Description

Omecamtiv mecarbil (CK-1827452) is a specific cardiac myosin activator and a clinical drug for left ventricular systolic heart failure (in Phase 2 of development). Omecamtiv mecarbil is an inotropic agent that prolongs systolic ejection time and increases ejection fraction through myosin ATPase activation.

50 mg dose (oral) of CK-1827452 (OMECAMTIV MECARBIL) twice a day (BID) for 10 days. Omecamtiv mecarbil infusion (ranging from 0·005 to 1·0 mg/kg per h)

In Vitro Use Guide
In vitro Ventricular myosin (βMys) step-size, motility velocity, and actin-activated myosin ATPase were measured to determine duty cycle in the absence and presence of 1.5 μM OMECAMTIV MECARBIL (OM). A new parameter, the relative step-frequency, was introduced and measured to characterize βMys motility due to the involvement of its three unitary step-sizes. OM decreases motility velocity 10-fold without affecting step-size, indicating a large increase in duty cycle converting βMys to a near processive myosin. The OM conversion dramatically increases force and modestly increases power over the native βMys.
