We report mechanism-based evidence for the anticancer and chemopreventive efficacy of [6]-gingerol, the major active principle of the medicinal plant, Ginger (Zingiber officinale), in colon cancer cells. The compound was evaluated in two human colon cancer cell lines for its cytotoxic effect and the most sensitive cell line, SW-480, was selected for the mechanistic evaluation of its anticancer ...

Sini decoction is a well-known formula of traditional Chinese medicine, which has been used to treat cardiovascular disease for many years. Previously, we demonstrated that Sini decoction prevented doxorubicin-induced heart failure in vivo. However, its active components are still unclear. Thus, we investigated the active components of Sini decoction and their cardioprotective mechanisms in the...

The PT-domain of Polyketide synthase A (PksA) is crucial product template that controls the aldol cyclization and aromatization to create polyketide precursor. precursor leads biosynthesis of aflatoxin secondary metabolites. Being carcinogenic in nature these metabolic, efforts have been made explore novel inhibitors targeting PksA. Previously, [6]-gingerol reported as a prospective inhibitor f...

The inotropic/lusitropic effects of beta-adrenergic agonists on the heart are mediated largely by protein kinase A (PKA)-catalyzed phosphorylation of phospholamban, the natural protein regulator of the Ca2+ pump present in sarcoplasmic reticulum (SR) membranes. Gingerol, a plant derivative, is known to produce similar effects when tested in isolated cardiac muscle. The purpose of the present st...

Pseudomonas aeruginosa is a well-known pathogenic bacterium that forms biofilms and produces virulence factors via quorum sensing (QS). Interfering with normal QS interactions between signal molecules and their cognate receptors is a developing strategy for attenuating its virulence. Here we tested the hypothesis that 6-gingerol, a pungent oil of fresh ginger, reduces biofilm formation and viru...

Introduction: Research has shown that gold nanoparticles (AuNPs) can damage the physiological processes of brain tissue. Given the antioxidant properties of gingerol (GING), this study aimed to determine the protective effect of 6-gingerol on hippocampal levels of brain-derived neurotrophic factor (BDNF), nerve growth factor (NGF), DNA oxidative damage, and the amount of Bax and Bcl2 apoptosis ...

Hydroxyphenylalkanes and diarylheptanoids possess potential therapeutic value in different pathophysiological conditions, such as malignancy. In the current study, naturally isolated hydroxyphenylalkane and diarylheptanoid compounds were investigated for potential chemo-modulatory effects in addition to potential vascular protective roles with doxorubicin. Diarylheptanoids showed stronger antio...

A sensitive and accurate high-performance thin layer chromatography (HPTLC) method has been developed to determine the quantity of 6-gingerol in the methanolic extract of Zingiber officinale containing dietary supplements, teas and commercial creams. 6-gingerol was separated on aluminumbacked silica gel 60 F254 plates with n-hexane:ethyl acetate 40:60 (%, v/v) as mobile phase. A compact band wa...

To study the effects of [6]-gingerol, a ginger phytochemical, on tight junction (TJ) molecules, we investigated TJ tightening and signal transduction pathways in human pancreatic duct cell-derived cancer cell line PANC-1. The following methods were utilized: MTT assay to determine cytotoxicity; zymography to examine matrix metalloproteinase (MMP) activities; transepithelial electrical resistanc...

There is increasing interest in the use of non-toxic natural products for the treatment of various pathologies, including cancer. In particular, biologically active constituents of the ginger oleoresin (Zingiber officinale Roscoe) have been shown to mediate anti-tumour activity and to contribute to the anti-inflammatory, antioxidant, antimicrobial, and antiemetic properties of ginger. Here we r...
