| In vitro study | The incubation of human plasma with Methionine (D-methionine) and CP leads to the formation of a Pt-D-methionine complex independent of the order of addition. In plasma, an early CP hydrolysis product reacts with Methionine to form a 1:1 complex that is followed by the formation of a 2:1 compound at a later time point. The formation of these Pt-D-methionine species plays an important role in the processes by which Methionine protects mammalian organisms against CP-induced toxicities. |
| In vivo study | When Methionine (D-methionine) is administered along with cisplatin the cell density is 0.8±0.070 (SEM), significantly larger than in rats treated with only cisplatin (P<0.01) while not significantly different from controls or from animals treated only with D-methionine (P>0.05). When Methionine is administered alone the average cell density is 0.95±0.099 (SEM) and not significantly different from controls (P>0.05). |
