    摘要: As novel substances having an activity of inducing an apoptosis even on the apoptosis-resistant cancer cells, there are obtained polyoxypeptin and deoxypolyoxypeptin represented by the following general formula (I) wherein R denotes a hydroxyl group for polyoxypeptin, or R denotes a hydrogen atom for deoxypolyoxypeptin, by cultivation of Streptomyces sp. MK498-98F14 strain. Polyoxypeptin and deoxypolyoxypeptin are physiologically active substances which have an activity of inducing apoptosis on a human pancreatic adenocarcinoma cell, AsPC-1 cell.

    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.
