  合成A3腺苷受体拮抗剂的新策略。

  摘要：

  合成了新的A（3）腺苷受体拮抗剂，并在人腺苷受体亚型上进行了测试。先进的合成策略使我们能够获得大量的关键中间体5，然后将其进行烷基化处理以获得衍生物6-8。然后将这些化合物在5位官能化为尿素（化合物9-11、18和19），以评估其与hA（3）腺苷受体亚型的亲和力和选择性。特别地，化合物18和19分别显示出4.9和1.3nM的亲和力值。从5开始，采用的合成方法使我们能够进行快速便捷的发散合成。进一步的改进使得可以选择性地制备N（8）-取代的化合物7。

  A series of pyrazolo[4,3-e]-1,2,4-triazolo[1,5-c]pyrimidine derivatives (10a-o,q,r), bearing alkyl and aralkyl chains on positions 7 and 8, were synthesized in the attempt to obtain potent and selective antagonists for the A(2A) adenosine receptor subtype. The compounds were tested in binding and functional assays to evaluate their potency for the A(2A) compared with the A(1) adenosine receptor subtype. In binding studies in rat brain membranes, most of the compounds showed affinity for A(2A) receptors in the low nanomolar range with a different degree of A(2A) versus A(1) selectivity. Comparison of N-7 (10a-d,h-o)- and N-8 (10e-g)-substituted pyrazolo derivatives indicates that N-7 substitution decreases the A(1) affinity with the concomitant increase of A(2A) selectivity. Specifically, the introduction of a 3-phenylpropyl group at pyrazolo nitrogen in position 7 (101) increased significantly the A(2A) selectivity, being 210-fold, while the A(2A) receptor affinity remained high (K-i = 2.4 nM). With regards to the affinity for A(2A) receptors, also the compound 10n, bearing in the 7-position a beta-morpholin-4-ylethyl group, deserves attention (K-i = 5.6 nM) even though the A(2A) selectivity (84-fold) was not as high as that of 101. Conversely, the compound 10m (N-7-4-phenylbutyl derivative) showed a remarkable selectivity (A(1)/A(2A) ratio = 129) associated with lower A(2A) affinity (K-i = 21 nM). In functional studies, most of the compounds examined reversed 5'-(N-ethylcarbamoyl)adenosine-induced inhibition of rabbit platelet aggregation inhibition which is a biological response mediated by the A(2A) receptor subtype. The compounds are potent and selective A(2A) antagonists which can be useful to elucidate the pathophysiological role of this adenosine receptor subtype. These compounds deserve to be further developed to assess their potential for treatment of neurodegenerative disorders such as Parkinson's disease.
• Pharmacophore Based Receptor Modeling:  The Case of Adenosine A₃ Receptor Antagonists. An Approach to the Optimization of Protein Models

  To design and synthesize new potent and selective antagonists of the human A(3) adenosine receptor, pharmacophoric hypotheses were generated with the software Catalyst for a comprehensive set of compounds retrieved from previous literature. Three of these pharmacophores were used to drive the optimization of a molecular model of the receptor built by homology modeling. The alignment of the ligands proposed by Catalyst was then used to manually dock a set of known A(3) antagonists into the binding site, and as a result, the model was able to explain the different binding mode of very active compounds with respect to less active ones and to reproduce, with good accuracy, free energies of binding. The docking highlighted that the nonconserved residue Tyr254 could play an important role for A(3) selectivity, suggesting that a mutagenesis study on this residue could be of interest in this respect. The reliability of the whole approach was successfully tested by rational design and synthesis of new compounds.
