(1‐[2‐hydroxy‐3‐(4‐phenyl‐1‐piperazinyl)propyl]‐pyrrolidine) possesses potent antiarrhythmic and a slight hypotensive properties, and affinity for α1‐ and α2‐ adrenoceptor. The results suggest that the antiarrhythmic and hypotensive effect of compound 7 and MG‐1 is related to their adrenolytic properties, and that those properties depend on the presence of a phenylpiperazine moiety.
