Several Ajuga species are used in Romanian folk medicine for their antioxidant, antimicrobial and anti-inflammatory properties, to treat pain, fever or arthritis. Still, the active compounds responsible for these effects and their mechanism of action are scarcely known. This research was designed to investigate the phytochemical profile (e.g. iridoids, polyphenolic compounds, phytosterols), as well as the biological potential (antioxidant, antibacterial, antifungal, anti-inflammatory properties) of two selected Ajuga species collected from different regions of Romanian spontaneous flora. The main compounds identified in A. reptans aerial parts extracts were 8-O-acetylharpagide, isoquercitrin and β-sitosterol, whilst in A. genevensis were 8-O-acetylharpagide, luteolin and campesterol. The extracts were screened for their antioxidant potential using different methods (DPPH, TEAC, EPR) and the results showed a good activity, in accordance with the polyphenol content (18–26 mg GAE/g dw). The antifungal activity on the tested strains was good. The determination of few parameters linked with the inflammatory mechanism allowed the assessment of in vivo anti-inflammatory potential. Ajuga reptans and A. genevensis ethanol extracts had anti-inflammatory activity through lowering the oxidative stress, phagocytosis, PMN and total leukocytes. The best anti-oxidative and anti-inflammatory activity was observed for the Ajuga reptans 100 mg dw/mL extract when compared with diclofenac, thus the dose could be correlated with the pharmacological effect. These findings provide substantial evidence that both selected Ajuga species have the potential to be valued as sources of phytochemicals in effective anti-inflammatory herbal preparations.

Melampyrum barbatum Waldst. & Kit. ex Willd. (Scrophulariaceae) has been used in traditional medicine for the treatment of rheumatic complaints and different skin diseases. In the course of our study the anti-inflammatory activity of the aerial parts of M. barbatum was evaluated. A MeOH extract was prepared and consecutively partitioned with CHCl3, EtOAc and n-BuOH. The fractions were assayed in in vivo carrageenan-induced rat paw oedema model. The intraperitoneally administered n-BuOH phase exerted marked inhibitory effect (33.6 %, p < 0.01). Multistep chromatographic separation afforded mussaenoside and aucubine from n-BuOH fraction. Moreover, 8-epiloganin, loganic acid and mussaenoside were obtained from EtOAc fraction and apigenin, luteolin, benzoic acid and galactitol from CHCl3 fraction. These data validate the ethnomedicinal use of M. barbatum for the treatment of inflammatory diseases and reveal that iridoids and flavonoids could be responsible for the anti-inflammatory effect of this species.

The air-dried aerial parts of Phlomis russeliana (Sims) Lag. Ex Benth. was extracted by methanol and fractionated by n-hexane, dichloromethane, and ethyl acetate, respectively. The wound healing properties of P. russeliana extract gel was evaluated using the in vivo excisional wound model using Balb-c mice. Initially, the P. russeliana methanol extract showed LOX inhibitory activity at IC50 = 23.2 µg/mL, whereas the DPPH• assay showed IC50 = 0.89 mg/mL, and the ABTS• assay showed IC50 = 0.99 mg/mL, respectively. In addition, a remarkable anti-inflammatory activity was observed in the cell culture assay. Thereafter, activity-guided fractionation was performed by LOX enzyme inhibition assays, and the structures of the two most active fractions were revealed by both GC–FID and GC/MS analyses, simultaneously. Phytol and 1-heptadecanoic acid were characterized as the active constituents. Moreover, the P. russeliana extract gel formulation was applied for in vivo tests, where the new gel formulation supported the in vitro anti-inflammatory activity findings. As a conclusion, this experimental results support the wound healing evidence based on the ethnobotanical application of Phlomis species with further potential.

