Background: Pandiaka angustifolia Valh Hepper (Amaranthaceae) whole plant is used in folk Burkinabe’s medicine to treat ailments with an inflammatory component. Previous studies revealed the antioxidant capacity, xanthine oxidase, and lipoxygenase inhibitory activities of the plant, but to the best of our knowledge, its anti-inflammatory activities were not reported before. Therefore, this study was designed to evaluate the anti-inflammatory and analgesic activity of P. Angustifolia hexane and aqueous extracts using in vitro enzymatic methods and in vivo methods and verify the best anti-inflammatory extract implication in KATP pathways. Experiments: acute toxicity of the plant was conducted under OECD 423 guidelines. Phospholipase and cyclooxygenases were pro-inflammatory enzymes used to evaluate in vitro anti-inflammatory effects of plant extracts while carrageenan induced edema method was used to evaluate the anti-edematous activity and acetic acid inducing writhing method to evaluate the non-morphine analgesic effect of herbal mixture. ATP sensitive K+ channel assay was performed in vivo using the glibenclamide as ATP-sensitive potassium channel (KATP) blocker. Results: enzymatic inhibition assays revealed that both hexane and aqueous extracts of P. angustifolia were good inhibitors against sPLA2 activity with IC50 values of 14.23 ± 0. 72 µg/mL and 11.56 ± 0.11 µg/mL, respectively. Aqueous extract presented the best inhibition for COX-1 (IC50 = 24.76 ±0. 51 µg/mL) while hexane extract concentration that inhibit 50% of COX-2 was lesser than those of aqueous extract. P. angustifolia aqueous extract orally administrated to NMRI mice caused no death at the dose of 3000 mg/kg b.w indicating that the plant toxicity is low. While hexane extract was unable to reduce Carrageenan-induced edema, ethanolic extract were significantly active when extract was orally administrated. Non-morphine analgesic activity evaluation revealed that ethanolic extract was more efficient on writhing reduction than hexane extract. Nociception effect of the plant is linked with its effects on K+ ATP sensitive channels. Conclusion: Results indicate that the anti-inflammatory potential of P. angustifolia may be due to its polar phytoconstituents and observed pharmacological activities provide the scientific basis for the medicinal use of the plant in the treatment of ailment associated with inflammation.

The Impact

Sutherlandia frutescens (L.) R. Br (Lessertia frutescens) is a medicinal plant traditionally used in southern Africa. It has been used for patients suffering from numerous types of cancer, infectious diseases, and various inflammatory conditions. This study was designed to determine the impact of S. frutescens on the inflammatory response and anti-microbial activities on cell and/or animal models. Aqueous and ethanolic extracts of S. frutescens were made and verified using HPLC. These extracts were used to treat murine macrophages (e.g., RAW 264.7 cells and primary macrophages isolated from mice) to evaluate the impact of S. frutescens on in vitro inflammatory responses. This study found that the aqueous extract and a polysaccharide-enriched fraction from the aqueous extract exhibited an immuno-stimulatory activity on murine macrophages. Treatment with aqueous extract or polysaccharides increased the production of reactive oxygen species (ROS), nitric oxide (NO), and inflammatory cytokines/chemokines via activating the toll-like receptor 4 signaling pathway. On the other hand, the ethanolic extract of S. frutescens dose-dependently decreased the production of ROS, NO, inducible nitric oxide synthase (iNOS), and various inflammatory cytokines and chemokines in murine macrophages co-stimulated with lipopolysaccharide (LPS) and interferon gamma (IFNy). Follow up experiments demonstrated that the anti-inflammatory activity of the ethanolic extract was mediated via reductions in the activation of NF-kB, extracellular-signal-regulated kinase 1/2 (ERK1/2), and signal transducers and activators of transcription 1 (STAT1). RNA sequencing provided more evidences to support the anti-inflammatory activity of the ethanolic extract of S. frutescens. To our surprise, chlorophylls isolated from S. frutescens had a greater effect on the anti-inflammatory of S. frutescens than that of unique compounds (i.e., sutherlandiosides and sutherlandins). To investigate the impact of oral consumption of S. frutescens on in vivo inflammatory responses and anti-microbial activities, mice were fed with AIN-93G based diet with/without containing ground S. frutescens powder or were gavaged with S. frutescens extracts followed by challenge with E. coli or LPS. These experiments found that oral consumption of S. frutescens had limited or no impact on the in vivo inflammatory responses and anti-microbial activities. Overall, this study provide a better understanding on the beneficial therapeutic properties of S. frutescens using in vitro models, however these studies in a laboratory mouse model suggest that consumption of S. frutescens had only a modest impact on host anti-microbial and inflammatory responses to a gram-negative microbial challenge whether intact microbes or bacterial endotoxin (i.e., LPS) was used.

