Potassium tetrachloroplatinate (K2PtCl4) inactivates dihydropteridine reductase from human brain in a time-dependent and irreversible manner. The inactivation has been followed by measuring enzyme activity and fluorescence changes. The enzyme is completely protected from inactivation by NADH, the pterin cofactor [quinonoid

Cisplatin (cis-diamminedichloroplatinum(II); cis-DDP) is used as an effective drug for treatment of a variety of cancers, such as carcinomas of bladder, ovarian, and testicular origin. Immunopurified DNA polymerase-alpha from rat prostate tumor PA-3 cells was inhibited (50%) in the presence

Expression of the heat-shock protein HSP-60 is associated with poor survival in patients with ovarian carcinoma. We examined both the nature of the interaction between hyperthermia and cisplatin (DDP) using the human ovarian carcinoma cell line 2008 and the effect
We report the DNA binding site preferences of the novel molecule AO-Pt, in which the anticancer drug dichloro(ethylenediamine)platinum(II) is linked by a hexamethylene chain to acridine orange. The sequence specificity of platinum binding was mapped by exonuclease III digestion of
The cellular pharmacology of the tritium-labeled cisplatin analogue dichloro(ethylenediamine)platinum(II) ([3H]DEP) was compared in cisplatin-sensitive 2008 and resistant 2008/C13*5.25 human ovarian carcinoma cells. The cellular content of total [3H], ultrafiltrable [3H], and free native [3H]DEP was measured during and following incubation
