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在受试者中诱导心脏毒性能力的测定、方法和试剂盒。特别地,本发明涉及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。所述的测定、方法和试剂盒利用新型荧光示踪剂与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。
