compounds containing one tetrahydroisoquinoline ring and than an open phenetylamine ureide. (c) Trans compounds are more active than their cis isomers. (d) Aryl substituents are better than alkyls at the isoquinoline C-1 position. (e) Electron-withdrawing substituents lead to higher activities. The most potent compound is the 4-F derivative, with IC50 in the 10–8 M range and selectivities around 1000:1 for
包含嵌入式尿素功能的四氢异喹啉衍生物被鉴定为选择性TRPM8通道受体拮抗剂。研究了结构与活性之间的关系,得出以下结论:(a)尿素功能和四氢异喹啉系统是活性所必需的。(b)双(1-芳基-6,7二甲氧基-1,2,3,4-四氢异喹啉基)脲比含有一个四氢异喹啉环和开放的苯乙胺胺的化合物更具活性。(c)反式化合物比其顺式异构体更具活性。(d)在异喹啉C-1位置的芳基取代基优于烷基。(e)吸电子取代基导致更高的活性。最有效的化合物是4-F衍生物,IC 50在10中对于大多数其他TRP受体,–8 M的范围和选择性在1000:1左右。发现所选化合物在减少LNCaP前列腺癌细胞的生长中具有活性。TRPM8抑制作用可减少测试的肿瘤细胞的增殖,但不能减少非肿瘤前列腺细胞的增殖,这表明抗前列腺癌的活性与TRPM8抑制作用有关。
