[New biologically active theophylline derivatives. Synthesis and pharmacologic properties of flufylline and fluprofylline].

Within the course of the research project for finding new cardiovascular drugs we have synthetized since 1976 piperazine- and piperidine derivatives of theophylline. The screening shows for the substances Sgd 19578 (flufylline) and Sgd 14480 (fluprofylline) a long-lasting blood pressure lowering activity as well as a remarkable serotonin- and histamine antagonism and broncholytic activity. On the basis of these results these compounds were selected for further investigation.
