epicatechin/neoplasms

Lung cancer ranks number one among the all cancer types in the world, out of which 85% are non-small cell lung cancer (NSCLC). In case of NSCLC, a substitution mutation of Leu 858 Arg (L858R) in the gene of Epidermal Growth Factor Receptor (EGFR) has been reported. Hence, targeting EGFR containing

We report an improved synthesis of bis(5,7,3',4'-tetra-O-benzyl)epicatechin 4beta,8-dimer (3) from 5,7,3',4'-tetra-O-benzylepicatechin (1) and 5,7,3',4'-tetra-O-benzyl-4-(2-hydroxyethoxy)epicatechin (2) by replacing the previously employed Lewis acid, titanium tetrachloride, with the clay mineral

Curcumin, a phenolic compound isolated from the plant Curcuma longa (Linn), is ingested every day in the Indian subcontinent and is well reported to possess cancer-preventive activity. To achieve effective cancer prevention with curcumin, we need to find a new method to enhance the effects of

The tea flavonoid epicatechin gallate (ECG) exhibits a wide range of biological activities. In this study, the in vitro anticancer effects of ECG on SW480 colon cancer cell line was investigated by analyzing the cell cycle, apoptosis, key proteins involved in cellular survival/proliferation, namely

OBJECTIVE (-)-Epicatechin is a major constituent of Bulnesia sarmienti, which is known to possess anticancer properties. Here we report that (-)-epicatechin isolated from B. Sarmienti inhibited growth and induced apoptosis of SW480 human colon cancer cells. METHODS Cells were treated with different

Green tea, next to water, is the most popular and commonly consumed beverage in the world, especially in eastern countries. In prior studies we have shown that the polyphenolic fraction isolated from green tea (GTP) exerts antigenotoxic effects in various mutagenicity test systems (Mutat. Res., 223:

Hypoxia-inducible factor-1 (HIF-1) is a transcription factor that induces oxygen-regulated genes in response to reduced oxygen conditions (hypoxia). Expression of the oxygen-regulated HIF-1alpha subunit correlates positively with advanced disease stages and poor prognosis in cancer patients. Green

Gap junctional intercellular communication (GJIC) is a direct signaling pathway for neighboring cells. Disturbances in GJIC are suggested to play a role in carcinogenesis and may be involved in cardiac arrhythmia. Tumor promoters like 12-O-tetradecanoylphorbol-13-acetate (TPA) are capable of

Epicatechin is a natural flavonoid found in green tea. It has been reported to possess an immense antioxidant effect which contributes to its therapeutic effect against a handful of ailments. In this review, we discuss its therapeutic role in the management of two of the most important human

With recent insight into the mechanisms involved in diseases, such as cardiovascular disease, cancer, stroke, neurodegenerative diseases, and diabetes, more efficient modes of treatment are now being assessed. Traditional medicine including the use of natural products is widely practiced around the

Catechins, naturally occurring flavonoids derived from wine and green tea, are known to exhibit multiple health benefits. Epigallocatechin gallate (EGCG) is one of the most widely investigated catechins, but its efficacy in cancer therapy is still inconsistent and limited. The poor stability of EGCG

Curcumin (from curry) (C) is highly potent against cervical cancer cells (CCC), but poor bioavailability has limited its clinical use. Similar natural polyphenols resveratrol (from grapes) (R), and epicatechin gallate (from green tea) (E) also display activity against CCC. By treating CCC (HeLa)

Epithelial-to-mesenchymal transition (EMT) and invasion potential have been considered as essential factors in cancer metastasis, which is the major cause of cancer death. EMT is a multi-step process that involves gain invasion, cytoskeleton change, cell adhesion, and proteolytic extracellular

Green tea and grape phenolics inhibit cancer growth and modulate cellular metabolism. Targeting the tumor metabolic profile is a novel therapeutic approach to inhibit cancer cell proliferation. Therefore, we treated human colon adenocarcinoma HT29 cells with the phenolic compound epicatechin gallate

Humans ingest about 1 g of flavonoids daily in their diet, and they are increasingly being associated with cytoprotective antitumour properties. The mechanism(s) responsible for these effects have not yet been elucidated but may involve interaction with xenobiotic metabolising enzymes to alter the
