Abstract
Glioblastomas are tumors that present a high mortality rate. Artemether (ART) is a lactone with antitumor properties, demonstrating low bioavailability and water solubility. In the present study, we developed lipid-core nanocapsules (LNC) containing pequi oil (Caryocar brasiliense Cambess) as the oily core for ART-loaded LNCs (LNCART) and evaluated their effect on human glioblastoma cells (U-87 MG). LNCs were developed by interfacial deposition of a preformed polymer, followed by physicochemical characterization. LNCART revealed a diameter of 0.216 µm, polydispersity index of 0.161, zeta potential of -12.0 mV, and a pH of 5.53. Furthermore, mitochondrial viability, proliferation, total antioxidant status, and antioxidant enzyme activity were evaluated. ART reduced cell viability after 24 h and proliferation after 48 h of treatment at concentrations equal to or above 40 µg . mL-1. LNCART, at 1.25 µg . mL-1, reduced these parameters after 24 h of treatment. Furthermore, superoxide dismutase (SOD) activity was elevated, while glutathione reductase (GR) activity was reduced. These findings suggest that ART loaded into LNC may be a promising alternative to improve its pharmacological action and possible application as a therapeutic agent for glioblastoma.

Ther Adv Drug Saf 2021; 12:20420986211027101. [PMID: 34349977 PMCID: PMC8287264 DOI: 10.1177/20420986211027101] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2019] [Accepted: 06/04/2021] [Indexed: 12/05/2022] Open
Abstract
AIM Fansidar (FAN) is widely used as an antimalarial drug, but it may cause hepatoxicity, nephrotoxicity, and neurotoxicity. Hence, the study examines the cytoprotection of selenium (Se) and zinc (Zn) tablets against FAN induced toxicity. METHOD Group I was given distilled water. Groups II, III, IV, and V received 50 mg/kg FAN by gavage. Group III was co-treated with a 50 mg/kg Se tablet. Group IV was co-treated with a 50 mg/kg Zn tablet. Group V was co-treated with a 50 mg/kg Se tablet + 50 mg/kg Zn tablet. The exposure lasted for 7 days (sub-acute exposure). RESULT FAN causes cytotoxicity through significant (p < 0.05) alteration of antioxidant molecules and hepatic enzymes. It also significantly (p < 0.05) induces renal, hepatocyte, and purkinje cell damage, but no visible lesion on testicular cells. The FAN induced cytotoxicity was significantly (p < 0.05) reversed on treatment with both single and combined antioxidant tablets. CONCLUSION Our study supports the view that antioxidant micronutrient (Se and Zn) tablets may be a useful modulator in alleviating FAN induced oxidative stress and cytotoxicity in male rats. PLAIN LANGUAGE SUMMARY Combined selenium and zinc capsules: better therapy against cytotoxicity Fansidar was approved by United States' Food and Drug Administration as an anti-malarial drug to treat acute and complicated malaria fever among patients in West Africa; however, its usage elicits toxicity to several organs of the body. It was elucidated that the combination of selenium and zinc capsules promotes organ wellness on co-treatment with Fansidar.

Abstract
OBJECTIVE Antimalarials are globally used against plasmodium infections, however, information on the safety of new antimalarial combination therapies on the gastric mucosa is scarce. The aim of this study was to investigate the effects of Artesunate-Amodiaquine and Artemether-Lumefantrine on ulcer induction. Malondialdehyde (MDA), reduced glutathione (GSH) and major histological changes in male Wistar rats following ulcer induction using Indomethacin were investigated. Gastric ulcers were in four groups; Group I was administered Artesunate, group II received Artesunate-Amodiaquine, group III received Artemether-Lumefantrine, and group IV was a positive control (normal saline). Group V was the negative control consisting of healthy rats. RESULTS Antimalarial combination therapies were associated with a high gastric ulcer index than a single antimalarial agent, Artesunate. In addition, levels of MDA were significantly higher in the combination of therapies while levels of GSH were lower in comparison to Artesunate and the negative control. Microscopically, antimalarial combination therapies were associated with severe inflammation and tissue damage than Artesunate in the gastric mucosa showing that antimalarial combination therapies exert their toxic effects through oxidative stress mechanisms, and this leads to cellular damage. Findings in this study demonstrate a need to revisit information on the pharmacodynamics of major circulating antimalarial agents in developing countries.

