    Abstract: A process is provided by which a polyrotaxane including cyclic molecules having a relatively long graft chain is easily obtained. Also provided is a polyrotaxane which includes cyclic molecules having a radical polymerization initiation site and is for use as a raw material in the process. The polyrotaxane comprises: a pseudo-polyrotaxane comprising cyclic molecules clathrated with a linear molecule, the cavities of the cyclic molecules having been pierced by the linear molecule; and blocking groups disposed respectively at both ends of the pseudo-polyrotaxane so as not to release the cyclic molecules. The cyclic molecules in the polyrotaxane have a radical polymerization initiation site.

  • Publication number: 20110098365
    Abstract: A method of preparing a salt product comprises the steps of: (i) providing a mixture which comprises salt dissolved in a solvent, said mixture further containing an organic material that is solid under ambient temperature conditions; and (ii) atomising said mixture and evaporating said solvent to produce a salt product comprised of particles of salt incorporating said organic material. The organic material may be a polymer such as a carbohydrate (e.g. maltodextrin or Gum Arabic). Novel salt products are disclosed which comprise hollow particles having a shell formed for individual crystallites of salt. The salt product is useful as a seasoning for food and may be used in lower amounts than conventional salt to provide the same taste. Particular advantages are obtained in the baking of bread.

    Abstract: Preparation of AT1 receptors antagonists formulations using the cyclodextrins, their derivatives and/or biodegradable polymers for the treatment of arterial hypertension, other cardiovascular disease and their complications. Until now, no applications using the AT11 receptor antagonists and cyclodextrins or derivatives and/or biodegradable polymers for the treatment of arterial hypertension, other cardiovascular diseases and their complications, was found in the technical state of art. The present invention is characterized by the combination of two different technologies: one is the molecular encapsulation of AT11 receptor antagonists in cyclodextrins and the other is the microencapsulation in biodegradable polymers. It also comprises the increase of the effectiveness of the AT11 receptor antagonists as well as an increase in their bio-availability.

  • Publication number: 20090312490
    Abstract: It is intended to provide a crosslinked polyrotaxane formed by crosslinking polyrotaxane molecules via chemical bonds which exhibits excellent optical properties in water or in an aqueous solution of sodium chloride; a compound having this crosslinked polyrotaxane; and a process for producing the same. The above object can be achieved by a crosslinked polyrotaxane having at least two polyrotaxane molecules, wherein linear molecules are included in a skewered-like state at the opening of cyclodextrin molecules and blocking groups are provided at both ends of the linear molecules, so as to prevent the cyclodextrin molecules from leaving, and cyclodextrin molecules in at least two polyrotaxane molecules being bonded to each other via chemical bond, characterized in that hydroxyl (—OH) groups in the cyclodextrin molecules are partly substituted with non-ionic groups.

  • Patent number: 7625878
    Abstract: A sulfoalkyl ether-alkyl ether cyclodextrin (SAE-AE-CD) derivative is provided. The SAE-AE-CD possesses advantages over known SAE-CD and AE-CD derivatives as well as over the parent cyclodextrin by being more water soluble and less membrane disturbing. The SAE-AE-CD includes at least one sulfoalkyl ether group and at least one alkyl ether group even though the degree of substitution for the functional groups can be different. The SAE functional group can be present in molar excess over the AE functional group and vice versa. The total degree of substitution of the cyclodextrin, with respect to both functional groups, can be varied such that a minority or a majority of the hydroxyl moieties of the CD are derivatized. The SAE-AE-CD derivative can be used to solubilize compounds with insufficient water solubility. In some cases, they also stabilize compounds in solution against degradation or to solubilize degradation products formed during degradation.

  • Patent number: 7595393
    Abstract: Disclosed are a method for the reduction of an oligosaccharide mixture and an oligosaccharide mixture prepared thereby. In accordance with the disclosed invention, a mixture of oligosaccharides having a given DP profile is reduced to a DE of essentially zero by catalytically hydrogenating the mixture under reaction conditions sufficient to preserve the DP profile of the mixture, which reaction conditions typically include a reaction temperature ranging from about 50° C. to about 150° C. and a reaction pressure ranging up to about 1500 psi. Surprisingly, when the mixture is a malto-oligosaccharide mixture, the reduced mixture will have a superior color-fastness and thermal stability as compared to a similar unreduced mixture of malto-oligosaccharides, and also low reactivity towards nitrogen-containing species.
