Geraniol prevents CCl-induced hepatotoxicity via suppression of hepatic oxidative stress, pro-inflammation and apoptosis in rats.

Carbon tetrachloride (CCl) is a classic chemical hepatotoxicant that triggers liver damage through hepatic exacerbation of oxidative stress. Geraniol (GRL) is a natural bioactive acyclic monoterpene with several pharmacological effects. We thus explored whether GRL could prevent CCl-triggered hepatic toxicity.

Synthesis, Anticancer, Antioxidant, Anti-Inflammatory, Antimicrobial Activities, Molecular Docking, and DFT Studies of Sultams Derived from Saccharin.

A series of -substituted saccharins namely 2-(1,1-dioxido-3-oxobenzo[d]isothiazol-2()-yl) acetonitrile () and (alkyl 1,1-dioxido-3-oxobenzo[d]isothiazol-2(3)-yl) acetate (-) were synthesized, in moderate to excellent yields, from commercially available starting materials by two different approaches and their chemical structures were characterized by spectroscopic techniques (H-NMR, C-NMR, IR, and MS).

Design, Synthesis, and Biological Evaluations of Novel Azothiazoles Based on Thioamide.

Herein we studied the preparation of different thiazoles via the reaction of 2-(3,4-dimethoxybenzylidene)hydrazine-1-carbothioamide () with hydrazonoyl halides under base-catalyzed conditions. The reactions proceed through nucleophilic substitution attack at the halogen atom of the hydrazonoyl halides by the thiol nucleophile to form an -alkylated intermediate. The latter intermediate undergoes cyclization by the loss of water to afford the final products.
