Safety evaluation and modulatory effects on innate immune system of pyrazoline-derived compounds.

Pyrazolines are compounds that have been studied for their strong biological potential and structure diversity. Several studies demonstrated their biological effectiveness, highlighting their anti-inflammatory potential. This study aimed to evaluate the physicochemical profile, the safety, and the anti-inflammatory effects of four pyrazolines (PH0, PH3, PH4, and PH7).

Tagetes erecta L.: A traditional medicine effective in inflammatory process treatment.

Ethnopharmacological Relevance: Tagetes erecta L. (Asteraceae), popularly known as Aztec Marigold, is used in folk medicine to treat several ailments including inflammatory processes. Despite its historical use, the specific mechanisms through which it may modulate inflammation, particularly its effects on neutrophils and macrophages activation, have not yet been completely investigated.

β-Caryophyllene Inhibits Oxaliplatin-Induced Peripheral Neuropathy in Mice: Role of Cannabinoid Type 2 Receptors, Oxidative Stress and Neuroinflammation.

Peripheral neuropathy is an important adverse effect caused by some chemotherapeutic agents, including oxaliplatin (OXA). OXA-induced peripheral neuropathy (OIPN) is a challenging condition due to diagnostic complexities and a lack of effective treatment. In this study, we investigated the antiallodynic effect of β-caryophyllene (BCP), a cannabinoid type 2 (CB2) receptor agonist, in a mouse model of OIPN.

Neuroinflammation and hypersensitivity evidenced by the acute and 28-day repeated dose toxicity tests of ostrich oil in mice.

The ostrich oil (OO) has been topically used for decades to treat skin diseases. Its oral use has been encouraged through e-commerce advertising several health benefits to OO without scientific evidence on its safety or effectiveness. This study presents the chromatographic profile of a commercially available OO and its acute and 28-day repeated dose in vivo toxicological profiles.

Involvement of a neutrophil-mast cell axis in the effects of Piper malacophyllum (C. PESL) C. DC extract and its isolated compounds in a mouse model of dysmenorrhoea.

The effects of Piper malacophyllum (C. Pesl) C. DC extracts and its isolated compounds were analysed in a mouse model of primary dysmenorrhoea (PD).

Sambucus nigra: A traditional medicine effective in reducing inflammation in mice.

Ethnopharmacological Relevance: Sambucus nigra L. is a plant of European origin and popularly known as elder, elderberry, black elder, European elder, European elderberry, and European black elderberry, being described in pharmacopoeia of several countries. Its flowers and berries have been used in folk medicine to treat feverish conditions, coughing, nasal congestion, and influenza besides its popular use as anti-inflammatory, analgesic, and diuretic agent.

Anti-Inflammatory and Healing Activity of the Hydroalcoholic Fruit Extract of Solanum diploconos (Mart.) Bohs.

Background: (Mart.) Bohs is a native Brazilian plant belonging to the Solanaceae family, popularly known as "tomatinho do mato" and poorly investigated. Herein, we presented for the first time evidence for the anti-inflammatory and wound healing activities of fruit hydroalcoholic extract.

Effect of the metanolic extract from the leaves of Garcinia humilis Vahl (Clusiaceae) on acute inflammation.

Garcinia humilis is popularly used to treat digestive, intestinal and inflammatory illness. We investigated the in vivo and in vitro effects of the methanol extract of G. humilis leaves (MEGh) on inflammatory cells behavior (migration and chemical mediators release) and hypersensitivity.

Effects of Eugenia umbelliflora O. Berg (Myrtaceae)-leaf extract on inflammation and hypersensitivity.

Ethnopharmacological Relevance: The leaves of Eugenia species are widely used in popular medicine to treat several diseases, such as arthritis, rheumatism and diabetes. Eugenia umbelliflora O. Berg is popularly known in Brazil as "baguaçu", name also conferred to Eugenia jambolana probably due to their apparent similarity.
