Background: Development of synovial hypertrophy, articular tissue inflammation and tenderness in joints is the characteristic feature of rheumatoid arthritis. Drugs that are derived from natural sources which target inflammation with reduced side-effects receive much attention. Hence, the present study was designed to investigate the anti-arthritic effects of α-bisabolol, a natural chamomile essential oil and also an anti-inflammatory molecule on the rat model of collagen-induced arthritis (CIA). Methods: Animal model of CIA was established and orally administered with α-bisabolol (100 mg/kg) or vehicle and the pathological and inflammatory parameters were evaluated. Result: The results of the present findings indicate that α-bisabolol treatment ameliorates CIA-induced inflammation via inhibiting the proteases and inflammatory mediators suggesting that α-bisabolol may be a potential candidate against arthritis inflammations.

Inflammatory Action

In a double-blind cross-over study the analgesic and anti-inflammatory action of ibuprofen 1600 mg/day in cases of rheumatoid arthritis has been compared with aspirin 4 g/day, metiazinic acid 1 .5 g/day and a placebo, lactose. Each compound was administered in identical capsules and in a totally randomised order to all patients studied. Assessment of the articular index, grip strength, knee score, erythrocyte sedimentation rate and subjective improvement was made before and after one week's treatment with each drug. In the doses used in this trial, the analgesic and anti-inflammatory activity of metiazinic acid in rheumatoid arthritis, was found to be approximately equipotent to that of aspirin, while ibuprofen seemed to be slightly more potent and to cause fewer side-effects.

Inflammatory Action

Background: Pentacyclic triterpenoids are a biologically active class of phytoconstituents with diverse pharmacological activity including anti-inflammatory action. Objective: In the current study, we isolated 3-Acetylmyricadiol, a pentacyclic triterpenoid, from the ethyl acetate bark-extract of Myrica esculenta and evaluated it for anti-inflammatory potential. Methods: The ethyl acetate bark-extract of the M. esculenta was subjected to column chromatography to isolate 3-Acetylmyricadiol. MTT assay was performed to check cell viability. The production of proinflammatory mediators like Nitric oxide, IL-6, TNF-α was observed after administration of 5, 10, 20 μM of 3-Acetylmyricadiol in LPS-activated Raw 246.7 macrophages by the reported methods. Results: MTT assay indicated more than 90% cell viability up to 20 μM of 3-Acetylmyricadiol. The administration of 3-Acetylmyricadiol inhibited the production of Nitric oxide, IL-6, TNF-α in a dose-dependent manner significantly in comparison to LPS treated cells. The maximum effect was observed at 20 μM of 3-Acetylmyricadiol which resulted in 52.37, 63.10, 55.37 % inhibition of Nitric oxide, IL-6, TNF-α respectively. Conclusion: Our study demonstrated the anti-inflammatory action of 3-Acetylmyricadiol and can serve as a potential candidate in the development of the clinically efficient anti-inflammatory molecule.

Experimental Expression

Rheumatoid arthritis, caused by abnormalities in the autoimmune system, affects about 1% of the population. Rheumatoid arthritis does not yet have a proper treatment, and current treatment has various side effects. Therefore, there is a need for a therapeutic agent that can effectively treat rheumatoid arthritis without side effects. Recently, research on pharmaceutical drugs based on peptides has been actively conducted to reduce negative effects. Because peptide drugs are bio-friendly and bio-specific, they are characterized by no side effects. Truncated-IK (tIK) protein, a fragment of IK protein, has anti-inflammatory effects, including anti-rheumatoid arthritis activity. This study focused on the fact that tIK protein phosphorylates the interleukin 10 receptor. Through homology modeling with interleukin 10, short tIK epitopes were proposed to find the essential region of the sequence for anti-inflammatory activity. TH17 differentiation experiments were also performed with the proposed epitope. A peptide composed of 18 amino acids with an anti-inflammatory effect was named tIK-18mer. Additionally, a tIK 9-mer and a 14-mer were also found. The procedure for the experimental expression of the proposed tIK series (9-mer, 14-mer, and 18-mer) using bacterial strain is discussed.

Fenbufen, a new butanoic acid derivative with anti-inflammatory properties, was evaluated in an open-label study. It was found that fenbufen was an effective anti-inflammatory agent with tolerable and acceptable potential side-effects. Its advantages appeared to be its long clinical half-life and relatively mild toxicity and/or allergic response.
