Objective: Knema attenuata (Myristicaceae), popularly known as “wild nutmeg,” is an endemic tree species from Western Ghats, which has been used in folk medicine. Conventionally, the stem bark of K. attenuata is used for treating inflammatory conditions without any scientific information available for the same. The present study was undertaken to evaluate the anti-inflammatory activity of the ethanolic stem bark extract (ESBE) of K. attenuata using in vivo and in vitro screening models. Methods: The ethanolic extract of stem bark was prepared by soxhlation, and its cytotoxicity in RAW 264.7 cell line was assessed using MTT assay method. In vivo anti-inflammatory effect of extract was estimated in rats using carrageenan-induced paw edema model and cotton pellet-induced granuloma model. The in vitro anti-inflammatory activity of the extract was evaluated by cyclooxygenase and lipoxygenase inhibition assay, estimation of myeloperoxidase activity, and determination of cellular nitrite levels in lipopolysaccharide-stimulated RAW 264.7 macrophage cells. Results: Toxic symptoms were not observed for the ESBE. The extract demonstrated significant anti-inflammatory activity in both in vivo and in vitro models. The anti-inflammatory action exhibited by the extract was a result of the inhibition of leukocyte migration and nitric oxide pathway and partially by inhibition of mediators such as prostaglandins and leukotrienes. Conclusion: Findings from the study provide the evidence for the popular use of stem bark extract of K. attenuata as a potential anti-inflammatory agent.

Bioprospecting has contributed to the work of pharmaceutical chemists in the development and commercial disposal of new drugs. Currently, the pharmaceutical industry has emphasized drugs produced from bioactive compounds extracted from natural sources, based on popular medicine discussed in the literature, such as secondary metabolites isolated from the stem bark and seeds of the Amburana cearensis, rich in coumarin derivatives, flavonoids, and phenolic acids and is popularly used in the treatment of respiratory diseases and with anti-inflammatory and antioxidant bioactivity. This review is a study of the structure/activity and structure/property (SAR/SPA) relationship with the physicochemical properties calculated by the algorithms of the MarvinSketch software for the secondary metabolites of A. cearensis, as well as their correlation with in silico test values the SwissADME and admetSAR 2.0 servers and in vitro and in vivo models of the dataset from the PreADMET, GUSAR Online and PASS Online servers. The results showed that substances derived from coumarin, flavonoids, and phenolic acids have attributes of good permeability and low efflux, which favor their oral bioavailability, since phenolic heterosides, amburoside analogs, and biflavonoids are effective in local action as subcutaneous application, constituting promising antimicrobial, anti-inflammatory and antioxidant therapeutic actions in their proper administration routes.

The major end-products of dietary fiber fermentation by gut microbiota are the short-chain fatty acids (SCFAs) acetate, propionate, and butyrate, which have been shown to modulate host metabolism via effects on metabolic pathways at different tissue sites. Several studies showed the inhibitory effects of sodium propionate (SP) on nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) pathway. We carried out an in vitro model of inflammation on the J774-A1 cell line, by stimulation with lipopolysaccharide (LPS) and H2O2, followed by the pre-treatment with SP at 0.1, 1 mM and 10 mM. To evaluate the effect on acute inflammation and superoxide anion-induced pain, we performed a model of carrageenan (CAR)-induced rat paw inflammation and intraplantar injection of KO2 where rats received SP orally (10, 30, and 100 mg/kg). SP decreased in concentration-dependent-manner the expression of cicloxigenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) following LPS stimulation. SP was able to enhance anti-oxidant enzyme production such as manganese superoxide dismutase (MnSOD) and heme oxygenase-1 (HO-1) following H2O2 stimulation. In in vivo models, SP (30 and 100 mg/kg) reduced paw inflammation and tissue damage after CAR and KO2 injection. Our results demonstrated the anti-inflammatory and anti-oxidant properties of SP; therefore, we propose that SP may be an effective strategy for the treatment of inflammatory diseases.

Insight Into

Anthocyanin is a type of flavonoid pigment widely present in fruits and vegetables. It can not only be used as natural pigment, but also has a variety of health functions, for instance, anti-oxidant, anti-inflammatory, anti-tumor, and neuroprotective activities. Persistent proinflammatory status is a major factor in the development, progression, and complications of chronic diseases. Not surprisingly, there are thus many food ingredients that can potentially affect inflammation related diseases and many studies have shown that anthocyanins play an important role in inflammatory pathways. In this paper, the inflammation related diseases (such as, obesity, diabetes, cardiovascular disease, and cancer) of anthocyanins are introduced, and the anti-inflammatory effect of anthocyanins is emphatically introduced. Moreover, the anti-inflammatory mechanism of anthocyanins is elaborated from the aspects of NF-κB, toll like receptor, MAPKs, NO, and ROS and the main efficacy of anthocyanins in inflammation and related diseases is determined. In conclusion, this review aims to get a clear insight into the role of anthocyanins in inflammation related diseases.