Caryocar coriaceum fruits, found in Brazilian Cerrado and Caatinga, are commonly used as food and in folk medicine, as anti-inflammatory, bactericide, fungicide, leishmanicide, and nematicide. Due to the biological potential of this plant, this study focuses on the evaluation of antifungal and antileishmanial activities, including anticholinesterase and antioxidant tests, correlating with total phenols and flavonoids content. Peel extracts contain higher yield of phenols and flavonoids as analyzed by spectrophotometric methods. HPLC analysis of flavonoids revealed that isoquercitrin is the main flavonoid in both parts of the fruit, and peel extract showed the best antioxidant activity. In the inhibition of the acetylcholinesterase assay, both extracts demonstrate action comparable to physostigmine. The antimicrobial activity of extracts was evaluated against strains of Malassezia sp. and Microsporum canis, using the broth microdilution technique, in which the extracts showed similar MIC and MFC. The extracts present antileishmanial activity and low toxicity on murine macrophages and erythrocytes. Therefore, these results suggest a potential for the application of C. coriaceum fruit’s ethanol extracts in the treatment against dermatophyte fungi and leishmaniasis, probably due to the presence of active flavonoids. Further in vivo studies are recommended aiming at the development of possible new pharmaceutical compounds.

Satureja cuneifolia Ten. (wild savoury) belongs to the Lamiaceae family and is used to produce essential oil and aromatic water. This plant is also used as a condiment and herbal tea due to its stimulating, tonic and carminative effects. The in vitro antioxidant, anti-urease, anticholinesterase and cytotoxic activities of the different extracts from the plant’s aerial parts were examined. Besides, the in vivo anti-inflammatory activities of the fraction and direct methanol extracts were determined comparatively. In the current study, fraction methanol extract exhibited the strongest ABTS (52.34 mM trolox/mg extract) radical scavenging and ferric reduction (17.22 mM Fe2+/mg extract) activity. It was also found that the fraction methanol extract had stronger anti-urease (12.52%) and anticholinesterase (69.02%) activity than other extracts.  The XTT results showed that fraction methanol extract had the most cytotoxic activity on MCF-7 cell lines (39.92%).  According to the results of in vivo anti-inflammatory activity, it was found that both fraction and direct methanol extracts exhibited close and significant anti-inflammatory activity. The fact that methanol extracts have significant biological activity suggests that these may be used as a natural source in the future.

Introduction: Rumex spp. have been used in folk medicine either as food or as medicine for the treatment of several diseases including constipation, fever, inflammation, bacterial and fungal infections. This study aimed to evaluate the anti-inflammatory and antimicrobial activities of the successive extracts of the aerial parts of Rumex pictus Forssk. growing in Egypt, and to identify the chemical constituents in the bioactive extract. Methods: Ether, chloroformic, and 70% methanolic extracts of the aerial parts of R. pictus were assayed for their in vivo anti-inflammatory activity using carrageenan-induced rat hind paw edema method. These extracts were also tested for their in vitro antibacterial and antifungal activities using disc diffusion method. Results: The 70% methanolic extract of R. pictus exhibited significant anti-inflammatory, antibacterial, and anti-candida activities. Thus, fractionation of the bioactive extract was performed which led to the isolation of three anthraquinones, as well as, seven flavonoids. Conclusion: Rumex pictus possesses anti-inflammatory and antimicrobial activities which reinforce its use in ethnomedicine.

Monoclonal IgG antibodies to CD44 (anti-CD44) are anti-inflammatory in numerous murine autoimmune models but the mechanisms are poorly understood. Anti-CD44 anti-inflammatory activity shows complete therapeutic concordance with intravenous immunoglobulin (IVIg) in treating autoimmune disease models, making anti-CD44 a potential IVIg alternative. In murine immune thrombocytopenia (ITP), there is currently no mechanistic explanation for anti-CD44 activity although anti-CD44 ameliorates disease similarly to IVIg. Here we demonstrate a novel anti-inflammatory mechanism of anti-CD44 that explains disease amelioration by anti-CD44 in murine ITP. Macrophages treated with anti-CD44 in vitro had dramatically suppressed phagocytosis through FcγRs in two separate systems of IgG-opsonized platelets and erythrocytes. Phagocytosis inhibition by anti-CD44 was mediated by blockade of the FcγR IgG binding site without changing surface FcγR expression. Anti-CD44 of different subclasses revealed that FcγR blockade was specific to receptors that could be engaged by the respective anti-CD44 subclass, and Fc-deactivated anti-CD44 variants lost all FcγR-inhibiting activity. In vivo, anti-CD44 functioned analogously in the murine passive ITP model and protected mice from ITP when thrombocytopenia was induced through an FcγR that could be engaged by the CD44 antibody's subclass. Consistent with FcγR blockade, Fc-deactivated variants of anti-CD44 were completely unable to ameliorate ITP. Together, anti-CD44 inhibits macrophage FcγR function and ameliorates ITP consistent with an FcγR blockade mechanism. Anti-CD44 is a potential IVIg alternative and may be of particular benefit in ITP due to the significant role of FcγRs in human ITP pathophysiology.

