title: [Structure-activity relationships of bronchospasmolytic beta-phenylethyl-aminoalkyl-xanthines (author's transl)].
abstract: Structure-activity relationships of 90 bronchospasmolytic compenylethyl-aminoalkyl-xanthines are reported. Particularly the influence of substituents in the phenyl moiety as well as of the carbon bridge between the xanthine residue and the beta-phenylethylamine moiety is described. 2. A method is shown for the selection of one optimally bronchospasmolytic substance from many potential compounds synthetised via multiple screening steps to profound biological studies.
