  Antiarrhythmic properties of phenylpiperazine derivatives of phenytoin with α1-adrenoceptor affinities

  摘要：

  An association between alpha(1)-adrenoceptor affinities, hERG K+-antagonistic properties and antiarrhythmic activities for a series of phenylpiperazine derivatives of hydantoin (2a-21a) was investigated. New compounds were synthesized and tested for their affinity for alpha(1)-adrenoceptors in radioligand binding assay using [H-3]-prazosin as a selective radioligand. Antiarrhythmic activities in adrenaline-and barium chloride-induced arrhythmia models, an influence of the phenylpiperazine derivatives on the ECG-components and blood pressure were tested in vivo in normotensive rats. The hERG K+-antagonistic properties of the most potent antiarrhythmic agents were investigated in silico by the use of program QikProp. The highest alpha(1)-adrenoceptor affinity (K-i = 4.7 nM) and the strongest antiarrhythmic activity in adrenaline induced arrhythmia (ED50 = 0.1 mg/kg) was found for 1-(4-(4-(2-methoxyphenyl)piperazin-1-yl) butyl)-3-methyl-5,5-diphenylimidazolidine-2,4-dione hydrochloride (19a). The results indicated a significant correlation between alpha(1)-AR affinities (pK(i)) and antiarrhythmic activity (ED50) in adrenaline model (R-2 = 0.92, p < 0.005). Influence of the examined phenylpiperazine hydantoin derivatives on hERG K+ channel, predicted by means of in silico methods, suggested their hERG K+-blocking properties. (C) 2012 Elsevier Ltd.
