[PMID: 38301920 DOI: 10.1016/j.tiv.2024.105786] [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: 07/26/2023] [Revised: 12/28/2023] [Accepted: 01/25/2024] [Indexed: 02/03/2024]
Abstract
Gliomas are among the most common primary malignant brain tumors. Despite advances in cancer treatment, survival is very low, so the discovery of new therapeutic agents is essential. In this context, indole is an important source for the development of new bioactive molecules. A pharmacological screening of ten indole derivatives was carried out to evaluate the cytotoxic capacity against three tumor cell lines. After pharmacological screening, three compounds were selected, based on their high capacity to reduce cell proliferation, and their IC50 values were determined. Compound 9 exhibited the highest cytotoxic activity (IC50 = 0.4 μg/mL) in gliomas (C6 cell line), and were selected for further experiments. C6 cells were treated with compound 9 to evaluate cellular mechanisms such as colony formation and cell migration capacity and morphological alterations. Compound 9 decreased clone formation (0.4 and 0.8 μg/mL), and inhibited migration (0.2-0.8 μg/mL) in C6 cells. Morphological changes in cells treated with the compound 9 were also observed, such as chromatin condensation, and disorganization in cellular stress beams. Indole derivatives had a cytotoxic effect on tumor cells, and compound 9 showed the best anti-proliferative and anti-migratory activity in glioma cells.

Abstract
PURPOSE The treatment of leishmaniasis, an anthropozoonosis caused by Leishmania protozoa, is limited by factors, such as adverse effects, toxicity, and excessive cost, which has highlighted the importance of novel drugs. In this context, natural products have been considered as sources of antileishmanial agents. This study investigated the leishmanicidal activity of Microgramma vacciniifolia frond lectin (MvFL) on promastigotes and amastigotes of Leishmania amazonensis. METHODS The effects of MvFL on promastigote proliferation and macrophage infection by amastigotes were evaluated and mean inhibitory concentrations (IC50) were calculated. As a safety assessment, the hemolytic capacity of MvFL (6.25-200 µg/mL) against mouse and human erythrocytes was determined. Additionally, the ability of MvFL (6.25-100 µg/mL) to modulate lysosomal and phagocytic activities and the nitric oxide (NO) production by murine peritoneal macrophages was also investigated. RESULTS After 24 h, MvFL inhibited the proliferation of L. amazonensis promastigotes, with an IC50 of 88 µg/mL; however, hemolytic activity was not observed. MvFL also reduced macrophage infection by amastigotes with an IC50 of 52 µg/mL. Furthermore, treatment with MvFL reduced the number of amastigotes internalized by infected murine peritoneal macrophages by up to 68.9% within 48 h. At a concentration of 25 µg/mL, MvFL stimulated lysosomal activity of macrophages within 72 h, but did not alter phagocytic activity or induce NO production at any of the tested concentrations. CONCLUSION MvFL exerts antileishmanial activity and further studies are needed to assess its therapeutic potential in in vivo experimental models of leishmaniasis.

Abstract
BACKGROUND Lung cancer is the deadliest type of cancer in the world and the search for compounds that can treat this disease is highly important. Lawsone (2-hydroxy-1,4-naphtoquinone) is a naphthoquinone found in plants from the Lawsone genus that show a high cytotoxic effect in cancer cell lines and its derivatives show an even higher cytotoxic effect. METHODS Sulforhodamine B was used to evaluate the cytotoxic activity of compounds on tumor cells. Clonogenic assay was used to analyze the reduction of colonies and wound healing assay to the migratory capacity of A549 cells. Apoptosis and necrosis were analyzed by flow cytometer and Giemsa staining. Hemolysis assay to determine toxicity in human erythrocytes. RESULTS Lawsone derivatives were evaluated and compound 1 (O-propargyllawsone) was the one with the highest cytotoxic effect, with IC50 below 2.5 µM in A549 cells. The compound was able to reduce colony formation and inhibit cell migration. Morphological changes and cytometry analysis show that the compound induces apoptosis and necrosis in A549 cells. CONCLUSIONS These results show that O-propargyllawsone show a cytotoxic effect and may induce apoptosis in A549 cells.

