Gj. Peters et al., 3-DIMENSIONAL CELL-CULTURES AS A MODEL SYSTEM TO EVALUATE THE BIOLOGICAL-ACTIVITY OF GEMCITABINE (2',2'-DIFLUORO-2'DEOXYCYTIDINE), Nucleosides & nucleotides, 14(3-5), 1995, pp. 661-664
The cytotoxicity of Gemcitabine (dFdC) was 10 (ovarian cancer) to >10,
000 (colon cancer) fold higher in monolayer compared to three-dimensio
nal multilayer cell cultures. This selectivity was related to marked d
ifferences in dFdC activation and effects on ribonucleotides.
