A series of mesoionic xanthines (e.g. mesoionic thiazolopyrimidines, 3, and thiadiazolopyrimidines, 5) and related analogues were examined as inhibitors of human platelet aggregation. Appropriately substituted compounds were found to fully inhibit platelet aggregation, and anhydro-(6-ethyl-8-isopentyl-7-oxo-5-hydroxy-1,3,4-thiadiazolo[3,2 -a]pyrimidinium hydroxide) (5b) was 40 times more potent than
研究了一系列中离子黄嘌呤(例如,中离子噻唑并嘧啶3,和噻二唑并嘧啶5)和相关类似物作为人类血小板聚集的抑制剂。发现适当取代的化合物可完全抑制血小板凝集,并形成脱水-(6-乙基-8-异戊基-7-氧代-5-羟基-1,3,4-噻二唑[3,2-a]氢氧化嘧啶鎓)(5b )的效力是与结构相关的黄嘌呤茶碱(1)的40倍。凝胶过滤研究表明,化合物5b不可逆地抑制聚集,这可能是由于其充当潜在的酰化剂的能力。