Abstract
Natural products have played a pivotal role for the discovery of anticancer drugs. Tonantzitlolones are flexibilan-type diterpenes rare in nature; therefore, few reports have shown antiviral and cytotoxic activities. This study aimed to investigate the in vivo antitumor action of Tonantzitlolone B (TNZ-B) and its toxicity. Toxicity was evaluated in mice (acute and micronucleus assays). Antitumor activity of TNZ-B (1.5 or 3 mg/kg intraperitoneally - i.p.) was assessed in Ehrlich ascites carcinoma model. Angiogenesis and reactive oxygen species (ROS) and nitric oxide (NO) production were also investigated, in addition to toxicological effects after 7-day treatment. The LD50 (lethal dose 50%) was estimated at around 25 mg/kg (i.p.), and no genotoxicity was recorded. TNZ-B reduced the Ehrlich tumor's volume and total viable cancer cell count (p < 0.001 for both). Additionally, TNZ-B reduced peritumoral microvessel density (p < 0.01), suggesting antiangiogenic action. Moreover, a decrease was observed on ROS (p < 0.05) and nitric oxide (p < 0.001) levels. No significant clinical findings were observed in the analysis of biochemical, hematological, and histological (liver and kidney) parameters. In conclusion, TNZ-B exerts antitumor and antiangiogenic effects by reducing ROS and NO levels and has weak in vivo dose-repeated toxicity. These data contribute to elucidate the antitumor action of TNZ-B and point the way for further studies with this natural compound as an anticancer drug.

Abstract
BACKGROUND Protease inhibitors have been isolated from plants and present several biological activities, including immunomodulatory action. OBJECTIVE This work aimed to evaluate a Moringa oleifera flower trypsin inhibitor (MoFTI) for acute toxicity in mice, hemolytic activity on mice erythrocytes and immunomodulatory effects on mice splenocytes. METHODS The acute toxicity was evaluated using Swiss female mice that received a single dose of the vehicle control or MoFTI (300 mg/kg, i.p.). Behavioral alterations were observed 15-240 min after administration, and survival, weight gain, and water and food consumption were analyzed daily. Organ weights and hematological parameters were analyzed after 14 days. Hemolytic activity of MoFTI was tested using Swiss female mice erythrocytes. Splenocytes obtained from BALB/c mice were cultured in the absence or presence of MoFTI for the evaluation of cell viability and proliferation. Mitochondrial membrane potential (Δψm) and reactive oxygen species (ROS) levels were also determined. Furthermore, the culture supernatants were analyzed for the presence of cytokines and nitric oxide (NO). RESULTS MoFTI did not cause death or any adverse effects on the mice except for abdominal contortions at 15-30 min after administration. MoFTI did not exhibit a significant hemolytic effect. In addition, MoFTI did not induce apoptosis or necrosis in splenocytes and had no effect on cell proliferation. Increases in cytosolic and mitochondrial ROS release, as well as Δψm reduction, were observed in MoFTI-treated cells. MoFTI was observed to induce TNF-α, IFN-γ, IL-6, IL-10, and NO release. CONCLUSION These results contribute to the ongoing evaluation of the antitumor potential of MoFTI and its effects on other immunological targets.

Abstract
Pyrazine, a kojic acid having hydroxypyrone, and hydroquinone are the head compounds of
different categories possessing a broad range of biological activities including anticancer and antioxidant
activities, thus are interested in evaluating the cytotoxicity on K562 human leukemia cells and
radical scavenging activities of these compounds in bonding together as ester compounds. Four hydroxypyrone
containing-2-pyrazinoic esters along with hydroquinone containing-one were synthesized
and characterized by spectral data. The cytotoxicity of these compounds on K562 human leukemia
cells and free Radical scavenging activities were evaluated. The K562 cells were treated with various
concentrations of each compound for a different time and cell viabilities were determined by MTT viability
assay. It was observed that all compounds decreased the viability of the human leukemia K562
cells in a dose- and time-dependent manner. Hydroquinone pyrazinoate 4a with an IC50 value of
50±8.0 µM was the most active compound against the K562 cells. The compounds 4b and 4e showed
higher cytotoxicity on K562 cells respectively after 72 h. Antioxidant activities of the compounds were
evaluated by DPPH free radical scavenging assay. Hydroquinone ester 4a showed higher activity with
an IC50 value of 0.82 mM than those of hydroxypyrone derivatives of which maltol pyrazinoate 4e
showed the highest inhibition with IC50 value of 4.7 mM. Although free hydroxyl group of kojic acid
was masked by ester group, 4b and 4e showed significant scavenging activities, as the same result was
observed in the case of hydroquinone ester.

