Chemical and pharmacological properties of some 7-beta-hydroxy-gamma-piperazinopropyl-8-benzylaminotheophylli nes.
In order to examine the circulatory and bronchospasmolytic activity, new 7-beta-hydroxy-gamma-N4-alkylpiperazinopropyl-8- benzylaminotheophyllines (1, 2, 3) were synthesized and converted to the water soluble dihydrochlorides (1a, 2a, 3a). They showed hypotensive and bronchodilatory effect.
