Abstract: In the synthetic plasma, the uptake kinetics of cis-platin and it' s related compounds in human erythrocytes was studied.The experimental results show that the across-membrane transport of all the platinum compounds studied follows a first-order kinetic process in the initial stage.The entry of these compounds into the human red blood cell is considered to follow a passive diffusion mechanism.The uptake rate constants of seven platinum(Ⅱ) compounds were determined.The uptake rates are related to the polarity, charge and hydrolysis rate of the coordination compounds.
