeic acid, and 2-(3,4-dihydroxyphenyl)acetaldehyde. Analysis by PLS-DA using VIP score showed that kojic acid displayed the most significative importance in discriminating single and dual J1-J9 cultures.

Abstract
Cells use glycans to encode information that modulates processes ranging from cell-cell recognition to programmed cell death. This information is encoded within a glycocode, and its decoding is performed by carbohydrate-binding proteins. Among these, lectins stand out due to their specific and reversible interaction with carbohydrates. Changes in glycosylation patterns are observed in several pathologies, including cancer, where abnormal glycans are found on the surfaces of affected tissues. Given the importance of the bioprospection of promising biomolecules, the current work aimed to determine the structural properties and anticancer potential of the mannose-specific lectin from seeds of Canavalia villosa (Cvill). Experimental elucidation of the primary and 3D structures of the lectin, along with glycan array and molecular docking, facilitated the determination of its fine carbohydrate-binding specificity. These structural insights, coupled with the lectin's specificity, have been combined to explain the antiproliferative effect of Cvill against cancer cell lines. This effect is dependent on the carbohydrate-binding activity of Cvill and its uptake in the cells, with concomitant activation of autophagic and apoptotic pathways.

Abstract
The species Euphorbia umbellata has been used to treat inflammatory diseases, cancer, and ulcers. Biological activities reported in the literature, including antiproliferative, cytotoxic and anti-inflammatory, are attributed to the chemical constituents present in its composition as terpenes and polyphenolic compounds. The most recurrently verified metabolites in the Euphorbiaceae family plant species are terpenes, of which euphol is a major constituent with broadly reported cytotoxic, antinociceptive and anti-inflammatory effects; it frequently appears in various extracts obtained from the plant. Euphol has a documented inhibitory effect on neutrophil chemotaxis and can modulate the complement system. Since complement system activation is intimately intertwined with autoimmune and inflammatory diseases, tumor growth promotion and metastasis, plant metabolites from Euphorbia umbellata might influence the outcomes of inflammatory processes. We believe that this is the first review presenting the current knowledge on Euphorbia umbellata secondary metabolites and their biological activities.

Abstract
Nowadays, quinoline scaffold is among the most vital construction compounds for the development of new drugs. The purpose of this research is to evaluate the anti-cancer activity of sodium salt of ethyl (E)-2-cyano-3-(7-hydroxy-4-methyl-2-oxoquinoline-1(2H)-yl)-3-(4-hydroxyphenyl) acrylate against Ehrlich ascites carcinoma (EAC) cells residing in female mice's peritoneal cavity. The docking study exhibited a favourable interaction between the compound and the receptors 1MOY and 3KJF of osteopontin and caspase 3, respectively. The compound's sodium salt showed potential antioxidant and anti-cancer effects against Ehrlich ascites carcinoma (EAC) cells in vivo. Herein, the results elucidated that treatment with the compound's sodium salt exerted significant chemopreventive and chemotherapeutic effects, which reduced both EAC cell volume and count. Our results revealed that treatment with the sodium salt of the compound demonstrated a remarkable in vivo apoptotic effect through elevation of the expression of caspase 3 and reduction of osteopontin levels. Histopathological examination confirmed that the compound's sodium salt improved liver and kidney tissues without any apparent adverse effects.

Abstract
Prostatic cancer (PC) stands out in terms of its occurrence, pathophysiology, and unfavorable prognostics in humans and dogs. Natural drugs bear an integrative potential for conventional antineoplastic treatments. In this context, the bioproducts of Synadenium grantii have been empirically used in different parts of Brazil for the integrative treatment of prostate cancer in humans. However, there is no availability of scientific evidence of the antitumor effects of S. grantii. Therefore, this study aimed to investigate the bioactive compounds in the latex of S. grantii using the high-resolution mass spectrophotometry (HRMS) and to evaluate its cytotoxic effects on primary canine PC cell cultures. Four fragments of phorbol ester were identified as potential bioactive compounds using the HRMS. With the help of an MTT ([3-(4,5-dimethyldiazol-2-yl)-2,5 diphenyltetrazolium bromide]) assay, two canine prostatic carcinoma cell lines (PC 1 and PC2) showed a decrease in the tumor cell count, with an Inhibitory concentration 50 (IC50)of 0.8469 and 0.6068 mg/ml, respectively, for PC1 and PC2. In conclusion, the latex of S. grantii contains phorbol esters in its composition, and its aqueous solution has a cytotoxic effect on canine metastatic PC cells in vitro.

