Abstract: Substituted quinoxaline derivatives are useful for the prevention and/or treatment of medical conditions known as hyperproliferative diseases. The compounds are also useful for medical conditions that are affected by inhibiting 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase (PFKFB). Further, the compounds are useful for the prevention and/or treatment of cancer.
Abstract: The present invention relates to polymerizable compounds, to processes and intermediates for the preparation thereof, to liquid-crystal media comprising them, and to the use of the polymerizable compounds and liquid crystalline media for optical, electro-optical and electronic purposes, in particular in liquid crystalline displays, especially in liquid crystalline displays of the polymer sustained alignment type.
Abstract: The present invention relates to a process for improving the solubility or dissolution behaviour of components in an aqueous solution. The dissolution properties of a slowly/badly dissolving component can be positively affected by generating mixed particles of this component with another component which has a negative dissolution enthalpy. By preparing and adding such mixed particles solubility is improved without changing the chemical composition.
