    Abstract: Methods and apparatus for facilitating the synthesis of compounds in a batch device are presented. Application of the batch type microfluidic devices to the synthesis of radiolabeled compounds is described. These methods and apparatus enable the selective introduction of multiple reagents via an enhanced rotary flow distribution valve through a single inlet port of the synthetic device. The sequential introduction of multiple reagents through a single inlet port allows an optimal delivery of highly concentrated reagents into the reactor and facilitates the synthesis of the desired products with a minimal loss of materials during transfers, which is critical to the synthesis of radiolabeled biomarkers.

  • 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: 7087571
    Abstract: The invention relates to a series of polyglycoside derivatives that contain water-soluble sulfosuccinate groups introduced into the molecule by reaction with the hydroxyl groups present in the starting polyglycoside molecule, with the chloro material. The preferred products have more than one water-soluble group per molecule and are made with mild reagents to avoid discoloration and mal odor. The most preferred products have between 2 and 3 functional groups per molecule.

  • Patent number: 7087709
    Abstract: Disclosed are novel polymers derivatized with at least one —NOx group per 1200 atomic mass unit of the polymer. X is one or two. In one embodiment, the polymer is an S-nitrosylated polymer and is prepared by reacting a polythiolated polymer with a nitrosylating agent under conditions suitable for nitrosylating free thiol groups. The polymers of the present invention can be used to coat medical devices to deliver nitric oxide in vivo to treatment sites.

  • 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: 7060685
    Abstract: Compounds and methods are provided for modulating in vitro and in vivo processes mediated by selectin binding. More specifically, selectin modulators and their use are described, wherein the selectin modulators that modulate (e.g., inhibit or enhance) a selectin-mediated function comprise a class of compounds termed BASAs (Benzyl Amino Sulfonic Acids, which include a portion or analogue thereof) linked to a carbohydrate or glycomimetic.

  • 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.
