Comparison of the nephroprotective effect of [6]-gingerol and the [6]-gingerol-β-cyclodextrin complex against cisplatin-induced AKI.

Cisplatin is an antineoplastic agent effective for the treatment of several cancers. However, due to its nephrotoxicity, its use is limited. Acute kidney injury (AKI) induced by cisplatin is caused by inflammation, apoptosis, and oxidative stress in renal tubular cells.

[8] and [10]-Gingerol reduces urothelial damage in ifosfamide-induced hemorrhagic cystitis via JAK/STAT/FOXO signaling pathway via IL-10.

Acrolein is the main toxic metabolite of ifosfamide (IFO) that causes urothelial damage by oxidative stress and inflammation. Here, we investigate the molecular mechanism of action of gingerols, Zingiber officinale bioactive molecules, as an alternative treatment for ifosfamide-induced hemorrhagic cystitis. Female Swiss mice were randomly divided into 5 groups: control; IFO; IFO + Mesna; and IFO + [8]- or [10]-gingerol.

Inclusion of vitexin in β-cyclodextrin: preparation, characterization and expectorant/antitussive activities.

The study aimed to include the isolated vitexin of in the β-cyclodextrin cavity to improve the solubility of this flavone. Its characterization was performed by techniques such as H NMR/ROESY (Nuclear Magnetic Resonance Spectroscopy), FT-IR (Infrared Spectroscopy with Fourier Transform), SEM (Morphological analysis of IC by Scanning Electron Microscopy) and dissolution study . In addition, the following activities were evaluated in the animal models: expectorant, phenol red dosage in bronchoalveolar lavage and antitussive, cough induced by citric acid.

[10]-Gingerol improves doxorubicin anticancer activity and decreases its side effects in triple negative breast cancer models.

Purpose: Although doxorubicin is widely used to treat cancer, severe side effects limit its clinical use. Combination of standard chemotherapy with natural products can increase the efficacy and attenuate the side effects of current therapies. Here we studied the anticancer effects of a combined regimen comprising doxorubicin and [10]-gingerol against triple-negative breast cancer, which does not respond to hormonal or targeted therapies.

SSi6 promotes cell death by apoptosis through cell cycle arrest and inhibits migration and invasion of MDA-MB-231 human breast cancer cells.

Triple-negative breast cancer subtype is the most aggressive type of breast cancer due to the lack of specific therapeutic targets, having limited treatment options, low survival prognosis and high recurrence rates. In this work, we describe the effects of a semisynthetic derivative of [6]-gingerol (6G) called SSi6, produced by the addition of a 2,4-dinitrophenylhydrazine reagent on several aspects of triple-negative breast cancer biology. Human breast cancer cell lines MDA-MB-231 and MCF-10A were used in the experiments.

Evaluation of the cytotoxicity on breast cancer cell of extracts and compounds isolated from (L.) poit.

is a herb popularly used in Brazil for the treatment of inflammations, pain, bacterial infections and cancer. In the present study, inflorescences (MPIn), leaves (MPL), branches (MPB), root (MPR) extracts and three compounds isolated from MPIn were assayed against breast tumor cell lines. The structures of the three compounds (pectinolide J, hyptolide and pectinolide E) were determined by means of spectroscopic analysis.

[10]-Gingerol Affects Multiple Metastatic Processes and Induces Apoptosis in MDAMB- 231 Breast Tumor Cells.

Background: Triple Negative Breast Cancer (TNBC) represents the approximately 15% of breast cancers that lack expression of Estrogen (ER) and Progesterone Receptors (PR) and do not exhibit amplification of the human epidermal growth factor receptor 2 (HER2) gene, imposing difficulties to treatment. Interactions between tumor cells and their microenvironment facilitate tumor cell invasion in the surrounding tissues, intravasation through newly formed vessels, and dissemination to form metastasis. To treat metastasis from breast and many other cancer types, chemotherapy is one of the most extensively used methods.

Autophagy-dependent apoptosis is triggered by a semi-synthetic [6]-gingerol analogue in triple negative breast cancer cells.

Triple negative breast cancer (TNBC) is very aggressive and lacks specific therapeutic targets, having limited treatment options and poor prognosis. [6]-gingerol is the most abundant and studied compound in ginger, presenting diverse biological properties such as antitumor activity against several types of cancer, including breast cancer. In this study, we show that the semi-synthetic analogue SSi6, generated after chemical modification of the [6]-gingerol molecule, using acetone-2,4-dinitrophenylhydrazone (2,4-DNPH) reagent, enhanced selective cytotoxic effects on MDA-MB-231 cells.

Gingerol suppresses sepsis-induced acute kidney injury by modulating methylsulfonylmethane and dimethylamine production.

Acute kidney injury (AKI) and metabolic dysfunction are critical complications in sepsis syndrome; however, their pathophysiological mechanisms remain poorly understood. Therefore, we evaluated whether the pharmacological properties of 6-gingerol (6G) and 10-gingerol (10G) could modulate AKI and metabolic disruption in a rat model of sepsis (faecal peritonitis). Animals from the sham and AKI groups were intraperitoneally injected with 6G or 10G (25 mg/kg).

[10]-gingerol induces apoptosis and inhibits metastatic dissemination of triple negative breast cancer .

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 ( 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 report on the inhibitory properties of [10]-gingerol against metastatic triple negative breast cancer (TNBC) and .

Synthetic chalcone derivatives as inhibitors of cathepsins K and B, and their cytotoxic evaluation.

A series of chalcone derivatives, 1-15, were prepared by Claisen-Schmidt condensation and evaluated for their cytotoxicities on tumor cell lines and also against proteolytic enzymes such as cathepsins B and K. Of the compounds synthesized, (E)-3-(3,4-dimethoxyphenyl)-1-phenylprop-2-en-1-one (12), (E)-3-(4-chlorophenyl)-1-phenylprop-2-en-1-one (13), (E)-3-(4-methoxyphenyl)-1-phenylprop-2-en-1-one (14), and (E)-3-(4-nitrophenyl)-1-phenylprop-2-en-1-one (15) showed significant cytotoxicities. The most effective compound was 15, which showed high cytotoxic activity with an IC50 value lower than 1 μg/ml, and no selectivity on the tumor cells evaluated.

6-Shogaol inhibits chondrocytes' innate immune responses and cathepsin-K activity.

Scope: Ginger has long been used in traditional Asian medicine to treat osteoarthritis. Indeed, scientific research has reported that ginger derivatives (GDs) have the potential to control innate immune responses. Given the widespread use and demonstrated properties of GDs, we set out to study their anti-inflammatory and anticatabolic properties in chondrocytes.
