  摘要：

  合成了一系列新型的以稠合杂环为基本核心的血小板受体糖蛋白 (Gp) IIb/IIIa 拮抗剂。在体外试验中，反式-4-(5- 氨甲酰苯并呋喃 -2- 羧酰胺基) 环己氧乙酸 17e 和反式-3-[4-(5- 氨甲酰苯并呋喃 -2- 羧酰胺基)环己基] 丙酸 17f 在人血小板腺苷 -5'- 二磷酸 (ADP) 诱导的聚集试验中分别产生了显著的抑制作用，其 IC50 值分别为 0.018 和 0.006 μM;它们对主要的聚集激动剂 (ADP、胶原蛋白、凝血酶、PMA (肿瘤促进剂) 和花生四烯酸) 也表现出广泛的抑制作用。这些化合物在抑制血小板聚集方面比人脐静脉内皮细胞 (HUVEC) 结合的有效性高出 2-3 个数量级。将 17e 和 17f 以 10 mg/kg 的剂量口服给予豚鼠，5 小时后体外血小板聚集抑制率达到 60%。将反式-4-(5- 氨甲酰苯并呋喃 -2- 羧酰胺基) 环己氧乙酸乙酯 18e (10 mg/kg)口服给予狗，6 小时后血小板聚集抑制率达到 80%，24 小时后恢复到基线水平。反式-3-[4-(5- 氨甲酰苯并呋喃 -2- 羧酰胺基)环己基] 丙酸乙酯 18f (AR0598) 在口服给药后产生了 80% 的抑制作用，持续 5 小时。前药 18e 在狗体内显示出良好的特性，具有较长的作用持续时间。因此，18e (AR0510) 被选为适合开发的口服活性抗血栓药物的候选物。

  The synthesis of a novel series of potent inhibitors of histone deacetylases is described, based on arylsulfinyl-2,4-hexadienoic acid hydroxyamides and their derivatives. In vitro IC(50) values down to 40 nM were obtained, and several compounds showed inhibition of CEM (human leukemic) cell viability with IC(50) of approximately 1.5 microM, comparable to or better than that of suberoylanilide hydroxamic