Anastatica hierochuntica L. ( A. hierochuntica), a folk medicinal plant, was evaluated for mutagenic potential via in vitro and in vivo assays. The in vitro assay was conducted according to modified Ames test, while the in vivo study was performed according to Organisation for Economic Co-operation and Development guideline for mammalian erythrocyte micronucleus assay. Four groups ( n= 5 males and 5 females per group) Sprague Dawley rats were randomly chosen as the negative control, positive control (received a single intramuscular injection of cyclophosphamide 50 mg/kg), 1000 and, 2000 mg/kg A. hierochuntica aqueous extracts. All groups except the positive control were treated orally for three days. Findings of the in vitro assay showed mutagenic potential of AHAE at 0.04 and 0.2 mg/ml. However, no mutagenic effect was demonstrated in the in vivo study up to 2000 mg/kg. No significant reduction in the polychromatic and normochromatic erythrocytes ratio was noted in any of the groups. Meanwhile, high micronucleated polychromatic erythrocytes frequency was seen in cyclophosphamide-treated group only. These findings could perhaps be due to insufficient dosage of A. hierochuntica aqueous extracts to cause genetic damage on the bone marrow target cells. Further acute and chronic in vivo toxicity studies may be required to draw pertinent conclusion on the safety aspect of A. hierochuntica aqueous extracts consumption. Impact statement In this paper, we report on the mutagenicity evaluation of Anastatica hierochuntica aqueous extract. This is a significant research in view of the popularity of this herb consumption by the people across the globe despite of limited scientific evidence on its toxicity potential. This study is intended to encourage more extensive related research in order to provide sufficient evidence and guidance for determining its safe dosage.

Background. Different pharmacological properties, such as antioxidant, antiproliferative, and anti-inflammatory properties, have been described among natural products. We previously described that the Bougainvillea xbuttiana (Variety Orange) ethanolic extract (BxbO) has an anti-inflammatory effect; however, this action is not fully understood. In this study, the action of the BxbO extract on the secretion of inflammatory mediators in two experimental models, in vitro and in vivo, after LPS challenge was evaluated. Methods. Peritoneal macrophages were obtained from female BALB/c mice and LPS-challenged with or without the BxbO extract. For the evaluation of mediators, the supernatants at 0, 12, 24, 36, and 48 hours were collected. For in vivo estimation, groups of female BALB/c mice were first intraperitoneously injected with different amounts of LPS and later administered the oral BxbO extract (v.o.) for 144 hours. To understand the mechanism of action, sera obtained from mice were collected at 0, 2, 4, 8, 12, and 24 hours after LPS challenge (with or without BxbO) for the detection of mediators. Results. The results showed that, in both peritoneal macrophages and sera of mice treated with the BxbO extract 1 hour before or together with LPS challenge, proinflammatory cytokines and nitric oxide release were unquestionably repressed. In contrast, in both systems studied here, the IL-10 levels were elevated to 5 to 9 times. At lethal doses of LPS, the BxbO extract treatment was found to protect animals from death. Conclusions. The results revealed that the inhibitory, protective, and benign effects of the BxbO extract were due to its capacity to balance the secretion of mediators.

Inflammatory diseases have affected a large proportion of the population worldwide, and inflammation is a major risk factor for several dangerous disease pathologies. The increasing incidence and impact of inflammatory diseases have prompted research into pharmacological strategies to deal with them. Chromolaena odorata is traditionally used as an anti-inflammatory, antipyretic, antioxidant, analgesic, and as a wound-healing agent. Therefore, this review aimed to obtain a comprehensive review of the anti-inflammatory activity of Chromolaena odorata. This review provides evidence in the literature for the anti-inflammatory and analgesic activity of Chromolaena odorata, from 2010 to 2021. Three bibliographic databases were used as primary sources of information (PubMed, ScienceDirect, and Google Scholar). The keywords in this research were "Anti-inflammatory", "Analgesic" and "Chromolaena odorata". A total of 7 studies were included in this review according to the required criteria, 3 of which were in vitro studies and 4 in vivo studies.Pharmacological studies reported that Chromolaena odorata was proven to have anti-inflammatory activity by inhibiting NO, NF-κβ, p38 MAPK, IL-1β, TNF-α, suppressed leukocyte cell migration, reduced of edema and Chromolaena odorata also was shown analgesic activity through significantly reduced stomach writhing and reduction pain sensation in rats. This review explains the potential importance of Chromolaena odorata as a natural anti-inflammatory and analgesic.

