  Synthesis and Structure-Activity Relationships of Deazaxanthines: Analogs of Potent A1- and A2-Adenosine Receptor Antagonists

  摘要：

  A set of 22 9-deazaxanthines (pyrrolo[3,2-d]pyrimidine-2,4-diones) and three 7-deazaxanthines (pyrrolo[2,3-d] pyrimidine-2,4-diones) with various substituents in the 1-, 3-, 7- or 9-, and 8-positions was synthesized and investigated in A1 and A2a adenosine receptor binding assays at rat brain cortical membranes and rat brain striatal membranes, respectively. 9-Deazaxanthines showed structure-activity relationships that were similar to those of xanthines. They were about equipotent to the corresponding xanthines at A2a adenosine receptors. 9-Deazaxanthines were generally at least 2-3-fold more potent than xanthines at A1 receptors and therefore exhibited higher A1 selectivities compared to the xanthines. 1,3-Dimethyl-8-(2-naphthyl)-9-deazaxanthine (19e) showed high affinty (K-i = 26 nM) and selectivity for A1 adenosine receptors. A hydroxyl function at N7 of 9-deazaxanthines was unfavorable for A1 and A2a receptor binding. 7-Deazaxanthines were considerably less potent compared to xanthines and to 9-deazaxanthines at both receptor subtypes.

  A new series of 9-deazaxanthine derivatives with various substituents at the heterocyclic system were synthesized and evaluated for their binding affinities for the four human recombinant adenosine receptors, A(1)-A(3) subtypes. A number of the 9-deazaxanthines derivatives 3a-m showed moderate-to-high affinity for hA(2B) receptors, with compound 3f showing a 32-fold selectivity for A(2B) over A(1) and a 2750-fold selectivity for A(2B) over A(2A).
