    摘要: This invention relates to novel trans cyclopentanyl purine analogs of the formula (1)

    wherein
       the substituent in the 3-position on the cyclopentanyl ring is in the Trans configuration relative to the bicyclic substituent,
       Y₃, Y₅ Y₇, Y₈ and Y₉ are each independently nitrogen or a CH group,
       R is a hydrogen, a C₁-C₇ alkyl acyl or aryl acyl,
       Q is NH₂, halogen or hydrogen,
       Z is hydrogen, halogen, or NH₂;
    or a pharmaceutically-acceptable salt thereof, and to their use as immunosuppressants.
