Metoprolol (Lanoc; Selopral; Ritmolol; Lopressor; Metomerck; Metop; Toprol) is a potent β1 adrenergic receptor blocker and an approved drug for the treatment of high blood pressure and chest pain.
| ln Vitro |
Metoprolol (0-1000 μg/mL; 24-72 hours) cytotoxic effects on MOLT-4 and U937 cells are dose- and time-dependent [3].
|
|---|---|
| ln Vivo |
In ApoE−/− mice, metoprolol (2.5 mg/kg/h; infusion; 11 weeks) decreases atherosclerosis and pro-inflammatory cytokines [1]. Metoprolol (15 mg/kg/q12h; ig; 5 days) demonstrated antiviral and anti-inflammatory properties in a mouse model of viral myocarditis caused by the coxsackievirus B3 [2]. In rats with coronary microembolism (CME), metoprolol (2.5 mg/kg; intravenous injection; 3 bolus injections) effectively prevented cardiomyocyte death and reduced activated caspase-9 protein expression [4].

| Cell Assay |
Cytotoxicity assay [3]
Cell Types: U937 and MOLT-4 Cell Tested Concentrations: 1, 10, 50, 100, 500 and 1000 μg/mL Incubation Duration: 24, 48 and 72 hrs (hours) Experimental Results: Dramatically diminished viability of U937 and MOLT -4 Cells incubated at a concentration of 1000 μg/mL (3740.14μM) for 48 hrs (hours) Dramatically diminished the viability of U937 cells after incubation at a concentration of ≥500 μg/ml (≥1870.07μM) for 72 hrs (hours), and Dramatically diminished the viability of U937 cells after incubation for 72 hrs (hours). hrs (hours) later, MOLT4 cell concentration was ≥100 μg/ml (≥374.01μM). |
| Animal Protocol |
Animal/Disease Models: Male ApoE−/− mice [1]
Doses: 2.5 mg/kg/h Route of Administration: via mini-osmotic pump, 11 weeks Experimental Results: Thoracic aorta atherosclerotic plaque area Dramatically diminished, serum TNFα and chemokine CXCL1, and diminished macrophage content in plaques. Animal/Disease Models: Balb/c mouse, coxsackie virus B3 (CVB3)-induced viral myocarditis (VMC) model [2] Doses: 15 mg/kg/q12h Route of Administration: po (oral gavage), for 5 days Experimental Results: CVB3 infection-induced reduction in VMC pathology score protects myocardium from viral damage by reducing serum cTn-I levels. Reduce myocardial pro-inflammatory cytokine levels and increase anti-inflammatory cytokine expression. Myocardial virus titers were Dramatically diminished. |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (9.35 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (9.35 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. (Please use freshly prepared in vivo formulations for optimal results.) |

*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.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
