showed analgesic and antiinflammatory activities when assayed by the acetic acid writhing test in mice and the carrageenin edema test in rats. To understand how the substituents affect the biological activities, the quantitative structure-activity relationships (QSAR) of 38 compounds were analyzed using the adaptive least-squares method (ALS method). The resulting QSAR suggested that some chemical modifications
当通过小鼠的乙酸扭体试验和大鼠的角叉菜胶水肿试验进行测定时,4,6-二取代的2-(吗啉代羰基)呋喃[3,2-b]吲哚衍生物显示出止痛和抗炎活性。为了了解取代基如何影响生物活性,使用自适应最小二乘法(ALS方法)分析了38种化合物的定量构效关系(QSAR)。最终的QSAR结果表明,对4,6-二取代的呋喃并[3,2-b]吲哚衍生物进行一些化学修饰会改善其生物学活性。因此,合成了另外15种化合物以增强和证实相关性。在这些化合物中,特别是4-(2-乙基己酰基)-2-(吗啉代羰基)-6-(三氟甲基)呋喃[3,2-b]吲哚显示出明显的生物活性。