Abstract Albizia myriophylla has been used in Thai folk medicine for treating inflammation-related diseases. The wood of this medicinal plant is traditionally used as a single herbal drug in the form of an aqueous decoction and as a component in several Thai herbal formulations for the remedy of fever, sore throat, and aphthous ulcers. This study aimed to evaluate in vivo the anti-inflammatory potential and possible mechanism of action of the standardized wood extract of A. myriophylla as well as to investigate the anti-inflammatory activity and physicochemical properties of the developed herbal gel formulation containing standardized wood extract of A. myriophylla. Results of quantitative HPLC analysis demonstrated that the standardized wood extract of A. myriophylla contained 22.95 mg/g of 8-methoxy-7,3′,4′-trihydroxyflavone, a bioactive marker compound of A. myriophylla. The standardized wood extract of A. myriophylla (1% w/v) exhibited remarkable inhibition (54.4 – 80.3%) in the croton oil model of topical inflammation at all assessment times, comparable to standard indomethacin (55.3 – 63.6%). Real-time quantitative reverse transcription-polymerase chain reaction was performed to clarify the anti-inflammatory mechanism of standardized wood extract of A. myriophylla, and the result showed that this standardized extract decreased lipopolysaccharide-induced nitric oxide synthase mRNA levels in a dose-dependent manner. The developed herbal gel containing standardized wood extract of A. myriophylla (1% w/w) had good physicochemical characteristics and exhibited potent inhibition (51.4 – 77.8%) of inflammation in a rat ear edema model at all assessment times, comparable to indomethacin gel (33.3 – 40.5%). The notable anti-inflammatory activity of standardized wood extract of A. myriophylla and its developed herbal gel formulation indicates their potential application as natural anti-inflammatory agents.

Arthrophytum scoparium is plant commonly used in folk medicine in Algeria to treat numerous human diseases especially infectious, Rheumatism, diabetes and cancer. However, its anti-inflammatory activity and the underlying mechanisms have not been studied systematically. The present study aims to assess both the in vitro and in vivo anti-inflammatory potential and antioxidant activity of the plant. Results showed that A. scoparium chloroform extract (ChE) contains the largest amount of phenolic and flavonoid compounds. In-vitro bioassay consisted of investigating the effect of the plant extracts against protein denaturation (BSA and egg albumin). In-vivo anti-inflammatory activity was evaluated by measuring the percentage inhibition of carrageenan-induced rat paw edema after oral administration of the extracts. Results showed that inhibition of protein denaturation was maximum in case of A. scoparium crude extract (CrE) with dose dependant manner. Similarly in the in-vivo study, carrageenan induced inflammation was significantly antagonized by CrE with inhibition of 87.02% at 400 mg/kg. CrE extracts showed the highest scavenger effect against hydroxyl and hydrogen peroxide. The CrE showed potent anti-inflammatory activity in both the conditions in vivo and in vitro. In conclusion different A. scoparium extracts scavenged reactive oxygen species efficiently; it may be due to the presence of its flavonoids and polyphenols. These results support the traditional use of this plant. Keywords: Arthrophytum scoparium, polyphenols, anti-inflammatory activity, radical scavenging activity.
