: The present work reports synthesis and screening of fifteen 2,5-disubstituted-4-thiazolidinones with different substitutions of varied arylidene groups at imino. The structures of the compounds were confirmed by spectral characterization. The compounds were subjected to in vivo anti-inflammatory and in vitro antioxidant activities. The derivatives possessed remarkable activities quite close to standard drugs used. Unlike conventional non-selective NSAIDs, the synthesized compounds did not contain any acidic group, thereby ensuring a complete cure from ulcers. To further substantiate the claim for safer derivatives, the active compounds were docked against the cyclooxygenase (COX)-2 enzyme. It was found that 4-fluorophenylimino substituent at 2- position and 3-nitro moiety on a 5-benzylidene nucleus of the 4-thiazolidinone derivative fitted in the COX-2 binding pocket. The compounds exhibited remarkable activity in scavenging free radicals, as depicted by the DPPH assay method. The structure-activity relationship was also established in the present work with respect to the nature and position of the substituents. The active compounds were evaluated for drug-like nature under Lipinski’s rule of five, and the toxicity behaviour of active compounds was predicted using ADMETlab software. The compounds have the potential to target degenerative disorders associated with inflammation and the generation of free radicals.

The presence of various bioactive components makes it necessary to analyse plants for their potential to act as a source of useful treatments and cures for many inflammatory, infectious and pathogenic diseases. This study was carried out to determine phytochemicals and in-vitro antioxidant activities of the leaf extracts of Acalypha godseffiana. The leaves of A. godseffiana were collected, dried, pulverized and extracted separately with methanol and water using maceration method. The extract was concentrated in vacuo with rotary evaporator at 40oC. The extracts were subjected to quantitative phytochemical analysis and different anti-oxidant analytical procedures like FRAP, DPPH etc to determine the radical scavenging capabilities. The results of phytochemical analysis estimated the quantities and revealed the presence of alkaloids, flavonoids, tannins, saponins and terpenoids which varied in both extracts. The methanol and aqueous extracts exhibited antioxidant activities with relatively high IC50 (IC50 = 3.67 ìg/ml and 4.42ìg/ml respectively) which accounted for a low free radical-scavenging activity when compared with the reference antioxidant, vitamin C (IC50 = 1.51ìg/ml). The results of the study indicates that A. godseffiana leaf extracts contain secondary metabolites and possesses antioxidant properties.

This study aimed to isolate, prepare and identify the main flavonoids from a standardized Smilax glabra flavonoids extract (SGF) using preparative HPLC, MS, 1H NMR and 13C NMR, determine the contents of these flavonoids using UPLC, then compare their pharmacological activities in vitro. We obtained six flavonoids from SGF: astilbin (18.10%), neoastilbin (11.04%), isoastilbin (5.03%), neoisoastilbin (4.09%), engeletin (2.58%) and (−)-epicatechin (1.77%). The antioxidant activity of six flavonoids were evaluated by determining the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical and 2,2′-Azinobis (3-ethylbenzothiazoline-6-sulphonic acid) diammonium salt (ABTS+) radical scavenging activity and ferric reducing antioxidant power (FRAP). In addition, the anti-inflammatory activity of six flavonoids were evaluated by determining the production of cytokines (IL-1β, IL-6), nitric oxide (NO) using enzyme linked immunosorbent assay and the NF-κB p65 expression using Western blotting in lipopolysaccharide (LPS)-stimulated RAW264.7 cells. The results showed that (−)-epicatechin, astilbin, neoastilbin, isoastilbin and neoisoastilbin had strong antioxidant activities, not only in DPPH and ABTS+ radicals scavenging capacities, but in FRAP system. Furthermore, all the six flavonoids could significantly inhibit the secretion of IL-1β, IL-6, NO (p < 0.01) and the protein expression of NF-κB p-p65 (p < 0.01) in LPS-stimulated RAW264.7 cells. This study preliminarily verified the antioxidant and anti-inflammatory activities of six flavonoids in S. glabra.

