Toxicological analysis and anti-inflammatory and antioxidant evaluations of extract, fractions and secoxyloganin obtained from Guettarda viburnoides Cham. & Schltdl. in mice.

Ethnopharmacological Relevance: Guettarda viburnoides, "veludinho do campo," is traditionally used for the treatment of pain and inflammatory conditions in humans; however, only one scientific study has reported this effect in an ear inflammatory model. Therefore, it is necessary to explore other in vivo models and the chemical composition of this medicinal plant.

Aim Of The Study: A chemical investigation of methanolic extract of G.

Guettarda viburnoides Cham. & Schltdl.: Neuroprotective Activities in Mice, Molecular Docking and Microchemical and Morphoanatomical Characteristics of Leaves and Stems.

Background: Guettarda viburnoides Cham. & Schltdl., "veludinho do campo", is used in the Brazilian Amazon for its effects on the central nervous system (CNS) as a "brain tonic"; however, scientific evidence is needed to elucidate its ethnobotanical uses.

Geographical variation in the chemical composition, anti-inflammatory activity of the essential oil, micromorphology and histochemistry of Schinus terebinthifolia Raddi.

Ethnopharmacological Relevance: Schinus terebinthifolia Raddi (Anacardiaceae) is rich in essential oil, distinguished by a predominance of monoterpenes and sesquiterpenes, it being widely used in traditional medicine for the treatment of inflammations.

Aim Of Study: This study's objective was to investigate the chemical composition of the essential oil of S. terebinthifolia (EOST) collected in six states of Brazil, evaluate its anti-inflammatory effects in mice, and analyze the histochemistry and micromorphology of leaves and stems.

Synthesis, Characterization, Antiproliferative Activity of Galloyl Derivatives and Investigation of Cytotoxic Properties in HepG2/C3A Cells.

Background: Appropriate substituents in the galloyl group could lead to significant biological properties.

Objectives: Novel galloyl-substituted compounds bearing 2-substituted-1, 3, 4-oxadiazol-5-yl, 5- substituted-1,2,4-triazol-3-yl, and carboxamide groups were synthesized and evaluated for their antiproliferative activity. Additionally, galloyl hydrazide (2) was evaluated by performing cytotoxicity, membrane integrity, cell cycle, and apoptosis assays in HepG2/C3A cells.

Variation in essential oil components and anti-inflammatory activity of Allophylus edulis leaves collected in central-western Brazil.

Ethnopharmacological Relevance: An infusion obtained from the leaves of "chal-chal" (Allophylus edulis Radlk.) is used for popular treatment of intestinal disorders and as an anti-inflammatory throat treatment. Because of the anti-inflammatory medicinal folk use, a previous work reported scientific research confirming the anti-inflammatory activity of A.
