Abstract:
PROBLEM TO BE SOLVED: To provide a methods, an apparatus, and a system for performing a high-throughput preparation and a screening of salts and polymorphs of drug candidates. SOLUTION: The method is directed toward enhancing the pre-formulation discovery process used for a drug development. In particular, processes of determining suitable salts and processes of discovering substantially every polymorph that can form from a particular drug candidate are provided. The processes are performed using several apparatuses that are specifically configured to carry-out various steps in a high-throughput characterization process. One such apparatus is configured for synthesizing a plurality of library members from, for example, a library model generated by a computer system. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a parallel reactor system suitable for the handling of fluid substances containing slurry substance and to provide a method concerning the same. SOLUTION: The parallel reactor system is provided with a reactor 9, a vessel to be placed in the reactor and holding a reaction mixture and a cannula for introducing fluid reaction substances to the vessel. A robot system 23 enables the operation of inserting the cannula into a cannula path in the reactor 9 for conveying the reactant containing the slurry to a corresponding vessel and pulling off the cannula from the cannula path after the conveyance. The related method and the cannula design are also disclosed.
Abstract:
A method of preparing and delivering a slurry into a series of vessels in a reactor, said method comprising: (1) mixing a particulate solid material and a liquid dispersing medium and agitating the mixture to form a substantially homogeneous first slurry in which said particulate solid material is suspended in the liquid; (2) aspirating said first slurry into a cannula carried by a robot system while the slurry is substantially homogeneous; (3) operating the robot system to insert the cannula into the reactor;(4) delivering the slurry from the cannula into the vessel while the cannula is in said reactor; and (5) repeating (2)-(4) for a second vessel with said first slurry or repeating (2)-(4) for a second vessel with a second slurry.
Abstract:
A parallel reactor system including a reactor and vessels in the reactor for holding reaction mixtures, and a cannula for introducing fluid reaction material into the vessels. A robot system is operable to insert the cannula into cannula passages in the reactor for delivery of reaction materials, including slurries, to respective vessels, and to withdraw the cannula from the cannula passages after delivery. Related methods and cannula designs are also disclosed.

Abstract:
An apparatus and method for synthesis and screening of materials are disclosed. According to one aspect of the present invention, a parallel batch reactor for effecting chemical reactions includes a pressure chamber, an inlet port, two or more reaction vessels within the pressure chamber, and a reaction vessel cover. The inlet port is in fluid communication with the pressure chamber, and pressurizes the pressure chamber from an external pressure source. Each of the two or more reaction vessels are in isolatable fluid communication with the pressure chamber such that during a first pressurizing stage of operation, each of the two or more reaction vessels can be simultaneously pressurized through common fluid communication with the pressure chamber. In addition, during at least a second reaction stage of operation, each of the two or more pressurized reaction vessels can be isolated from each other by positioning the reaction vessel cover appropriately.
Abstract:
A combinatorial chemistry reactor system for the parallel processing of reaction mixtures. The system comprises a frame, a head mounted in fixed position on the frame, and a reactor block having a plurality of wells therein for containing reaction mixtures. The reactor block is movable with respect to the head between a first position in which the reactor block and head are assembled for conducting reactions in the wells and a second position in which the reactor block is removed from the head for providing access to the vessels. Gaps in the reactor block between the wells serve to thermally isolate the wells from one another. Other features relating to pressure relief, reactor block temperature control, and sensor mounting are also disclosed.
