title: Increased activation of 2',3'-dideoxycytidine by acivicin.
abstract: The effect of acivicin (ACV) on cell growth, cell cycle progression, and intracellular accumulation of 2',3'-dideoxycytidine (ddC) was examined. Treatment of H9 cells with ACV (1 microM) plus ddC (25 microM) for 24 hrs inhibited cell growth to 74 +/- 7%, arrested cells in the S phase, and increased the cellular ddC accumulation to 195-208% of control. The concentrations of ddCTP, the active form of ddC, was increased 3-4 fold in ACV treated cells.
