8 prenylnaringenin/neoplasms

The discovery that the hop constituent 8-prenylnaringenin (8PN) shows potent estrogenic activity, higher than that of the known phytoestrogens coumestrol, genistein and daidzein, has spurred an intense activity aimed at elucidating its biological profile and its dietary relevance connected with the

Xanthohumol (XN) and 8-prenylnaringenin (8PN) are hop (Humulus lupulus L.) polyphenols studied for their chemopreventive effects on certain cancer types. The breast cancer line MCF-7 was treated with doses ranging from 0.001 to 20 µM of XN or 8PN in order to assess the effects on cell viability and

The hops plant (Humulus lupulus L.) is an essential ingredient in beer and contains a number of potentially bioactive prenylflavonoids, the predominant being the weakly estrogenic isoxanthohumol (Ix), which can be converted to the more strongly estrogenic 8-PN by the colonic microbiota. The aim of

OBJECTIVE The absorption potential and metabolism of 8-prenylnaringenin (8-PN) from hops (Humulus lupulus L.) were investigated. 8-PN is a potent estrogen with the potential to be used for the relief of menopausal symptoms in women. METHODS Monolayers of the human intestinal epithelial cancer cell

METHODS Hops (Humulus lupulus L.) produce unique prenylflavonoids that exhibit interesting bioactivities. This study investigates the interactions between selected prenylflavonoids and breast cancer resistance protein (BCRP/ABCG2), an efflux transporter important for xenobiotic bioavailability and

Several analogues of 7-O- and 4'-O-substituted isoxanthohumol and 8-prenylnaringenin, the strongest known phytoestrogen and potential anticancerogenic agent, were synthesized. Acyl, alkyl, and allyl derivatives of isoxanthohumol underwent the demethylation process using MgI(2 )× 2Et(2)O in anhydrous

Cancer metastasis is the main cause of death (90%), and only recently we have gained some insight into the mechanisms by which metastatic cells arise from primary tumors and target to specific organs. Cysteine X Cysteine (CXC) chemokine receptor 4 (CXCR4), initially linked with leukocyte

Flavonoids form a substantial group of secondary plant metabolites that display several health-promoting effects. Therefore, prenylflavonoids, a subclass of flavonoids, have attracted increasing attention. Here, we investigated the possible anti-cancer potential of 6-prenylnaringenin (6-PN) and

Xanthohumol (XN), a prenylated chalcone unique to hops (Humulus lupulus) and two derived prenylflavanones, isoxanthohumol (IX) and 8-prenylnaringenin (8-PN) gained increasing attention as potential anti-diabetic and cancer preventive compounds. Two enzymes of the aldo-keto reductase (AKR)

Flavonoids with hydrophobic e.g. prenyl substituents might constitute the promising candidates for multidrug resistance (MDR) reversal agents. The interaction of 8-prenylnaringenin (8-isopentenylnaringenin), a potent phytoestrogen isolated from common hop (Humulus lupulus), with two multidrug

Chalcones xanthohumol (X) and desmethylxanthohumol (DMX), present in hops (Humulus lupulus L.), and the corresponding flavanones isoxanthohumol (IX, from X), 8-prenylnaringenin (8-PN, from DMX), and 6-prenylnaringenin (6-PN, from DMX), have been examined in vitro for their anti-proliferative

Gliomas are one of the most aggressive and treatment-resistant types of human brain cancer. Identification and evaluation of anticancer properties of compounds found in plants, such as naringenin (N) and 8-prenylnaringenin (8PN), are among the most promising applications in glioma therapy. The

Prenylated chalcones and flavonoids gained increasing attention not only in nutrition but also in cancer prevention because of their biological and molecular activities in humans, which have been extensively investigated in vitro or in preclinical studies. These naturally occurring compounds exhibit

Xanthohumol (X), isoxanthohumol (IX), 8-prenylnaringenin (8PN) and 6-prenylnaringenin (6PN), prenylflavonoids from hop (Humulus lupulus L.), were investigated for their cytotoxicity and the mechanism by which they exert cell death when incubated with prostate cancer cell lines PC-3 and DU145. All