Abstract
BACKGROUND The genus Pamburus (Rutaceae) comprises the only species, Pamburus missionis (Wight) Swingle. Pamburus missionis is traditionally used in the treatment of swellings, chronic rheumatism, paralysis and puerperal diseases. PURPOSE The present study investigates the cancer chemotherapeutic potential of essential oil (EO) from P. missionis. METHODS EO was isolated by steam distillation and chemical composition was determined by GC-MS. Cell viability was used to detect cytotoxic activity. Mechanism of cell death was studied using Annexin V-FITC/PI binding, cell cycle analysis, measurement of MMP and ROS generation by flow cytometry. Expression of apoptosis related proteins was investigated by western blot. RESULTS GC-MS analysis of the essential oil revealed the presence of 51 components. The major components were β-Caryophyllene, 4(14),11-Eudesmadiene, Aromadendrene oxide-(2) and Phytol. EO inhibited the growth and colony formation ability of A431 and HaCaT cells. EO treatment induced nuclear condensation and loss of membrane integrity, DNA fragmentation, increase in sub-G1 DNA content and increase in intracellular ROS level. Inhibition of intracellular ROS by ascorbic acid and N-acetyl cysteine treatment blocked EO induced apoptosis, revealing that apoptotic activity was by ROS accumulation. EO induced apoptosis was found to be due to the loss of mitochondrial membrane potential (ΔΨm), increase in Bax/Bcl-2 ratio, release of cytochrome c and activation of caspases (cleaved form of caspase-3, caspase-8, caspase-9) and by PARP cleavage. CONCLUSION The present study revealed cancer chemotherapeutic potential of EO from P. missionis. EO induces cell death through intrinsic (mitochondrial) and extrinsic apoptotic pathway in A431 and HaCaT cells. These results suggest that EO could be used as a potential therapeutic agent for the treatment of skin epidermoid cancer.

Abstract
Thymus vulgaris, (Lamiaceae), essential oils composition and yield, were found to be greatly influenced by water stress and growth enhancers. Therefore, three controlled cultivation conditions were applied to achieve the highest essential oil productivity of T. vulgaris. The essential oils obtained by hydro-distillation of the aerial parts were analyzed using (GC-MS). The tested plant subjected to drought showed a 66% increase in the essential oil yield, while those subjected to drought stress and foliar spray showed 57.1% increase and the regularly irrigated group with foliar spraying showed 23.8% increase relative to the control group. The cytotoxic activity of T. vulgaris essential oils was evaluated against lung (A-549), colon (HCT-116), intestinal (CACO2) and breast (MCF-7) carcinoma using the cell viability assay. The lowest IC50 values 0.44 and 0.33 μg/mL were seen against (HCT-116) and (CACO2) cells respectively. These IC50 values were lower than that of doxorubicin used as reference drug.

Abstract
Background The essential oil from Mesosphaerum sidifolium (L’Hérit.) Harley & J.F.B.Pastore (syn. Hyptis umbrosa), Lamiaceae (EOM), and its major component, have been tested for toxicity and antitumor activity. Methods EOM was obtained from aerial parts of M. sidifolium subjected to hydro distillation, and gas chromatography-mass spectrometry was used to characterize the EOM chemical composition. The toxicity was evaluated using haemolysis assay, and acute toxicity and micronucleus tests. Ehrlich ascites carcinoma model was used to evaluate the in vivo antitumor activity and toxicity of EOM (50, 100 and 150 mg/kg), and fenchone (30 and 60 mg/kg) after 9 d of treatment. Results The EOM major components were fenchone (24.8%), cubebol (6.9%), limonene (5.4%), spathulenol (4.5%), β-caryophyllene (4.6%) and α-cadinol (4.7%). The HC50 (concentration producing 50% haemolysis) was 494.9 μg/mL for EOM and higher than 3000 μg/mL for fenchone. The LD50 for EOM was approximately 500 mg/kg in mice. The essential oil induced increase of micronucleated erythrocytes only at 300 mg/kg, suggesting moderate genotoxicity. EOM (100 or 150 mg/kg) and fenchone (60 mg/kg) reduced all analyzed parameters (tumor volume and mass, and total viable cancer cells). Survival also increased for the treated animals with EOM and fenchone. For EOM 150 mg/kg and 5-FU treatment, most cells were arrested in the G0/G1 phase, whereas for fenchone, cells arrested in the S phase, which represents a blockage in cell cycle progression. Regarding the toxicological evaluation, EOM induced weight loss, but did not induce hematological, biochemical or histological (liver and kidneys) toxicity. Fenchone induced decrease of AST and ALT, suggesting liver damage. Conclusions The data showed EOM caused in vivo cell growth inhibition on Ehrlich ascites carcinoma model by inducing cell cycle arrest, without major changes in the toxicity parameters evaluated. In addition, this activity was associated with the presence of fenchone, its major component.

