A first attempt was made to study the fluorescence quenching, structure and unfolding nature of the purified Zingiber montanum (J.Koenig) Link ex A.Dietr. cysteine protease glycoprotein (ZCPG). ATR-IR spectra showed the presences of amide groups along with carbohydrate stretch indicating the glycoprotein nature. UV-vis spectra determined the presences of peptide groups and aromatic sidechains of tyrosine, tryptophan and phenylalanine. Far UV-Circular Dichroism spectrum revealed that the secondary structure consists of 47...

BACKGROUND: [6]-Gingerol, a major component of Zingiber officinale, was previously reported to ameliorate hyperglycemia in type 2 diabetic mice. Endocrine signaling is involved in insulin secretion and is perturbed in db/db Type-2 diabetic mice. [6]-Gingerol was reported to restore the disrupted endocrine signaling in rodents. In this current study on Lepr(db/db) diabetic mice, we investigated the involvement of endocrine pathway in the insulin secretagogue activity of [6]-Gingerol and the mechanism(s) through which [6]-Gingerol ameliorates hyperglycemia...

Ulcerative colitis is one of the most common types of inflammatory bowel disease and is multifactorial and relapsing. 6-Gingerol, a component of gingerols extracted from ginger (Zingiber officinale), has been reported to improve ulcerative colitis. The present study aims to investigate the therapeutic efficacy of two analogous forms of 6-gingerol, 8-gingerol, and 10-gingerol, on ulcerative colitis. Colitis was induced in rats through consumption of 5% (w/v) dextran sulfate sodium drinking water for 7 consecutive days...

Plant-derived immunomodulators and anti-cancer agents have attracted a lot of interest from natural product scientists for their efficacy and safety and their significant contribution towards understanding targeted drug action and drug delivery mechanisms. Zerumbone, the main constituent of Zingiber zerumbet rhizomes, has been investigated for its wide-spectrum role in treating multitargeted diseases. The rhizomes have been used as food flavoring agents in various cuisines and in herbal medicine. Many in vivo and in vitro studies have provided evidence of zerumbone as a potent immunomodulator as well as a potential anti-cancer agent...

6-Gingerol (6-Gin), an active constituent of Zingiber officinale, has been reported to have anti-inflammatory, anti-oxidative, anti-cancerous etc. bioactivities. However, little is known about its endothelial protective effects and the underlying mechanisms. In this study, our purpose was to investigate the protective effects of 6-Gin and its underlying mechanisms. HUVECs were exposed to high glucose (HG, 33mM glucose) for 48h, followed by 50μM 6-Gin with or without LY294002 (10μM), AKT inhibitor IV (0.5μM) or L-NAME (5mM) for another 24h...

Occupational exposure to low-level ionizing radiation (<1 Gy) was shown to enhance cell protection via attenuating an established inflammatory process. Nicotine, a major toxic component of cigarette smoke, is responsible for smoking-mediated renal dysfunction. The present study was therefore aimed to investigate the protective impact of ginger Zingiber officinale selenium nanoparticles (SeNPs) with whole-body low-dose gamma radiation (γ-R) against nicotine-induced nephrotoxicity in male albino rats. Nicotine intoxication was induced with 0...

C Anisha, E K Radhakrishnan
Endophytic fungi associated with rhizomes of four cultivars of Zingiber officinale were identified by molecular and morphological methods and evaluated for their activity against soft rot pathogen Pythium myriotylum and clinical pathogens. The volatile bioactive metabolites produced by these isolates were identified by GC-MS analysis of the fungal crude extracts. Understanding of the metabolites produced by endophytes is also important in the context of raw consumption of ginger as medicine and spice.
