Description

(+)-EMD 57033 is a cardiac troponin C (cTnC) activator, is a dominant Ca2+ sensitizer. (+)-EMD 57033 binds the cardiac/slow skeletal troponin C isoform and exerts myocardial contractile promotion function[1].

IC50 & Target

Cardiac troponin C (cTnC)[1]
In Vitro

(+)-EMD 57033 (30 μM) recovers the activation and sensitivity of Ca2+ in pig single muscle fibres and reduces VIDD (ventilator-induced diaphragm muscle fibre dysfunction) of [2].
(+)-EMD 57033 (5.0-5.8 μM; 10-15 min) significantly increases the coronary blood flow and myocardial V?o2 (O2?consumption) in both 100 bpm and 150 bpm heart rates of rabbit heart, with a [Ca2+]0 concentration-dependent manner ([Ca2+]0=1.0 or 2.5 mM)[3].
(+)-EMD 57033 (5.0-5.8 μM; 10-15 min) increases left ventricular?(LV) end-diastolic pressure and prolongs relaxation[3].

In Vivo

(+)-EMD 57033 (0.4 or 0.8 mg/kg/min; i.v.drip; over than 20 min) enhances contractility and achieves Ca2+ sensitization in intact failing hearts at substantial energetic savings and without compromise of diastolic function in dogs[4].

Animal Model: Mongrel dogs implanted with a micromanometer in left ventricle (LV) at the apex via lateral thoracotomy[4]
Dosage: 0.4 or 0.8 mg/kg/min
Administration: Intravenous drip; infused over 20 minutes
Result: Enhanced contractility at both doses, with similar changes in CON (conscious dogs) and HF (heart failure dogs) hearts.
Decreased the end-diastolic pressure (EDP) and lowered arterial load or preload at 0.8 mg/kg/min.

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (5.88 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
