  Riluzole Series. Synthesis and in Vivo “Antiglutamate” Activity of 6-Substituted-2-benzothiazolamines and 3-Substituted-2-imino-benzothiazolines

  摘要：

  Two series of analogues of riluzole, a blocker of excitatory amino acid mediated neurotransmission, have been synthesized: monosubstituted 2-benzothiazolamines and 3-substituted derivatives. Of all the compounds prepared in the first series, only 2-benzothiazolamines bearing alkyl, polyfluoroalkyl, or polyfluoroalkoxy substituents in the 6-position showed potent anticonvulsant activity against administration of glutamic acid in rats. The most active compounds displaying in vivo "antiglutamate" activity were the 6-OCF3 (riluzole), 6-OCF2CF3, 6-CF3, and 6-CF2CF3 substituted derivatives with ED50 values between 2.5 and 3.2 mg/kg i.p. Among the second series of variously substituted benzothiazolines, compounds as active as riluzole or up to 3 times more potent were identified in two series: benzothiazolines bearing a beta-dialkylaminoethyl moiety and compounds with an alkylthioalkyl chain and their corresponding sulfoxides and sulfones. The most potent derivatives were 2-imino-3-(2-methylthio)- and 2-imino-3-(2-methylsulfinyl)-ethyl-6-trifluoromethoxybenzothiazlines (61 and 64, ED50 = 10 and 1.1 mg/kg i.p., respectively). In addition, intraperitoneal administration of some of the best benzothiazolines protected mice from mortality produced by hypobaric hypoxia.

  riluzole respectively. The structures of compounds were confirmed by means of elemental analysis, IR, 1H NMR, and 13C NMR. The synthetic route was optimized and four novel crystals were obtained by recrystallization. This study investigated the antinociceptive activity of some N-alkylated derivatives of riluzole by hot plate test in mice. The relationship between antinociceptive activity and the doses of

  合成了九种利鲁唑的N-烷基化衍生物，以获得具有潜在抗伤害感受活性的新化合物。首先将利鲁唑转化为（6-三氟甲氧基-苯并噻唑-2-基）-肼，然后用SOCl 2氯化，得到2-氯-6-三氟甲氧基-苯并噻唑。该中间产物用九种烷基胺处理，分别得到利鲁唑的N-烷基化衍生物。通过元素分析，IR，1 H NMR和13确认化合物的结构1 H NMR。优化了合成路线，并通过重结晶获得了四个新颖的​​晶体。这项研究通过热板实验在小鼠中研究了利鲁唑的某些N-烷基化衍生物的抗伤害感受活性。研究了抗伤害感受活性与4b，4c，4h，4g和利鲁唑剂量之间的关系。与对照组（0 mg / kg）相比，化合物4b和4h的作用显着增加（分别为13.78±2.89 s，12.89±2.94 s）。化合物4c在小鼠停留在热板上的时间显示出极大的显着增加（18.07±3.08 s）。化合物4b，4c，与空白溶剂组相比，4h增加了潜伏时间
