A series of tetracaine analogs based on the lidocaine structure, having a 2'-methyl-(or 2',6'-dimethyl)-4-butylaminoanilide moiety with alpha substitution on the dialkylaminoacyl function, has been synthesized. Local anesthetic activity was found with the N-butyl derivatives in both the 2'-methyl and 2',6'-dimethyl series using both the method of rabbit cornea loss of reflex and spinal anesthesia in
合成了一系列基于利多卡因结构的丁卡因类似物,其具有在二烷基氨基酰基官能团上具有α取代的2'-甲基-(或2',6'-二甲基)-4-丁基氨基苯胺部分。使用兔角膜反射丧失和脊髓麻醉的方法,发现2'-甲基和2',6'-二甲基系列中的N-丁基衍生物均具有局部麻醉活性。化合物的活性持续时间大于利多卡因,但小于丁卡因,且剂量水平相当。
