  1-Phenylpyrazolo[3,4-d]pyrimidines as adenosine antagonists: the effects of substituents at C4 and C6

  摘要：

  Forty-two 1-phenyl-pyrazolo[3,4-d]pyrimidines substituted at C6 with thioethers containing distal amide substituents and substituted at C4 with thiol, thiomethyl or amino were synthesized and tested for adenosine A(1) and A(2a) receptor binding. Compared with a thiol at C4, both S-methylation and conversion to an amino resulted in increased affinity at both receptors with the C4 amino compounds having the highest affinity. The C-4 region of the receptor consists of an alkyl pocket containing a hydrogen-bonding site. The study established that for high affinity at both the A(1) and A(2a) adenosine receptors the distal amide should be separated from the C6 thiol by only one carbon. In this study, 2'-(4-amino-1-phenylpyrazolo[3,4-d]pyrimidin-6-ylthio)- N-ethyl-ethanamide (4b) had the highest affinity at the A(1) receptor with a K-i of 12.1 nM while 2'-(4-amino-1-phenylpyrazolo[3,4-d]pyrimidin-6-ylthio)ethanamide (4a) had the highest affinity at the A(2a) receptor with a K-i of 44.9 nM.

  Adenosine A2A receptor antagonists are useful for the preparation of medicaments against atrial fibrillation in mammals, including humans. It has been found that the adenosine A2A receptor is present in human atrial cardiomyocytes and participates in the pathological mechanisms underlying atrial fibrillation. An advantage of using A2A antagonists over other agents known in the art is that the A2A antagonists specifically target patients with atrial fibrillation.

  [EN] The invention relates to antagonists of the adenosine A_2A receptor, which can be used for the preparation of medicaments for auricular fibrillation in mammals, including humans. It has been found that the A_2A adenosine receptor is present in human auricular cardiomyocytes and involved in the basic pathological mechanisms of auricular fibrillation. The use of A_2A antagonists is advantageous over other known agents in that A_2A antagonists are directed specifically to patients with auricular fibrillation.

On a découvert que le récepteur d'adénosine A2a est présent dans les cardiomyocytes auriculaires humains et qu'il participe aux mécanismes pathologiques fondamentaux de la fibrillation auriculaire. Il est particulièrement avantageux d'utiliser des antagonistes A2A plutôt que d'autres agents déjà connus dans la technique car ils s'adressent spécifiquement à des patients atteints d'une fibrillation auriculaire.
