产品介绍
(R)-(-)-Phenylephrine HCl 是一种选择性 α1-adrenoceptor 激动剂,对于 α1D, α1B 和 α1-adrenoceptor 激动剂的 pKis 分别为 5.86、4.87 和 4.70。

Animal experiment:

Rat: A total of 170 male Wistar rats are randomLy allocated into 17 groups (n=10) using random number tables. Short-term (40 minutes) mechanical ventilation with high tidal volume is performed to induce lung injury, impair active Na+ transport and lung liquid clearance in the rats. Unventilated rats serves as controls. To demonstrate the effect of phenylephrine on alveolar fluid clearance, phenylephrine at different concentrations (10, 1, 0.1, 0.01, and 0.001 μM) is injected into the alveolar space of the HVT ventilated rats[5].

产品描述

(R)-(-)-Phenylephrine hydrochloride is a selective α1-adrenoceptor agonist with pKis of 5.86, 4.87 and 4.70 for α1D, α1B and α1A receptors respectively.

(R)-(-)-Phenylephrine is a selective α1-adrenoceptor agonist with pKi values of 5.86, 4.87 and 4.70 for α1D, α1B and α1A receptors respectively[1][2]. Phenylephrine promotes cardiac fibroblast proliferation. Phenylephrine activates CaN and evokes NFAT3 nuclear translocation. It suggests that the Ca(2+)/CaN/NFAT pathway mediates phenylephrine -induced cardiac fibroblast proliferation, and this pathway might be a possible therapeutic target in cardiac fibrosis[3].

Perfusion of hearts with 100 μM phenylephrine causes a rapid (maximal at 10 min) 12-fold activation of two p38-MAPK isoforms. α1-adrenoceptor agonists such as phenylephrine increase the contractility of the heart. Phenylephrine also activates SAPKs/JNKs in neonatal ventricular myocytes[4]. Phenylephrine could increase the alveolar fluid clearance in high tidal volume-ventilated rats and accelerate the absorption of pulmonary edema[5].
