OMecaMtiv Mecarbil Usage And Synthesis

Description

Omecamtiv mecarbil (CK-1827452) is a specific cardiac myosin activator and a clinical drug for left ventricular systolic heart failure. Phase 2.

In vitro

In vitro, Omecamtiv mecarbil selectively activates cardiac myosin by increasing the myosin ATPase rate. In isolated cardiac myocytes, Omecamtiv mecarbil results in increase of myocyte contractility and overcomes of the myosin inhibitor BDM without increasing the calcium transient or inhibiting the PDE pathway. [

In vivo

Omecamtiv mecarbil significantly increases fractional shortening starting at 0.4 mM plasma concentrations in SD rats, sham animals and in rats with heart failure. In conscious dogs with myocardial infarction (MI-sHF), Omecamtiv mecarbil leads to a significant increase in wall thickening (25%), stroke volume (44%), cardiac output (22%) and left ventricular (LV) systolic ejection time (26%). In addition, Omecamtiv mecarbil also results in the decreases of some hemodynamic parameters including heart rate, mean left atrial pressure, and LV end-diastolic pressure. In conscious dogs with left ventricular hypertrophy (LVH-sHF), Omecamtiv mecarbil leads to similar and not statistically different effects on hemodynamic parameters.

Uses

CK 1827452 is a promising new drug in systolic heart failure. It accelerates the transition of myosin into the force-generating state without affecting cardiac myocyte calcium homeostasis. CK 1827452 increases cardiac function by increasing the duration of ejection without changing the rates of contraction.

Definition

ChEBI: Omecamtiv mecarbil is a member of ureas.

Biological Activity

omecamtiv mecarbil (ck-1827452) is the first potent cardiac myosin activator that can specifically activate the cardiac myosin s1 domain but not other muscle myosins. in
