JTV-519 hemifumarate (K201 hemifumarate) 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 vivo]
JTV-519 (0.5mg/kg/h, i.v., 2 h before the surgery) improves cardiac function in CLP mice, where the fractional shortening (FS) and ejection fraction (EF) are significantly increased as compared with CLP mice without JTV-519 treatment[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. |