Abstract Oxidative stress is a critical etiologic factor and driver of inflammatory responses, witnessed in chronic and persistent conditions. The current anti-oxidative stress and anti-inflammatory drugs are associated with detrimental effects, high dependence, high costs, inaccessibility, among other drawbacks; therefore, a need for alternatives is imperative. Despite the remarkable potential of medicinal plants, there are scanty empirical studies on their pharmacologic efficacy. The Phytexponent is an alcoholic polyherbal preparation of Allium sativum, Triticum repens, Echinacea purpurea, Viola tricolor and Matricaria chamomilla. In complementary medicine, the Phytexponent is used to boost immunity, to treat inflammatory disorders, oxidative stress, blood pressure, diabetes, stress/depression, among other conditions. However, there is no sufficient scientific data to support these healing claims. Therefore, in the current study evaluated the in vitro anti-inflammatory, antioxidant activities and qualitative phytochemical composition of the Phytexponent. The in vitro anti-inflammatory activities were evaluated using the inhibition of protein denaturation and the human erythrocyte (HRBC) membrane stabilization techniques. Antioxidant activities were evaluated by the 1,1-diphenyl-picryl-1-hydrazyl (DPPH) radical scavenging-, the hydroxyl radical scavenging- and catalase activities. Qualitative phytochemical screening was performed using standard procedures. The results showed a significantly higher percentage inhibition of heat-induced- and hypotonicity induced HRBC hemolysis by the Phytexponent at concentrations of 50 % and 100 %, compared with the percentage inhibitions of etanercept (p<0.05). No significant differences in percentage inhibitions of protein denaturation were observed among concentrations of 12.5 %,25.0 %,50.0 %,100.0 % of the Phytexponent and etanercept (25 mg/ml) (p˃0.05). Furthermore, the Phytexponent demonstrated high antioxidant activities against the DPPH- (IC50=0.00733%) and the hydroxyl- (IC50 = 0.716 %) radicals in vitro.The Phytexponent recorded significantly higher catalase activities at concentrations of 1 % and 0.1 % than those recorded by ascorbic acid at similar concentrations. Qualitative phytochemical screening revealed the presence of phenols, flavonoids, tannins, among other antioxidant associated phytochemicals. The bioactivities of the Phytexponent reported herein, were attributed to the presence of these phytochemicals. Further studies to establish specific mode(s) through which the Phytexponent exerts in vitro anti-inflammatory and antioxidant effects are encouraged. Moreover, in vivo anti-inflammatory and antioxidant activities should be done to determine the replicability of these findings in vivo. Bioassay-guided isolation of compounds responsible for the reported bioactivities herein should be done.

The work presents the results of an investigation into the molecular background of the activity of Cotoneaster fruits, providing a detailed description of their phytochemical composition and some of the mechanisms of their anti-inflammatory and antioxidant effects. GS-FID-MS and UHPLC-PDA-ESI-MS3 methods were applied to identify the potentially health-beneficial constituents of lipophilic and hydrophilic fractions, leading to the identification of fourteen unsaturated fatty acids (with dominant linoleic acid, 375.4–1690.2 mg/100 g dw), three phytosterols (with dominant β-sitosterol, 132.2–463.3 mg/100 g), two triterpenoid acids (10.9–54.5 mg/100 g), and twenty-six polyphenols (26.0–43.5 mg GAE/g dw). The most promising polyphenolic fractions exhibited dose-dependent anti-inflammatory activity in in vitro tests of lipoxygenase (IC50 in the range of 7.7–24.9 μg/U) and hyaluronidase (IC50 in the range of 16.4–29.3 μg/U) inhibition. They were also demonstrated to be a source of effective antioxidants, both in in vitro chemical tests (DPPH, FRAP, and TBARS) and in a biological model, in which at in vivo-relevant levels (1–5 μg/mL) they normalized/enhanced the nonenzymatic antioxidant capacity of human plasma and efficiently protected protein and lipid components of plasma against peroxynitrite-induced oxidative/nitrative damage. Moreover, the investigated extracts did not exhibit cytotoxicity towards human PMBCs. Among the nine Cotoneaster species tested, C. hjelmqvistii, C. zabelii, C. splendens, and C. bullatus possess the highest bioactive potential and might be recommended as dietary and functional food products.

The objectives of the study were to test the biological activities of peppermint and spearmint oils via (i) measuring in vitro anti-inflammatory effects with porcine alveolar macrophages (PAMs), (ii) determining the barrier integrity of IPEC-J2 by analyzing transepithelial electrical resistance (TEER), (iii) testing their antioxidant activities, and (iv) investigating the antimicrobial activity against enterotoxigenic Escherichia coli (ETEC) F18+. Briefly, (i) macrophages were seeded at 106 cells/mL and treated (24 h) with mint oils and lipopolysaccharide (LPS). The treatments were 2 (0 or 1 μg/mL of LPS) × 5 (0, 25, 50, 100, 200 µg/mL of mint oils). The supernatants were collected for TNF-α and IL-1β measurement by ELISA; (ii) IPEC-J2 cells were seeded at 5 × 105 cells/mL and treated with mint oils (0, 25, 50, 100, and 200 μg/mL). TEER (Ωcm2) was measured at 0, 24, 48, and 72 h; (iii) the antioxidant activity was assessed (0, 1, 50, 100, 200, 500, and 600 mg/mL) using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging and reducing power assays; (iv) overnight-grown ETEC F18+ were quantified (CFU/mL) after supplementing with peppermint and spearmint oils (0, 1.44, 2.87, 5.75, 11.50, and 23.00 mg/mL). All data were analyzed using the MIXED procedure. Both mint oils significantly inhibited (p < 0.05) IL-1β and TNF-α secretion from LPS-stimulated PAMs. Mint oil treatments did not affect TEER in IPEC-J2. Spearmint and peppermint oils exhibited (p < 0.05) strong antioxidant activities in DPPH and reducing power assays. Both mint oils also dose-dependently inhibited (p < 0.05) the growth of ETEC F18+ in vitro. The results of the study indicated that both mint oils are great candidate feed additives due to their in vitro anti-inflammatory, antioxidant, and antimicrobial effects. Further research is needed to evaluate their efficacy in vivo.
