Abstract
This work investigated the biochemical disturbances and histological alteration in Psammomys obesus animal model fed different high calorie diets (HCDs) during three months. Four diets were used: a low-calorie natural diet, Chenopodiaceae halophyte plant used as control (LCD), a high standard carbohydrate diet rich in protein, HCD 0, a high carbohydrate diet rich in two concentrations of fat, HCD 1 and HCD 2. All animals having received HCDs developed dyslipidemia after one month of experiment with distinction of different sub-groups developing or not obesity and diabetes. HCDs induced a remarkable increasing in blood cholesterol, LDL-cholesterol and triglyceride levels indicating a fast induction of dyslipidemia and a significant increase of aminotransaminases activities revealing a pronounced hepatotoxicity. Animal developing diabetes showed a severe hepatic injury, a degeneration of the adipose tissue and a significant reduction of retinal thickness. P. obesus seems to be an excellent animal model to investigate nutritional metabolic diseases.

Abstract
The use of medicinal plants has gained renewed wide popularity in Africa, Asia, and most parts of the world because of the decreasing efficacy of synthetic drugs. Thus, natural products serve as a potent source of alternative remedy. Tetrapleura tetraptera is a medicinal plant with cultural and traditional significance in West Africa. In addition to the plant being commonly used as a spice in the preparation of traditional spicy food for postpartum care it is also widely used to constitute herbal concoctions and decoctions for treatment of diseases. This review aimed to provide an up-to-date information on the ethnomedicinal uses, pharmacological activities and phytoconstituents of T. tetraptera. Preclinical studies regarding the plant's toxicity profile were also reviewed. For this updated review, literature search was done on PubMed, Science Direct, Wiley, and Google Scholar databases using the relevant keywords. The review used a total of 106 papers that met the inclusion criteria from January 1989 - February 2022 and summarised the bioactivities that have been reported for the rich phytoconstituents of T. tetraptera studied using various chemical methods. Considering the huge report, the review focused on the antimicrobial and antiinflammatory activities of the plant extracts and isolated compounds. Aridan, aridanin and several bioactive compounds of T. tetraptera have shown pharmacological activities though their mechanisms of action are yet to be fully understood. This study also highlighted the influence of plant parts and extraction solvents on its biological activities. It also presented data on the toxicological profile of the plant extracts using different models. From cultural uses to modern pharmacological research the bioactive compounds of T. tetraptera have proved effective in infectious disease management. We hope that this paper provided a robust summary of the biological activities and toxicological profile of T. tetraptera, thus calling for more research into the pharmacological and pharmacokinetic activities of natural products to help combat the growing threat of drug resistance and provide guidelines for their ethnomedicinal uses.

Cytotoxicity, acute and sub-chronic toxicities of the fruit extract of Tetrapleura tetraptera (Schumm. & Thonn.) Taub. (Fabaceae). BMC Complement Med Ther 2022; 22:178. [PMID: 35787267 PMCID: PMC9252075 DOI: 10.1186/s12906-022-03659-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2022] [Accepted: 06/29/2022] [Indexed: 11/10/2022] Open
Abstract
Background Tetrapleura tetraptera is a medicinal spice traditionally used to treat cancer, diabetes, and several other ailments. This study analyzed the cytotoxicity of the dichloromethane methanol extract of T. tetraptera fruits (TTF) and its constituents. The toxicity profile of the TTF extract was also evaluated in rats. Methods The Cytotoxicity of this extract was evaluated using the resazurin reduction assay (RRA). Acute and sub-chronic toxicity studies were performed according to the protocol described by the Organisation for Economic Cooperation, and Development (OECD). Hematological, serum, and urine biochemical parameters, as well as histological sections of the liver and kidney, were also evaluated based on standard methods. Results The TTF extract, compound 5, and the reference drug doxorubicin were active in all 9 tested cancer cell lines. The recorded IC50 ranged from 18.32 μM (against B16-F1 murine melanoma cells) to 36.18 μM (against SKMel-505 BRAF wildtype melanoma cells) for TTF, from 10.02 μM (towards MaMel-80a BRAF-V600E homozygous mutant melanoma cells) to 31.73 μM (against SKMel-28 BRAF-V600E homozygous mutant melanoma cells) for compound 5, and from 0.22 μM (against B16-F1 cells) to 9.39 μM (against SKMel-505 cells) for doxorubicin. The study of acute toxicity test showed that the lethal dose (LD50) of this extract was greater than 5000 mg/kg body weight. In the sub-chronic toxicity studies, variations were observed in some biochemical parameters, especially at higher doses. Conclusion TTF and its most active compound (5) are found to be potential cytotoxic agents, meanwhile, TTF was safe when given a single oral dose of 5000 mg/kg. However, caution is necessary in case of prolonged oral administration due to potential alterations of renal function at high doses (> 1000 mg/kg).

