Disulfiram (DS), a clinically used anti-alcoholism
6、 drug, strongly inhibits constitutive and5-FU-induced NF-kappaB activity in a dose-dependent manner. Disulfiram inhibits both NF-kappaB nucleartranslocation and DNA binding activity but has no effect on 5-FU-induced IkappaBalpha degradation.Disulfiram significantly enhances the apoptotic effect of 5
