EMD57033 is a cardiac troponin C (cTnC) activator, a dominant Ca2+ sensitizer, which functions by binding to cardiac/slow skeletal troponin C heterodimers to promote cardiac contraction.

| Description | EMD57033 is a cardiac troponin C (cTnC) activator, a dominant Ca2+ sensitizer, which functions by binding to cardiac/slow skeletal troponin C heterodimers to promote cardiac contraction. |
| In vitro | EMD57033 (5.0 to 5.8 mumol/L) enhances contractility and prolongs relaxation. Its effects are modulated by heart rate, [Ca2+]o, and contraction mode, with positive inotropic effects being more prominent for ejecting beats.[4] |
| In vivo | EMD-57033 (0.4 mg. kg(-1). min(-1) for 20 minutes) selective Ca(2+) sensitization with minimal PDE3I in vivo is achieved, improving basal and rate-stimulated contractility and mechanoenergetics of HF without compromising diastolic function. Despite PDE3I activity at higher doses, energetic benefits persist.[5] |
