体外研究 (In Vitro) |
Metoprolol (0-1000 μg/mL; 24-72 h) shows cytotoxic effect on U937 and MOLT-4 cells dose and time dependently[3].
Cell Cytotoxicity Assay[3]
Cell Line: |
U937 and MOLT-4 cells |
Concentration: |
1, 10, 50, 100, 500 and 1000 μg/mL |
Incubation Time: |
24, 48 and 72 h |
Result: |
Significantly decreased the viability of U937 and MOLT-4 cells at 1000 μg/mL (3740.14μM) concentration after 48 hours incubation time, significantly reduced the viability of U937 cells at ≥500 μg/ml (≥1870.07μM) concentrations after 72 hours incubation time, and significantly decreased the viability of MOLT4 cells at ≥100 μg/ml (≥374.01μM) concentrations after 72 hours incubation. |

体内研究 (In Vivo) |
Metoprolol (2.5 mg/kg/h; infusion; 11 weeks) reduces proinflammatory cytokines and atherosclerosis in ApoE–/–Mice[1]. Metoprolol (15 mg/kg/q12h; i.g.; 5 days) shows anti-inflammation and anti-virus effects in murine model with coxsackievirus B3-induced viral myocarditis[2]. Metoprolol (2.5 mg/kg; i.v.; 3 bolus injections) significantly decreased activated caspase-9 protein expression and inhibits myocardial apoptosis in coronary microembolization (CME) rats[4].
Animal Model: |
Male ApoE–/–mice[1] |
Dosage: |
2.5 mg/kg/h |
Administration: |
Via osmotic minipumps, 11 weeks |
Result: |
Significantly reduced atherosclerotic plaque area in thoracic aorta, reduced serum TNFα and the chemokine CXCL1 as well as decreasing the macrophage content in the plaques. |
Animal Model: |
Balb/c mice, coxsackievirus B3 (CVB3) induced viral myocarditis (VMC) model[2] |
Dosage: |
15 mg/kg/q12h |
Administration: |
Oral gavage, 5 consecutive days |
Result: |
Reduced pathological scores of VMC induced by CVB3 infection, protected the myocardium against viral damage by reducing serum cTn-I levels. Decreased the levels of myocardial pro-inflammatory cytokines and increase the expression of anti-inflammatory cytokine. Significantly decreased myocardial virus titers. |
