摘要:An isolated or recombinant MYB polypeptide having activity as a transcription factor in the synthesis of proanthocyanidins in plants, and nucleic acid molecule encoding same, wherein the polypeptide activates in the plants (a) promoters of the leucoanthocyanidin (LAR) and anthocyanidid reductase (ANR) genes, and (b) promoters of at least two of the genes of the general flavonoid pathway. Use of the polypeptide and nucleic acid molecule in regulating the biosynthesis and accumulation of proanthocyanidins in plants, such as in modifying pasture quality of legumes, is also disclosed.

摘要:A process of extraction of anthocyanins from different foodstuffs or by-products, and their conversion into pyranoanthocyanins compounds, which can be used as pigments having new colors and improved stability to be incorporated into skincare formulations in particular anti-ageing and sun-protection formulations. Cosmetic formulations having the pigments with improved properties of UV protection and moisturizing, anti-dark spots, anti-wrinkles and wound-healing, which can be associated with interesting colors ranging from red to blue depending on the selected pigments in the composition and in the formula composition. The present invention is in the area of organic chemistry, biochemistry, pharmacology and cosmetics for skincare.

标 题 :Preparation of prodrugs for selective drug delivery
发明人：MILLS RANDELL L; WU GUO-ZHANG
摘要:Synthesis of a chemical compound having the formula A-B-C that may serve for applications such as drug delivery where A is a chemiluminescent, moiety, B is a photochromic moiety, and C is a biologically active moiety where A-B-C may serve as a prodrug. Novel synthetic methods of the present invention to form the prodrug comprised the steps of (1) forming a benzophenone, (2) forming a diaryl ethylene, (3) attaching a phthalimide moiety to at least one of the aryl groups of the ethylene to form a phthalimide-ethylene conjugate, (4) condensing two ethylene-phthalimide conjugates to form a phthalimide-pentadiene conjugate, (5) converting the phthalimide to the phthalhydrazide by reaction with hydrazine to form a carrier compound according to the present invention, and (6) reacting the carrier compound with an nucleophilic moiety of the drug to form the corresponding prodrug. Alternatively the carrier can be prepared by using the halo-substituted diaryl ethylene to make the corresponding cationic leuco dye-like compound with known methods. The cationic compound then is protected by reacting with a nucleophile and coupled with the aminophathalimide by palladium-catalyzed amination to form the protected phthalimide-pentadiene conjugate. The latter is refluxed with hydrazine to convert its phthalimide to the phthalhydrazide and acidified to give the carrier. An additional aspect of the present invention relates to the use of these compounds as antiviral agents for the treatment of viral infections such as HIV and as anticancer agents for the treatment of cancers such as bowel, lung, and breast cancer.

标题:Method for the synthesis of anthocyanins
发明人：BAKSTAD EINAR
权利人:BAKSTAD EINAR; BIOSYNTH AS
摘要:The present invention relates to methods of preparing anthocyanins, and methods of preparing precursors of anthocyanins. The methods utilize a coupling reaction between a sugar and a suitable electrophilic precursor to form Eastern half intermediates that are then reacted with Western half intermediates to form the target anthocyanins. Some Eastern half intermediates and electrophilic precursors also form part of the invention.
