Journal Article
Characterization of Potentially Chemopreventive Phenols in Extracts of Brown Rice That Inhibit the Growth of Human Breast and Colon Cancer Cells
TL;DR: Brown rice and bran contain compounds with putative cancer chemopreventive properties and these phenols are present at much lower levels in white than in brown rice, suggesting the consumption of rice bran or brown rice instead of milled white rice may be advantageous with respect to cancer prevention.
Journal ArticleDOI
Plant--fungal interactions: the search for phytoalexins and other antifungal compounds from higher plants.
Renée J. Grayer,Tetsuo Kokubun +1 more
TL;DR: The possible role of phytoalexins in the resistance of rice plants against the fungus Pyricularia oryzae (= Magnaporthe grisea) is discussed, and the future prospects ofphy toalexin research are outlined.
Journal ArticleDOI
Antibacterial and antifungal activity of cicerfuran and related 2-arylbenzofurans and stilbenes.
TL;DR: Cicerfuran was the only 2-arylbenzofuran that showed antimicrobial activity with MICs as low as 25microg/ml, and stilbenes with a free hydroxyl group were active against both bacteria and fungi withMICs in the range 25-100microG/ml.
Journal ArticleDOI
The chemotaxonomic significance of two bioactive caffeic acid esters, nepetoidins A and B, in the Lamiaceae.
Renée J. Grayer,Maria R Eckert,Nigel C. Veitch,Geoffrey C. Kite,Petar D. Marin,Tetsuo Kokubun,Monique S. J. Simmonds,Alan Paton +7 more
TL;DR: The view that the Nepetoideae are a specialised and monophyletic group within the family Lamiaceae is supported, as Nepetoidin B was shown to have a greater antioxidant activity than gallic, rosmarinic and caffeic acids, and showed activity as an insect phagostimulant.
Journal ArticleDOI
Dihydroisocoumarins and a tetralone from Cytospora eucalypticola.
TL;DR: Two dihydroisocoumarins were isolated from a culture filtrate of Cytospora eucalypticola, together with three known di Hydroxymethylmellein, and showed mild antifeedant activity towards Spodoptera littoralis.
