Abstract:
In vitro drug resistance was induced against cis-diamminedichloroplatinum(II) (cis-DDP), 1,2-diaminocyclohexaneplatinum-(II)citrate (PEX) and 1,2-diaminocyclohexaneplatinum(II)glucarate (PTU) in L1210 leukemia cell line. Using the resistant sublines cross-resistance was found between cis-DDP and cis-diamminecyclobutane-1,1-dicarboxylatoplatinum(II) (CBDCA) and between the three 1,2-diaminocyclohexane (DACH) derivatives tested. No (or low degree) cross-resistance was found between cis-DDP and DACH derivatives.
