  Synthesis and evaluation of anticonvulsant and antidepressant activities of 7-alkyl-7H-tetrazolo[1,5-g]purine derivatives

  摘要：

  Seventeen 7-alkyl-7H-tetrazolo[1,5-g]purine derivatives were synthesized, and their anticonvulsant and antidepressant activities were evaluated in a mouse model. The anticonvulsant effect and neurotoxicity of the compounds were evaluated with a maximal electroshock test and a rotated test in mice, respectively. Most of the compounds had anticonvulsant activity; among the compounds studied, 7-(3-chlorobenzyl)-7H-tetrazolo[1,5-g]purine (3h) was found to be the most potent compound with a median effective dose (ED50) value of 28.9 mg/kg and a protective index value of 15.8, possessing better anticonvulsant activity and higher safety than the marketed drug carbamazepine. To explain the possible mechanism of anticonvulsant activity, compound 3h was tested in pentylenetetrazole-induced seizures tests, and the results suggest that compound 3h exerts anticonvulsant activity through a GABA-mediated mechanism. Forced swimming test showed that at a dose of 40 mg/kg, five compounds have significant antidepressant activity, the most active compound was 7-(2-chlorobenzyl)-7H-tetrazolo[1,5-g]purine (3g), which decreased immobility time by 56 %.

  electroshock-induced seizures (MES) in rats. Most compounds were prepared in three steps from 5-amino-4,6-dichloropyrimidine or in two steps via alkylation of 6-chloropurine. Potent anticonvulsant activity against MES resided in compounds that contain a benzyl substituent at the 9-position of 6-(methylamino)- or 6-(dimethyl-amino)purine. Among commonly used agents for control of seizures, this type of structure represents

  合成了几种9-烷基-6-取代的嘌呤，并测试了其对大鼠最大电击诱发的癫痫发作（MES）的抗惊厥活性。大多数化合物是从3-氨基-4,6-二氯嘧啶分三步制备的，也可以通过6-氯嘌呤的烷基化分两步制备的。针对MES的有效的抗惊厥活性存在于在6-（甲基氨基）-或6-（二甲基-氨基）嘌呤的9位上含有苄基取代基的化合物中。在控制癫痫发作的常用药物中，这种类型的结构代表了一类新型的强效惊厥药物。