Abstract
An integrated microscopic study of the destruction of mouse Ehrlich ascites carcinoma (EAC) cells under starvation conditions has been carried out. It has been found that, in addition to apoptosis, necrosis, and apoptotic necrosis, already known for EAC, cell destruction can also occur through mitochondrial autolysis, which is proposed to be considered a new kind of mitoptosis. A mitoptosis in EAC is characterized by the appearance of many autolyzing mitochondria, the fusion of which leads to rupture of the cell membrane and the ejection of the nucleus from the cell. It is assumed that the polymorphism of EAC destruction patterns is explained by the different physiological state of the cells, which determines the "choice" of the cell death mechanism. This situation poses a challenge for researchers to develop complex inducers with the ability to stimulate all possible types of cancer cell death.

Abstract
Breast cancer is the most prevalent cancer in women affecting about 12% of world's female population. It is a multifactorial disease, mostly invasive in nature. Diosgenin and related compounds are potent antiproliferative agents. Carbamate derivatives have been synthesized at C26 of furostene ring after opening spiroketal bond (F-ring) of diosgenin. Compound 10 possessed significant antiproliferative activity against human breast cancer cells by arresting the population at G1 phase of cell division cycle and induced apoptosis. Induction of apoptosis was observed through the caspase signalling cascade by activating caspase-3. Moreover, carbamate 10 exhibited moderate antiinflammatory activity by decreasing the expression of cytokines, TNF-α and IL-6 in LPS-induced inflammation in primary macrophage cells. Furthermore, compound 10 significantly reduced Ehrlich ascites carcinoma significantly in mice. It was well tolerated and safe in acute oral toxicity in Swiss albino mice. The concomitant anticancer and antiinflammatory properties of carbamate 10 are important and thus, can further be optimized for a better anti-breast cancer candidate.

Abstract
AIM To study the potential use of nanoformulations of curcumin (CUR); CUR-loaded pluronic nanomicelles (CURnp1), and CUR-loaded poly(lactic-co-glycolic acid) nanoparticles (CURnp2) as antitumor agents in Ehrlich ascites carcinoma-bearing animals, and their mechanism of action. MATERIALS & METHODS CURnp1 and CURnp2 were prepared, characterized and tested against Ehrlich ascites carcinoma-bearing mice. Superoxide dismutase, catalase (CAT), glutathione, malondialdehyde, histopathological, immunohistochemical studies, cell cycle and caspase-3 were investigated. RESULTS & CONCLUSION CURnp1 destroyed tumors via increasing superoxide dismutase, CAT and glutathione, decreasing malondialdehyde through inducing apoptosis by decreasing Ki-67 and Bcl2 expression and activating caspase-3 leading to inhibition of proliferation and cell cycle arrest with progression at G1/S phase. The study demonstrated for the first time superiority of CURnp1 over native CUR and CURnp2 as anticancer agents.

Abstract
Aim: This study aimed to evaluate, for the first time the potential use of a safe biocompatible nanoformulation of silymarin (SM) as antitumor agent and to provide its mechanism of action compared with native SM. Materials & methods: SM was loaded into pluronic nanomicelles and Ehrlich ascites carcinoma-tumor-bearing mice were used as experimental model. Biochemical parameters including SOD, CAT and GSH, lipid peroxidation biomarkers (MDA), histopathological, ultrastructural and immunohistochemical studies were applied on the Ehrlich ascites carcinoma cells. Furthermore, the cell cycle as well as caspase-3 were examined. Results & conclusion: Nanoformulated SM (SMnp) destroyed tumors via increasing SOD, CAT and GSH concomitant with decreasing MDA. Moreover, SMnp-induced apoptosis through decreasing Ki-67 and Bcl2 expression, along with the activation of caspase-3, leads to inhibition of proliferation and the arrest of ceel cycle progression at the G1/S phase. Electron microscopy studies presented the superiority of SMnp over native SM in causing mitochondrial and nuclear degeneration in cancer cells.

