A novel series of 2, 2-dialkyl-1'-(N-substituted aminoalkyl)-spiro-[chroman-4, 4'-imidazolidine]-2', 5'-diones was synthesized and evaluated for antiarrhythmic activity in chloroform- or/and aconitine-induced ventricular arrhythmia in mice. Among these compounds, (-)-6-chloro-2, 2-dimethyl-1'-[3-(4-hydroxypiperidino)propyl]-spiro-[chroman-4, 4'-imidazolidine]-2', 5'-dione was found to be more effective than reference agents and was selected for further development.
合成了一系列新型的2, 2-二烷基-1'-(N-取代氨基烷基)-螺-[色满-4, 4'-咪唑烷]-2', 5'-二酮化合物,并评估了其在氯仿或/和乌头碱诱导的小鼠心室心律失常中的抗心律失常活性。在这些化合物中,(-)-6-氯-2, 2-二甲基-1'-[3-(4-羟基哌啶基)丙基]-螺-[色满-4, 4'-咪唑烷]-2', 5'-二酮被发现比参考药物更有效,并被选作进一步开发。
