描述 | α2-Adrenoceptors (α2-AR) found in the cardiomyocyte's sarcolemma represent a very important negative feedback for control of myocardial contractility by endogenous catecholamines[2]. Rilmenidine is a clinically approved anti-hypertensive agent that acts by activating ADRA2/α2-adrenoceptors and imidazoline-1 receptors (I1Rs) in the brain and periphery. It can be a mTOR-independent autophagy inducers. Stable inducible PC12 cells expressing either wild-type (23Q) or expanded polyglutamine (74Q) huntingtin both showed a significant increase in LC3-II (microtubule-associated protein 1 light chain) when treated with rilmenidine for 24 h[3]. Sinus rate, corrected sinus recovery time (CSRT) and Wenckebach point (WP) were measured in seven intact dogs. Atrial rate and atrial effective refractory period (AERP) were measured in six atrioventricular (AV)-blocked dogs with ventricular pacing. Each dog received with at least a three-day interval rilmenidine as dihydrogen phosphate in four successive intravenous injections, 30 min apart. In intact dogs, rilmenidine was administered at 50, 50, 100 and 200 μg/kg. In AV-blocked dogs, doses of rilmenidine were 25, 25, 50 and 100 μg/kg. Rilmenidine decreased sinus rate and atrial rate from the first dose. A lengthening of CSRT and a lowering of WP were observed at all doses with rilmenidine. A shortening of AERP was also seen with rilmenidine from the second dose[4]. |
