The kinetics of the aquation reactions of cisplatin and carboplatin and their subsequent reactions with DNA, both in vitro and in vivo, have been measured. The results have been extrapolated to indicate the expected cytotoxicity of these compounds in cells obtained from human cancer patients. Rate constants for the aquation at 37 degrees C of cisplatin and carboplatin of 8 X 10(-5) and 7.2 X 10(-7) s-1, respectively, were calculated from the half-life of these compounds in phosphate buffer, pH… CONTINUE READING
