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. This study¡äs objective was to investigate the chem. 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 histochem. and micromorphol. of leaves and stems.Aerial parts of S. terebinthifolia were collected in six states of Brazil, and the essential oil was extracted by hydrodistillation and analyzed by gas chromatog.-mass spectrometry (GC-MS). The histochem. and micromorphol. of leaves and stems were performed using standard reagents, light and field emission SEM, beyond energy-dispersive X-ray spectroscopy. The EOST were evaluated for anti-inflammatory activity and hyperalgesia using the carrageenan-induced paw edema methodol. The EOST showed variation across the six states in its yield (0.40%-0.86%) and chem. composition: hydrocarbon monoterpenes (28.76%-47.73%), sesquiterpenes, (31.43%-41.76%), oxygenated monoterpenes (14.31%-19.57%), and oxygenated sesquiterpenes (4.87%-14.38%). Both ¦Á-pinene and limonene were predominant constituents of essential in five regions, except for one state where ¦Á-phellandrene and limonene were the dominant components. A comprehensive description of the leaf and stem micromorphol. and histochem. was performed. In the in vivo testing, all EOST samples exerted antiedematogenic and anti-hyperalgesic effects, when tested in a carrageenan-induced paw inflammation (mech. and thermal hyperalgesia) model with oral doses of 30 mg/kg. Our results indicate that the EOST samples collected in six Brazilian states differed in their chem. composition but not their anti-inflammatory and antihyperalgesic effects, which was correlated with the synergistic effect of its components, collaborating the etnhopharmacologycal use of this plant due to its an anti-inflammatory effect. Also, micromorphol. and histochem. of leaves and stems presented in this study provide anatomical and microchem. information, which aids species identification.

Geographical variation in the chemical composition, anti-inflammatory activity of the essential oil, micromorphology and histochemistry of Schinus terebinthifolia Raddi. Recommended basis is Cadinene. Products is: https://www.ambeed.com/products/189165-77-3.html, 51905-84-1

With the continuous development of cancer nanotechnol., an important trend in the research is to combine the broad application prospects of functional nanomaterials with recent biol. discoveries and technol. advances. Herein, a cancer cell membrane-camouflaged gold nanocage loading doxorubicin (DOX) and L-buthionine sulfoximine (BSO) (denoted as m@Au-D/B NCs) was constructed as an innovative nanoplatform to confer promising cancer combination therapy by evoking effective ferroptosis and immune responses. Briefly, the loading of BSO and DOX could induce ferroptosis through simultaneous effective glutathione (GSH) consumption and reactive oxygen species (ROS) accumulation. Gold nanocages (AuNCs) with distinct anti-tumor application performance was utilized as ideal nanocarrier for drug loading, evoking photothermal effects and photochem. catalysis to generate more ROS under near-IR (NIR) irradiation Moreover, m@Au-D/B NCs-mediated photothermal therapy (PTT) combined with ROS production could repolarize the tumor-associated macrophages (TAMs) from pro-tumor (M2) phenotype to anti-tumor (M1) phenotype, thus improving tumor-suppressive immune environment and then promoting the activation of effector cells and release of pro-inflammatory cytokines, in which the antitumor responses were evoked robustly in a methodical approach. The anti-tumor effects in vivo implied that m@Au-D/B NCs could significantly inhibit tumor growth without severe toxicity. Hence, this homotypic targeting nanosystem could offer an auspicious anticancer access by triggering combination cancer therapy via ferroptosis and tumor-associated macrophage repolarization mechanism.

A copper-catalyzed cross-dehydrogenative C-H/N-H coupling has been devised to access a series of N-arylated sulfoximines, e,g., I, in high yield from 8-aminoquinoline-derived benzamides and sulfoximines. The reaction is scalable, and mechanistic studies favor the involvement of an organometallic pathway, where C-H bond cleavage is presumed to be the kinetically relevant step. The utility of sulfoximine-coupled benzamides was displayed through the nickel-catalyzed acceptorless dehydrogenative olefination of benzyl alcs.
