Abstract:
Transporters are an emerging target family with enormous potential, offering scientific and economic opportunities. The sodium/calcium exchanger is an important mechanism for removing Ca 2+ from diverse cells. In heart, it extrudes Ca 2+ that has entered through Ca 2+ Channels to initiate contraction, while Na + enters the heart cell. It is of considerable interest to identify Compounds that modulate the activity of sodium/calcium exchangers. The present invention is directed to a fluorescence-based assay for detecting NCX and NCKX "forward mode" modulating Compounds. It further refers to a kit of parts comprising cells expriming a sodium/calcium exchanger and the use of the kit of parts to test a Compound for activity as an agonist or antagonist of a sodium/calcium exchanger.
Abstract:
The present invention refers to a method for determining the activity of the organic cation transporter (OCT), a method for determining the activity of or identifying a chemical compound that modulates the activity of OCT with the help of a cell free electrophysiological sensor chip containing a solid-supported sensor electrode and a lipid layer containing the OCT located in the immediate spatial vicinity to the sensor electrode, whereas the sensor electrode is electrically insulated relative to the solutions used and to the lipid layer, as well as to the sensor chip itself and a kit containing same.

Transporteure sind eine aufstrebende Zielfamilie mit enormem Potential, welche wissenschaftliche und wirtschaftliche Möglichkeiten bieten. Der Natrium/Calcium- Austauscher ist ein wichtiger Mechanismus für das Entfernen von Ca 2+ aus diversen Zellen. Im Herz extrudiert er Ca 2+ , welches durch Ca 2+ -Kanäle zum Initiieren von Kontraktion eingetreten ist, während Na + in die Herzzelle eintritt. Es ist von erheblichem Interesse, Verbindungen zu identifizieren, welche die Aktivität des Natrium-Calcium-Austauschers modulieren. Die vorliegende Erfindung ist ausgerichtet auf ein Fluoreszenz-basiertes Assay für das Erkennen von Verbindungen zum Modulieren des NCX im „Vorwärtsmodus". Sie betrifft ferner einen Teilesatz umfassend Zellen, welche NCX exprimieren, und die Verwendung des Teilesatzes zum Testen einer Verbindung auf die Aktivität als ein Agonist oder Antagonist von NCX.
Abstract:
The present invention relates to di(hetero)arylcyclohexane derivatives of the formula (I), in which Ar 1 , Ar 2 , R 1 and R 2 have the meanings indicated in the claims. The compounds of the formula (I) are valuable pharmaceutical active compounds which inhibit ATP-sensitive potassium channels in the heart muscle and are suitable, for example, for the treatment of disorders of the cardiovascular system such as arrhythmias or a decreased contractility of the heart, such as can occur, for example, in coronary heart disease, cardiac insufficiency or cardiomyopathies. In particular, they are suitable for the prevention of sudden cardiac death. The invention furthermore relates to processes and intermediates for the preparation of the compounds of the formula (I), their use and pharmaceutical compositions comprising them.
