The destruction of cancer cells with chemotherapeutic agents is normally achieved through apoptosis. We previously introduced two synthetic halogenated flavanone derivatives, 3',7-dichloroflavanone (3'-7 DCF) and 3',6-dichloroflavanone (3'-6 DCF), as potential apoptosis-inducing agents. In the
Medicinal flowers. XXVII. New flavanone and chalcone glycosides, arenariumosides I, II, III, and IV, and tumor necrosis factor-alpha inhibitors from everlasting, flowers of Helichrysum arenarium.

The methanolic extract from the flowers of Helichrysum arenarium L. MOENCH was found to show inhibitory effect on tumor necrosis factor-alpha (TNF-alpha, 1 ng/ml)-induced cytotoxicity in L929 cells. From the methanolic extract, 50 constituents including four new flavanone and chalcone glycosides
New geranylated flavanones from the fruits of Paulownia catalpifolia Gong Tong with their anti-proliferative activity on lung cancer cells A549.

Three new geranylated flavanones, named as paucatalinone A (1), B (2), and isopaucatalinone B (3), were isolated from the fruits of Paulownia catalpifolia Gong Tong (Scrophulariaceae). Their structures were well determined by means of IR, MS, 1D and 2D NMR, and CD techniques. Paucatalinone A (1) is
The tumor-growth inhibitory activity of flavanone and 2'-OH flavanone in vitro and in vivo through induction of cell cycle arrest and suppression of cyclins and CDKs.

We investigated the antiproliferative effects of synthetic flavanone derivatives using an MTT assay in MCF-7 and MDA-MB-453 cells. When cells were treated with synthetic flavanone derivatives in concentrations ranging from 1 to 200 microM for 48 h, cell growth decreased at concentrations >50 microM.

BACKGROUND
Natural products with diverse bioactivities are becoming an important source of novel agents with medicinal potential. Cancer is a devastating disease that causes the death of millions of people each year. Thus, intense research has been conducted on several natural products to develop

BACKGROUND
The incidence and mortalities from cancers remain on the rise worldwide. Despite significant efforts to discover and develop novel anticancer agents, many cancers remain in the unmet need category. As such, efforts to discover and develop new and more effective and less toxic agents

Naringenin has been shown to display various biological effects such as antioxidant, anticancer, anti-inflammatory, and antiviral activities. Taxifolin inhibits the production of lipopolysaccharide-induced prostaglandin E, and fustin suppresses the activity of acetylcholinesterase. They all belong
Synthetic flavanones augment the anticancer effect of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL).

Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is considered as the most promising anticancer agent in the TNF superfamily because of its selective cytotoxicity against tumor cells versus normal primary cells. However, as more tumor cells are reported to be resistant to

Flavanones, the main polyphenols of citrus fruits, are thought to contribute to the protective effects of these fruits against cardiovascular diseases and cancer. The metabolism of naringin (naringenin 7-O-neohesperidoside) is studied here in healthy (sham-operated, ShO) and tumor-bearing (TuB)

Flavonols, flavanones and flavones (FLAV) are sub-classes of flavonoids that exert cardioprotective and anti-carcinogenic properties in vitro and in vivo. We aimed to estimate the FLAV dietary intake, their food sources and associated lifestyle factors in ten European countries participating in the
