Bisoprolol 是一种有效的、选择性的、具有口服活性的 β1 肾上腺素受体 (β1-adrenergic receptor) 阻滞剂，对 β2 受体的活性很小。Bisoprolol 可用于高血压，冠状动脉疾病和稳定的心室功能障碍的研究。
| 生物活性 | Bisoprolol is a potent, selective and orally activeβ1-adrenergic receptorblocker with little activity on β2-receptor. Bisoprolol has the potential for hypertension, coronary artery disease and stable ventricular dysfunction research[1][2]. |
| IC50& Target[1] | Beta-1 adrenergic receptor |

体外研究
(In Vitro) | Bisoprolol (2 μM, 1 h) protects myocardial cells (H9c2) from ischemia/reperfusion (I/R) injury[2].
Bisoprolol (2 μM, 1 h) reduces the H/R-induced ROS production and apoptosis in H9c2 cells[2].
Bisoprolol (2 μM, 1 h) increases AKT and GSK3β phosphorylation in H9c2 cells[2].
Bisoprolol (100 μM, 24 h) reverses Epinephrine-inhibited emigration in cholesterol-loaded DCs (dendritic cell) through increasing in β-arrestin 2, CCR7 and PI3K phosphorylation[3].
Cell Viability Assay[2] | Cell Line: | H9c2 cells | | Concentration: | 0.2, 2, 20 μM | | Incubation Time: | 1 h | | Result: | Elevated the survival rates of cardiomyocytes subjected to H/R (hypoxia/reoxygenation) to 73.20%, 90.38%, 81.25% respectively. |
Cell Migration Assay[3] | Cell Line: | DCs | | Concentration: | 100 μM | | Incubation Time: | 6, 12, 24 h | | Result: | Increased the amount of migrating cells by 46.00% (6 h), 64.25% (12 h) and 55.74% (24 h). |

体内研究
(In Vivo) | Bisoprolol (oral administration, 5 mg/kg, for 1 week) increases left ventricular ejection fraction (LVEF) and decreases the heart rate value[2].
Bisoprolol (oral gavage, 8 mg/kg, daily for four weeks) shows protective effects against Cadmium-induced myocardial toxicity in rats[4].
Bisoprolol (oral gavage, 1 mg/kg, daily for 6 weeks) reverses small conductance calcium-activated potassium channel (SK) remodeling in a volume-overload rat model[5].
| Animal Model: | Ischemia/reperfusion (I/R) injury rats[2] | | Dosage: | 0.5, 5, 10 mg/kg | | Administration: | Oral administration, for 1 week, prior to 0.5 h ischemia/4 h reperfusion. | | Result: | Reduced infarct size from 44% in I/R group to 31% in treated group. |
| Animal Model: | Cadmium-induced rats[4] | | Dosage: | 2, 8 mg/kg | | Administration: | Oral gavage, daily for four weeks. | | Result: | Decreased mean arterial pressure (MAP) at 8 mg/kg.
Decreased serum biomarkers (ALT, AST) and NF-kB p65 expression and TNF-α levels (cardiac tissue samples) at 8 mg/kg. |
