J Food Sci 2019; 84:339-348. [PMID: 30726580 DOI: 10.1111/1750-3841.14437] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2018] [Revised: 12/01/2018] [Accepted: 12/15/2018] [Indexed: 01/23/2023]
Abstract
This study assessed the effect of Kaempferia parviflora, also known as black ginger (BG), and its ethanol extract (BGE) on peroxisome proliferator-activated receptor (PPAR) γ agonistic activity, glucose tolerance, fat accumulation, and lipids-induced hypertriglyceridemia in mice. PPARγ ligand-binding capacity in vitro and polymethoxy flavone contents were highly observed in organic solvent extracts. In an animal experiment A, male diabetic Nagoya-Shibata-Yasuda mice were divided into five dietary groups and fed each diet for 8 weeks: AIN-93G diet (low-fat [LF] diet), high-fat (HF) diet, HF diet supplemented with 1% BG, HF diet supplemented with 0.19% BGE, and HF diet supplemented with pioglitazone (PPARγ agonist, 3 mg/kg/day) as a PPARγ agonistic positive control. As determined from glucose and insulin tolerance tests, plasma glucose levels were improved in the BG and BGE groups. The BGE extract suppressed fat accumulation in adipose tissues, liver, and muscles without changing the plasma adiponectin level. In an animal experiment B, in order to investigate the effect of BG and BGE on lipid-induced hypertriglyceridemia, male ddY mice were divided into three test groups: control, BG-administered group (500 mg/kg), and BGE-administered group (100 mg/kg). The plasma triacylglycerol level was not different among the groups during the lipids administration test. These results conclude that the BGE extract containing several kinds of polymethoxy flavones showed PPARγ ligand-binding capacity in vitro and prevented obesity and insulin resistance independent of adiponectin secretion in mice. PRACTICAL APPLICATION: Kaempferia parviflora, also known as black ginger (BG), is often used as a folk medicine and a functional food material to prevent metabolic syndrome mainly in Asian regions. Here, we have clarified that ethanol extract from BG (BGE) contains several kinds of polymethoxy flavones to show PPARγ ligand-binding capacity and is an active extract for the improvement of obesity and insulin resistance. The BGE is expected to be applied for functional food materials in health food markets. Also, polymethoxy flavones to show PPARγ ligand-binding capacity can be generally applied as a physiological active compound of functional food supplements.

Abstract
Tyrosine kinase inhibitors (TKI) are a novel and target-specific class of anticancer drugs. One drawback of TKI therapy is cancer resistance to TKI. An important TKI resistance mechanism is enhanced efflux of TKI by efflux transporters, such as Breast Cancer Resistance Protein (BCRP), in cancer cells. 5,7-Dimethoxyflavone (5,7-DMF) is a natural flavonoid which was recently reported to be a potent BCRP inhibitor. In the current study, the effect of 5,7-DMF on the disposition of sorafenib, a TKI which is a good substrate of BCRP, was investigated both in vitro in efflux transporter expressing cells and in vivo in mice. 5,7-DMF significantly inhibited Bcrp1-mediated sorafenib efflux in a concentration dependent manner in MDCK/Bcrp1 cells, with EC50 value of 8.78 μM. The pharmacokinetics and tissue distribution of sorafenib (10 mg/kg) with and without co-administration of 75 mg/kg 5,7-DMF were determined. With 5,7-DMF, the AUC of sorafenib in plasma was 47,400 ± 4790 ng·h/mL, which was significantly higher than 27,300 ± 2650 ng·h/mL in sorafenib alone group. In addition, compared to sorafenib alone group, great increase in sorafenib AUC was observed in most tissues collected when sorafenib was given with 5,7-DMF. Our results indicated that 5,7-DMF may represent a novel and very promising chemosensitizing agent for BCRP-mediated anticancer drug resistance due to its low toxicity and potent BCRP inhibition.

Abstract
Lychnopholide is a sesquiterpene lactone usually obtained from Lychnophora and Eremanthus species and has pharmacological activities that include anti-inflammatory and anti-tumor. Lychnopholide isolated from Eremanthus matogrossenssis was analyzed in this study. The aims of this study were to develop and validate an analytical methodology by LC-MS/MS and to quantify lychnopholide in rat plasma. Chromatographic separation was achieved on a C18 column using isocratic elution with the mobile phase consisting of methanol and water (containing 0.1% formic acid) at a flow rate of 0.4 mL/min. The detection was performed in multiple-reaction monitoring mode using electrospray ionization in positive mode. The method validation was performed in accordance with regulatory guidelines and the results met the acceptance criteria. The linear range of detection was 10-200 ng/mL (r > 0.9961). The intra- and inter-day assay variability were <6.2 and <11.7%, respectively. The extraction recovery was approximately 63% using liquid-liquid extraction with chloroform. Lychnopholide was detected in plasma up to 60 min after intravenous administration in rats. This rapid and sensitive method for the analysis of the sesquiterpene lactone lychnopholide in rat plasma can be applied to pharmacokinetic studies of this compound.