Abstract
In the last decade it has become clear that, similarly to nucleated cells, enucleated red blood cells (RBCs) are susceptible to programmed apoptotic cell death. Erythrocytic apoptosis seems to play a role in physiological clearance of aged RBCs, but it may also be implicated in anemia of different etiological sources including drug therapy and infectious diseases. In malaria, severe anemia is a common complication leading to death of children and pregnant women living in malaria-endemic regions of Africa. The pathogenesis of malarial anemia is multifactorial and involves both ineffective production of RBCs by the bone marrow and premature elimination of non-parasitized RBCs, phenomena potentially associated with apoptosis. In the present overview, we discuss evidences associating erythrocytic apoptosis with the pathogenesis of severe malarial anemia, as well as with regulation of parasite clearance in malaria. Efforts to understand the role of erythrocytic apoptosis in malarial anemia can help to identify potential targets for therapeutic intervention based on apoptotic pathways and consequently, mitigate the harmful impact of malaria in global public health.

Abstract
BACKGROUND Unsweetened natural cocoa powder (UNCP), prepared after removal of the cocoa butter, is a common beverage in Ghana. It possesses antimalarial prophylactic property and has a beneficial effect on blood components. AIM The aim of this study was to determine whether regular dietary supplement of UNCP mitigates high-dose (HD) artemether-lumefantrine (A-L)-induced hematological disorders and to determine the effect on nitric oxide (NO) levels. MATERIALS AND METHODS Adult male guinea pigs (300 g - 350 g) were randomly divided into 5 groups of 6 guinea pigs each. Among the 5 groups, 3 groups were treated with UNCP (300, 900, and 1500 mg/kg body weight) for 14 days. A-L (75 mg/kg) was administered from the 12th to 14th day. One of the remaining 2 groups received distilled water only, i.e., vehicle control group (VCG) while the other received 75 mg/kg A-L only, i.e., negative control group (NCG). Blood samples from all groups were obtained by cardiac puncture (day 15) followed by hematological and NO analysis. RESULTS A-L reduced white blood cells (WBC) by 31.87%, lymphocyte count by 45.99%, hemoglobin by 11.72%, hematocrit by 18.56%, and platelet count by 33.08% in the NCG. Administration of various doses of UNCP increased WBC and lymphocyte count (P > 0.05) compared to the NCG. UNCP and A-L combination caused an increase in NO levels when compared to the VCG. CONCLUSION Regular consumption of UNCP by guinea pigs increases plasma NO and restores some hematological disorders induced by a 3-day HD A-L administration.

Abstract
In the current study, we evaluated the endocrine disruption effect and oxidative stress implication of therapeutic dose of artemether-lumefantrine combination therapy on the ovary and uterus of rats. In this respect, female rats were divided into four groups: animals were per orally treated with tween 80 (control), artemether (4 mg kg-1 body weight), lumefantrine (24 mg kg-1 body weight) and artemether-lumefantrine (artemether, 4 mg kg-1 body weight and lumefantrine, 24 mg kg-1 body weight). We found that therapeutic doses of the drugs did not change the levels of ovarian hydrogen peroxide (H2O2) and malondialdehyde (MDA), but increased uterine levels of H2O2 and MDA and reduced ovarian and uterine levels of reduced glutathione. In addition, whilst ovarian glutathione peroxidase (GPx) activity reduced in the lumefantrine monotherapy group, uterine GPx increased in the artemether monotherapy as well as the artemether-lumefantrine groups. Furthermore, the drugs reduced ovarian and uterine glutathione- S-transferase and uterine superoxide dismutase activities. The drugs reduced oestrogen level, whereas follicle-stimulating hormone was reduced by lumefantrine and artemether-lumefantrine therapies. Additionally, artemether and lumefantrine monotherapies significantly increased prolactin and progesterone levels compared with the control ( p < 0.05). The results suggest that in the absence of malarial parasite infection, the drugs induced oxidative stress in the ovary and uterus and disrupt hormonal balance in the rats.

