title: Inhibition of Meth-A tumor cell proliferation in combined use of disulfiram with catalase.
abstract: The effect of combined use of disulfiram with catalase on Meth-A tumor cell proliferation was studied. The simultaneous addition of 5 x 10(-7) or 1 x 10(-6) M disulfiram with catalase (4-40 micrograms/ml) induced marked inhibition of cell proliferation. A moderate degree of the antiproliferative effect was also obtained by pretreatment of the target cells with 5 x 10(-6) or 1 x 10(-5) M disulfiram in the presence of catalase (40 micrograms/ml). These results suggest that compounds or metabolites with cytostatic activity are newly formed following the reaction of disulfiram with catalase.
