“…Along with our collaborators, we have reported that [6]-shogaol was more effective than [6]-gingerol in inhibiting 12-O-tetradecanoylphorbol-13-acetate-induced tumor promotion in mice (Wu et al, 2010). Furthermore, Dugasani et al (2010) The pharmacokinetics of [6]-shogaol in mice and in humans have been investigated (Zick et al, 2008(Zick et al, , 2010Wang et al, 2009;Asami et al, 2010;Iwabu et al, 2010). Yu et al (2007) reported that free [6]-shogaol and glucuronidated and sulfated metabolites of [6]-shogaol were detected in the plasma with peak concentrations of 13.6 Ϯ 6.9 ng/ml, 0.73 Ϯ 0.54 g/ml, and 0.047 Ϯ 0.035 g/ml, respectively, 1 h after oral administration of 2.0 g of ginger extracts (containing 45.04 mg of [6]-shogaol) in humans.…”

“…), a member of the Zingiberaceae family, has been cultivated for thousands of years as a spice and for medicinal purposes. Ginger has received extensive attention because of its antioxidant, anti-inflammatory, and anticancer activities (Kawai et al, 1994;Surh, 2002;Shukla and Singh, 2007;Zick et al, 2008;Wang et al, 2009). The major pharmacologically active components of ginger are gingerols and shogaols (Masada et al, 1974;Jiang et al, 2005Jiang et al, , 2006Jiang et al, , 2007Yu et al, 2007).…”

ABSTRACT:Ginger has received extensive attention because of its antioxidant, antiinflammatory, and antitumor activities. However, the metabolic fate of its major components is still unclear. In the present study, the metabolism of [6]-shogaol, one of the major active components in ginger, was examined for the first time in mice and in cancer cells. Thirteen metabolites were detected and identified, seven of which were purified from fecal samples collected from

“…The antioxidative, anti-inflammatory, and antitumor properties of ginger (Zingiber officinale Roscoe, Zingiberaceae) have been reported in previous studies (1)(2)(3)(4)(5). Various clinical trials have evaluated ginger extracts to decrease lipid levels (6), treat arthritis (7,8), prevent nausea and vomiting (9)(10)(11), and reduce pain in women with primary dysmenorrhea (12).…”

Abstract. Ginger extracts have been studied in various clinical trials for different indications. However, the pharmacokinetics of the ginger active constituents in human biological matrices is not well investigated. This study aims to develop a LC-MS/MS method for simultaneous measurement of 6-, 8-, and 10-gingerols and 6-shogaol and study their pharmacokinetics in human plasma and colon tissues. A sensitive LC-MS/MS method was established and validated with a low limit of quantification of 2-5 ng/ mL. The intra-and inter-day accuracy ranged from −7.3% to 10.4% and from −9.4% to 9.8%, respectively. The intra-and inter-day precision ranged from 0.9% to 10.9% and from 2.0% to 12.4%, respectively. The glucuronide and sulfate metabolites of 6-, 8-, and 10-gingerols and 6-shogaol in plasma and colon tissues were quantified after hydrolysis with β-glucuronidase and sulfatase. After oral dosing of 2.0 g ginger extracts in human, free 10-gingerol and 6-shogaol were detected in plasma with peak concentrations (9.5±2.2 and 13.6±6.9 ng/mL, respectively) at 1 h after oral administration, but no free 6-gingerol and 8-gingerol were detected in plasma from 0.25 to 24 h. The peak concentrations of glucuronide metabolites of 6-, 8-, and 10-gingerols and 6-shogaol were 0.47±0.31, 0.17±0.14, 0.37±0.19, and 0.73±0.54 μg/mL at 1 h, respectively. The peak concentrations of the sulfate metabolites of 6-, 8-, and 10-gingerols and 6-shogaol were 0.28±0.15, 0.027±0.018, 0.018±0.006, and 0.047±0.035 μg/mL at 1 h, respectively. Very low concentrations (2-3 ng/mL) of 10-gingerol glucuronide and sulfate were found in colon tissues. Pharmacokinetic analysis showed that half-lives of these four analytes and their metabolites were 1-3 h in human plasma. No accumulation was observed for 6-, 8-, and 10-gingerols and 6-shogaol and their metabolites in both plasma and colon tissues after multiple daily dosing.

“…It has been used since antiquity for its health benefits (13). Extracts obtained from its roots usually contain polyphenol compounds, such as [6]-gingerol, [8]gingerol, and [10]-gingerol, which have been cited as the main components responsible for its pharmacological effects (14,15). Among other potential mechanisms, ginger has antioxidant (15)(16)(17) and anti-inflammatory properties (15,18,19).…”

. Histopathological findings of tubular degeneration and inflammatory cell infiltration reinforced GM-induced nephrotoxicity. All these alterations were attenuated by previous oral treatment with GF. Animals from the GM؉GF groups showed amelioration in renal function parameters and reduced lipid peroxidation and nitrosative stress, in addition to an increment in the levels of glutathione (GSH) and superoxide dismutase (SOD) activity. Gingerols also promoted significant reductions in mRNA transcription for TNF-␣, IL-2, and IFN-␥. These effects were dose dependent. These results demonstrate that GF promotes a nephroprotective effect on GM-mediated nephropathy by oxidative stress, inflammatory processes, and renal dysfunction.