The novel piperazine-containing compound LQFM018: Necroptosis cell death mechanisms, dopamine D 4 receptor binding and toxicological assessment. Biomed Pharmacother 2018; 102:481-493. [PMID: 29579709 DOI: 10.1016/j.biopha.2018.02.120] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2017] [Revised: 02/21/2018] [Accepted: 02/23/2018] [Indexed: 01/12/2023] Open
Abstract
Piperazine is a promising scaffold for drug development due to its broad spectrum of biological activities. Based on this, the new piperazine-containing compound LQFM018 (2) [ethyl 4-((1-(4-chlorophenyl)-1H-pyrazol-4-yl)methyl)piperazine-1-carboxylate] was synthetized and some biological activities investigated. In this work, we described its ability to bind aminergic receptors, antiproliferative effects as well as the LQFM018 (2)-triggered cell death mechanisms, in K562 leukemic cells, by flow cytometric analyses. Furthermore, acute oral systemic toxicity and potential myelotoxicity assessments of LQFM018 (2) were carried out. LQFM018 (2) was originally obtained by molecular simplification from LASSBio579 (1), an analogue compound of clozapine, with 33% of global yield. Binding profile assay to aminergic receptors showed that LQFM018 (2) has affinity for the dopamine D4 receptor (Ki = 0.26 μM). Moreover, it showed cytotoxicity in K562 cells, in a concentration and time-dependent manner; IC50 values obtained were 399, 242 and 119 μM for trypan blue assay and 427, 259 and 50 μM for MTT method at 24, 48 or 72 h, respectively. This compound (427 μM) also promoted increase in LDH release and cell cycle arrest in G2/M phase. Furthermore, it triggered necrotic morphologies in K562 cells associated with intense cell membrane rupture as confirmed by Annexin V/propidium iodide double-staining. LQFM018 (2) also triggered mitochondrial disturb through loss of ΔΨm associated with increase of ROS production. No significant accumulation of cytosolic cytochrome c was verified in treated cells. Furthermore, it was verified an increase of expression of TNF-R1 and mRNA levels of CYLD with no involviment in caspase-3 and -8 activation and NF-κB in K562 cells. LQFM018 (2) showed in vitro myelotoxicity potential, but it was orally well tolerated and classified as UN GHS category 5 (LD50 > 2000-5000 mg/Kg). Thus, LQFM018 (2) seems to have a non-selective action considering hematopoietic cells. In conclusion, it is suggested LQFM018 (2) promotes cell death in K562 cells via necroptotic signaling, probably with involvement of dopamine D4 receptor. These findings open new perspectives in cancer therapy by use of necroptosis inducing agents as a strategy of reverse cancer cell chemoresistance.

Abstract
An expression of calpain and caspase-1 as well as the concomitant ultrastructural alterations were investigated during necrosis of the mouse Ehrlich ascites carcinoma. The calpain expression was registered at 0 h and 1 h although caspase-1 did not induce any signals during these time periods. The rise of the cytoplasmic lytic zones contacted by calpain antibodies was identified as a morphologic event corresponding to the expression of calpain. Lytic zone's distribution followed by the appearance of the calpain/caspase-1 clusters assigned for lysis of the Golgi vesicles and ER. Also, the microapocrine secretion of the vesicles containing the calpain/caspase-1 clusters was detected. Further, the lysis of the plasma membrane occurred due to progression of intracellular lysis. Rupture of the plasma membrane resulted in the termination of secretion and dissemination of cell contents. The nuclei still had their normal shape. Nuclear lysis continued to rise with intranuclear lytic zones, of which the progression was accompanied with the presence of calpain/caspase-1 clusters. The data contribute to the concept of the initial role of calpain for tumor cell destruction, provide first evidence of the calpain/caspase-1 pathway in tumor cells, and highlight microapocrine secretion as a possible tumor cell death signalling mechanism.

