the compounds with a phenyl ring in the 6-position of the pyridazine ring exhibited appreciable anticonvulsant activity. Furthermore, a 4-hydroxypiperidine side chain in the 3-position of the pyridazine ring appeared essential for anticonvulsant activity. Substituting the phenyl ring with a Cl in the 2-position led to a substantial increase of activity; disubstituting the phenyl ring with a Cl in the
合成了一系列6-芳基-3-(羟基聚亚甲基氨基)哒嗪衍生物,并评估了其抗惊厥活性。在小鼠中筛选了这些化合物拮抗最大的电击和双小分子诱发的癫痫发作的能力。在转子试验中评估神经毒性。该系列中最有效化合物的抗惊厥活性也已在点燃的杏仁核大鼠和光癫痫性狒狒狒狒中进行了检查。苯巴比妥,二苯乙内酰脲,卡马西平和丙戊酸钠用作标准的抗癫痫药。通过改变哒嗪环6-位的芳基环或修饰3-氨基侧链来检查该系列中的结构活性关系。仅在哒嗪环的6-位具有苯环的化合物显示出明显的抗惊厥活性。此外,哒嗪环的3-位上的4-羟基哌啶侧链似乎对于抗惊厥活性是必不可少的。用2-位的Cl取代苯环导致活性大大增加;在2位和4位上用Cl取代苯环会产生该系列中最有效的化合物,其中一些化合物的功效比苯巴比妥更强。选择了两种化合物6-(2-氯苯基)-3-(4-羟基哌啶子基)哒嗪(2)和6-(2,4-二氯苯基)-3-(4-羟基哌啶子基)哒嗪(3) 。

The synthesis of a series of 6-(substituted-phenyl)-1,2,4-triazolo[4,3-b]pyridazines (VIII) is reported. Some of these derivatives show activity in tests predictive of anxiolytic activity [(a) protection against pentylenetetrazole-induced convulsions; (b) thirsty rat conflict procedure]. They also represent a new class of compound which inhibits [3H]diazepam binding. Structure--activity correlations
报道了一系列6-(取代的苯基)-1,2,4-三唑并[4,3-b]哒嗪(VIII)的合成。这些衍生物中的一些在预测抗焦虑活性的试验中显示出活性[(a)防止戊四唑诱发的惊厥;(b)口渴的老鼠冲突程序]。它们也代表了抑制[3H]地西p结合的一类新化合物。讨论了结构-活性的相关性,以及结构VIII抑制[3H]地西ze结合的能力(体外)。
