Dobutamine tartrate acts quickly and has a brief half-life [2]. In wild-type mice, dobutamine tartrate (0.15–20 mg/kg; intraperitoneally) raises heart rate and left ventricular function in a dose-dependent manner [3]. In wild-type mice, high doses of dobutamine tartrate cause notable inotropic, relaxing, and chronotropic cardiac responses [3]. In Tgαq*44 mice, low-dose dobutamine tartrate markedly improved inotropic and relaxing cardiac performance without causing any alterations to the chronotropic system [3]. Only at large doses does dobutamine tartrate elevate heart rate, but it also causes a loss of relaxing and inotropic cardiac functional reserve [3]. Dobutamine tartrate stimulates β2 receptors to improve alveolar fluid clearance in ventilated rats [4].

Animal/Disease Models: Tgαq*44 mouse (heart failure model) [3]
Doses: low dose 0.15mg/kg, 0.5mg/kg, high dose 1.5mg/kg, 5mg/kg, 20mg/kg: intraperitoneal (ip) injection Experimental Results:Low Low and high doses produced differential responses in cardiac function in mice with heart failure. |

| Additional Infomation |
Dobutamine Tartrate is the tartrate salt form of dobutamine, a synthetic catecholamine with sympathomimetic activity. Dobutamine primarily binds to and stimulates beta-1-adrenergic receptors located in the myocardium. As a result, it leads to a positive inotropic effect and increases in cardiac output.
A catecholamine derivative with specificity for BETA-1 ADRENERGIC RECEPTORS. It is commonly used as a cardiotonic agent after CARDIAC SURGERY and during DOBUTAMINE STRESS ECHOCARDIOGRAPHY. |

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
