Inflammatory Effect

Barringtonia augusta methanol extract (Ba-ME) is a folk medicine found in the wetlands of Thailand that acts through an anti-inflammatory mechanism that is not understood fully. Here, we examine how the methanol extract of Barringtonia augusta (B. augusta) can suppress the activator protein 1 (AP-1) signaling pathway and study the activities of Ba-ME in the lipopolysaccharide (LPS)-treated RAW264.7 macrophage cell line and an LPS-induced peritonitis mouse model. Non-toxic concentrations of Ba-ME downregulated the mRNA expression of cytokines, such as cyclooxygenase and chemokine ligand 12, in LPS-stimulated RAW264.7 cells. Transfection experiments with the AP-1-Luc construct, HEK293T cells, and luciferase assays were used to assess whether Ba-ME suppressed the AP-1 functional activation. A Western blot assay confirmed that C-Jun N-terminal kinase is a direct pharmacological target of Ba-ME action. The anti-inflammatory effect of Ba-ME, which functions by β-activated kinase 1 (TAK1) inhibition, was confirmed by using an overexpression strategy and a cellular thermal shift assay. In vivo experiments in a mouse model of LPS-induced peritonitis showed the anti-inflammatory effect of Ba-ME on LPS-stimulated macrophages and acute inflammatory mouse models. We conclude that Ba-ME is a promising anti-inflammatory drug targeting TAK1 in the AP-1 pathway.

The present work was aimed to identify phytochemicals in C. uredinicola methanol extract from qualitative, TLC and GC-MS method and evaluated for antioxidant, anti-HIV, anti-diabetes, anti-cholinesterase activity in vitro and in silico. The C. uredinicola extract showed flavonoids, tannins, alkaloids, glycosides, phenols, terpenoids, and coumarins presence in qualitative method. From GC-MS analysis, identified seven different phytochemicals and out of seven, four (coumarin, coumarilic acid, hymecromone, alloisoimperatorin) are coumarins. The C. uredinicola extract have shown significant antioxidant activity in DPPH (73) and FRAP (1359) method. The HIV-1 RT (83.81+2.14), gp 120 (80.24+2.31), integrase (79.43+3.14) and protease (77.63+2.14), DPPIV, β-glucosidase and acetyl cholinesterase activity was significantly reduced by the extract. The 2-diphenylmethyleneamino methyl ester had shown significant interaction with oxidant and HIV-1 proteins whereas alloisoimperatorin have interacted with diabetes and cholinesterase proteins followed by hymecromone with high binding energy. These three phytochemicals are non-carcinogens, non-toxic, readily degradable and have drug likeliness properties. The C. uredinicola phytochemicals are responsible for management of diabetes, HIV-1 and Alzheimer. Further in vivo work is needed to justify our research.

In the present study, we investigated the antinociceptive effects of the plant Vigna unguiculata spp dekindtiana using chemical and thermal tests in mice. The peripheral and the central analgesic activities of the methanol extract and its fractions were investigated in-vivo in albino mice using acetic acid induced-writhing test and hot plate models respectively. The result of the central analgesic effect showed that the methanol extract (VUME) at 400 mg/kg produced a significant (p<0.05) delay in reaction time in mice on hot plate compared to the control. Various fractions of the extract showed more potency compared to the crude extract. In acetic writhing model, the extract and the fractions demonstrated dose dependent reduction in writhing reaction induced by acetic acid in mice. The reduction was significant when compared to control which was suggestive of the analgesic effect of the plant. It was also seen that the extract and fractions showed an improved analgesic effect compared to diclofenac used as positive control in this model. Yohimbine (alpha adrenergic receptor antagonist) and cyproheptadine (serotonergic receptor antagonist) reversed the antinociceptic effect of the fractions in the hot plate model demonstrating the possibility of adrenergic and serotonergic involvement in eliciting the analgesic effect. Naloxone on the other hand, caused a reversal only in the butanol fraction meaning that this fraction may contain active principles that may mediate their analgesic effect through the opioid mechanism. In the writhing test, yohimbine abolished the analgesic effect of both hexane and butanol fractions. This may therefore, suggest that the analgesic effect of these fractions may be mediated through adrenergic pathway. In conclusion, the plant V. unguiculata subspecies dekindtiana possesses active principles with potential analgesic activity, establishing the folkloric use of the plant in managing pain.

