  Efficient synthesis of 2,9-disubstituted 8-hydroxyadenine derivatives

  摘要：

  一种高效且通用的方法被实现，用于合成预期具有多种生物活性的2,9-二取代的8-羟基腺苷。5-氨基-4-氰基-2-羟基咪唑（1）是从氨基丙腈和异氰酸酯作为关键中间体制备的。将1a与氨基脲、咪唑、胍、尿素和硫脲缩合，得到在2位具有各种取代基的8-羟基腺苷（2–6）。此外，对2-氨基和2-羟基腺苷（4和6）进行选择性烷基化，顺利实现，分别得到相应的2-烷基氨基和2-烷氧腺苷（5和7）。2-烷基硫腺苷（15）是通过1a与苯甲酰异硫氰酸酯的类似反应以及随后S-烷基化制备的。咪唑类化合物1是合成8-羟基腺苷衍生物最有用的中间体。

  Synthesis and evaluation of 2-substituted 8-hydroxyadenines as potent interferon inducers with improved oral bioavailabilities

  摘要：

  In order to create novel compounds which possess potent interferon (IFN) inducing activities with excellent oral bioavailabilities, a series of 8-hydroxyadenines, which have various alkoxy or alkylthio moieties at the adenine C(2)-position, were synthesized and evaluated. The introduction of hydrophobic groups was not considered to be effective for potentiating the IFN-inducing activity, but several compounds having hydrophilic groups were effective. Among the compounds tested, compound 13f induced IFN from the dosage of 0.03 mg/kg, which was approximately 100-fold more potent than that of Imiquimod, and showed an excellent oral bioavailability (F = 40%) which was 10-fold improved over 5, a lead compound (F = 4%).

  9-Benzyl-8-hydroxyadenine (6) was found to possess interferon-inducing activity in vitro as a lead compound. Although replacement of the 9-benzyl group of 6 did not improve the activity, the introduction of a substituent such as alkyl, alkylthio, alkylamino, and alkoxy groups into the 2-position of the adenine ring resulted in a remarkable increase in the activity. The 2-alkylthio (30-32), 2-butylamino (41), and 2-butoxy (47) analogues indicated the highest activities by oral administration to mice.

  A novel synthetic method of 8-oxoadenine derivatives (3 and 4) is reported. This widely applicable synthetic method was realized through the use of 5-aminlo-4-cyano-2-oxoimidazole derivatives (2) as the key intermediates. A variety of substituents were successfully introduced to the 2- and 9-position of the 8-oxoadenine nucleus.
