  • Patent number: 10626083
    Abstract: A method of manufacturing 2-(1-{6-[(2-[F-18]fluoroethyl)(methyl)amino]-2-naphthyl}ethylidene)-malononitrile ([F-18]FDDNP) utilizes a semi-automated module that is used to perform fluorination, pre-purification, separation, product extraction, and formulation. The method is able to produce [F-18]FDDNP with high yields and ready for human administration under existing FDA regulations, and without the need for hazardous organic solvents such as dichloromethane (DCM), methanol (MeOH), and tetrahydrofuran (THF). The method also improves the speed with which [F-18]FDDNP can be synthesized with the method being able to generate a final product within about 90 to 100 minutes. This synthesis method is easily adaptable to FDA registered and approved automated synthesis systems.

  • Patent number: 9481705
    Abstract: A modular chemical production system includes multiple modules for performing a chemical reaction, particularly of radiochemical compounds, from a remote location. One embodiment comprises a reaction vessel including a moveable heat source with the position thereof relative to the reaction vessel being controllable from a remote position. Alternatively the heat source may be fixed in location and the reaction vial is moveable into and out of the heat source. The reaction vessel has one or more sealing plugs, the positioning of which in relationship to the reaction vessel is controllable from a remote position. Also the one or more reaction vessel sealing plugs can include one or more conduits there through for delivery of reactants, gases at atmospheric or an elevated pressure, inert gases, drawing a vacuum and removal of reaction end products to and from the reaction vial, the reaction vial with sealing plug in position being operable at elevated pressures.

  • Publication number: 20140248212
    Abstract: Embodiments of the invention include a PET/SPECT reporter gene system that uses enhanced non-immunogenic versions of a human mitochondrial thymidine kinase 2 expressed in cytoplasm to preferentially trap novel PET/SPECT radiolabeled L and D-enantiomer analogs of the natural substrate thymidine. Such highly sensitive, non-immunogenic reporter genes function in combination with a set of novel, radiolabeled probes in whole body molecular imaging applications using positron emission tomography (PET) or single photon emission computed tomography (SPECT).

  • Patent number: 8742139
    Abstract: Phenyliodonium ylide derivatives substituted with electron donating as well as electron withdrawing groups on the aromatic ring are shown for use as precursors in aromatic nucleophilic substitution reactions. The iodonium ylide group is substituted by nucleophiles such as halide ions to provide the corresponding haloaryl derivatives. No-carrier-added [F-18]fluoride ion exclusively substitutes the iodonium ylide moiety in these derivatives and provides high specific activity F-18 labeled fluoro derivatives. Protected L-dopa-6-iodonium ylide derivative have been synthesized as a precursors for the preparation of no-carrier-added 6-[F-18]fluoro-L-dopa. The iodonium ylide group in this L-dopa.derivative is nucleophilically substituted by no-carrier-added [F-18]fluoride ion to provide a [F-18]fluoro intermediates which upon acid hydrolysis yielded 6-[F-18]fluoro-L-dopa.

  • Patent number: 8674101
    Abstract: Iodylbenzene derivatives substituted with electron donating as well as electron withdrawing groups on the aromatic ring are used as precursors in aromatic nucleophilic substitution reactions. The iodyl group (IO2) is regiospecifically substituted by nucleophilic fluoride to provide the corresponding fluoroaryl derivatives. No-carrier-added [F-18]fluoride ion derived from anhydrous [F-18](F/Kryptofix, [F-18]CsF or a quaternary ammonium fluoride (e.g., Me4NF, Et4NF, n-Bu4NF, (PhCH2)4NF) exclusively substitutes the iodyl moiety in these derivatives and provides high specific activity F-18 labeled fluoroaryl analogs. Iodyl derivatives of a benzothiazole analog and 6-iodyl-L-dopa derivatives have been synthesized as precursors and have been used in the preparation of no-carrier-added [F-18]fluorobenzothiazole as well as 6-[F-18]fluoro-L-dopa.