The objective of the current investigation was performed to assess the hepatoprotective potentials and in vivo antioxidant properties of methanol extract of Tephrosia pumila against thioacetamide induced liver damage in rats. The acute oral toxicity study of methanol extract was determined as per OECD guidelines and the extract was proved to be safe up to the dose of 2000mg/kg. The total duration of the study was 21 days and animals were divided into six groups. Hepatotoxicity was induced in the animals of all groups except normal control by single dose administration of Thioacetamide(100mg/kg) at first day of the study followed by animals were treated daily with standard drug sylimarin and methanol extract of Tephrosia pumila (100mg/kg, 200mg/kg and 400mg/kg) to respective groups for 21 days. Variations in biochemical parameters like alanine transferase (ALT), aspartate transferase (AST), alkaline phosphatase (ALP), total bilirubin, direct bilirubin, albumin, total protein, ions and others parameters like clotting time and weight of the liver were considered to determine beneficial effect of the extract. At the end of the study liver samples were collected and subjected to histopathological evaluation. There were significant variations in the above mentioned biochemical parameters in toxic control animals treated with Thioacetamide alone while in the animals treated with methanol extract and standard drug silymarin, all the parameters were normal possibly due to their beneficial property in protecting the liver against thioacetamide induced hepatotoxicity. The results obtained in the above study suggesting that, the methanol extract of Tephrosia pumila possess significant hepatoprotective activity.

Background: Vernonia amygdalina Del. (Asteraceae) is reported to be traditionally used for the treatment of malaria. Based on folkloric repute of this plant in Ethiopian traditional medicine and crude extract-based ethnopharmacological studies conducted in few countries, this study was undertaken to evaluate the in vivo antimalarial activity of 80% methanol extract and its solvent fractions of the leaves of V. amygdalina in mice infected with Plasmodium berghei. Methods: A 4-day suppressive test was conducted on mice infected with P. berghei to find out antimalarial effect of chloroform, butanol and aqueous fractions obtained from the 80% methanol crude extract. In all the activity tests, mice were randomly assigned in five groups (three tests and two controls) of six animals in each and received respective treatments. Data were analyzed using one way analysis of variance followed by Tukey’s post hoc test for multiple comparisons. Results: Acute oral toxicity test showed that all solvent fractions of the leaves of V. amygdalina revealed neither mortality nor overt signs of toxicity up to 2000 mg/kg. This study indicated that the percentage parasitemia suppression of 80% methanol extract was 32.47% (±2.65), 35.40% (±3.14) and 37.67% (±2.50) at 200, 400 and 600 mg/kg, respectively. All doses of the 80% methanol extract of V. amygdalina prolonged survival time and prevented weight loss and packed cell volume reduction in infected mice. All doses of chloroform and butanol fractions significantly suppressed parasitemia (p < 0.05), increased survival time (p < 0.05) compared to negative control and exhibited a significant reduction in rectal temperature (p < 0.05). All solvent fractions significantly prevented weight loss (p < 0.05) at all tested doses. The 80% methanol extract and chloroform and butanol fractions significantly (p < 0.05) prevented further reduction in rectal temperature of P. berghei-infected mice at all doses. Conclusion: The results of this study indicated that 80% methanol extract and solvent fractions of the leaves of V. amygdalina demonstrated promising antimalarial activity. The study corroborated the folklore use of this plant for the treatment of malaria in ethnomedicine in Ethiopia.

<P>Background: As natural herbs and medicinal plants extracts are widely used as alternative treatments for different parasitic diseases, some have been tested on Cryptosporidium either in vitro or in vivo. This study assessed the prophylactic and therapeutic treatments' effect of Moringa oleifera (M. oleifera) leaves methanol extract on immunosuppressed-Cryptosporidium infected mice. Methods: The evaluation was carried out by Cryptosporidium oocysts count in fecal samples, histopathological changes in the intestinal tissues, determination of IFN-γ level in mice sera and measuring the antioxidant activity in the intestinal tissues. Results: Prophylactic treatment by M. oleifera extract lowered Cryptosporidium oocysts shedding from immunosuppressed-infected mice although there was no complete elimination of the parasite. However, therapeutic treatment induced a significant reduction in Cryptosporidium oocysts counts by 91.8% higher than that of the drug control (nitazoxanide) group (77.2%). Histopathologically, the intestinal tissues from immunosuppressed-Cryptosporidium infected mice showed loss of brush border with severe villous atrophy and extensive necrosis. M. oleifera prophylactic treatment induced a moderate improvement of the pathological changes. However, the villi in M. oleifera therapeutic treated mice retained their normal appearance with minimal inflammatory cells. It was observed that M. oleifera extract induced a significant upregulation of IFN-γ in both prophylactic and therapeutic treated groups compared to that of the infected untreated group. In addition, M. oleifera leaves extract exhibited a significant antioxidant activity by reducing the levels of Nitric Oxide (NO) and Malondialdehyde (MDA) and increasing Superoxide Dismutase (SOD) level in the intestinal tissues compared to those of the infected and drug controls. Conclusion: M. oleifera leaves extract has potent prophylactic and therapeutic activities against infection with Cryptosporidium.</P>
