title: [Alkyl and aryl derivatives of isoquinoline. II. Synthesis and pharmacologic activity of dialkylaminoalkyl esters of 1-chloro-3-carboxy-4-methylisoquinoline and the corresponding 4-phenyl derivative].
abstract: The synthesis of a series of dialkylaminoalkylic esters of 1-chloro-3-carboxy-4-methylisoquinoline and of 1-chloro-3-carboxy-4-phenylisoquinoline is described. The pharmacological activity of some of these compounds was studied. The morpholinoethylester of 1-chloro-3-carboxy-4-methylisoquinoline (VIIa), dimethylaminoethylester (VIIb) and diethylaminoethylester (VIIc) showed a good antispasmodic activity. 4-Phenyl-derivatives (XVa), (XVb), (XVc) were more active than analogous 4-methyl derivatives; particularly the diethylaminoethylester of 1-chloro-3-carboxy-4-phenylisoquinoline (XVc) showed an antagonist effect against spasmogens similar to that of papaverine.