Abstract
Eutirucallin is a lectin isolated from the latex of Euphorbia tirucalli, a plant known for its medical properties. The present study explores various characteristics of Eutirucallin including stability, cytotoxicity against tumor cells, antimicrobial and antiparasitic activities. Eutirucallin was stable from 2 to 40 days at 4°C, maintained hemagglutinating activity within a restricted range, and showed optimal activity at pH 7.0–8.0. Eutirucallin presented antiproliferative activity for HeLa, PC3, MDA-MB-231, and MCF-7 tumor cells but was not cytotoxic for non-tumorigenic cells such as macrophages and fibroblasts. Eutirucallin inhibited the Ehrlich ascites carcinoma in vivo and it was also observed that Eutirucallin inhibited 62.5% of Escherichia coli growth. Also, Eutirucallin showed to be effective when tested directly against Toxoplasma gondii infection in vitro. Therefore, this study sheds perspectives for pharmacological applications of Eutirucallin.

Abstract
The objective of this study was to evaluate the cytotoxic activity of rosemary (REO, Rosmarinus officinalis L.), turmeric (CEO, Curcuma longa L.), and ginger (GEO, Zingiber officinale R.) essential oils in HeLa cells. Cytotoxicity tests were performed in vitro, using tetrazolium (MTT) and neutral red assays for evaluation of antiproliferative activity by different mechanisms, trypan blue assay to assess cell viability and evaluation of cell morphology for Giemsa to observe the cell damage, and Annexin V to evaluate cell death by apoptosis. CEO and GEO exhibited potent cytotoxic activity against HeLa cells. IC50 obtained was 36.6 μg/mL for CEO and 129.9 μg/mL for GEO. The morphology of HeLa cells showed condensation of chromatin, loss of cell membrane integrity with protrusions (blebs), and cell content leakage for cells treated with CEO and GEO, from the lowest concentrations studied, 32.81 μg/mL of CEO and 32.12 μg/mL of GEO. The Annexin V assay revealed a profile of cell death by apoptosis for both CEO and GEO. The results indicate cytotoxic activity in vitro for CEO and GEO, suggesting potential use as anticancer agents for cervical cancer cells.

Abstract
CONTEXT Eugenia dysenterica DC. (Myrtaceae) has been widely used in the folk medicine and it presents phytochemicals constituents associated to antioxidant properties. OBJECTIVE The objective of this study was to investigate the protective effects of E. dysenterica leaf hydroalcoholic extract (EDE) in vitro and in vivo using AMJ2-C11 cells and Swiss mice exposed to hexavalent chromium [Cr(VI)], respectively. MATERIALS AND METHODS AMJ2-C11 cells were pretreated with EDE and exposed to Cr(VI) to evaluate cytotoxicity and the pathways involved in the chemopreventive effects of the extract. Mice were daily pretreated with EDE and then exposed to Cr(VI). Survival analysis, histopathological examination and determination of Cr levels in biological tissues were carried out. RESULTS In vitro studies showed that pretreatment of the AMJ2-C11 cells with EDE protected against the cytotoxicity and oxidative stress induced by Cr(VI). Consequently, the pretreatment with EDE reduced reactive oxygen species and apoptosis triggered by Cr(VI), probably by a marked antioxidant and chelating activities demonstrated by EDE. Regarding in vivo studies, pretreatment for 10 days with EDE increased survival of the mice exposed to Cr(VI). In addition, EDE prevented liver and kidney pathological damages, in parallel with reduction in chromium levels found in these organs and plasma. EDE also showed a marked antioxidant potential associated with the presence of polyphenols, especially flavonoids and tannins, as confirmed by HPLC-PDA. CONCLUSION The study showed that EDE protects against Cr(VI)-induced damage in vitro and in vivo supporting further studies for the development of therapeutic products applied to prevent the damage induced by toxic metals, especially Cr(VI).

