Latrunculin BCAS No. : 76343-94-7
MCE 國際站:Latrunculin B
產品活性:Latrunculin B 是一種抗菌生物堿,是一種肌動蛋白聚合 (actin polymerization) 抑制劑。Latrunculin B 調節肺靜脈電生理特征并減輕牽張性心律失常的發生。抗真菌和抗原生動物活性。
研究領域:Anti-infection
作用靶點:Fungal
In Vitro: Latrunculin B displays growth inhibition of HeLa cells with an IC50 value of 1.4 μM.
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.
