5、 (DNA-methylating) 。Streptozocin 引起肝臟，腎臟及胰腺DNA 甲基化，但腦 DNA 中沒有甲基化。IC50 & Target DNA alkylator 1體外研究 Streptozocin (STZ) shows higher cytotoxic effect in vitro on hematological cell lines compared to Alloxan(ALX). ALX appeares not to be toxic for the studied cell lines with estimated IC50 values of 280

6、9, 3679 orover 4000 g/mL for HL60, K562 and C1498 cells, respectively. Streptozocin is more toxic, especially for thehuman myeloid leukemia cell line, HL60. The IC50 values of Streptozocin are 11.7, 904 and 1024 g/mL forHL60, K562 and C1498 cells, respectively. Results also show that the murine leuk

7、emic cells are moreresistant to Streptozocin and ALX cytotoxicity than human leukemic cells 2.體內(nèi)研究 Streptozocin (STZ)-injected mice show tendency to have lower body weight than that observed in animalsinjected with ALX.

9、0 g/mL) for 48 h at 37C under a humidified atmosphere containing 5% CO2. Cells incubated in completemedia including dH2O in a final concentration of 0.1% served as control for solvent toxicity and cellsincubated in complete medium are used as a control for the experiments.
