Biological Activity

[Description]:

JTV-519 (K201) is a Ca2+-dependent blocker of sarcoplasmic reticulum Ca2+-stimulated ATPase (SERCA) and a partial agonist of ryanodine receptors in striated muscle. Antiarrhythmic and cardioprotective properties[1][2].

[In Vitro]

JTV-519 (K201) 以剂量依赖的方式抑制由膜联蛋白 V 引起的 Ca2+ 向内移动到大单层囊泡 (LUV)。在 50 nM 膜联蛋白 V 和 400 μM Ca2+ 存在的情况下，3 μM JTV-519 对 Ca2+ 的抑制作用显著，25 μM K201 的抑制作用达到 50%[2]。

[In Vivo]

JTV-519 (0.5mg/kg/h，术前 2 h 静脉注射) 可改善 CLP 小鼠的心功能，其中与未经 JTV-519 处理的 CLP 小鼠相比，分数缩短 (FS) 和射血分数 (EF) 显著增加[3]。 Animal Model: Wild type male C57BL/6 mice weighing 18-22g with polymicrobial sepsis produced by cecal ligation and puncture (CLP) [3] Dosage: 0.5 mg/kg/h Administration: Applied intraperitoneally 2 h before the surgery Result: Improved cardiac function, where the EF and FS were significantly increased.
