Based on the recent observation that the antiplatelet agent ticagrelor and one of its metabolite exert bactericidal activity against gram-positive bacteria, a series of 1,2,3-triazolo[4,5-d]pyrimidines structurally related to ticagrelor were synthesized and examined as putative antiplatelet and antibacterial agents. The aim was to assess the possibility of dissociating the two biological properties and to find novel 1,2,3-triazolo[4,5-d]pyrimidines expressing antiplatelet activity and devoid of in vitro antibacterial activity. The new compounds synthesized were known metabolites of ticagrelor as well as structurally simplified analogues. Some of them were found to express antiplatelet activity and to lose the antibacterial activity, supporting the view that the two activities were not necessarily linked.

基于最近的观察，抗血小板药替卡格雷和其代谢产物之一对革兰氏阳性菌具有杀菌活性，合成并研究了一系列与替卡格雷相关的1,2,3-三唑并[4,5- d ]嘧啶作为推定的抗血小板和抗菌剂。目的是评估解离这两种生物学特性的可能性，并找到表达抗血小板活性且缺乏体外作用的新型1,2,3-三唑并[4,5- d ]嘧啶抗菌活性。合成的新化合物是替卡格雷的已知代谢产物以及结构简化的类似物。发现其中一些表达抗血小板活性并失去抗菌活性，支持了两种活性未必联系在一起的观点。
