Abstract: | The synthesis of a series of dialkylaminoalkylic amides of 1-chloro-3-carboxy-4-methylisoquinoline (VIII), of 1-methoxy-3-carboxy-4-methylisoquinoline (VI) and of 3-carboxy-2,4-dimethyl-1-oxoisoquinoline (XIII) is described. In addition a series of 1-amino-substituted 3-carboxymethyl-4-methylisoquinolines (II) was synthesized. The pharmacological activity of some of these compounds was studied. The compounds (XIIIa), (VIa) and (VIIIa) showed a clear local anaesthetic activity, a little lower than that of lidocaine; the same compounds also showed fairly good antispasmodic properties. |
