  7-Substituted 5-Amino-2-(2-furyl)pyrazolo[4,3-e]-1,2,4-triazolo[1,5-c]pyrimidines as A_2A Adenosine Receptor Antagonists:  A Study on the Importance of Modifications at the Side Chain on the Activity and Solubility

  摘要：

  It was demonstrated in the early 1990s that adenosine exerts many physiological functions through the interaction with four different receptors, named A(1), A(2A), A(2B), and A(3). In the past few years, our group has been involved in the development of A(2A) antagonists, which led to the synthesis of SCH 58261 (1), the first potent and selective adenosine A(2A) antagonist, which has been widely used as a reference compound. In this paper, we present an extended series of pyrazolotriazolopyrimidines synthesized with the aim to investigate the influence of the substitutions on the pyrazole ring. The choice of the substituents was based on their capability to improve water solubility while retaining high affinity and selectivity at the human A(2A) adenosine receptor subtype. In this series, some structural characteristics that are important for activity, i.e., tricyclic structure, free amino group at 5-position, furan ring, and substituent at 7-position on the pyrazole moiety, have been maintained. We focused our attention on the nature of the phenyl ring substituent to improve water solubility. Following this strategy, we developed new compounds with good affinity and selectivity for A(2A) adenosine receptors, such as 8d (K-i 0.12 nM; hA(1)/hA(2A) ratio = 1025; R-m = 2.8), 8h (K-i 0.22; hA(1)/hA(2A) ratio = 9818; R-m = 3.4), 8i (K-i 0.18 nM; hA(1)/hA(2A) ratio = 994; R-m = 2.8), 8k (K-i 0.13 nM; hA(1)/hA(2A) ratio = 4430; R-m = 3.6), and 14b (K-i 0.19 nM; hA(1)/hA(2A) ratio = 2273; R-m = 2.7). All the new synthesized compounds have no significant interaction with either-A(2B) or A(3) receptor subtypes. This new series of compounds deeply enlightens some structural requirements to display high affinity and selectivity for the A(2A) adenosine receptor subtype, although our goal of identifying new compounds with increased water solubility was not completely achieved. On this basis, other strategies will be devised to improve this class of compounds with a profile that appears to be promising for treatment of neurodegenerative disorders, such as Parkinson's disease.

  名称：

  Pyrazolo[4,3-e]-1,2,4-triazolo[1,5-c]pyrimidine Derivatives:  Potent and Selective A_2A Adenosine Antagonists

  摘要：

  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.
