  • Abstract
  • Look Inside

One of the serious problems in chemotherapy of brain tumors is that tumor cells are able to acquire resistance to initially effective cytotoxic agents. In order to study the mechanism of this resistance against chemotherapeutic agents, especially ACNU, two variant cell lines (C6/ACNU and 91,/ACNU) re-sistant to ACNU [1-(4-amino-2-methyl-5-pyrimidinyl) methyl-3-(2-chloroethyl)-3-nitrosourea hydrochloride] were selected previously in vivo from rat C6 glioma and 9Lgliosarcoma, respectively. Uptake and re-tention of ACNU in these resistant cells were studied with [14C]ACNIT.
