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.

D007555	Isoxazoles	Azoles with an OXYGEN and a NITROGEN next to each other at the 1,2 positions, in contrast to OXAZOLES that have nitrogens at the 1,3 positions.	Isoxazole
D002453	Cell Cycle	The complex series of phenomena, occurring between the end of one CELL DIVISION and the end of the next, by which cellular material is duplicated and then divided between two daughter cells. The cell cycle includes INTERPHASE, which includes G0 PHASE; G1 PHASE; S PHASE; and G2 PHASE, and CELL DIVISION PHASE.

D016047	Zalcitabine	A dideoxynucleoside compound in which the 3'-hydroxy group on the sugar moiety has been replaced by a hydrogen. This modification prevents the formation of phosphodiester linkages which are needed for the completion of nucleic acid chains. The compound is a potent inhibitor of HIV replication at low concentrations, acting as a chain-terminator of viral DNA by binding to reverse transcriptase. Its principal toxic side effect is axonal degeneration resulting in peripheral neuropathy.	2',3'-Dideoxycytidine,Dideoxycytidine,ddC (Antiviral),HIVID Roche,Hivid,NSC-606170,2',3' Dideoxycytidine,NSC 606170,NSC606170
