The nature of in vivo cell-killing of deoxyspergualin, and its implication in combination with other antitumor agents.
The mode of in vivo cell-killing by 15-deoxyspergualin (NKT-01) was assessed by measuring change of whole body radioactivity of mice inoculated with 125I-iododeoxyuridine-labeled P388 leukemia cells. Although NKT-01 showed strong life prolonging effect on P388 leukemia-bearing mice, significant excretion of 125I was not observed within 4 days after the start of treatment with NKT-01. Thereafter...

like any other learning activity, translation is a problem solving activity which involves executing parallel cognitive processes. the ability to think about these higher processes, plan, organize, monitor and evaluate the most influential executive cognitive processes is what flavell (1975) called “metacognition” which encompasses raising awareness of mental processes as well as using effectiv...
Preclinical antitumor activity and pharmacological properties of deoxyspergualin.
A new antibiotic, deoxyspergualin (DSG), demonstrated antitumor activity against L1210 leukemia in mice. The life span of mice bearing either i.p. or s.c.-implanted L1210 increased greater than 150% following i.p. administration of 25 mg/kg DSG on days 1-9. Activity obtained with i.p. bolus treatments was schedule dependent. The tumor burden in mice bearing the s.c. implanted L1210 was reduced ...
متن کاملAntitumor activities of (2"R)-4'-O-tetrahydropyranyl-adriamycin (THP) and its combination with other antitumor agents on murine tumors.
(2''R)-4'-O-Tetrahydropyranyladriamycin (THP) is a new derivative of doxorubicin (adriamycin, ADM). The concentrations of THP and ADM required to inhibit by 50% the growth of a cultured L1210 cells was 0.003 microgram/ml and 0.016 microgram/ml, respectively. Various therapeutic designs of combinations of THP with other antitumor agents were investigated in vivo using the L1210 murine leukemia. ...