Abstract
Synadenium grantii is frequently used for the treatment of various diseases such as allergies, gastric disorders, and especially cancer. The aim of this study was to evaluate the possible antiproliferative potential of the methanol extract, fractions, and pure compounds from the stems of S grantii Phytochemical analysis was carried out by conventional chromatographic techniques, and the antiproliferative activity was analyzed using the sulforhodamine B assay and an MTT-based assay. Nonpolar fraction and its subfractions from the stems of S grantii exhibited promising cytostatic effect against several human tumor cell lines (glioma, breast, kidney, and lung), with total grown inhibition values ranging from 0.37 to 2.9 μg/mL. One of the active principles of this plant was identified as a rare phorbol diterpene ester, denoted as 3,4,12,13-tetraacetylphorbol-20-phenylacetate. This compound demonstrated antiproliferative activity against glioma, kidney, lung, and triple-negative breast cancer cell lines. These results demonstrate that S grantii stems produce active principles with relevant antiproliferative potential.

A series of cis-imidazoline analogues, termed nutlins, were reported to displace the recombinant p53 protein from its complex with MDM2 by binding to MDM2 in the p53 pocket, and exhibited an antitumour activity both in vitro and in vivo. Thus, the purpose of this study was to evaluate the antitumour properties of LQFM030 (2), a nutlin analogue created by employing the strategy of molecular simplification. METHODS LQFM030 (2) cytotoxicity was evaluated in Ehrlich ascites tumour (EAT) cells, p53 wild type, by the trypan blue exclusion test, and the mechanisms involved in EAT cell death were investigated by light and fluorescence microscopy, flow cytometry, real-time PCR and Western blotting. KEY FINDINGS Our results demonstrate that LQFM030 has dose-dependent antiproliferative activity and cytotoxic activity on EAT cells, induces the accumulation of p53 protein and promotes cell cycle arrest and apoptosis. p53 gene transcription was unaffected by LQFM030 (2); however, MDM2 mRNA increased and MDM2 protein decreased. CONCLUSIONS These results suggest that the small-molecule p53 activator LQFM030 (2) has the potential for further development as a novel cancer therapeutic agent.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Euphorbia umbellata latex (sap) has normally been used in folk medicine in southern Brazil to treat different types of cancers. AIM OF STUDY To carry out a biomonitored investigation of partitioned latex using in vitro assay, to identify the main mechanisms related with the action of the most active fraction as well as to develop a phytochemical study with this material. MATERIALS AND METHODS Biological screening was performed with hexane, chloroform, ethyl acetate and methanol fractions from the latex of E. umbellata using MTT, trypan blue, and neutral red assays to determine the cytotoxicity against HRT-18, HeLa and Jurkat cells and flow cytometry, DNA quantification, acridine orange and Hoechst 33342 staining to investigate mechanisms of action for the hexane extract. The phytochemical study of the hexane fraction was performed by chromatographic procedures and the substances were identified by NMR analysis. The isolated terpenes were evaluated using MTT to determine the cytotoxicity against Jurkat cells. RESULTS All the fractions presented concentration and time dependent cytotoxicity. The hexane fraction showed the highest cytotoxicity; whereas the Jurkat cell was the lineage with the highest sensitivity (IC50 1.87µg/mL). Fragmentation of DNA and apoptosis are two mechanisms related with the toxicity of hexane fraction. The hexane fraction arrested the cell cycle in the G0/G1 phase, and the selectivity index was 4.30. Phytochemical study of the hexane fraction led to isolation of euphol (main compound) and germanicol acetate. Both substances demonstrated some slight cytotoxic activity against Jurkat cells after 72h; however the activity was minimal compared to vincristine (anticancer standard drug). CONCLUSION The current research proves that the fractions of the latex from E. umbellata have a cytotoxic effect against three different cancer cells lines. The hexane fraction showed high in vitro cytotoxic effects against Jurkat cells demonstrating that the effect may be due to non-polar constituents. The two isolated terpenes (euphol and germanicol acetate) showed poor cytotoxic activity indicating that the anticancer properties of the extract may be caused by other substances present in the hexane fraction.

