Abstract: Atropisomers of 3-substituted-4-arylquinolin-2-one derivatives having the general formula wherein R, R1, R2, R3, R4 and R5, are as defined herein, or a non-toxic pharmaceutically acceptable salt, solvate or prodrug thereof. The atropisomers can modulate the large conductance calcium-activated K+ channels and are useful in the treatment of disorders which are responsive to the opening of the potassium channels. In addition, the atropisomers can be stable, i.e., do not interconvert, for periods of up to one month, or more.

Abstract: Novel aminoalkylthiazole derivatives of Formula I are described which are openers of KCNQ potassium channels and are useful in the treatment of disorders responsive to the opening of the KCNQ potassium channels, including pain and migraine.

Abstract: This invention describes a process for preparing hydroxyazapirones of Formula I from azapirones of Formula II. The process comprises treating azapirones with a strong base, monitoring enolate formation of the azapirone by IR spectroscopy, and reacting the enolate with a source of molecular oxygen in the presence of a reductant. The process is suitable for large scale production of hydroxyazapirones.

Abstract: An analytical method and apparatus using principal component analysis of nuclear magnetic resonance (NMR) data for rapid molecular structure/function pattern recognition. The presence of a molecular substructure in an organic compound is determined by comparing principal components calculated from chemical shift values of the substructure in selected compounds with those calculated from the chemical shift values of the organic compound. Alternatively, principal components are calculated from the intensities of NMR signals for a full spectrum, or selected regions thereof, to determine whether an organic compound belongs to or is excluded from a set of structurally related compounds. Also, the presence of a pharmacophore in an organic compound can be determined by comparing the principal components derived from data on a set of compounds known to bind to a particular receptor, or have a common biological effect, with the principal components of the data set of the organic compound.
