A number of N-[4-[4-(1H-indol-3-yl)piperidinoalkyl]-2- thiazolyl]alkanesulfonamides (8--21) were synthesized and evaluated for their preventive effects on systemic anaphylaxis in guinea pigs. Structure-activity analysis revealed that methane- and ethanesulfonamide derivatives having a one to three methylene tether between the piperidine and thiazole rings exhibited potent activity but the introduction
合成了许多N- [4- [4-(1H-吲哚-3-基)哌啶子基烷基] -2-噻唑基]烷磺酰胺(8--21),并评估了它们对豚鼠全身过敏反应的预防作用。结构活性分析表明,在哌啶和噻唑环之间具有1-3个亚甲基醚的甲烷和乙磺酰胺衍生物显示出强活性,但是在吲哚部分引入取代基降低了活性。对小鼠施用(100 mg / kg po)四种化合物8、9、12、13以及酮替芬,奥托米特,特非那定和氮卓斯汀作为参考化合物,对小鼠显示,仅化合物8不会引起由下列药物引起的睡眠时间显着增加己烯比妥。另外,化合物8(10 mg / kg iv)不会改变清醒兔子的脑电图。这些结果导致选择N- [4- [4-(1H-吲哚-3-基)哌啶子甲基] -2-噻唑基]甲磺酰胺(8,FK613)作为新的抗过敏剂进行进一步开发。FK613的临床评估目前正在进行中。