Abstract Numerous compounds derived from natural sources such as microbes, plants, and insects have proven to be safe, efficacious, and cost-effective therapeutics for human diseases. This study examined the bioactivities of propolis, a structural sealant and antibacterial/antifungal agent produced by honey bees. Chinese propolis was extracted in methanol or hexane. Propolis significantly reduced the numbers of viable cancer cells when applied as a methanol extract (IC50 values in μg/mL for the indicated cell line: MDA-MB-231, 74.12; LoVo, 74.12; HepG2, 77.74; MCF7, 95.10; A549, 114.84) or a hexane extract (MDA-MB-231, 52.11; LoVo, 45.9; HepG2, 52.11; MCF7, 78.01; A549, 67.90). Hexane extract also induced apoptosis of HepG2 cells according to activated caspase-3/7 expression assays (17.6 ± 2.9% at 150 μg/mL and 89.2 ± 1.9% at 300 μg/mL vs 3.4 ± 0.4% in vehicle control), suppressed the growth of Candida albicans and multiple multidrug-resistant and nonresistant Gram-positive bacteria, and inhibited croton oil-induced skin inflammation when applied as topical treatment. GC-MS identified hexadecanoic acid methyl ester as a major constituent (33.6%). Propolis hexane extract has potential anticancer, antimicrobial, and anti-inflammatory activities.

Background and Aims: Nitric oxide (NO) has an essential role in inflammation and has been related to pathogenesis and the progress of numerous inflammatory-based diseases, including some cancers. Peganum harmala (P. harmala) is a medicinal plant used for the treatment of numerous diseases such as several infections. Also, anti-inflammatory effects of P. harmala extracts and its derivatives (harmaline and harmine) by suppressing myeloperoxidase, NO, and other mediators have been demonstrated in vivo. In this study, the effect of P. harmala seeds aqueous extract on NO production in U937 monocytic cells and peritoneal macrophages has been evaluated in vitro. Materials and Methods: U937 and mice peritoneal macrophages were cultured in Roswell Park Memorial institute-1640 with 10% fetal calf serum. Then, the cells at the logarithmic growth phase were incubated with different concentrations of aqueous extract of P. harmala seeds (0.1-1 mg/ml) for 24 hours. Next, NO production was assessed by the Griess method in the culture medium. Results: P. harmala seeds aqueous extract did not significantly affect lipopolysaccharide-induced NO production in U937 cells and peritoneal macrophages after 24 hours incubation time compared with untreated control cells. Conclusion: These results suggest that the anti-inflammatory effects of P. harmala may be mediated through NO-independent mechanism(s). However, further studies are warranted to define the P. harmala aqueous extract impact on NO expression in other related normal and cancerous cells.

Maydis Stigma (MS) is an herb traditionally used in many parts of the world. Previous studies have reported that MS plays a role in several biological activities, including antidiabetic and anticancer activities. However, the effects of a MS ethanolic extract (MSE) on the anti-inflammatory cellular mechanism remain unclear. Here, we investigated the anti-inflammatory properties of MSE and its molecular mechanism both in vitro and in vivo. The effects of MSE on the production of inflammatory mediators, cytokines, and related proteins and the identification of target genes were determined using LPS-stimulated macrophages. We also determined the analgesic and anti-inflammatory effects of MSE by examining acetic acid-induced writhing responses and xylene-induced ear edema in mice. Our results indicated that MSE markedly decreased iNOS and COX-2 levels without causing cytotoxicity and suppressed the secretion of NO in LPS-stimulated macrophages. MSE also inhibited the production of proinflammatory cytokines, such as TNF-[Formula: see text], IL-6, and IL-1[Formula: see text], and induced the expression of HO-1. Moreover, MSE treatment significantly reduced the LPS-stimulated activation of MAPK, NF-[Formula: see text]B, and AP-1. Furthermore, MSE exerted an analgesic effect on the acetic acid-induced abdominal writhing response test and an anti-inflammatory effect on xylene-induced ear edema in ICR mice. Finally, we investigated the components of MSE using UPLC-ESI-MS and found that it contains the maysin as a marker component. Overall, these observations demonstrate that MSE has anti-inflammatory and antinociceptive effects both in vitro and in vivo, which may provide new scientific evidence for its use as a potential therapeutic agent for the treatment of inflammation.