Abstract
BACKGROUND Ehrlich ascites carcinoma is the one of the animal cancer models having high malignancy and rapid growth resistance. Silibin has reported to be an antioxidant in previous studies. We aimed to investigate the effects of silibin on mouse liver with Ehrlich ascites tumor (EAT) cells in different time periods. METHODS Balb/c mice were divided into five groups. Group I (Control): The saline buffer (sb) was injected intraperitoneally (ip) to the mice for 15 days. Group II (Silibin): 150mg/kg silibin was injected ip for 15 days. Group III (Ehrlich): 2×10(5) cells were transferred from the donor mouse to healthy mice on first day. Group IV (Ehrlich+Silibin): Silibin was given between 5th and 15th days to mice inoculated with EAT. Group V (Silibin+Ehrlich): Silibin was injected for 15 days after EAT cells. The liver sections were stained with matrix metalloproteinase-2 and -9 (MMP-2 and MMP-9), caspase 3, caspase 8, and proliferating cell nuclear antigen (PCNA) antibodies by the streptavidin-biotin-peroxidase technique. Biochemical analysis and Terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick-end labeling (TUNEL) method were performed in the liver. RESULTS Superoxide dismutase levels of liver increased in Ehrlich+Silibin group compared with Ehrlich group. Malondialdehyde levels significantly decreased in Silibin+Ehrlich group compared with Ehrlich+Silibin. MMP-2 and MMP-9 immunopositive cells increased in Silibin+Ehrlich compared with Ehrlich group. Caspase 3 and TUNEL signals significantly increased in Silibin+Ehrlich group compared with Ehrlich group. PCNA positive signals significantly increased in Ehrlich+Silibin group compared with Ehrlich group. CONCLUSION According to our findings, we suggest that silibin treatment after EAT cells inoculation has more effective than concurrently EAT and silibin treatment.

Abstract
Campomanesia adamantium (Myrtaceae) is an antioxidant compounds-rich Brazilian fruit popularly known as gabiroba. In view of this, it was evaluated the hepatoprotective effects of pulp (GPE) or peel/seed (GPSE) hydroalcoholic extracts of gabiroba on injured liver-derived HepG2 cells by CCl4 (4 mM). The results showed the presence of total phenolic in GPSE was (60%) higher when compared to GPE, associated with interesting antioxidant activity using DPPH• assay. Additionally, HPLC chromatograms and thin layer chromatography of GPE and GPSE showed the presence of flavonoids. Pretreatment of HepG2 cells with GPE or GPSE (both at 800–1000 μg/mL) significantly (p < 0.0001) protected against cytotoxicity induced by CCl4. Additionally, the cells treated with both extracts (both at 1000 μg/mL) showed normal morphology (general and nuclear) contrasting with apoptotic characteristics in the cells only exposed to CCl4. In these experiments, GPSE also was more effective than GPE. In addition, CCl4 induced a marked increase in AST (p < 0.05) and ALT (p < 0.0001) levels, while GPE or GPSE significantly (p < 0.0001) reduced these levels, reaching values found in the control group. In conclusion, the results suggest that gabiroba fruits exert hepatoprotective effects on HepG2 cells against the CCl4-induced toxicity, probably, at least in part, associated with the presence of antioxidant compounds, especially flavonoids.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Synadenium grantii Hook f. has traditionally been used to treat various neoplastic diseases in southern Brazil. AIM OF STUDY Evaluation of the antitumoural potential of Synadenium grantii latex against B16F10 melanoma cell line using in vitro and in vivo models, as well as a phytochemical study of the latex. MATERIALS AND METHODS The in vitro antitumoural activity was performed using MTT and trypan blue assays with different latex concentrations (1.7 µg-7.0 µg/well and 1.22 mg-4.88 mg/well). Flow cytometry was used to determine the progression of the cell cycle. The in vivo activity was performed by subcutaneously injecting melanoma cells in the dorsum of C57BL6 mice, followed by treating the mice with a popular form of use of the latex (garrafada) administered orally. After sacrificing the animals, histological analysis of the organs was performed by hematoxylin-eosin staining. The phytochemical study of the latex was performed by NMR and chromatographic procedures and the extracts and isolated substances were evaluated by IR, 1D and 2D NMR analysis. RESULTS The Synadenium grantii latex exhibited decreased cell viability of the melanoma line in a concentration and time-dependent manner, and also cell cycle arrest in the S-G2/M phase. The latex caused a 40% reduction in the volume of tumours of the mice with melanomas. Histological examination of the organs of these animals showed no differences between groups. The phytochemical investigation resulted in the isolation and identification of triterpene euphol and the steroid citrostadienol, which were tested against the strain of melanoma. Euphol showed no antitumoural activity, while the steroid citrostadienol showed reduced cytotoxic activity. CONCLUSION The Synadenium grantii latex presented in vitro and in vivo cytotoxic effects with antitumoural activity against B16F10 melanoma cells.

