The present application describes process for preparing an ortho-allylated hydroxy aryl compounds such as compounds of Formula (I) by reacting an allylic alcohol with a hydroxy aryl compound in the presence of aluminum compound selected from alumina and aluminum alkoxides and in a non-protic solvent wherein at least one carbon atom ortho to the hydroxy group in the hydroxy aryl compound is unsubstituted. The present application also includes compounds of Formula (I).
SAR analysis revealed that the anti-proliferative activity of the xanthones is substantially influenced by the position and number of attached hydroxyl and prenyl groups, and the presence of hydroxyl group ortho to the carbonyl function of xanthone scaffold contributes significantly to their cytotoxicity. The new prenylatedxanthone 20 with a relatively simple structure, namely 1,3,8-trihydroxy-2-prenylxanthone

[EN] A baby food composition for consumption by, and to provide nutrition to a baby, which includes partially hydrolyzed fucoidan. The fucoidan may be sulfonated. The baby food composition may be in the form of a prepared food, a drink, a hard finger food, a soft finger food, or a cereal. Also disclosed is an infant formula composition including fucoidan, a protein, and a lipid. The fucoidan may be partially hydrolyzed, and also may be sulfonated. The protein may be derived from quinoa. Also disclosed are infant formula kits to be assembled in the field. The kits may include a substantially dehydrated infant formula composition and a diluting agent. The kit may alternatively include a ready-to-consume infant formula composition and substantially dehydrated additives which may be added to the formula before consumption. [FR] Cette invention concerne une composition d'aliment pour bébés conçue pour être consommée par un bébé et pour nourrir un bébé, laquelle composition contient du fucoïdane partiellement hydrolysé. Le fucoïdane peut être sulfoné. La composition d'aliment pour bébés peut se présenter sous la forme d'un aliment préparé, d'une boisson, d'un bâtonnet solide, d'un bâtonnet mou ou d'une céréale. La présente invention concerne également une composition de préparation pour jeunes enfants qui contient du fucoïdane, une protéine et un lipide. Le fucoïdane peut être partiellement hydrolysé et également sulfoné. La protéine peut provenir du quinoa. En outre, cette invention concerne des kits de préparations pour jeunes enfants à préparer soi-même. Ces kits peuvent éventuellement contenir une composition de préparation pour jeunes enfants prête à consommer et des additifs essentiellement déshydratés qui peuvent être ajoutés à la préparation avant consommation.

prenyltransferase with substrate flexibility from Morus alba, is demonstrated. Among the enzymatic products, 2-dimethylallyl-1,3,7-trihydroxyxanthone (3a) effectively attenuated glutamate-induced injury in SK-N-SH neuroblastoma cells. These results suggest a potential approach for the synthesis of bioactive prenylated xanthones by a substrate-relaxed flavonoid prenyltransferase.