Abstract
Artemisinin is an antimalarial drug previously reported to induce neurotoxicity and embryotoxicity in animal models. This study investigated the erythrocytes and reproductive toxicity potentials of artemisinin in female rats. Animals were randomly divided into four study groups of eight rats each. The control group (group I) received corn oil, the vehicle, while groups II-IV were orally exposed to 7, 35 and 70 mg kg(-1) day(-1) of artemisinin, respectively, by gastric intubation for 7 consecutive days. Subsequently, we evaluated the impact of artemisinin on the endocrine environment and selected markers of oxidative damage and antioxidant status of the erythrocytes, ovary and uterus. Artemisinin significantly increased hydrogen peroxide (H2O2) and malondialdehyde (MDA) levels and decreased catalase, glutathione peroxidase and superoxide dismutase activities in erythrocytes and uterus of rats compared with control group (p < 0.05). However, artemisinin did not alter ovarian MDA, H2O2, glutathione levels and catalase activity, while ovarian and uterine histological assessment revealed absence of visible lesions. Moreover, artemisinin significantly decreased follicle-stimulating hormone and increased progesterone levels compared with control (p < 0.05). Thus, these data suggest that in the absence of malarial parasite infection, artemisinin induced hormonal imbalance and oxidative damage in the erythrocytes and uterus but spared the ovary of rats.

Abstract
The main objective of this study is to investigate the cytotoxic, genotoxic and antioxidant properties of zingiberene (ZBN) in an in vitro rat brain cell culture study. The cytotoxic effect was determined against the rat neuron and N2a neuroblastoma (N2a-NB) cell lines using the 3,(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, while the antioxidant activity was assessed using the total antioxidant capacity (TAC) and total oxidative stress (TOS) assays. The effects on DNA damage were also evaluated in this study by the single cell gel electrophoresis assay. The results indicated that ZBN has an anti-proliferative activity suppressing the proliferation of N2a-NB cells at concentrations over 50 mg L(-1) and neuron cells at concentrations over 150 mg L(-1). In addition, ZBN treatments at higher doses (≤50 mg L(-1)) led to increases of TOS levels in N2a-NB cell cultures. However 25 mg L(-1) of ZBN treatment caused increases of TAC levels in cultured neuron and N2a-NB cell cultures while ZBN at doses of 10-400 mg L(-1) did not increase the number of total damage score in both cell lines. This study clearly indicates that ZBN has a significant potential to be used as a natural anticancer agent in cultured N2a-NBs.

Abstract
Sesquiterpenes have attracted much interest with respect to their protective effect against oxidative damage that may be the cause of many diseases including several neurodegenerative disorders and cancer. Our previous unpublished work suggested that cyclosativene (CSV), a tetracyclic sesquiterpene, has antioxidant and anticarcinogenic features. However, little is known about the effects of CSV on oxidative stress induced neurotoxicity. We used hydrogen peroxide (H2O2) exposure for 6 h to model oxidative stress. Therefore, this experimental design allowed us to explore the neuroprotective potential of CSV in H2O2-induced toxicity in new-born rat cerebral cortex cell cultures for the first time. For this aim, MTT and lactate dehydrogenase release assays were carried out to evaluate cytotoxicity. Total antioxidant capacity (TAC) and total oxidative stress (TOS) parameters were used to evaluate oxidative changes. In addition to determining of 8-hydroxy-2-deoxyguanosine (8-OH-dG) levels, the single cell gel electrophoresis (or Comet assay) was also performed for measuring the resistance of neuronal DNA to H2O2-induced challenge. Our results showed that survival and TAC levels of the cells decreased, while TOS, 8-OH-dG levels and the mean values of the total scores of cells showing DNA damage (Comet assay) increased in the H2O2 alone treated cultures. But pre-treatment of CSV suppressed the cytotoxicity, genotoxicity and oxidative stress which were increased by H2O2. On the basis of these observations, it is suggested that CSV as a natural product with an antioxidant capacity in mitigating oxidative injuries in the field of neurodegenerative disorders.
