274263-65-9: Levosimendan Cyanoacetamide Hydrazone Impurity
It is an impurity present in Levosimendan, Levosimendan increases myofilament calcium sensitivity by binding to cardiac troponin C in a calcium-dependent manner. by stabilizing the calcium-induced conformational change of troponin C by changing actin-myosin. cross-bridge kinetics apparently without increasing the cycling rate of the cross bridges increasing the effects of calcium on cardiac myofilaments during systole, also have a selective phosphodiesterase (PDE)-III inhibitory action. levosimendan acts preferentially as a Ca2+ sensitizer at lower concentrations whereas at higher concentrations its action as a PDE-III inhibitor becomes more prominent in experimental animals and humans.
