A new series of 8-(substituted-phenyl)xanthines have been synthesized and compounds were evaluated for their affinity for A1 and A2 adenosine receptors (AR) using radioligand binding assays. The effects of varying the positions of 8-phenyl substituents on affinity and selectivity at A1 and A2A adenosine receptors have been studied. Isovanilloid 1,3-dimethyl-8-[4-methoxy-3-(2-morpholin-4-ylethoxy)phenylxanthine
The aldehyde derivatives of 1,3-dipropyl xanthines as described in this paper, constitutes a new series of selective adenosine ligands displaying bronchospasmolytic activity. The effect of substitution at 3rd - and 4th -position of 8-phenyl xanthine has also been taken into consideration. The synthesized compounds showed varying binding affinities at different adenosine receptor subtypes (A1 , A2A
