Dihydro-5-azacytidine (DHAC), the nucleoside analog, is incorporated into DNA and inhibits DNA methylation. Dihydro-5-azacytidine has an antitumor activity[1][2].

In Vitro	Methylation studies show that an LD10 dose of [3H]DHAC results in a 25.06% hypomethylation of DNA in L1210/0 cells and a 46.32% hypomethylation in a deoxycytidine kinase mutant cell line L1210/dCK(-), compared with their respective controls[2]. Dihydro-5-azacytidine (DHAC) competes with cytidine triphosphate for incorporation into RNA, leading to ribosomal degradation and defective protein synthesis[1].
In Vivo	In tumor-bearing mice (injected with L1210/0 cells), after an LD10 dose of Dihydro-5-azacytidine (DHAC; 1500 mg/kg), the plasma peak concentration achieved is 317 μM and is eliminated biexponentially, with a t1/2 α of 1.03 h and a t1/2 β of 5 h[2].
