  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 %.

  6-（烷基氨基）-9-苄基-9H-嘌呤。一类新的抗惊厥药。

  摘要：

  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。

  Adenine derivatives substituted in position 9 have been demonstrated to have potent cyclic nucleotide phosphodiesterase (PDE) inhibition properties with high selectivity toward PDE-4. Starting from our initial lead compound 9-(2-fluorobenzyl)-N(6)-methyl-2-trifluoromethyladenine (4, NCS613), we designed and synthesized a new series of 9-substituted derivatives for developing structure-activity relationship

  已经证明在9位取代的腺嘌呤衍生物具有有效的环核苷酸磷酸二酯酶（PDE）抑制特性，并且对PDE-4具有高选择性。从我们最初的先导化合物9-（2-氟苄基）-N（6）-甲基-2-三氟甲基腺嘌呤（4，NCS613）开始，我们设计并合成了一系列新的9-取代衍生物，用于开展结构-活性关系研究。这一系列新的衍生物显示出更高的效价和更好的选择性。在腺嘌呤环的三个不同位置上并行完成结构修饰，并得到以下观察结果：（i）引入亲脂性取代基（如三氟甲基），C-2位的正丙基或碘对于PDE-4抑制活性和对其他同工酶的选择性都有利；（ii）用2-甲氧基取代基对N9苄基进行官能化，导致活性更高的化合物；（iii）用其他氨基取代N（6）-甲基氨基部分对活性是有害的。在所有制备的衍生物中，9-（2-甲氧基苄基）-N（6）-甲基-2-三氟甲基腺嘌呤（9r），9-（2-甲氧基苄基）-N（6）-甲基-2-n-丙基腺嘌呤（9s） ），

  A series of new purines containing triazole and other heterocycle substituents was synthesized and evaluated for their preliminary anticonvulsant activity and neurotoxicity by using the maximal electroshock (MES), subcutaneous pentylenetetrazole (scPTZ) and rotarod neurotoxicity (TOX) tests. Among the compounds studied, 9-decyl-6-(1H-1,2,4-triazol-1-yl)-9H-purine (5e) was the most potent compound,

• Synthesis of 8-Bromo-<i>N</i>-benzylpurines via 8-Lithiated Purines: Scope and Limitations

  日期：2010.8.16

  9-Benzylpurines have been lithiated in the 8-position and subsequently brominated when trapped with BrCCl2CCl2Br. The 8-bromopurines were isolated in excellent yields when the benzyl group carried an alkoxy or alkyl group in the ortho or para position. Without these substituents, the conversion was generally less, and formation of 8,8'-purinyl dimers was observed. There was also evidence of debenzylation in some instances. Bromination of 7-benzylpurines employing the same set of reaction conditions has also been achieved.
• Synthesis, Biological Activity, and SAR of Antimycobacterial 9-Aryl-, 9-Arylsulfonyl-, and 9-Benzyl-6-(2-furyl)purines

  日期：2005.4.1

  9-Aryl-, 9-arylsulfonyl- and 9-benzyl-6-(2-furyl)purines were synthesized by N-alkylation or N-arylation of the purine followed by Stille coupling to introduce the faryl substituent in the 6-position and the compounds screened for activity against Mycobacterium tuberculosis. The 9-aryl- and 9-sulfonylarylpurines exhibited weak activity toward the bacteria, but 9-benzylpurines were good inhibitors especially those carrying electron-donating substituents on the phenyl ring. A chlorine atom in the purine 2-position further enhanced activity. The high antimycobacterial activity (MIC 0.39,mu g/mL against M. tuberculosis), low toxicity against mammalian cells and activity inside macrophages found for 2-chloro-6-(2-furyl)-9-(4-methoxyphenylmethyl)9H-purine makes this compound a highly interesting potential antituberculosis drug.
