Conceptually, the direct activation of the cardiac sarcomere can be achieved by either sen-sitizing the regulatory proteins to calcium or ac-tivating cardiac myosin directly. A high-throughput screen of the cardiac myosin adenosine triphos-phatase (ATPase) identified a small-molecule activator of cardiac myosin that was further op-
Omecamtiv mecarbil is a first-in-class cardiac myosin activator, which increases the proportion of myosin heads that are tightly bound to actin and creates a force-producing state that is not associated with cytosolic calcium accumulation.

Novel Inotropic Agents. Omecamtiv Mecarbil. Omecamtiv mecarbil (OM) is the first and most investigated agent in a new class of inotropes called cardiac myosin activators. 33 It exerts its effect by binding on an allosteric site on myosin itself. This leads to a stabilisation of the lever arm of myosin, rendering it primed.
