Ginsenoside Re is a protopanaxatriol-type saponin extracted from the berry, leaf, stem, flower bud, and root of . In recent years, ginsenoside Re (Re) has been attracting attention as a dietary phytochemical. In this review, studies on Re were compiled by searching a combination of keywords, namely "pharmacology," "pharmacokinetics," and "toxicology," in the Google Scholar, NCBI, PubMed, and Web of Science databases.

Corosolic acid (CA) is the main active component of and has been known to serve as several different pharmacological effects, such as antidiabetic, anti-oxidant, and anticancer effects. In this study, effects of CA on the hepatic lipid accumulation were examined using HepG2 cells and tyloxapol (TY)-induced hyperlipidemia ICR mice. CA significantly inhibited hepatic lipid accumulation via inhibition of SREBPs, and its target genes FAS, SCD1, and HMGCR transcription in HepG2 cells.

Tetrahydropalmatine (THP), one of the active components of Rhizoma corydalis, has been reported to exert several pharmacological effects, including anti‑inflammatory, anti‑tumor and analgesic activities. However, its effect on obesity and the underlying molecular mechanisms that may be involved have not yet been elucidated. In the present study, the inhibitory effects of THP on the adipogenesis in 3T3‑L1 adipocytes was examined using hstology, western blotting and RT‑qPCR.

This work concerns the design and synthesis of novel, substituted 5-alkoxythieno[2,3-e][1,2,4]triazolo[4,3-c]pyrimidine derivatives 5a-p prepared from 3-amino-2-thiophenecarboxylic acid methyl ester. The final compounds were screened for their in vivo anticonvulsant activity using maximal electroshock (MES) and subcutaneous pentylenetetrazole (scPTZ) tests. Neurotoxicity (NT) was tested using a rotarod test.

In this study, we investigated the effects of a petroleum ether fraction of Artemisia sacrorum Ledeb. (Compositae) (PEASL) on glucose production through AMP-activated protein kinase (AMPK) activation in human HepG2 cells. PEASL significantly inhibited glucose production in a concentration-dependent manner, and this effect was reversed in the presence of compound C, a selective AMPK inhibitor.

Aims Of Study: Although Artemisia sacrorum Ledeb. (Compositae) has long been used as one kind of oriental folk medicine to treat some liver diseases, the underlying mechanism(s) by which these effects are induced remains to be defined. This study was designed to investigate the hepatoprotective effects of 50% ethanol eluate precipitation of Artemisia sacrorum Ledeb.

This study was designed to investigate the protective effects of the active part of Artemisia sacrorum Ledeb. Extract (ASE) against acetaminophen (APAP)-induced hepatotoxicity in mice. As a result, pretreated with ASE prior to the administration of APAP significantly prevented the increases of aspartate aminotransferase (AST), alanine aminotransferase (ALT), and tumor necrosis factor-alpha (TNF-alpha) levels in serum, and glutathione (GSH) depletion, malondialdehyde (MDA) accumulation in liver tissue.
