  • Publication number: 20090130155
    Abstract: The present invention provides a formulation characterised by the simultaneous presence in cyclodextrin based supramolecular complexes, of two components, one of which possesses insecticidal, acaricidal, fungicidal, snailcidal or vermicidal activity and the other possesses an activity synergistic with the first, enhancing its effectiveness. The biologically active substance is chosen from the following classes of chemical products: carbamates, organophosphates, thioureas, pentatomic or hexatomic heterocycles in which 1, 2 or 3 nitrogen atoms are present. The synergistic substance can be chosen from components containing at least one aromatic or non aromatic carbocyclic ring, such as piperonyl butoxide, sesamol, verbutin or MGK 264. For the same dose, the activity of the present formulations is greater than that of the mixture of the two active components alone or separately complexed with cyclodextrin.

  • Patent number: 7163931
    Abstract: Pharmaceutical compositions comprising low doses of sensitive complexes between an estrogen and a cyclodextrin are provided with improved stability. In specific embodiments the composition comprises a complex between ethinyl estradiol and ?-cyclodextrin in a granulate preparation and in yet another embodiment the composition comprises a limited amount of polyvinylpyrrolidone since this excipient was found to degrade ethinyl estradiol. Furthermore, a method for improving the stability of an estrogen in a composition and for manufacturing such a stable composition is provided. Essentially, the granulate preparation are manufactured under careful control of the relative humidity.

  • Patent number: 7115586
    Abstract: The invention provides a number of methods for enhancing the aqueous solubility of an active ingredient which is insoluble or sparingly soluble in water. In one preferred embodiment, solubilization of the active ingredient is enhanced by combining it with ?-cyclodextrin in an aqueous complexation medium comprising ?-cyclodextrin and a negatively- or positively-charged compound which forms an inclusion or non-inclusion complex with ?-cyclodextrin and its inclusion complexes.

  • Patent number: 7109324
    Abstract: A process for chemically bonding an odor-encapsulating agent to textiles includes reacting a cyclodextrin with a cross-linking agent capable of forming ether bonds with the cyclodextrin and with the textile material, and curing the textile material treated with a mixture of the cyclodextrin and cross-linking agent. Preferably, the cross-linking agent is imidazolidone, which forms an ether bond with a hydroxyl group on the cyclodextrin and with a hydroxyl group. In textile materials containing cellulose, imidazolidone forms an ether bond with a hydroxyl group on the cellulose. An active agent can be complexed with the cyclodextrin for release. Textiles formed by such a process can comprise an article of clothing adapted to trap odors emanating from a wearer.

  • Patent number: 7091335
    Abstract: Disclosed are derivatized malto-oligosaccharides and methods for the preparation thereof. In accordance with the disclosed invention, a malto-oligosaccharide is hydrogenated to thereby obtain a hydrogenated malto-oligosaccharide, and the resulting hydrogenated malto-oligosaccharide is derivatized, such as via oxidation, esterification, etherification, or enzymatic modification. The derivatization of such hydrogenated malto-oligosaccharides results in a surprisingly low level of a formation of by-products and products of degradation. In a particularly preferred embodiment of the invention, a mixture of malto-oligosaccharides is catalytically hydrogenated under reaction conditions suitable to substantially preserve the degree of polymerization (DP) profile of the mixture. The resulting malto-oligosaccharide mixture then is derivatized to form a derivatized malto-oligosaccharide mixture.

  • Patent number: 7084132
    Abstract: A stable form of artemisinin wherein an artelinic acid or artesunic acid is complexed with cyclodextrin analogs, preferably, ?-cyclodextrin. The complexed cyclodextrin artemisinin formulation shields the peroxide portion of the artemisinin backbone from hydrolytic decomposition rendering it stable in solution. Artelinic acid and cyclodextrin are placed into contact with one another to yield a 2:1 molecular species. Artesunic acid and cyclodextrin yield a 1:1 molecular species. The complexed cyclodextrin artemisinin formulation is effective for the treatment of malaria and is stable in solution for long periods of time.

  • Patent number: 7030237
    Abstract: In a reaction system having at least two liquid-liquid interfaces between an organic phase of raw material containing a compound(s) to be separated and an aqueous phase of an aqueous solution of inclusion-complexing agent and between that aqueous phase and an organic phase(s) of extraction solvent(s), the compound(s) to be separated is entrapped into the aqueous phase through formation of an inclusion complex(es) of the inclusion-complexing agent with the compound(s), while the compound(s) is entrapped into the organic phase(s) of extraction solvent(s) through dissociation of said inclusion complex(es). The foregoing operation is performed using, for example, a squarish U-shaped tube or an H-shaped tube with bottom plates. Preferred examples of inclusion-complexing agent include highly water-soluble branched cyclodextrins.
