Selectiveinhibitors of neuronalnitricoxidesynthase (nNOS) are regarded as valuable and powerful agents with therapeutic potential for the treatment of chronic neurodegenerative pathologies and human melanoma. Here, we describe a novel hybrid strategy that combines the pharmacokinetically promising thiophene-2-carboximidamide fragment and structural features of our previously reported potent and

Symmetrische und asymmetrische Disazoverbindungen der Formel
worin R1 gleich oder verschieden ist und Wasserstoff, Chlor oder Brom, Methyl oder Methoxy bedeutet, R2, das gleich oder verschieden ist, entweder Wasserstoff oder wenn das dem gleichen Ringsystem zugehörige R1 Wasserstoff ist, auch Methyl oder Äthyl ist, und n 1-4 ist, und deren Gemische werden erhalten, wenn man ein Diamin der Formel
bisdiazotiert und auf eine oder mehrere Kupplungskomponenten der Formel
kuppelt. Die Verbindungen eignen sich als Farbmittel, insbesondere zum Pigmentieren von hochmolekularem organischem Material.
A process for producing an aryl carbamate of a high purity at a high yield by reacting a diaryl carbonate with an amine compound having one or more hydrogen atoms bonded to the N position in the presence of carboxylic acid(s) of the following general formulae (I): R1-COOH and/or (II): R2-COOH (wherein R1 represents an alkyl or cycloalkyl group having a carbon atom at the α-position, which is bonded to only one hydrogen atom, and R2 represents an alkyl group having a carbon atom at the α-position, which is not bonded to a hydrogen atom).
A polyimide composition and a process to prepare polyimide resins with reduced plate out and mold deposits is described. During resin molding operations the low plate out resins show a longer period of operation between cleaning of equipment leading to more efficient operation.