Molecules 2022; 27:molecules27144430. [PMID: 35889305 PMCID: PMC9320383 DOI: 10.3390/molecules27144430] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2022] [Revised: 06/28/2022] [Accepted: 06/29/2022] [Indexed: 02/01/2023] Open
Abstract
Moringa oleifera leaf polyphenols (Mopp) were encapsulated with phytosomes to enhance their efficacy on 4T1 cancer cell lines. The Mopp were extracted via microwave-assisted extraction. Moringa oleifera polyphenol-loaded phytosomes (MoP) were prepared with the nanoprecipitation method and characterized using the dynamic light scattering and dialysis membrane techniques. The in vitro cytotoxic and antiproliferative activity were investigated with the (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazole) MTT assay. Acute toxicity was assessed using Swiss albino mice. An MoP particle size of 296 ± 0.29 nm, −40.1 ± 1.19 mV zeta potential, and polydispersity index of 0.106 ± 0.002 were obtained. The total phenolic content was 50.81 ± 0.02 mg GAE/g, while encapsulation efficiency was 90.32 ± 0.11%. The drug release profiles demonstrated biphasic and prolonged subsequent sustained release. In vitro assays indicated MoP had a low cytotoxicity effect of 98.84 ± 0.53 μg/mL, doxorubicin was 68.35 ± 3.508, and Mopp was 212.9 ± 1.30 μg/mL. Moreover, MoP exhibited the highest antiproliferative effect on 4T1 cancer cells with an inhibitory concentration of 7.73 ± 2.87 μg/mL and selectivity index > 3. The results indicated a significant difference (p ≤ 0.001) in MoP when compared to Mopp and doxorubicin. The in vivo investigation showed the safety of MoP at a dose below 2000 mg/kg. The present findings suggest that MoP may serve as an effective and promising formulation for breast cancer drug delivery and therapy.

Abstract
The present study was carried out to assess the oral safety, proinflammatory and stress response effect of Terminalia catappa aqueous leaf extract (TCA) in male Wistar rats. The acute and sub-acute oral toxicity of TCA was assessed using guidelines 423 and 407 of the Organisation for Economic Co-operation and Development (OECD), respectively. Signs of clinical toxicity, morbidity and mortality were observed. The biochemical, haematological, proinflammatory, stress response and histopathological indices were assessed. In the acute toxicity study, no sign of clinical toxicity, morbidity, and mortality was observed for TCA treatment, up to 5000 mg/kg bwt. However, in the sub-acute toxicity study, repeated daily TCA treatment significantly (p<0.05) altered the body weight gain, plasma alkaline phosphatase activity and albumin concentration. There were no obvious morphological and macroscopic alterations in the organs investigated. TCA appear not to elicit any proinflammatory, stress, systemic and organ toxic effect when utilised at the reported dose and time frame.

JOURNAL OF ETHNOPHARMACOLOGY 2021; 273:113870. [PMID: 33484907 DOI: 10.1016/j.jep.2021.113870] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/05/2020] [Revised: 12/23/2020] [Accepted: 01/18/2021] [Indexed: 06/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The seed of Avocado (Persea americana, Lauraceae), non-edible part of the fruit is used as health product. It has been reported as traditional female contraceptive and sterilizer in Peru and some Asian countries and in Nigeria as cardio-protective agent. The present study focused on the effect of hydro-methanolic seed extract of Persea americana on female hormones and toxicity profile using animal models. MATERIALS AND METHODS The serum follicle stimulating hormone (FSH) and progesterone (PROG) concentrations in mature non-pregnant female rats were assayed using hormonal kits. The toxicity profile was assessed using Lorke's acute toxicity model, haemato-biochemical evaluation and histopathological studies of reproductive related organs. Parameters were measured on day-30, 60 and 90. Presence of biomarker flavonoid compounds were confirmed using High Performance Liquid Chromatography. RESULTS The extract at 20, 100 and 500 mg kg -1 altered FSH and PROG hormone profile of the treated groups. The extract initially, dose-dependently decreased FSH level in day-30 (6.95, 3.97, 2.08 IU/L respectively) compared to untreated group before a significant increase was observed for day 60 and 90. Progesterone increased dose-dependently in the treated groups throughout the 90-day treatment duration. This may be Indicating cumulative effect on the hormone. No deleterious or toxicity effect was noticed. CONCLUSIONS The extract of Persea americana seed affects female hormone activity. This may find application in various hormonal management procedures, maternal and reproductive health and fertility control/help health facilities. However, it should be used with caution in women intending to conceive.

