Disclosed are assays, methods, and kits for the screening of test compounds for their capability to induce cardiotoxicity in a subject. In particular, whether a test compound has the effect to prolong the Q-T interval as measured by an electrocardiogram in a human. The assays, methods, and kits disclosed herein make use of the binding interaction between novel fluorescent tracers and the hERG K+ channel, and the propensity of a test compound to influence that binding interaction.
本发明涉及用于筛选试验化合物是否能够在受试者中引起心脏毒性的测定方法和工具包。特别地,本发明揭示了一种测试化合物是否具有在人体中通过心电图测量延长Q-T间期的效果的方法。所述测定方法和工具包利用了新型荧光示踪剂与hERG K+通道之间的结合相互作用以及测试化合物影响该结合相互作用的倾向。
