  A Simple Method for Synthesis of Spongosine, Azaspongosine, and Their Antiplatelet Effects

  摘要：

  Reaction of 2-ethylthioadenine (1) with protected ribose (2) in the presence of stannic chloride gave 2-ethylthioadenosine (4). Oxidation of 5 with potassium permanganate yielded the corresponding sulfone (6) which furnished spongosine (2) after treatment with sodium methoxide. Similarly, reactions of 7-amino-5-ethylthio-1,2,3-triazolo[4,5-d]pyrimidine (8) with the ribose (2) gave 8-azaspongosine (13). The compounds (4) and 2 demonstrated potent antiaggregatory effects both in human platelet-rich plasma and whole blood, whereas, the aza analog (13) showed no inhibitory activity on platelet aggregation. Both (4) and (7) inhibit platelet aggregation in the presence of adenosine deaminase, whereas, adenosine is non-inhibitory, suggesting that analogs (4) and (7) are poor substrates for adenosine deaminase.
