摘要:
An oxylamino group-containing compound represented by the following formula: R1—B-A-B—R2, wherein R1 represents a polymerizable group, R2 represents an oxylamino group-containing group or an oxylamino derivative-containing group, B represents an ester linkage or an amide linkage, and A represents an optionally substituted alkylene group having 2 to 12 carbon atoms.
摘要:
A novel azasugar derivative, and a drug containing the same as an active ingredient are disclosed. The drug is useful for treatment of keratinocyte-proliferative diseases.
摘要:
Galactosylceramide analogues represented by the following formula (1) or (2). (wherein X and Y each represent S or O, R1 and R2 each represent an alkyl group or an alkenyl group each having 9 to 35 carbon atoms. R3 represents an alkyl group or an alkenyl group each having 2 to 30 carbon atoms.) It is provided a β-glucocerebrosidase activator which is easily available, and external skin preparations and a method of activating β-glucocerebrosidase, in which improvement in formation of horny layer transmission barrier is expected by activating β-glucocerebrosidase so that an improved effect in rough skin is also expected.
摘要:
The present invention provides a sugar chain purification instrument which can continuously and efficiently purify the sugar chain. According to the present invention, the instrument includes an immobilized protease column in which a carrier which can be packed in the column and on which protease is immobilized is packed and an immobilized glycopeptidase column in which a carrier which can be packed in the column and on which glycopeptidase is immobilized is packed, these columns being connected in series, and the reaction is carried out while continuously passing a glycoprotein to be decomposed together with a suitable buffer solution through the above columns. The step of liberation of sugar chain from the glycoprotein is highly simplified and labor-saving, and liberation of the sugar chain can be moderately and simply performed.
摘要:
The present invention provides a method for preparing a sample characterized by binding a substance A containing a hydrazide group to a sugar chain and/or a sugar derivative via hydrazone formation between the hydrazide group of the substance A and the reducing end of the sugar chain and/or the sugar derivative thereby to enable the separation and purification of the sugar chain and/or the sugar derivative for an analytical sample from a biological sample containing the sugar chain and/or the sugar derivative by a simple operation.
摘要:
The present invention provides substance which can specifically interact with sugar chains. Further, the present invention provides a method for separating, concentrating, or purifying sugar chains or a sugar chain-containing substance in a sample, comprising the steps of: a) contacting a sugar chain-trapping carrier comprising a substance which can specifically interact with sugar chains with the sample in a fluid phase under conditions that the sugar chain-trapping carrier can react with the sugar chains or sugar chain-containing substance; b) isolating a composite of the sugar chain-trapping carrier and the sugar chains or sugar chain-containing substance from the fluid phase; and c) exposing the composite to the conditions that the interaction between the sugar chain-trapping carrier and the sugar chains or sugar chain-containing substance is at least partially eliminated.
