Abstract: The present invention relates to improved processes for preparing lactam morphinans. The processes generally transform keto-morphinans to seven-membered lactam morphinans using a hydroxyamine sulfonic acid reagent and proceed in high yield and with good selectivity.
Abstract: In certain embodiments, a syringe mount of the invention may include a plate, an actuator, and one or more movable members located between the plate and the actuator. Each of the plate and the actuator may have an orifice defined therein, and an imaginary reference axis of the syringe mount may extend through one or both of these orifices. The actuator may be movable relative to the plate in a direction substantially perpendicular to the reference axis. Further, the moveable member(s) may be designed to move (e.g., pivot) toward the reference axis due to movement of the actuator from a first position to a second position and to move (e.g., pivot) away from the reference axis due to movement of the actuator from the second position to the first position.
Abstract: The present invention provides an efficient process for the preparation of hexahydroisoquinolines from amides. In particular, the invention provides a good yielding, one-pot process for the synthesis of hexahydroisoquinolines.

Abstract: An apparatus and method of operation is provided for a contrast media injector having a powered drive ram. The drive ram is designed to interface with a plunger of a syringe in order to move the plunger forward and backward relative to a barrel of the syringe. The syringe, having an RF data tag associated therewith, is mounted on to the contrast media injector. Electromagnetic signals are transmitted from an electromagnetic device of the injector in response to mounting the syringe. Data is electromagnetically read from the RF data tag of the syringe using the electromagnetic device of the injector. The transmitting is terminated after the electromagnetically reading. Medical fluid is then dispensed from the syringe. Electromagnetic signals are transmitted from the electromagnetic device in response to initiation of the dispensing. Data is electromagnetically written to the RF data tag of the syringe using the electromagnetic device of the injector.

Abstract: The present invention is directed to processes for the synthesis of morphinans. In particular, a process for coupling a carboxylic acid compound with an amine compound to form an amide product that can then be isolated or the crude amide product can be cyclized to form a 3,4-dihydroisoquinoline. In one embodiment, the carboxylic acid contains a phenol moiety protected with a labile protecting group. The protected phenol reduces reaction times, simplifies work-up of the product, and reduces the amount of cyclizing agent, POCl3 that is necessary to form the 3,4-dihydroisoquinoline.

Abstract: The present invention is directed to control of medical fluid injection systems. For instance, in some embodiments, an injection protocol may be initiated, and an actual flow rate of the medical fluid utilized in the injection protocol may be adjusted based, at least in part, on an inherent system elasticity of the injection system.
Abstract: The present invention provides methods for delivery of therapeutic agents to a subject using multi-component liposomal systems. The methods include administration of a therapeutic liposome containing an active agent, followed by a administration of an attacking liposome that induces release of the agents from the therapeutic liposome.

Abstract: An injection system (108) includes a sterilization port (130) operable to sterilize a tube set connector (116) inserted therein. The sterilization port (130) may include a single sterilization port opening (132) through which the tube set connector (116), in an unconnected state, may be inserted. The sterilization port (130) may include an ultraviolet light source (158) capable of irradiating the tube set connector (116) with ultraviolet radiation when the tube set connector (116) is disposed within the sterilization port (130). The sterilization port (130) may include a movable member or door (136) capable of closing around the inserted tube set connector (116) and/or a tubing (118) connected to the tube set connector (116) to reduce the amount of ultraviolet light that may escape from the sterilization port (130). A sensor (194) may be included to determine if the tube set connector (116) has been inserted into the sterilization port (130).
Abstract: The invention provides a process for the N-alkylation of normorphinan compounds to produce N-alkylated morphinan compounds. In particular, the process relates to the alkylation of a normorphinan compound by a carboxaldehyde in the presence of a reducing agent to form an N-alkylated morphinan.
