title: Synthesis and antitumor and antiviral activities of 1-beta-D-arabinofuranosyl-2-amino-1,4(2H)-iminopyrimidine and its derivatives.
abstract: 1-beta-D-Arabinofuranosyl-2-amino-1,4(2H)-imino-5-fluoropyrimidine (10), 1-beta-D-arabinofuranosyl-2-amino-1,4(2H)-imino-5-fluoropyrimidine 3'-phosphate (9), and 1-beta-D-arabinofuranosyl-2-amino-1,4(2H)-imino-5-chloropyrimidine (11) have been synthesized from 2,2'-anhydro-1-beta-D-arabinofuranosyl-5-fluorocytosine (5), 2,2'-anhydro-1-beta-D-arabinofuranosyl-5-fluorocytosine 3'-phosphate (4), and 2,2'-anhydro-1-beta-D-arabinofuranosyl-5-chlorocytosine (6), respectively. 2,2'-Anhydro-1-beta-D-arabinofuranosylcytosine 3'-phosphate (7), 1-beta-D-arabinofuranosyl-2-amino-1,4-(2H)-iminopyrimidine (13), 1-beta-D-arabinofuranosyl-2-amino-1,3(2H)-iminopyrimidine 3'-phosphate (12), and compounds 4, 5, and 9 showed significant in vitro activity against a number of DNA viruses. Compounds 7 and 12 were also effective in vivo against type 1 herpes simplex virus. Compounds 7, 12, and 13 were extremely effective in the treatment of mice bearing leukemia L1210.