A new acridine derivative induces cell cycle arrest and antiangiogenic effect on Ehrlich ascites carcinoma model. Biomed Pharmacother 2017; 90:253-261. [PMID: 28364597 DOI: 10.1016/j.biopha.2017.03.049] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2016] [Revised: 03/07/2017] [Accepted: 03/18/2017] [Indexed: 01/12/2023] Open
Abstract
BACKGROUND Acridine derivatives, including amsacrine, have antitumor activity. However, side effects, development of resistance and their low bioavailability, have limited their use. Herein, we described the synthesis, and evaluated the toxicity and antitumor activity of a new amsacrine analogous, the N'-(2-chloro-6-methoxy-acridin-9-yl)-2-cyano-3-(4-dimethylaminophenyl)-acrilohidrazida (ACS-AZ10). METHODS The compound was obtained in a linear pathway where the ASC-Az intermediate was obtained by coupling of 6,9-dichloro-3-methoxy-acridine and 2-ciany-acethohidrazide followed by condensation with the corresponding aldehyde. The toxicity of ACS-AZ10 was evaluated in mice using acute toxicity and micronucleus assays. Ehrlich ascites carcinoma model was used to investigate the antitumor activity and toxicity of ACS-AZ10 (7.5, 15 or 30mg/kg, i.p.), after nine days of treatment. Cell cycle and angiogenesis were also evaluated. RESULTS The ASC-AZ10 was obtained with satisfactory yields and its structure was confirmed by spectroscopic and spectrometric techniques. On acute toxicity study, ACS-AZ10 (2000mg/kg, i.p.) induced transient depressant effects on central nervous system. The LD50 was approximately 2500mg/kg. ACS-AZ10 (15 or 30mg/kg) displayed significant antitumor activity considering the tumor weight and volume, cell viability, and total Ehrlich cell count. ACS-AZ10 (7.5mg/kg) induced an increase in sub-G1 peak, suggesting apoptosis. At 15mg/kg ACS-AZ10 induced cell cycle arrest in G2/M phase and a reduction in the percentage of cells in G0/G1 and S phases, suggesting a pre-mitotic blockade. ACS-AZ10 reduced the microvessel density, indicating an antiangiogenic effect. Weak hematological, biochemical and histopathological toxicity were observed. The compound doesn't show genotoxicity in micronucleus assay. CONCLUSIONS ACS-AZ10 has potent antitumor activity in vivo along with low toxicity.

Abstract
CONTEXT The genus Xylopia L. (Annonaceae) includes aromatic plants that have both nutritional and medicinal uses. Essential oils of Xylopia species have antitumour effects. However, the efficacy of the essential oil from the fruit of Xylopia langsdorffiana St. Hil & Tul. (EOX) has not been examined. OBJECTIVE EOX was evaluated to determine its chemical composition, antitumour activity and toxicity. MATERIALS AND METHODS EOX was obtained from fresh fruits of X. langsdorffiana subjected to hydrodistillation, and gas chromatography-mass spectrometry was used to characterize the chemical composition of EOX. The toxicity of EOX was evaluated using haemolysis, acute toxicity and micronucleus assays. The in vitro antitumour activity of EOX was investigated using the sulforhodamine B assay. The sarcoma 180 murine tumour model was used to evaluate the in vivo antitumour activity and toxicity of EOX (50 and 100 mg/kg) after 7 d of treatment. RESULTS The major components of EOX were α-pinene (34.57%) and limonene (31.75%). The HC50 (concentration producing 50% haemolysis) was 293.6 μg/ml. EOX showed greater selectivity for the leukaemia cell line K562, with total growth inhibition (TGI) (concentration producing TGI) of 1.8 μg/ml, and for multidrug-resistant ovarian tumour cell line NCI/ADR-RES (TGI of 45.4 μg/ml). The LD50 was approximately 351.09 mg/kg. At doses of 50 and 100 mg/kg, EOX inhibited the in vivo growth of sarcoma 180 by 38.67 and 54.32%, respectively. EOX displayed minor hepatic alterations characteristic of acute hepatitis and induced no genotoxicity. CONCLUSION EOX showed in vitro and in vivo antitumour activity and low toxicity, which warrants further pharmacological studies.

