title: [Study of the cardiovascular properties of some new methyl-xanthine derivatives].
abstract: The effects of some new methylxanthine compounds, derivatives of theophylline, theobromine and caffeine with various radicals in 8 position on blood pressure have been studied. Derivatives of theophylline (1,3-dimethyl-xanthine) with various radicals in 8 position have reduced the blood pressure. In the same experimental conditions the theobromine (3,7-dimethyl-xanthine) derivatives haven't modified the blood pressure while the caffeine (1,3,7-trimethyl-xanthine) derivatives have increased the blood pressure values.
