Attenuation of CFA-induced chronic inflammation by a bicyclic monoterpene fenchone targeting inducible nitric oxide, prostaglandins, C-reactive protein and urea.

Fenchone, found in certain plants, has strong anti-inflammatory properties. In a rat model, it reduced pro-inflammatory markers and improved symptoms of chronic joint inflammation, suggesting therapeutic potential for inflammatory disorders.

Anti-inflammatory compounds from the rhizome of Acorus calamus var. angustatus Besser and their mechanism.

Seven compounds were isolated from the rhizome of a medicinal plant. They showed anti-inflammatory activity by increasing GSH-PX and SOD levels and decreasing MDA, TNF-α, IL-1β, and IL-6 levels. Compound 4 had the strongest anti-inflammatory effect and may inhibit Beclin-1-dependent autophagy.

The Aqueous Extract of Brassica oleracea L. Exerts Phytotoxicity by Modulating H(2)O(2) and O(2)(-) Levels, Antioxidant Enzyme Activity and Phytohormone Levels.

Researchers demonstrated that extract can inhibit the growth of L.varruderale Kit. The extract reduced levels of harmful compounds in roots, increased antioxidant activity in shoots, and increased phytohormone content in seedlings, leading to weed suppression.

Effect of Plant Extracts Combinations on TNF-α, IL-6 and IL-10 Levels in Serum of Rats Exposed to Acute and Chronic Stress.

This study examines the effects of combined plant extracts rich in flavonoids on cytokine levels in stressed rats. The extracts, Antistress I and Antistress II, showed potential in reducing pro-inflammatory cytokines (TNF-α and IL-6) and increasing anti-inflammatory cytokine (IL-10) levels. The combinations were more effective than individual extracts.

Exploring the Biomedical Applications of Biosynthesized Silver Nanoparticles Using Perilla frutescens Flavonoid Extract: Antibacterial, Antioxidant, and Cell Toxicity Properties against Colon Cancer Cells.

Biomimetic synthesis of silver nanoparticles (AgNPs) using a flavonoid extract as a reducer and capper. PFFE-AgNPs showed cytotoxic effects against cancer cells, inhibition of bacteria, and antioxidant activity. Promising potential for biomedical applications, but further research needed for safety and efficacy.
