Vahl Counteracting Metabolic Syndrome and Depression in Mice on a High-Fat Diet.

Vahl is a plant commonly used in Mexico as a remedy for nervous disorders, inflammatory diseases, and "ringing in the ears"; the latter can be associated with arteriosclerotic conditions and arterial hypertension. Therefore, based on medicinal use, this work aimed to evaluate the hydroalcoholic extract (SeHA, 100 mg/kg) of this plant and two fractions, ethyl acetate (SeFAc, 50 mg/kg), and obtained from SeFAc fractionation denominated SeF3 (10 mg/kg), on several alterations derived from metabolic syndrome (MetS) derived from the ingestion of a high-calorie diet (high-fat diet), in ICR (Institute of Cancer Research) mice, leading to chronic inflammation that results in neurological damage such as depression. Therefore, several MetS-related parameters, such as forced swim tests, hypertension, serum corticosterone levels, glucose, triglycerides, cholesterol, adiposity index, and insulin resistance, will be evaluated.

A Mixture of Kaempferol-3--sambubioside and Kaempferol-3--sophoroside from Prevents Ethanol-Induced Gastric Inflammation, Oxidative Stress, and Histologic Changes.

is used in traditional Mexican medicine to treat gastrointestinal diseases. Therefore, a mixture of Kaempferol--sambubioside and Kaempferol--sophoroside (MaSS) isolated from flowers of this species was tested as a preventive treatment on gastric lesions induced with ethanol in rats. MaSS was obtained by chromatographic methods and administered by oral pathway to male Sprague Dawley rats with ethanol-induced gastric lesions.

Potential Use of Genus in Neuroinflammation Management.

Agavaceae contains about 480 species, commonly used in the production of alcoholic beverages such as tequila and mezcal, making it a resource of economic and cultural importance. Uses of this plant rely mainly on the stem; other components such as the leaves are discarded, generating agro-industrial waste, despite being a source of bioactive and nutraceutical products. Reports show anti-inflammatory and anti-neuroinflammatory effects of these species, with flavonoids and saponins being mainly responsible.

Effect of Argemone mexicana on Local Edema and LPS-Induced Neuroinflammation.

Argemone mexicana L. is a widely used plant in Mexican traditional medicine to treat inflammatory and nervous medical conditions. It has been subjected to several pharmacological and chemical studies in which acute anti-inflammatory activity is indicated.

Effect of Terpenoids and Flavonoids Isolated from Kunth on TPA-Induced Ear Edema in Mice.

In this study, we isolated from the aerial parts of Kunth (i) a new neoclerodane, denominated "bacchofertone"; (ii) four known terpenes: schensianol A, bacchofertin, kingidiol and oleanolic acid; and (iii) two flavonoids: cirsimaritin and hispidulin. All structures were identified by an exhaustive analysis of nuclear magnetic resonance (NMR) and mass spectroscopy (MS). Extracts from aerial parts were screened for anti-inflammatory activity in the mice ear edema model of 12--tetradecanoylforbol-13-acetate mice.

Anti-neuroinflammatory effect of agaves and cantalasaponin-1 in a model of LPS-induced damage.

Chronic neuroinflammation is a key component of many neurodegenerative disorders. Chronic activation of this process produces pro-inflammatory cytokines, prostaglandins and reactive oxygen species that induce brain injury and neuronal dysfunction. Agave species contain saponins, compounds with anti-inflammatory activity.

Anti-inflammatory activity of different agave plants and the compound cantalasaponin-1.

Species of the agave genus, such as Agave tequilana, Agave angustifolia and Agave americana are used in Mexican traditional medicine to treat inflammation-associated conditions. These plants' leaves contain saponin compounds which show anti-inflammatory properties in different models. The goal of this investigation was to evaluate the anti-inflammatory capacity of these plants, identify which is the most active, and isolate the active compound by a bio-directed fractionation using the ear edema induced in mice with 12-O-tetradecanoylphorbol-13-acetate (TPA) technique.
