Azacitidine

Azacitidine (Vidaza) is used in the treatment of myelodysplastic syndrome. Cells in the presence of azacitidine incorporate it into DNA during replication and into RNA during transcription. The incorporation of azacitidine into DNA or RNA inhibits methyltransferase thereby causing demethylation in that sequence, affecting the way that cell regulation proteins are able to bind to the DNA/RNA substrate.
