Used in biochemical research for studying DNA methylation processes due to its ability to inhibit DNA methyltransferases. It serves as a probe to examine epigenetic regulation in cellular systems. Shows potential in anticancer studies by reactivating silenced tumor suppressor genes through demethylation mechanisms. Also utilized in combination therapies to enhance the efficacy of other nucleoside analogs in treating hematological malignancies. Investigated for antiviral applications owing to its structural similarity to natural nucleosides, interfering with viral replication.
