A series of N, N-disubstituted-ω-(1, 2-dihydro-2-oxoquinolyloxy) alkanecarboxamides was synthesized and tested for inhibitory activity towards collagen- and ADP-induced aggregation of rabbit blood platelet in vitro. These compounds were prepared by the reaction of ω-(1, 2-dihydro-2-oxoquinolyloxy) alkanoic acid and various amines by the mixed anhydride method. Among them, N-cyclohexyl-N-(2-hydroxyethyl)-4-(1, 2-dihydro-2-oxo-6-quinolyloxy) butyramide (IVa1) was found to have the most potent inhibitory activity. The structure-activity relationships are discussed.
合成了一系列 N,N-取代的ω-(1, 2-二氢-2-氧羟喹啉氧基)烷基氨基酸酰胺,并对其在体外对胶原和ADP诱导的兔血小板聚集的抑制活性进行了测试。这些化合物是通过ω-(1, 2-二氢-2-氧羟喹啉氧基)烷酸与各种胺反应,采用混合酸酐法制备的。其中,N-环己基-N-(2-羟乙基)-4-(1, 2-二氢-2-氧-6-喹啉氧基)丁酰胺(IVa1)被发现具有最强的抑制活性。文中讨论了结构-活性关系。
