Ethnopharmacological Study of and Its Antidiabetic Effect in Rats.

This study aimed to scientifically validate the traditional use of (Gl) leaves as an antidiabetic agent attributed to a community in Mexico. The descriptive ethnobotanical study was conducted in San Miguel Tecpan, a municipality of Jilotzingo, State of Mexico, Mexico, where a structured questionnaire was applied to 44 inhabitants. studies evaluated the acute oral toxicity of Gl leaves in murine and the effects of a leaf infusion on glycemia in normoglycemic and diabetic rats; in addition, the interaction between Gl and metformin (Met) was also evaluated.

Retro-Curcuminoids as Mimics of Dehydrozingerone and Curcumin: Synthesis, NMR, X-ray, and Cytotoxic Activity.

Curcumin and its derivatives have been extensively studied for their remarkable medicinal properties, and their chemical synthesis has been an important step in the optimization of well-controlled laboratory production. A family of new compounds that mimic the structure of curcumin and curcuminoids, here named -curcuminoids (-), was synthesized and characterized using 1D ¹H- and C-NMR, IR, and mass spectrometry; the X-ray structure of , , , , , , and are reported here for the first time. The main structural feature of these compounds is the reverse linkage of the two aromatic moieties, where the acid chloride moiety is linked to the phenolic group while preserving α, β-unsaturated ketone functionality.

Molecular mechanisms involved in the protective effect of the chloroform extract of Selaginella lepidophylla (Hook. et Grev.) Spring in a lithiasic rat model.

Urolithiasis is a multifaceted process, progressing from urine supersaturation to the formation of mature renal calculi. Calcium oxalate, the main component of kidney stones, has toxicological effects on renal epithelial cells. Some medicinal plants have shown pharmacological effects against renal lithiasis, such as Selaginella lepidophylla (Hook.

Hypothyroidism maintained reactive oxygen species-steady state in the kidney of rats intoxicated with ethylene glycol: effect related to an increase in the glutathione that maintains the redox environment.

Our objective was to determine whether hypothyroidism protects against ethylene glycol (EG)-induced renal damage and whether the redox environment participates in the protection process. We used 36 male Wistar rats divided into four groups: (1) euthyroid, (2) euthyroid + 0.75% EG, (3) hypothyroid, and (4) hypothyroid + 0.
