title: Synthesis, local anaesthetic and antiarrhythmic activity of methyl N-(2-substituted aminopropanoyl)-3-cyanoanthranilates.
abstract: A series of methyl N-(2-substituted aminopropanoyl)-3-cyanoanthranilates (4a-i), that are structurally-related to tocainide and lidocaine, was synthesized and was found to be active when evaluated for local anaesthetic activity using the frog-foot withdrawal reflex, the guinea pig wheal derm and the rabbit corneal reflex tests. A selected numbers of the series were preliminarily evaluated for antiarrhythmic activity using CaCl2-induced arrhythmia test. Compounds 4a, 4c and 4f at lower doses completely protected the animals against the induced arrhythmias.
