Levosimendan

SKU: orb1305351

Description

Levosimendan (OR1259) is a calcium-sensitizing agent that enhances cardiac contractility by binding to cardiac troponin C, increasing myofilament calcium sensitivity without elevating intracellular calcium levels. It is widely used in cardiovascular research, particularly in studies of heart failure, employing both in vitro assays and in vivo animal models to investigate its inotropic and vasodilatory effects.

Bioactivity

• In Vivo:
  Levosimendan caused contraction and relaxation of failing human cardiomyocytes, with a mean maximum increase in twitch tension of 47% at 0.8 μM Levosimendan.Levosimendan induced a rapid dose-dependent increase in hemodynamic functions in patients with compensated heart failure.Levosimendan caused a significant hyperpolarization (EPS) of resting potential (EPS) in rat mesenteric artery myocytes. The resting potential of rat mesenteric artery myocytes was markedly hyperpolarized by Levosimendan (EC50: 2.9 μM), with a maximal effect at 10 μM (19.5 mV), which may be produced by activation of glibenclamide-sensitive K+ channels.Levosimendan (3 μM) reduced the Ca50 from 2.73 μM to 1.19 μM.
