  Synthesis of 8-Bromo-N-benzylpurines via 8-Lithiated Purines: Scope and Limitations

  摘要：

  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.

  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。

  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.

  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
