A test fixture for a printed circuit board (PCB) assembly (6) includes lower and upper units (2, 4). The PCB assembly includes a PCB (60) defining two spaced positioning holes (62), and a reinforcing plate (64) defining a plurality of openings (65). The lower unit includes a fixed base (20) and an adjustable support plate (21) defining a plurality of through holes (27). The upper unit includes a movable base (40), and a test plate (41) having two rows of identical columns (44) for engaging with the support plate. The support plate includes first and second positioning members (24, 25) supporting the PCB assembly. Support posts (272) are arranged on the fixed base for supporting a bottom of the PCB. The test plate includes two positioning pins (45) engaging in the positioning holes of the PCB, and a plurality of pressing posts (46) for pressing a top of the PCB.

Novel heterocyclic dihydropyrimidine compounds useful as inhibitors of potassium channel function (especially inhibitors of the Kv1 subfamily of voltage gated K+ channels, especially inhibitors Kv1.5 which has been linked to the ultra-rapidly activating delayed rectifier K+ current IKur), methods of using such compounds in the prevention and treatment of arrhythmia and IKur-associated conditions, and pharmaceutical compositions containing such compounds.
摘要:
A process is provided for preparing novel crystalline forms, namely selectively and consistently preparing the H2-1 dihydrate crystalline form, the H2-2 dihydrate crystalline form, the N-3 anhydrate crystalline form and the MTBE solvate crystalline form of the IKur compound (2S)-1-[[(7R)-7-(3,4-dichlorophenyl)-4,7-dihydro-5-methylpyrazolo[1,5]pyrimidine-6-yl]carbonyl]-2-(4-fluorophenyl)pyrrolidine. The process includes preparation of the H2-1 and H2-2 forms which are used in preparing the N-3 anhydrate form which is particularly stable and has suitable flow properties and desired particle size. Novel H2-1 dihydrate and H2-2 dihydrate forms, the N-3 anhydrate form and the MTBE solvate form of the above IKur compound, pharmaceutical compositions containing such novel forms and a method for preventing or treating arrhythmias including atrial fibrillation and IKur related conditions employing such novel forms are also provided.

摘要:
A tester includes a base (10) including a top wall (12) and a control panel (18), a cover (30) pivotably attached to the base, a pair of master cylinders (40) connecting the base with the cover, a holding fixture including a lower unit (50) and an upper unit (70), and a first testing unit. A plurality of first positioning members (54) is formed on the lower unit for supporting a printed circuit board assembly including a printed circuit board (PCB) (80). A plurality of pressing post (76) depends from the upper unit for pressing the PCB, and a plurality of support posts (127) is formed on the top wall for extension through the lower unit to support the PCB. The control panel controls the master cylinders to open and close the cover, and controls the first testing unit to adjustably insert in ports of the PCB for test.