Abstract
Candida albicans is the most common species isolated from nosocomial bloodstream infections. Due to limited therapeutic arsenal and increase of drug resistance, there is an urgent need for new antifungals. Therefore, the antifungal activity against C. albicans and in vivo toxicity of a 1,3,4-oxadiazole compound (LMM6) was evaluated. This compound was selected by in silico approach based on chemical similarity. LMM6 was highly effective against several clinical C. albicans isolates, with minimum inhibitory concentration values ranging from 8 to 32 µg/mL. This compound also showed synergic effect with amphotericin B and caspofungin. In addition, quantitative assay showed that LMM6 exhibited a fungicidal profile and a promising anti-biofilm activity, pointing to its therapeutic potential. The evaluation of acute toxicity indicated that LMM6 is safe for preclinical trials. No mortality and no alterations in the investigated parameters were observed. In addition, no substantial alteration was found in Hippocratic screening, biochemical or hematological analyzes. LMM6 (5 mg/kg twice a day) was able to reduce both spleen and kidneys fungal burden and further, promoted the suppresses of inflammatory cytokines, resulting in infection control. These preclinical findings support future application of LMM6 as potential antifungal in the treatment of invasive candidiasis.

Abstract
Macaranga barteri is a plant used in traditional medicine to treat many illnesses. Previous studies showed the efficacy of the aqueous extract of leaf of this plant (AEMb) in the treatment of gastric ulcer within the dose range of 125-500 mg/kg body weight (b.w.). This study aims at evaluating the safety of AEMb on anthropometric and haematological parameters in wistar rats. Seventy rats were divided into seven groups of ten rats each, including five males and five females. The control group was repeatedly administered by gavage with distilled water at 1 ml/100 g for 28 days while test groups 2, 3, 4 and 5, were repeatedly gavaged with AEMb at the doses of 125, 250, 500 and 1000 mg/kg b.w. respectively. As for satellites (groups 6 and 7), they received daily and respectively distilled water at 1 ml/100 g b.w. and AEMb at the dose of 1000 mg/kg b.w. The results showed that AEMb caused no significant changes in the behaviour of rats and the weight of the organs removed (kidneys, liver, spleen, and heart) and their relative weights at the end of the 28 days of treatment. However, the body weight and the amount of food consumed by animals treated with AEMb at the doses of 250, 500 and 1000 mg/kg b.w. increased significantly (p < 0.05) from the third week compared to control group. Haematological analysis revealed a non-significant increase (p > 0.05) in leukocyte lineage and platelet level in female rats at the studied doses. However, a significant (p < 0.05) increase in platelet level was recorded in male rats at 1000 mg/kg b.w. A significant (p < 0.05) increase in erythrocyte and hemoglobin levels at the doses of 250, 500 and 1000 mg/kg b.w. in treated animals was also revealed. In conclusion, repeated administration of AEMb over 28 days to rats was safe on leucocyte lineage and most of erythrocyte indices at doses ranging from 125 to 1000 mg/kg b.w. Nevertheless, the use of this extract caused a transient increase of erythrocyte, hemoglobin and platelet levels 2 weeks after the end of AEMb administration, but these effects disappeared. So, the subacute oral administration of AEMb revealed few potential toxic effects overall.

