Various 1-[1-[2-[3-(alkylamino)-2-hydroxypropoxy]phenyl]vinyl]-1H-azoles were synthesized and investigated for β-adrenoceptor-blocking and antiarrhythmic activities. Although no compounds showed more potent β-blocking effects than propranolol in the isolated guinea pig right atria, many compounds exhibited significant antiarrhythmic effects against aconitine or ischemic arrhythmia in mice or dogs. 1-[2,5-Dichloro-6-[1-(1H-imidazol-1-yl)ethenyl]phenoxy]-3-[(1-methylethyl) amino]-2-propanol hydrochloride (48) (711389-S) was selected as a candidate for clinical evaluation in man, since its antiarrhythmic effects were superior to those of quinidine, disopyramide, or propranolol. Asymmetric synthesis of (R)-(+)- and (S)-(-)-48 is described, and it is proven that there is no stereospecificity in the antiarrhythmic effect of 48.
