Synthesis and in vitro bronchospasmolytic activity of 8-aryl, heteroaryl or arylalkyl theophyllines
摘要:
Twenty-four 8-aryl- or 8-heteroaryl-substituted theophyllines have been synthesized. The substituents are aromatic rings and heterocycles likely to induce an antiallergic effect or a spasmolytic activity. In vitro evaluation of the bronchospasm caused by acetylcholine or histamine shows an interesting activity for half of the compounds. Among them, the furanic IIIs and 2-chlorophenyl IIIi derivatives are, for instance, four times more active than theophylline.
