In Vitro	Latrunculin B displays growth inhibition of HeLa cells with an IC50 value of 1.4 μM[1]. Latrunculin B modulates electrophysiological characteristics and arrhythmogenesis in pulmonary vein cardiomyocytes. Latrunculin B (100 nM) decreases the spontaneous electrical activity by 16±4% in pulmonary vein (PV) preparations. Latrunculin B (100 nM) decreases the late Na+ current, L-type Ca2+ current, Na+/Ca2+ exchanger current, and stretch-activated BKCa current in PV cardiomyocytes. Latrunculin B reduces the transient outward K+ current and ultra-rapid delayed rectifier K+ current, but increases the delayed rectifier K+ current in isolated PV cardiomyocytes. Latrunculin B (100 nM) decreases intracellular Ca2+ transient and sarcoplasmic reticulum Ca2+ content in PV cardiomyocytes. Latrunculin B attenuates stretch-induced increased spontaneous electrical activity and trigger activity[2].
