Abstract
The aim of our study was to reveal the effects of long-term consumption of a high-carbohydrate diet (HCD) on metabolic dysfunctions and histopathological liver alterations in Gerbillus tarabuli, as well as to assess the preventive effects of 20-hydroxyecdysone (20E) in the same animals. Contrary to control diet, HCD induces several metabolic disorders including increased adiposity, dyslipidemia, ectopic fat deposition in the liver, associated with higher levels of plasma AST and ALT. These gerbils showed enhanced oxidative stress with liver damages characteristic of steatohepatitis development. By contrast, adding 20E to HCD resulted in a dose-dependent reduction of all changes induced by HCD. In addition, the hepatoprotective effect of 20E was demonstrated by decreased plasma concentrations of AST, ALT and of hepatic malondialdehyde. Our results suggest that G. tarabuli represents a good model to study diet-induced metabolic disorders and hepatic dysfunctions. Moreover, they demonstrate the efficacy of 20E treatment to counteract the damaging effects of HCD.

Abstract
Eight new neo-clerodane diterpenoids (1-8) were acquired from the aerial parts of Ajuga pantantha. Spectroscopic data analysis permitted the definition of their structures, and experimental and calculated electronic circular dichroism data were used to define their absolute configurations. Compounds 2 and 4-8 were found to have NO inhibitory effects with IC50 values of 20.2, 45.5, 34.0, 27.0, 45.0, and 25.8 μM, respectively. The more potent compounds 2, 6, and 8 were analyzed to establish their anti-inflammatory mechanism, including regulation of the expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) proteins as well as their binding interactions with the two proteins.
