A series of N-acyl amino acid analogues of 2 (1H)-quinolinone was synthesized and tested for antiulcer activity against acetic acid-induced gastric ulcer in rats. These compounds were synthesized by the acylation of amino acid derivatives of 2 (1H)-quinolinone, which were obtained from the reaction of ω-bromoalkyl 2 (1H)-quinolinones and acetamidomalonate in the presence of sodium ethoxide, followed by hydrolysis with diluted hydrochloric acid. Among them, 2-(4-chlorobenzoylamino)-3-[2 (1H)-quinolinon-4-yl] propionic acid (VIIIf) was found to have the most potent activity. The structure-activity relationships are discussed.
合成了一系列N-酰基氨基酸类似物的2 (1H)-喹啉酮,并测试了它们对醋酸诱导的大鼠胃溃疡的抗溃疡活性。这些化合物是通过酰化2 (1H)-喹啉酮的氨基酸衍生物合成的,这些衍生物是通过ω-溴烷基2 (1H)-喹啉酮和乙酰胺基丙二酸酯在乙醇钠存在下反应,然后与稀盐酸水解得到的。其中,2-(4-氯苯甲酰氨基)-3-[2 (1H)-喹啉酮-4-基]丙酸(VIIIf)显示出最强的活性。讨论了结构活性关系。
