  Structure–activity relationships in a series of 8-substituted xanthines as A1-adenosine receptor antagonists

  摘要：

  A series of X-substituted xanthines were synthesized and their affinity in vitro towards A(1), A(2A)-adenosine receptors was evaluated by radioligand receptor binding assays. All compounds showed a greater affinity and selectivity towards the A(1)-adenosine receptor than theophylline. The compounds in which the n-proyl group is in 1-position of the xanthine nucleus and the pyridazinone system in 8-position is linked through a chain of two or four carbon atoms, showed the highest affinity and selectivity.
