ABSTRACT
The synthesis, local anesthetic and antiarrhythmic properties, and CNS toxicity of 14 2-(3-alkylaminoalkylamido)-pyrroles are described. Most of the compounds exhibited local anesthetic activity by the guinea pig wheal test, with seven showing comparable or greater activity than lidocaine. Most compounds also exhibited antiarrhythmic activity; three compounds had more potent activity than lidocaine. All compounds exhibiting antiarrhythmic activity also were toxic to the CNS. However, two of the three compounds having greater activity than lidocaine possessed more desirable therapeutic indexes.

The synthesis, local anesthetic and antiarrhythmic properties, and CNS toxicity of 19 2-(2-alkylaminoalkylamido)pyrroles are described. Most of the compounds exhibited local anesthetic activity by the guinea pig wheal test, and four showed activity comparable to or greater than that of lidocaine. Most compounds also exhibited antiarrhythmic activity; five compounds had activity comparable to that of lidocaine, and one was more potent. All compounds exhibiting antiarrhythmic activity also were toxic to the central nervous system.
