The interaction between the targeted liposome of containing linoleic platinum and tumor cell membranes was studied by method of 3- maleimide-2, 2, 5, 5-tetramethyl-1-pyrrolidinyloxyl spin label (MSL). The targeted liposome of containing linoleic platinum effects on ESR spectrum of tumor cells labeled with MSL. In the presence of linoleic platinum the ratios of W and S of breast cancer cell membranes and S180 cell membranes labeled with MSL were changed, The results indicate linoleic platinum can react with mercapto groups on the proteins of tumor cell membranes and change the conformations of cell membrane proteins.

Key words: LIPOSOME, ANTICARCINOGEN, ELECTRON SPIN RESONANCE, BREAST CANCER
