Pentostatin (I), a tight-binding inhibitor of adenosine deaminase, was evaluated in combination with the partially effective antitumor nucleoside N6-(delta 2-isopentenyl)adenosine (II) for cytotoxic activity against cultured L-1210 lymphocytic mouse leukemia cells. Although I alone (less than or
The adenosine deaminase inhibitor pentostatin (I), recently shown to be effective in the treatment of several types of acute and chronic human leukemias, was impregnated in a silicone polymer monolithic disk device for release in vitro in the presence of the antitumor nucleoside N6-(delta
The use of the aqueous extracts of Eleutherococcus senticosus in combination with either cytarabine or N6-(delta 2-isopentenyl)-adenosine gave additive antiproliferative effects against L1210 murine leukemia. The ED50 for E. senticosus root extracts against L1210 cells was approximately 75
Twenty-one cell lines (six human lines, and nine mouse lines) were compared with respect to inhibition of growth by N-6-(delta-2-isopentenyl)adenosine (IPAR). Six of these, mouse Sarcoma 180, Ehrilich ascites carcinoma, mammary adenocarconoma (TA3), leukemia L1210, mouse kidney, and canine kidney
N6-(delta 2-Isopentenyl)adenosine (I), a nucleoside previously shown to be cytotoxic against several types of tumor cells, was impregnated in silicone polymer monolithic disc devices for release in vitro against lymphocytic mouse leukemia cells. Plotting the cumulative amount of N6-(delta
N6-(delta2-isopentenyl)adenosine was found both as a component of tRNA and as the cytoplasmic mononucleotide in human leukemic lymphoblasts and myeloblasts from peripheral blood and bone marrow samples. This hypermodified nucleotide was also found in the tRNA and as a mononucleotide in human (MRC-5