Abstract
Recent research has attempted to direct superantigens towards tumors by means of tumor-targeted superantigen (TTS) strategy. In this study, we explored the antitumor property of TTS by fusing the third loop of transforming growth factor α (TGFαL3) to staphylococcal enterotoxin type B (SEB) and investigated the possibility of the therapeutic application of TGFαL3-SEB as a novel antitumor candidate in mice bearing breast cancer. Treatment was performed through intratumoral and intravenous injection of TGFαL3-SEB. Tumor size/volume, long-term survival, and cytokine secretion were assessed. In addition, the toxicity of each treatment on liver and kidneys was examined. Our results indicated that the relative tumor volume significantly increased in the mice receiving intratumoral TGFaL3-SEB (p < 0.05). Surprisingly, 5 out of the 14 mice were cleared from the tumor thoroughly in 10-25 days after intratumoral administration of TGFaL3-SEB. Quantification of cytokines clearly showed that the mice receiving intratumoral SEB significantly secreted higher interferon γ (IFN-γ) and tumor necrosis factor α (TNF-α) compared with the other groups (p < 0.05). The antitumor effect was followed by inhibition of cell proliferation (Ki-67) and micro vascularization (CD31). The highest and lowest levels of tumor necrosis were observed in the intratumoral administration of TGFαL3-SEB (85 %) and PBS (14 %), respectively. Intratumoral injection of TGFαL3-SEB increased the lifespan of the mice so 37.5 % of them could survive for more than 6 months (p < 0.05). Overall, our findings indicated that intratumoral administration of TGFαL3-SEB effectively inhibited the growth of breast tumors through induction of necrosis and suppressing proliferation and angiogenesis without systemic toxicity.

Abstract
Compounds isolated from essential oils play an important role in the prevention and treatment of cancer. Monoterpenes are natural products, and the principal constituents of many essential oils. The aim of this study was to investigate the cytotoxic potential of p-menthane derivatives. Additionally, analogues of perillyl alcohol, a monoterpene with known anticancer activity, were evaluated to identify the molecular characteristics which contribute to their cytotoxicity, which was tested against OVCAR-8, HCT-116, and SF-295 human tumor cell lines, using the MTT assay. The results of this study showed that (−)-perillaldehyde 8,9-epoxide exhibited the highest percentage inhibition of cell proliferation (GI = 96.32%–99.89%). Perillyl alcohol exhibited high cytotoxic activity (90.92%–95.82%), while (+)-limonene 1,2-epoxide (GI = 58.48%–93.10%), (−)-perillaldehyde (GI = 59.28%–83.03%), and (−)-8-hydroxycarvotanacetone (GI = 61.59%–94.01%) showed intermediate activity. All of the compounds tested were less cytotoxic than perillyl alcohol, except (−)-perillaldehyde 8,9-epoxide (IC50 = 1.75–1.03 µL/mg). In general, replacement of C-C double bonds by epoxide groups in addition to the aldehyde group increases cytotoxicity. Furthermore, stereochemistry seems to play an important role in cytotoxicity. We have demonstrated the cytotoxic influence of chemical substituents on the p-menthane structure, and analogues of perillyl alcohol.

Abstract
Many studies of the scientific literature discuss the anticancer activity of diterpenes inhibiting the Akt/IKK/NF-κB pro-survival signaling cascade, mainly by the activation of serine/threonine phosphatase PP2A. The aim of this work was to evaluate and compare the anticancer potential of three atisane, three kaurane and three trachylobane diterpenes extracted from the roots of Xylopia langsdorffiana. Thus, we investigated the reactivity (H-LGAP parameter), HOMO atmosphere favorable to neutralize the radical reactivity, and the docking of compounds with PP2A. With all approaches, this theoretical study showed that atisane diterpenes have favorable characteristics for antitumor activity, like electron donating ability and greater hydrophilic interactions with the enzyme, by inhibition of Akt/IKK/NF-κB, and activation of PP2A.

Abstract
The aim of this work was to predict the anticancer potential of 3 atisane, and 3 trachylobane diterpene compounds extracted from the roots of Xylopia langsdorffiana. The prediction of anticancer activity as expressed against PC-3 tumor cells was made using a PLS model built with 26 diterpenes in the training set. Significant statistical measures were obtained. The six investigated diterpenes were applied to the model and their activities against PC-3 cells were calculated. All the diterpenes were active, with atisane diterpenes showing the higher pIC50 values. In human prostate carcinoma PC-3 cells, the apoptosis mechanism is related to an inhibition of IKK/NF-κB. Antioxidant potential implies a greater electronic molecular atmosphere (increased donor electron capacity), which can reduce radical reactivity, and facilitate post donation charge accommodation. Molecular surfaces indicated a much greater electronic cloud over atisane diterpenes.
