  Synthesis and purine receptor affinity of 6-oxopurine nucleosides and nucleotides containing (N)-methanocarba-pseudoribose rings

  摘要：

  6-Oxopurine derivatives containing a northern (N) methanocarba modification (i.e., fused cyclopropane and cyclopentane rings in place of the ribose) were synthesized and the adenosine receptor affinity measured. Guanine or hypoxanthine was coupled at the 7-position, or 1,3-diblitylxanthine was coupled at the 9-position. The pseudoribose ring was also substituted at the 5 ' -position with an N-methyluronamide or with phosphate groups. Published by Elsevier Science Ltd.

  Locked in translation: Crucial insight into the ribosomal catalysis of peptide‐bond formation is expected to be gained from the target compounds, which feature conformational locking in a North‐type pucker, designed to interfere with the translation of the genetic code. The compounds were prepared from D‐ribose in 18 and 19 steps by a multi‐step synthetic route described here (see scheme).

  锁定翻译：可以从目标化合物中获得对肽键形成的核糖体催化作用的重要见解，这些化合物具有构象锁定在North- type pucker中的功能，旨在干扰遗传密码的翻译。这些化合物是由D-核糖按照此处所述的多步合成路线分18步和19步制备的（请参见方案）。
