摘要:The syntheses and in vitro antitumor properties of carbamate-containing, dicarbamate-containing, and ureido-containing phospholipid compounds that have an ether linkage at the C-1 position of a glycerol backbone, a carbamate, dicarbamate, or ureido moiety at the C-2 position of the glycerol backbone, and a phosphocholine, phosphonocholine, or glycoside moiety at the C-3 position of the glycerol backbone are described. The synthesis and antiproliferative activity of ether lipids with a naphthol moiety at the C-1 position are also described. These compounds were shown to be potent inhibitors of cancer cell growth. These compounds are useful for killing cancer cells and treating 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.

摘要:Galactosylhydroxylysine is a terminal degradation product of the bone matrix which thus serves as biochemical marker of bone resorption. A method of synthesizing galactosylhydroxylysine is provided. Antibodies against this synthetically prepared galactosylhydroxylysine conjugated to protein carriers were raised to establish methods to measure galactosylhydroxylysine in biological fluids. The antibodies of the invention recognize native galactosylhydroxylysine and are, for example, useful in the measurement of galactosylhydroxylysine as a biochemical marker of bone resorption in biological fluids. Testing of human serum or adolescent urine resulted in dose-dependent increases in signal intensity using the method of the invention.

标 题 :Synthesis of glycodendrimer reagents
发明人：DAVIS BENJAMIN G; JONES JOHN BRYAN; BOTT RICHARD R
权利人:GENENCOR INT
摘要:The present invention relates to a chemically modified mutant protein including a cysteine residue substituted for a residue other than cysteine n a precursor protein, the substituted cysteine residue being subsequently modified by reacting the cysteine residue with a glycosylated thiosulfonate. Also a method of producing the chemically modified mutant protein is provided. The present invention also relates to a glycosylated methanethiosulfonate. Another aspect of the present invention is a method of modifying the functional characteristics of a protein including providing a protein and reacting the protein with a glycosylated methanethiosulfonate reagent under conditions effective to produce a glycoprotein with altered functional characteristics as compared to the protein. In addition, the present invention relates to methods of determining the structure-function relationships of chemically modified mutant proteins. The present invention also relates to synthetic methods for producing thio-glycoses, the thio-glycoses so produced, and to methods for producing glycodendrimer reagents.
