  • Patent number: 8361998
    Abstract: The invention relates to compounds according to Formula I: or a pharmaceutically acceptable salt thereof, wherein m, n, R1, R2, R3, R4, R5, x and y are as defined herein. Compounds according to Formula I are pharmacologically effective as potassium channel inhibitors, in particular inhibitors of the acetylcholine operated inward rectifying potassium channel current (i.e. IKACh blockers), and are believed to be useful in the treatment of cardiac arrhythmias, in particular supraventricular tacharrhythmias, such as atrial fibrillation and atrial flutter.

  • Patent number: 6841559
    Abstract: Novel pyridinones and their derivatives which are effective in treating or preventing Gram-negative bacterial infections are provided. The pyridinones are stable and easily derivatized; the methods by which these derivatizations occur is described. Two regioselective and functional group tolerant methods for the synthesis of the novel pyridinones are also provided. One such synthetic method involves reacting an imine and a Meldrum's acid derivative in solution. The other synthetic method is a solid phase synthesis of the pyridinones in which an imine is prepared bound to a solid support and a Meldrum's acid derivative is reacted with the imine. Novel imine intermediates useful in the solid phase and solution methods of synthesizing the pyridionones are also described.