Abstract
Background Lauric acid (LA), a common constituent of coconut oil, is used as food additives and supplements in various formulations. Despite various potential pharmacological properties, no scientific evidence on its dose-related toxicity and safety is available till date. Objective The current study was conducted to evaluate acute oral toxicity of LA on normal rats. Methods The study was conducted in accordance with the Organization for Economic Co-operation and Development guidelines (OECD 423) with slight modifications. LA was administered orally to female Sprague Dawley (SD) rats (n = 6/group) at a single dose of 300 and 2,000 mg/kg body weight, respectively, while normal control received vehicle only. Animals from all the three groups were monitored for any behavioural and toxicological changes and mortality for two weeks. Food and fluid consumption, body weight was monitored on daily basis. At the end (on day 15th) of the experimental period, blood was collected for haematological and biochemical analysis. Further, all the animals were euthanized, and internal organs were harvested for histopathological investigation using four different stainings; haematoxylin and eosin, Masson trichrome, Periodic Acid Schiff and Picro Sirius Red for gross pathology through microscopical observation. Results The study results showed no LA treatment-related mortality and morbidity at two different dosages. Daily food and water consumption, body weight, relative organ weight, haematological, and biochemical analysis were observed to be normal with no severe alterations to the internal tissues. Conclusion The current finding suggests that single oral administration of LA, even up to 2,000 mg/kg body weight, did not exhibit any signs of toxicity in SD rats; thus, it was safe to be used on disease models in animals.

Total glucosides of paeony (TGP) extracted from Radix Paeoniae Alba exerts neuroprotective effects in MPTP-induced experimental parkinsonism by regulating the cAMP/PKA/CREB signaling pathway. JOURNAL OF ETHNOPHARMACOLOGY 2019; 245:112182. [PMID: 31445131 DOI: 10.1016/j.jep.2019.112182] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/25/2019] [Revised: 08/08/2019] [Accepted: 08/21/2019] [Indexed: 06/10/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The totally-amounted glucosides of paeony (TGP), which are made up of paeoniflorin, albiflorin, oxypaeoniflorin as well as benzoylpaeoniflorin, constitute the Baishao' actively-working component extracted from Radix Paeonia alba employed in conventional oriental medicine aiming to treat cerebrovascular disorders, such as Parkinson's disease. However, its pharmacologic mechanism is not clear. AIM OF THE STUDY The initial investigation was made on TGP's neuroprotective effects on PD of the mouse model based on 1-methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine (MPTP) as well as the identification of potential involvement of a molecular signaling pathway. MATERIALS AND METHODS The evaluation of the behavioral damage as well as neurotoxicity in mice was made through MPTP. Spontaneous motor activity test, as well as a test of Rota-rod on mice was employed for the measurement of bradykinesia symptom. Additionally, liquid chromatography-electrospray ionization tandem mass spectrometry (LC-ESI-MS-MS) works as the determiner of the main monoamine neurotransmitters dopamine (DA) along with its metabolites 3, 4-dihydroxyphenylacetic acid (DOPAC) as well as homovanillic acid (HVA) based on mouse hippocampus connected with the anti-Parkinson's disease like effect of TGP. Besides, the measurement of the effects of TGP treatment on the expressions level of TH, DAT, a-synuclein, p-CREBS133 as well as apoptosis influence was made with the help of western-blot assay with apoptosis-related markers such as Bax and Bcl-2. RESULTS The results showed that TGP treatment lessened the behavior-based loss shown "in the spontaneous motor activity as well as the potential of falling to rotarod test". In addition, we found that pretreatment with TGP markedly improved motor coordination, striatal dopamine and its metabolite levels. Furthermore, pretreatment of TGP conducted the protection for dopaminergic neurons with the prevented MPTP-induced reductions within the tyrosine hydroxylase (TH), substantia nigra dopaminergic transporter (DAT), as well as increasing α-synuclein protein levels with transformed dopamine catabolism as well as inhibited dopamine turnover. Besides, TGP treatment helped reversed apoptosis signaling molecules Bcl-2/Bax' reduction; meanwhile improving p-CREBS133 the factor of growth signaling in the substantia nigra' decrease. CONCLUSION These results suggested that TGP can enhance dopaminergic neuron's cell survival in the SNpc in virtue of the activated cAMP/PKA/CREB factor of growth on inhibiting the pathway of second messenger apoptosis as well. In conclusion, the current findings indicate TGP is expected to be a new cure for PD.
