Description
In Vitro
LUF7244 (0-10 μM; HEK293 cells) binds Kv11.1 channels and increases IKv11.1 by inhibiting inactivation in a dose-dependent manner[1].
LUF7244 (0-10 μM; cardiomyocytes) reduces action potential duration (APD) by approximately 50% and dofetilide-induced early afterdepolarization (EAD) in isolated ventricular CMCs from SR and CAVB dogs[1].
LUF7244 (10 μM) had no effects on IKIR2.1, INav1.5, ICa-L, and IKs but doubled IKr[1].

Cardiac voltage-sensitive optical mapping
Cardiac voltage-sensitive optical mapping records changes in transmembrane potential from cardiac tissue by staining the preparation with a voltage-sensitive dye and imaging fluorescence changes during electrical activation; the resulting optical action potentials can be used to map activation time, action potential duration, conduction velocity, wavefront propagation, and arrhythmia dynamics. The optical signal represents a relative fluorescence change from a tissue volume rather than a single-cell intracellular recording, so spatial resolution, sampling rate, voltage resolution, optical magnification, light penetration, and motion control must be considered together when interpreting optical action potentials.
