tectochrysin/neoplasms

The purpose of this study was to evaluate the enhancing potency of tectochrysin, a flavonoid isolated from Alpinia oxyphylla Miquel by combining cetuximab, an anti-EGFR monoclonal antibody, on human colon cancer cell growth through further inhibition of EGFR pathway. HCT116 and SW480 colon cancer

BACKGROUND Flavonoids are a diverse family of natural phenolic compounds commonly found in fruits and vegetables. Epidemiologic studies showed that flavonoids also reduce the risk of colon cancer. Tectochrysin is one of the major flavonoids of Alpinia oxyphylla Miquel. However, the anti-cancer

Phenolic compounds (flavonoids and phenolic acid derivatives) are the most important pharmacologically active ingredients, and these compounds could inhibit proliferation of human cancer cells by inducing of apoptotic cell death. Here we focused on the anticancer effects of tectochrysin on human

In this study, we investigate the underlying molecular mechanism of the effect of tectochrysin on LPS-primed macrophages. As measured by western blot, RT-PCR, and ELISA, tectochrysin inhibits extracellular signal-related kinase 1/2 (ERK1/2) phosphorylation and sequentially suppressed downstream

Aging is related to the lowered overall functioning and increased risk for various age-related diseases in humans. Tectochrysin is a flavonoid compound and rich in a traditional Chinese Medicine Alpinia oxyphylla Miq., which has antioxidant, anti-inflammatory, anti-cancer, anti-bacterial,

Methoxylated flavones were recently shown to be promising cancer chemopreventive agents. Their high metabolic stability compared with the hydroxylated analogs was shown in our laboratory using the human hepatic S9 fraction with cofactors for glucuronidation, sulfation, and oxidation. In the present

OBJECTIVE To study the chemical constituents in fruit of Alpinia oxyphylla and their cytotoxicities on cancer cell lines. METHODS Compounds were isolated and purified by various column chromatographic methods. Their structures were determined by physico-chemical properties and spectral analyses.

BACKGROUND Propolis is a resinous hive product collected by honeybees from various plant sources. It is widely used in traditional medicine and is reported to have a broad spectrum of pharmacological effects (antibacterial, antihepatoxic, antioxidative, anti-inflammatory, etc.). Thus the aim of this

New Zealand propolis is a "European" type propolis obtained by honey bees mainly from exudates of poplar. European type propolis is known to have anti-inflammatory and anti-cancer properties and this activity has been attributed to some of the main constituents such as chrysin and CAPE (caffeic acid
