SZL-49是一种能选择性灭活α1a-肾上腺素受体亚型的吡唑嗪类似物,我们在清醒大鼠中评估了SZL-49的外周血流动力学作用。SZL-49给药1 h后,外周血管总阻力和动脉血压明显降低,心输出量和心率明显升高。注射SZL-49 24小时后,血压恢复到注射前控制水平,外周阻力下降,心输出量和心率升高。平均动脉血压和外周血管总阻力的苯肾上腺素剂量-反应曲线右移,但最大反应没有降低。这些数据表明α1受体在动脉血压的滋补维持中起作用。α1受体似乎参与了对外源性激动剂的反应。
The peripheral hemodynamic effects of SZL-49, a prazosin analog capable of selectively inactivating theα1a-adrenoceptor subtype, was evaluated in the conscious rat. One hour after SZL-49 administration, total peripheral vascular resistance and arterial blood pressure significantly decreased and cardiac output and heart rate increased. Twenty-four hours after SZL-49, blood pressure returned to control preinjection levels while peripheral resistance remained decreased and cardiac output and heart rate were elevated. The phenylephrine dose-response curves for mean arterial blood pressure and total peripheral vascular resistance were shifted to the right but the maximal responses were not decreased. These data show that theα1areceptor plays a role in the tonic maintenance of arterial blood pressure. Theα1breceptor appears to participate in the response to exogenously administered agonists.
