The antitumour agent 5-(3,3-dimethyl-1-triazeno) imidazole-4-carboxamide (DTIC) inhibits rat liver cAMP phosphodiesterase and amplifies hormone effects in hepatocytes and hepatoma cells.

The antitumour agent 5-(3,3-dimethyl-1-triazeno)imidazole-4-carboxamide (DTIC) was found to inhibit competitively the low-Km cyclic AMP phosphodiesterase activity in an ammonium-sulphate-precipitable fraction of the 2,000g supernatant of rat liver. With substrate concentration at 0.25 microM, I50 wa...
