The synthesis and antiarrhythmic activity of N-aryl-8-pyrrolizidinealkanamides are described. The target compounds were evaluated for their ability to protect against chloroform-induced fibrillation in mice. Many of them were found to have antifibrillatory activity comparable to that of lidocaine; several are more potent than lidocaine. N-(2,6-Dimethylphenyl)-8-pyrrolizidineacetamide which was found
描述了N-芳基-8-吡咯烷核苷烷酰胺的合成和抗心律失常活性。评价目标化合物在小鼠中预防氯仿诱导的原纤维形成的能力。发现它们中的许多具有与利多卡因相当的抗纤颤活性。有几个比利多卡因更有效。发现N-(2,6-二甲基苯基)-8-吡咯嗪核苷乙酰胺比利多卡因更有效且毒性较低(LD50),口服犬心律失常的狗也表现出长效作用。
