Abstract:
Provided are a stationary phase and a column using a cucurbituril-bound silica gel, and a method of separating taxane using the column. The taxane separation method includes: preparing a column for taxane separation, the column being packed with a stationary phase including a cucurbituril-bound silica gel in which a cucurbituril represented by Formula 1 or 2 is covalently bound to a modified silica gel represented by Formula 3; dissolving a taxane powder in a solvent to prepare a taxane-containing solution; applying the taxane-containing solution to the column; supplying a mobile-phase solvent to the column to obtain a taxane extract from the column; and purifying taxane from the taxane extract. Therefore, highly purified taxane can be separated from a low-purity crude taxane extract.

Abstract:
Provided is a gel comprising cucurbituril which is prepared by various methods, and is able to include various compounds and prepare a gel including medicines and a gel capable of being converted into sol by the external stimulation according to the property of molecules contained in the gel. The gel comprises a compound represented by the formula(1). In the formula(1), n is an integer from 4 to 20, and each A1 and A2 is independently H, OR, SR, or NHR, wherein R is substituted or unsubstituted C1-30 alkyl, substituted or unsubstituted C2-30 alkenyl, substituted or unsubstituted C2-30 alkynyl, substituted or unsubstituted C2-30 carbonylalkyl, substituted or unsubstituted C1-30 thioalkyl, substituted or unsubstituted C1-30 alkylthiol, substituted or unsubstituted C1-30 hydroxyalkyl, substituted or unsubstituted C1-30 alkylsilyl, substituted or unsubstituted C1-30 aminoalkyl, substituted or unsubstituted C1-30 amino alkylthioalkyl, substituted or unsubstituted C5-30 cycloalkyl, substituted or unsubstituted C2-30 heterocycloalkyl, substituted or unsubstituted C6-30 aryl, substituted or unsubstituted C6-20 arylalkyl, substituted or unsubstituted C4-30 heteroaryl, and substituted or unsubstituted C4-30 heteroarylalkyl. The method for preparing the gel comprises the steps of: (a) dissolving the compound of the formula(1) in a solvent to prepare a sol; (b) adding a pharmacologically active ingredient to the sol; and (c) converting the pharmacologically active ingredient added sol into a gel.
