摘要:
The present invention relates to a method of synthesising sulforaphane by reacting a compound of formula (A) with an oxidizing agent in an aqueous solvent and in the presence of a catalyst. The invention further provides a method of synthesising a stabilised complex of sulforaphane and cyclodextrin by mixing the sulforaphane prepared by the methodology defined herein with cyclodextrin in an aqueous solvent.
摘要:
The invention concerns a method for producing a three-dimensional object, in particular an artificial tooth, by stereolithography wherein a liquid photocurable resin composition is cured by light. Said photocurable resin composition contains, based on the total weight of the photocurable resin composition, (i) from 90 to 99.9% by weight of a radical polymerizable organic compound (A) selected from radical polymerizable monomers, oligomers, pre-polymers and mixtures thereof; and (ii) from 0.1 to 10% by weight of a photosensitive radical polymerization initiator (B). Said radical polymerizable organic compound (A) comprises, based on the weight of the radical polymerizable organic compound (A), from 0.5 to 20% by weight of a polyrotaxane compound comprising a polymer chain selected from polyethylene glycol (PEG), polypropylene glycol (PPG), polyethylene glycol - polypropylene glycol (PEG- PPG) block copolymer or polydimethylsiloxane (PDMS), onto which the cyclodextrin ring(s) is/are slipped and wherein the cyclodextrin is derivatized with at least a radical polymerizable group. The invention also concerns a relative liquid photocurable resin composition and articles produced thereby.
摘要:
The present invention relates to compositions comprising fractionated alkylated cyclodextrm compositions having a single degree of substitution, and processes for preparing and using the same.
摘要:
A hydrogel product including a cross-linked polymer mixture of dextran cross-linked to hyaluronic acid, and one or more cyclodextrin molecules. The one or more cyclodextrin molecules are grafted onto the cross-linked polymer mixture, e.g. by amide bonds. The dextran may be cross-linked to the hyaluronic acid by ether bonds. The one or more cyclodextrin molecules may be grafted onto the cross-linked hyaluronic acid by amide bonds.
摘要:
The present invention aims to provide a polyrotaxane-containing composition having excellent transparency. The present invention relates to a polyrotaxane-containing composition including: a polyrotaxane that has a cyclic molecule, a linear molecule threading through a cavity of the cyclic molecule in a skewered manner, and capping groups capping both ends of the linear molecule; and an alkyl (meth) acrylate that has a C4-C18 alkyl group, the polyrotaxane having at least one cyclic molecule that has a C4-C18 alkyl group.
摘要:
An inclusion complex of an amorphous α-cyclodextrin, or derivative thereof, with encapsulated ethylene is provided by exposure of the dry solid amorphous α-cyclodextrin to ethylene gas under pressure. The inclusion complex will have applications in a number of fields including fruit ripening.
摘要:
Provided are inclusion complexes comprising fulvestrant and a cyclodextrin. The complexes may be useful for treating various conditions, such as cancer and systemic lupus crythematosus. Also provided are methods of producing the inclusion complexes, methods of using the inclusion complexes in therapy, and kits and unit dosages comprising the complexes.
