4-(alkylamino)-1,4-dihydroquinolines is reported. These compounds are novel inhibitors of voltage-activated n-type potassium ion (K+) channels in human T lymphocytes. This series, identified from random screening, was found to inhibit [125I]charybdotoxin binding to n-type K+ channels with IC50 values ranging from 10(-6) to 10(-8) M. These analogs also inhibit whole cell n-type K+ currents with IC50 values from 10(-5)
报道了一系列4-(烷基氨基)-1,4-二氢喹啉的体外生物学表征。这些化合物是人T淋巴细胞中电压激活的n型钾离子(K +)通道的新型抑制剂。从随机筛选中鉴定出的该系列蛋白可抑制[125I]软骨毒素与n型K +通道的结合,IC50值为10(-6)至10(-8)M。这些类似物也可抑制全细胞n型K +电流的IC50值为10(-5)至10(-7)M。描述了一系列新的4-(烷基氨基)-1,4-二氢喹啉的制备。讨论了构效关系。萘基类似物7c(制备的最好的化合物)与[3H]多杀草醚与心脏K +通道的结合抑制作用相比,对[125I]软骨毒素与n型K +通道的结合抑制作用表现出> 100倍的选择性。
