Deoxyribonuclease activities in human leukemic cells and mouse lymphoblasts

1975

Summary The deoxyribonuclease activities from human lymphocytes have been compared with the activities from acute lymphocytic leukemic cells and mouse leukemic cells L5178Y using the in situ detection of deoxyribonucleases in DNA-containing polyacrylamide gels following their separation by micro-disc-electrophoresis. A neutral deoxyribonuclease activity is completely missing in leukemic cells of untreated patients while a group of acid deoxyribonuclease activities is increased. A similar deoxyribonuclease pattern can be seen in L5178Y cells. Under medical treatment the increment of the acid deoxyribonuclease activities disappears and the neutral deoxyribonuclease activity reappears.

N-[2-(Triphenylphosphonio)ethoxycarbonyl] -[Peoc-]asparaginsaure-benzylester (8h) und -tert-butylester (8i) werden mit 2-Acetamido-3,4,6-tri-O-acetyl-2-desoxy-β -D-glucopyranosylamin (2) zu den N4-Glycosylasparagin-Derivaten 19 verknupft. Aus diesen kann die Peoc-Gruppe selektiv mit Diethylamin/tert-Butylalkohol oder Morpholin/Methylendichlorid abgespalten werden, wobei in den entstandenen N4-Glycosylasparaginestern 22 alle anderen Schutzgruppen und die glycosidische Bindung erhalten bleiben. Durch Kondensation von 22 mit Peoc-Aminosauren 8 entstehen die voll geschutzten N4-Glycosylasparagin-Dipetide 24 und 30. Bei Kondensation der N2 deblockierten N4-Glycosylasparaginester 22 mit den Peoc-…
