  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.

  Treatment of 1, 3, 6-trimethyl-5-nitrouracil with aryl aldehydes in the presence of piperidine results in condensation to the 5-nitro-6-styryluracil derivatives, followed by intramolecular cyclization including piperidine-catalyzed oxidation-reduction to give rise to the corresponding 3-hydroxy-4, 6-dimethylpyrrolo [3, 2-d] pyrimidine-5, 7 (4H, 6H)-dione (9-hydroxy-9-deazatheophylline) derivatives in a single step. Some properties of these compounds and an X-ray crystal structure determination of 8-(p-chlorophenyl)-9-methoxy-7-methyl-9-deazatheophylline are described.

  A number of 1,3-dialkyl-8-(hetero)aryl-9-OH-9-deazaxanthines were prepared and evaluated as ligands of recombinant human adenosine receptors (hARs). Several 1,3-dipropyl derivatives endowed with nano-molar binding affinity at hA(2B) receptors, but poor selectivity over hA(2A), hA(1) and hA(3) AR subtypes were identified. A comparison with the corresponding 7-OH- and 7,9-unsubstituted-deazaxanthines revealed that 9-OH-9-deazaxanthines are more potent hA(2B) ligands with lower partition coefficients and higher water solubility compared to the other two congeneric classes of deazaxanthines. An optimization of the para-substituent of the 8-phenyl ring of 9-OH-9-deazaxanthines led to the discovery of compound 38, which exhibited outstanding hA(2B) affinity (Ki = 1.0 nM), good selectivity over hA(2A), hA(1) and hA(3) (selectivity indices = 100, 79 and 1290, respectively) and excellent antagonist potency in a functional assay on rat A(2B) (pA(2B) = 9.33).