Abstract
Plukenetia volubilis Linneo, or Sacha inca, is an oleaginous plant from the Euphorbiaceae family. The aim of this work was to perform a chemical and biological analysis of different leaf extracts from P. volubilis such as aqueous extract (AEL), methanol (MEL), ethanol (EEL), chloroform (CEL), and hexane (HEL). Thin layer chromatography analysis revealed the presence of phenolic compounds, steroids, and/or terpenoídes. Furthermore, the antioxidant activities were analyzed by in vitro assays and their effects on cell lineages by in vivo assays. The Total Antioxidant Capacity (TCA) was expressed as equivalent ascorbic acid (EEA/g) and it was observed that the extracts showed values ranging from 59.31 to 97.76 EAA/g. Furthermore, the DPPH assay values ranged from 62.8% to 88.3%. The cell viability assay showed that the extracts were able to reduce viability from cancer cells such as HeLa and A549 cells. The extracts MEL and HEL (250 µg/mL) were able to reduce the proliferation of HeLa cells up to 54.3% and 48.5%, respectively. The flow cytometer results showed that these extracts induce cell death via the apoptosis pathway. On the other hand, the extracts HEL and AEL were able to induce cell proliferation of normal fibroblast 3T3 cells.

Abstract
Chronic myeloid leukemia (CML) is a clonal myeloproliferative disease that shows apoptosis resistance. The introduction of imatinib mesylate has revolutionized the treatment of CML, but imatinib resistance may develop at any time and inevitably leads to disease progression. Synadenium umbellatum Pax. belongs to the Euphorbiaceae family and is popularly used in Brazil for the treatment of cancer. The cytotoxicity of Euphorbiaceae is associated with the ability of these plants and their bioactive compounds to induce apoptotic tumor cell death. Therefore, we aimed to investigate the cytotoxicity and the mechanisms of death induced by S. umbellatum extract in leukemic cells. S. umbellatum cytotoxicity was evaluated by trypan blue exclusion assay and flow cytometric analysis of the cell cycle; the mechanisms involved in K-562 cell death were investigated by light microscopy and flow cytometry. The results demonstrate that S. umbellatum is cytotoxic to leukemic cells in a concentration-dependent manner. Morphological analysis revealed that S. umbellatum treatment induced K-562 cell death by an apoptotic pathway. Furthermore, data indicate ROS overproduction, alterations in mitochondrial membrane potential, phosphatidylserine externalization and activation of caspase 9. Taken together, the results demonstrate that S. umbellatum extract arrested the cell cycle and triggered apoptosis at several levels in K-562 cells.
