The mammalian lignans enterolactone and enterodiol, which are produced by the microflora in the colon of humans and animals from precursors in foods, have been suggested to have potential anticancer effects. This study determined the production of mammalian lignans from precursors in food bars containing 25 g unground whole flaxseed (FB), sesame seed (SB), or their combination (FSB; 12.5 g each...
Despite the potential cancer preventive effects of flavonoids and lignans, their ability to reduce pancreatic cancer risk has not been demonstrated in epidemiological studies. Our aim was to examine the association between dietary intakes of flavonoids and lignans and pancreatic cancer risk in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort. A total of 865 exocrin...
2 Background: Isoflavones and lignans (phytoestrogens) are dietary components with potential 3 anti-carcinogenic effects. Although the intake of isoflavones and lignans may affect breast 4 cancer treatment and prognosis – and associations may differ by menopausal status post5 diagnosis intake data are limited. 6 Objective: We aimed to describe post-diagnosis isoflavone and lignan intake in newl...
Umbelliferone, 13 lignans and an unusual compound 2-(3,4-methylenedioxyphenyl)propane-1,3-diol, were isolated from the leaves of Juniperus chinensis. The lignans include meso-secoisolariciresinol, 3,4-methylenedioxy-3’,4’dimethoxylignan-9’,9-olide, hibalactone, isohibalactone, 7-oxohinokinin, 7-hydroxyhinokinin, 7-acetyloxyhinokinin, (+ )-xanthoxylol, dihydrodehydrodiconiferyl alcohol, 3-methox...
Ruminal microbiota plays an important role in the conversion of plant lignans into mammalian lignans. The main mammalian lignan present in the milk of dairy cows fed flax products is enterolactone (EL). The objectives of the present study were to investigate the effects of abomasal infusion of flax oil on the metabolism of flax lignans and concentrations of EL in biological fluids of dairy cows...
Lignans are a large class of secondary metabolites in plants, with numerous biological effects in mammals, including antitumor and antioxidant activities. Sesamin, the most abundant furofuran-class lignan in sesame seeds (Sesamum plants), is produced by the cytochrome P450 enzyme CYP81Q1 from the precursor lignan, pinoresinol. In contrast, Forsythia plants produce dibenzylbutyrolactone-class li...
BACKGROUND AND THE PURPOSE OF THE STUDY Stelleropsis antoninae Pobed. (Family: Thymelaeaceae) grows wildly as an herbaceous plant in Iran. Most of the Thymelaeaceous plants contain lignans and neolignans, which have important pharmacologically properties. In the present study, the isolation and identification of the main lignans and neolignans of S. antoninae, which has not been previously repo...
Extracts from Holostylis reniformis were tested in vivo against Plasmodium berghei and in vitro against a chloroquine-resistant strain of Plasmodium falciparum. The hexane extract of the roots was the most active, causing 67% reduction of parasitemia in vivo. From this extract, six lignans, including a new (7'R,8S,8'S)-3',4'-methylenedioxy-4,5-dimethoxy-2,7'-cyclolignan-7-one, were isolated and...
Dietary lignans, quercetin and resveratrol have oestrogenic properties, and animal studies suggest that they synergistically decrease cancer risk. A protective effect of lignans on the development of oesophageal cancer in humans has recently been demonstrated, and the present study aimed to test whether these three phytochemicals synergistically decrease the risk of oesophageal cancer. Data fro...
PURPOSE Vascular endothelial growth factor (VEGF) is a potent stimulator of angiogenesis, which is crucial in cancer progression. We have previously shown that estradiol (E2) increases VEGF in breast cancer. Phytoestrogens are potential compounds in breast cancer prevention and treatment by poorly understood mechanisms. The main phytoestrogens in Western diet are lignans, and flaxseed is a rich...
