    摘要: A novel, unique nucleoside, 3-.beta.-D-ribofuranosyl-3,6,7,8-tetrahydroimidazo[4,5-d][1,3]diazepin-7-ol, named isocoformycin, of the formula ##STR1## is provided by ring expansion of derivatives of 9-.beta.-D-ribofuranosyl-6-hydroxymethyl-1,6-dihydropurine. Isocoformycin markedly inhibits deaminating enzymes which inactivate formycin and adenine arabinoside (also known as ara-A and Vidarabine). Formycin and adenine arabinoside are used as antiviral and antitumor agents in mammals and birds and isocoformycin is advantageous to prolong the activity and effect of formycin and adenine arabinoside.
