  Synthesis and structure–activity relationships of 2-substituted-8-hydroxyadenine derivatives as orally available interferon inducers without emetic side effects

  摘要：

  Recently we reported the adenine derivatives (2-4) as new interferon (IFN) inducers. In the present study, we conducted a detailed structure and activity relationship study of 4 and its related derivatives on IFN inducing activity. From this study, we found that compound 4 exhibited the most potent IFN inducing activity in vitro with a minimum effective concentration of 0.01 muM, and 4 also showed strong IFN-inducing activity at doses of more than 0.3 mg/kg by oral administration in mice. This potency was 10-fold stronger than that of Imiquimod. Moreover, 4 did not cause emesis in ferrets even at doses as high as 10 mg/kg, whereas. 80% of animals, were emetic when orally administered with the same dose of Imiquimod. These results indicate that compound 4 is superior to Imiquimod with respect to efficacy and safety. (C) 2003 Elsevier Ltd. All rights reserved.

• The Suzuki-Miyaura Cross-Coupling Reactionsof 2-, 6- or 8-Halopurines with Boronic Acids Leading to 2-, 6- or 8-Aryl- and -Alkenylpurine Derivatives

  日期：——

  The Suzuki-Miyaura cross-coupling reactions of 9-benzyl-6-chloropurine, 9- or 3-benzyl-8-bromoadenine and 2,6-dihalopurines with boronic acids gave the corresponding 6-, 8- or 2-aryl- or -alkenylpurines in good yields. Anhydrous conditions in toluene were superior for coupling of electron-rich boronic acids, while aqueous DME was used for electron-poor arylboronic acids as well as for alkenylboronic acids. A good regioselectivity was observed for the coupling of 2,6-dihalopurines: 9-benzyl-2,6-dichloropurine reacted with one equivalent of phenyl boronic acid to give 9-benzyl-2-chloro-6-phenylpurine, while an analogous reaction of 9-benzyl-6-chloro-2-iodopurine gave selectively 9-benzyl-6-chloro-2-phenylpurine.

  9-苄基-6-氯嘌呤、9-或3-苄基-8-溴腺嘌呤及2,6-二卤嘌呤与硼酸进行的铃木-宫浦交叉偶联反应，以良好产率得到了相应的6-、8-或2-芳基或烯基嘌呤衍生物。无水条件下以甲苯为溶剂对于富电子硼酸的偶联反应较为有利，而贫电子芳基硼酸及烯基硼酸则以含水的二甲氧基乙烷(DME)为溶剂进行反应。在2,6-二卤嘌呤的偶联反应中可以观察到良好的区域选择性：9-苄基-2,6-二氯嘌呤与一当量苯硼酸反应得到了9-苄基-2-氯-6-苯基嘌呤，而9-苄基-6-氯-2-碘嘌呤的类似反应则高选择性地得到了9-苄基-6-氯-2-苯基嘌呤。

  the 2-, 6- and/or 8-position have been prepared and screened for antimycobacterial effects. High inhibitory activity against Mycobacterium tuberculosis was found for 9-benzylpurines carrying a phenylethynyl-, trans-styryl or aryl substituents in the 6-position and generally chlorine in the 2-position tends to increase activity.

  -1,2,3-triazolo[4,5-c]pyridines were prepared and assayed as A1 adenosine receptor ligands. The 1H-1,2,3-triazolo[4,5-c]pyridines were obtained starting from N,N-diethyl-1-benzyl-4-carboxyamido-5-methyl-1H-1,2,3-triazole by lithiation in anhydrous tetrahydrofurane in the presence of benzonitrile. The usual work up afforded the isolation of 1-benzyl-6-phenyl-1H-1,2,3-triazolo[4,5-c]pyridin-4-one which

  Some 1-[4-(9-benzyl-2-phenyl-9H-purin-6-ylamino)-phenyl]-3-phenyl-urea derivatives and some 1-[4-(9-benzyl-2-phenyl-9H-8-azapurin-6ylamino)-phenyl]-3-phenyl-urea derivatives were synthesised and evaluated for their interaction with adenosine receptors. It was found that some of these compounds can act as positive enhancers of agonist and antagonist radioligands for the A(2A) adenosine receptors. This evidence was also strengthened by functional data. Other compounds can act as negative modulators. Furthermore these compounds show inhibitory properties for A(1) and A(3) adenosine receptors.
