title: Synthesis of arabinofuranosyl derivatives of 3-deazaguanine.
abstract: Synthesis of four arabinofuranosyl derivatives of the antitumor agent 3-deazaguanine is described. By the use of 13C and 1H nuclear magnetic resonance spectroscopy, the structures of these nucleosides were established to be alpha and beta pairs of N-7 and N-9 arabinosides of 3-deazaguanine. In contrast to 3-deazaguanine and its ribosyl derivative, the nucleosides described in this paper were found to be inactive against Sarcoma 180 in mice at 100 mg/kg.
