Isoprenaline HCl is an agonist of β-adrenergic receptor [1].
The adrenergic receptors are a class of G protein-coupled receptors that are targets of norepinephrine and epinephrine. When reacting with epinephrine, β-adrenergic receptor causes vasodilation.
In human umbilical vein endothelial cells (HUVECs), isoprenaline (100 nM) significantly increased the expression of connexins Cx43 and also increased Cx40 and Cx37. Also, isoprenaline increased the number of coupling cells. Isoprenaline enhanced the formation of branches and complex tube networks [2].
In the isolated field stimulated rat vas deferens, isoprenaline inhibited contractions with EC50 value of 45.6 nM. In tissues in which β 2-adrenoreceptors were maximally blocked by timolol, isoprenaline inhibited contractility with EC50 value of 1.5 μM [1]. In CFW mice, IPR caused the maximal proliferative response of bone marrow cells and increased erythropoietic activity. These results suggested that isoprenaline activated beta-adrenergic receptor, which then increased the proliferative and differentiation activities of hemopoietic stem cells [3].

|
Cell lines |
Human umbilical vein endothelial cells (HUVECs) |
|
Reaction Conditions |
100 nmol/L isoprenaline for 20 h incubation |
|
Applications |
Isoprenaline resulted in significantly enhanced expression of endothelial Cx43 and to a lower degree of Cx40 and Cx37. The number of coupling cells was significantly increased. Regarding angiogenesis, isoprenaline led to significantly enhanced formation of branches and a higher complexity of the tube networks with more branches/length. |
| Animal experiment:[2] | |
|
Animal models |
Male albino rats of the Sprague-Dawley strain, 225 ~ 325 g |
|
Dosage form |
0.33 mg/kg Administered by subcutaneous injection |
|
Applications |
A subcutaneous injection of 0.33 mg/kg isoproterenol decreased blood pressure and increased water intake in nephrectomized rats. |
